| 61 | Dual capacity fluid pump | JP12785591 | 1991-05-30 | JPH04234588A | 1992-08-24 | GUREN II SUWANSON; UIRIAMU JIEI HAAREI |
| PURPOSE: To provide a dual capacity pump which has a simple structure and which can reduce the manufacturing cost, by incorporating two constant volume pump-up elements each of which is commonly provided with a one-way flow valve and a flow control valve device responding to a degree of a pressure signal. CONSTITUTION: A gear pump is formed therein with three gear openings 12, 14, 16 having common parts in which they are partly overlapped with one another, and incorporated therein, respectively, with outer gear pump elements, that is, pump-up elements 18 driven by an engine. A high pressure feed port 36 for each pair of gear elements 18, 20 is communicated with a feed passage 38 extending to a control device in an automatic transmission or the like, through a passage 40 and a one-way check valve 42. The passage 40 is communicated with a valve chamber 44 in a flow control valve 46 which controls the communication between passages 32, 54 in such a way that a valve spool 46 is displaced, overcoming a spring 56, in accordance with a pressure in a control pressure passage 66 which is controlled by a control orifice 69.

CONSTITUTION:Two sets of pump mechanisms PA, PB are arranged with line symmetry with respect to a center line C in a pump casing 5 formed by fixing a flange 3 and a cover 4 to the front and rear of a middle case 2. The pump mechanisms PA, PB respectively have gears 6A, 7A and 6B, 7B respectively meshing with each other and respectively provided with common outlets 8A, 8B for respective gear sets. Driving one gear 6A, the other three gears 7A, 6B, 7B are made to be driven. Suction ports 15E, 15F are formed at positions displaced by about 180 deg. from the outlets 8A, 8B in the middle case 2 are made to be connected to a common suction port 16 bored in a cover 4. | ||||||

| Example fluid circuits (e.g., within aircrafts) include first (12) and second (32) pump assemblies. The first pump assembly has an electric motor (18) and a first fluid pump (16). The first fluid pump is coupled to the electric motor and has a case drain port (30) that is in fluid communication with a case drain region of the first fluid pump. The second pump assembly is powered by hydraulic pressure from the first fluid outlet (22) of the first fluid pump and functions to augment flow through the case drain region of the first fluid pump. | ||||||

| There is disclosed an improved pump (5, 5') particularly suitable for use in a method of "artificial lift" in an oil/gas well. Known pumps used in artificial lift methods suffer from a number of problems/disadvantages - e.g. low efficiency (hydraulic efficiency). The disclosed embodiments of the invention provide a pump (5, 5') which provides a positive displacement of a predetermined volume of well production fluid for each operative cycle of the pump - in contra-distinction known to pumps which provide axial flow of well production fluid. The inventive pump (5, 5') provides a chamber (10, 10') having a volume (V, V'), an inlet (15) to the chamber (10, 10'), an outlet (20) from the chamber (10, 10'), and means for varying the volume (V, V') of the chamber (10, 10'). The means for varying the volume (V, V') of the chamber (10, 10') is controlled by relative rotation of first and second bodies (30, 35; 30', 35'). | ||||||

| A hydraulic transmission circuit is provided having at least two elementary hydraulic motors, each having a secondary enclosure and a main duct for fluid feed and a secondary enclosure and a main duct for fluid discharge. A fluid distributor distributes fluid from the main ducts to the elementary motors via the secondary enclosures. A control system controls the elementary motors. Valves connecting the fluid distributor to the secondary enclosures of the first motor put a secondary enclosure into communication with a main duct independent of an operating mode of any other elementary motor. | ||||||

| An apparatus for use in turning steerable vehicle wheels includes a power steering motor assembly connected with the steerable vehicle wheels. A first pump connected with the power steering motor assembly is continuously driven by an engine of the vehicle, during operation of the engine, to supply fluid under pressure to the power steering motor assembly. A second pump connected with the power steering motor assembly is continuously driven by an engine of the vehicle, during operation of the engine. A valve connected with the power steering motor assembly and the second pump directs fluid flow from the second pump to at least one of the power steering motor assembly and reservoir during operation of both the first pump and the second pump. A pumping mechanism includes a first pumping area defining the first pump and a second pumping area defining the second pump. The first pumping area is smaller than the second pumping area. | ||||||

| A vane pump includes a first cam ring and a second cam ring, a first rotor positioned in the first cam ring and a second rotor positioned in the second cam ring, and a shaft. The first rotor is engaged with the shaft so that the first rotor rotates relative to the first cam ring about an axis extending through the shaft, and the second rotor selectively engages with the shaft so that the second rotor selectively rotates relative to the second cam ring about the axis. A piston positioned in the shaft translates within the shaft between a first position and a second position. When in the first position, the shaft engages with the second rotor so that the second rotor rotates relative to the second cam ring about the axis, and when in the second position, the shaft disengages with the second rotor so that the second rotor does not rotate relative to the second cam ring. | ||||||
