The invention relates to a high pressure cleaning device comprising a motor driving an internally toothed gearwheel pump for supply of a cleaning fluid, under high pressure, to an outlet device. Said internal tooth gear and/or an external tooth gear comprise a molybdenum containing chrome steel alloy which also contains a nitrogen component of 0.1 - 1 % and which increases the corrosion resistance and hardness of the toothed gearwheels.
262 Compact sealless screw pump EP99302047.8 1999-03-17 EP0943804A1 1999-09-22 Sloteman, Donald P.

A screw pump includes a pump case (100) having a fluid inlet (112), a pumping chamber and a fluid discharge (113) with at least two intermeshed parallel screw members (125) rotatably mounted therein and in fluid communication with the fluid inlet and discharge. One synchronous drive electric motor (120) mounted to each screw member provides the driving power to the screws. Electronic controls are provided for sensing the rotary positions of the motors for synchronising rotation of the screw members. The pump is also capable of pumping multi-phase fluids.

The present invention pertains to a rotary piston regulating device (1) intended for measuring flowable or pourable material, either powdery or granulous. In a cylinder casing (4), a rotary piston is arranged so as to form, in the area of the peripheral surface (18), so tight an area in relation to the cylinder inner surface (6) that, when the cylinder is rotating for each cycle, a working chamber (22) is defined - extending from an inlet area (8) - to receive a certain volume of said material. In order for the volume fed to the working chamber (22) to be modulated, a regulating valve (6) radially adjustable relative to the cylinder casing (4) causes the opening (W) of a slot (40) situated between the rotary piston (14) and the piston-oriented valve end (36) to vary. For intermittent adjustment of the feed slot (40) in each cycle, the valve (36) is radially actuated in both directions by means of a control member (42) depending on the rotary piston rotation (14).

Die Erfindung betrifft eine Solaranlage mit in einem Solarkreislauf eines Wärmeträgermediums eingebundenen Solarkollektor (13), Wärmetauscher (5) und Zirkulationspumpe. Sie betrifft außerdem eine Zahnradpumpe (9), insbesondere für Solaranlagen zur Zirkulation eines Wärmeträgermediums, mit einem Pumpengehäuse (91), in dem zwei Zahnräder (93, 94) ineinandergreifend drehbar gelagert sind, und einem Pumpengehäusedeckel (92).

Erfindungsgemäß erzeugt die Zahnradpumpe einen für eine "Low-Flow-Solaranlage" ausreichenden Betriebsdruck bei dem gewünschten relativ geringen Förderstrom. Die Zahnradpumpe sperrt bei Stillstand den Solarkreislauf, so daß eine unerwünschte Rückzirkulation mit einfachen Mitteln vermieden wird.

Die Mikropumpe (1) besteht aus einer Hülse (60), in der fünf Funktionselemente teilweise beweglich und teilweise fest integriert sind, wobei im Fall der "festen Integration" Funktionselemente, die keine relative Bewegung zueinander ausführen oder deren Funktion eine feste Verbindung erfordert auch aus einem Teil bestehen können, wenn dies die Fertigung zuläßt. An jeder Stirnseite der Hülse (60) ist jeweils ein Stirneinsatz (41) bzw. (42) vorgesehen, die beide eine außermittige Bohrung zur Aufnahme einer Pumpenachse (50) aufweisen. Die Bohrungen fluchten entlang einer ersten Achse (100), die gegenüber der Mittenachse (101) der Hülse (60) nach radial außen geringfügig versetzt ist.

The invention relates to a pumping process for operating a multi-phase screw pump with at least one feed screw surrounded by a housing having at least one intake stub on one side and at least one discharge stub at its top, in which the intake medium is conveyed parallel to the screw shaft in a continuous low-pulsed stream and continuously discharged at the discharge stub. The invention also relates to a multi-phase screw pump. In order to prevent the drawbacks usually occurring in dry running phases, the invention proposes that a partial liquid volume flow (liquid circulation) be separated on the pressure side and returned in metered quantities into the intake region and thus kept in circulation.
269 Integral pump and flow meter device EP95850235.3 1995-12-27 EP0722044A3 1997-01-15 Johnson, Paul A

A pump housing (11) is provided with a conduit (32) extending through the housing between a pump inlet (34) and pump outlet (36). A pump device (38) is disposed within the housing and in communication with the conduit to pump fluid therethrough. A fluid flow meter (42) also is disposed within the housing and in communication with the conduit (32) to monitor fluid flow rate through the conduit. The fluid flow meter generates signals related to the fluid flow rate which are fed back to a control device (50) operable to control the flow rate through the pump device. The flow meter may include a pair of meshed modified elliptical gears. The modified elliptical gears are based on a true elliptical shape, with bulged portions added between the major and minor axes of the elliptical shape. The modified elliptical gears have involute teeth that are relatively thick adjacent the minor axis and relatively thin adjacent the major axis.

271 Gear metering pump for compounded elastomeric material EP92105580.2 1992-04-01 EP0508285A1 1992-10-14 Greenstreet, Arthur William; Norka, Joseph C.

A gear metering pump (1) for delivering precise amounts of a compounded elastomeric material (2) into a die (3). The gear pump (1) has a housing (20) formed with a hollow interior chamber (21) containing a pair of rotating meshing gears (40,41) mounted on shafts (42,43), one of which is power driven, for passing controlled quantities of the compounded material out of the chamber and into the die (3). A side plate is removably mounted on the housing and encloses an open side of the chamber (21) and is moved between open and closed positions by fluid pressure cylinders (67) mounted on the housing to provide ready access into the chamber for cleanout. A first bearing assembly (34,35) for the gear shafts (42,43) is mounted on the removable side plate (30) and retains the gears (40,41) mounted thereon for removing the gears (40,41) from within the chamber (21) along with the side plate (30). Outlet openings (59,60,76,80,51) are formed in the removable side plate (30) and in an opposite fixed side plate (31) adjacent the shafts (42,43) and bearings (34,35,37,38), permitting small quantities of the compounded material (2) to flow between the shafts (42,43) and bearings (34,35,37,38) and out of the openings for lubrication of the bearings (34,35,37,38). The drive shaft passes out of the housing (20) through an enlarged opening and is free of any end seal with the housing to reduce heat buildup.

277 Oil supply apparatus for engine provided with two-stage relief valve EP12172117.9 2012-06-15 EP2674583A1 2013-12-18 Kwon, Hyuk In; Kim, Jin Yong

Provided is an oil supply apparatus for an engine provided with a two-stage relief valve, in which a sufficient amount of working fluid is supplied in proportion to an engine speed in a low speed range where sufficient lubrication is not performed and a flow rate of the working fluid is reduced in a medium and high speed range where smooth lubrication is performed to reduce a rotational load applied to a crankshaft, capable of reducing an engine load to decrease fuel consumption to improve fuel efficiency as well as improving a lubrication operation through supply of an appropriate flow rate.

278 TWIN-SCREW LIQUID PUMP EP10859796.4 2010-11-30 EP2642125A1 2013-09-25 TANG, Yan

A double-screw liquid pump is provided, which is applicable to an Organic Rankin Cycle (ORC). The double-screw liquid pump includes a semi-sealed or fully sealed shell, and the shell includes a first cavity and a second cavity isolated from each other. A motor is disposed in the first cavity, and a main body part of a double-screw is disposed in the second cavity. At least one rotor of the double-screw is fixedly connected to a rotor of the motor, and the double-screw rotates through driving of the motor. A liquid refrigerant injection inlet and a refrigerant outlet are disposed on the first cavity, and the motor is cooled through evaporation of a liquid refrigerant; a liquid inlet and a liquid outlet are disposed on the second cavity. In the double-screw liquid pump applied to the ORC provided in the present invention, since a resistance torque of the female rotor is very small, the liquid pump does not wear even when the liquid viscosity is very low, contributing to good reliability, and thereby improving power generation efficiency of the ORC. In addition, the semi-sealed or fully sealed shell can effectively prevent leakage of the refrigerant.
