More particularly, this disclosure relates to those hydraulic automatic transmission bicycles which use fluid pressure to change such gear ratios, and which include various hydraulic automatic transmissions which may be provided in various configurations and may operate in various methods and sequences to provide automatic and infinitely variable gear ratios. | ||||||
| 142 | VANE PUMP WITH ADJUSTABLE DELIVERY VOLUME | US15305973 | 2015-02-17 | US20170045047A1 | 2017-02-16 | Johannes Burdiak; Richard Vogt; Uwe Zellner |
| The invention proposes a vane pump (VP) with adjustable delivery volume, which vane pump has a pump housing (G), a cam ring (KR) arranged therein, and a rotor (R) which is rotatably movably mounted therein. The vane pump (VP) has a regulating device (RV) through which the delivered pressure medium (DM) flows and which has two outlets (A1, A2) which are each connected to one of two pressure chambers (DK1, DK2) in order to charge these with regulable proportions of the pressure medium (DM), wherein, to change the eccentricity of the cam ring (KR) relative to the rotor (R), the two pressure chambers (DK1, DK2) act on the outer surface of the cam ring (KR). The vane pump (VP) has two criss-crossing control ducts (STK*, STK#) which connect in each case one of the outlets (A1, A2) to one of the two pressure chambers (DK1, DK2) in order to charge these with the regulable proportions of the pressure medium (DM). The criss-crossing control ducts (STK*, STK#) are preferably arranged in a cover (D′) of the pump housing such that the control ducts (STK*, STK#) are in a criss-crossing arrangement without coming into contact with one another. By means of this design, the vane pump (VP) can be easily reconfigured for a change in rotational direction of the rotor. | ||||||
| 143 | Fluid pump for a linear actuator | US14082606 | 2013-11-18 | US09500206B2 | 2016-11-22 | Jared Ret Zammuto |
| A fluid pump for a linear actuator is provided. The pump causes a rod in the actuator to extend or retract by controlling the flow of fluid to and from portions of a fluid chamber on either side of a piston disposed within the fluid chamber and supporting the rod. The pump includes a valve structure that enables the pump to redistribute fluid obtained from one portion of the fluid chamber on one side of the piston to the other portion of the fluid chamber on the other side of the piston without first returning the fluid to a fluid reservoir thereby increasing the efficiency of the pump. | ||||||
| 144 | TURBOMACHINE WHICH CAN BE OPERATED BOTH AS HYDRAULIC MOTOR AND AS PUMP | US15028192 | 2014-10-08 | US20160252083A1 | 2016-09-01 | Reginald R. BAUM; Robert ROSS |
| A turbomachine that can be operated as a motor and as a pump, having an axially fixedly mounted shaft, including a power section with rotating inlet and outlet and an associated controller. Because the axial forces (Fgx) have been made independent of the sense of rotation the turbomachine is significantly more reliable, and because the sealing forces have been adjusted it has significantly greater reliability (η) in both running directions. It can be operated with fluids and gases. The turbomachine can be extended by adding a control device and a drive for the control device so as to provide a freewheel function, a braking function and/or blocking function, and so as to shift, modify and optimize the characteristic curves across the entire control range. In both the clockwise and anticlockwise directions the turbomachine has in principle the same properties, although these can be modified and optimized by the control device. | ||||||

| 160 | Lubrication pump for inter-axle differential | US10935308 | 2004-09-08 | US06997841B2 | 2006-02-14 | Lawrence P. Wagle; Dale Kwasniewski; James F. Ziech |
| An inter-axle differential assembly comprises an input shaft, an output shaft arranged coaxially with respect to each other, differential gearing and a dedicated reversible lubrication pump disposed between the input and output shafts. The reversible gerotor type lubrication pump includes a rotor driven by the input shaft, and an impeller, both disposed within a pump body coupled to a side gear drivingly connected to the output shaft. Thus, the lubrication pump generates lubricant flow only during the differential action between the input shaft and the output shaft, i.e. only when needed and at a flow rate proportional to the speed difference across the differential assembly. An oil flow generated by the lubrication pump is supplied to various components of the inter-axle differential assembly through a gallery of fluid passages. | ||||||
