摘要： The present invention relates to a system that provides independently operated or controlled circuits in a single device. An exemplary application adapts a variable displacement roller pump into an engine geometry control system that uses one circuit of the pump during start-up and then removes the circuit from the system and satisfies other pumping needs with the other circuit of the pump.

摘要： A fuel delivery system (10) comprises a variable displacement pump (20) for pressurizing fuel. The variable displacement pump has a distinct first pump displacement setting for a first desired mass flow of fuel and a distinct second pump displacement setting for a second desired mass flow of fuel. The variable displacement pump operates in only one of the first and second pump displacement settings. A fuel control (22) with a metering valve downstream of the variable displacement pump selectively regulates fuel delivery.

摘要： A bearing assembly is provided for a fuel delivery system that includes a pump (10) having a housing that rotatably receives a rotor (20) carrying vanes (26) thereon, a cam ring (70) received between the housing and rotor (20), and a support member of yoke (50) encompassing the cam ring (70) to selectively vary fuel flow. The bearing assembly (80) is a journal bearing between the yoke (50) and the cam ring (70) and includes an annular surface having a central opening therethrough. The annular surface includes a first, high pressure pad (102) and a second, low pressure pad (104) substantially diametrically opposite the first pad and separated by first and second lands (106, 108). The circumferential extent of the first pad (102) is at least as great as an inner diameter of the cam ring (70). Circumferential ends of the second pad (104) are wider than circumferential ends of the first pad. The first and second pads (102, 104) are formed by circumferentially extending grooves that extend an entire width of the bearing so that the cam ring moves between the first and second pads, and thereby varies a clearance between the lands (106, 108) and the cam ring (70).

摘要： A fuel system for providing a desired fuel flow to an engine comprises a metering assembly for providing a variable portion of metered fuel flow to an associated nozzle system. The variable portion corresponds to a variable demand signal received by the metering assembly. A centrifugal pumping assembly is adapted to receive fuel from an associated pumping system. The centrifugal pumping assembly is capable of pressurizing and delivering adequate fuel flow to the metering assembly. A throttling valve is in fluid communication between the metering assembly and the centrifugal pumping assembly to maintain a constant pressure rise across the metering assembly. An electronic engine control provides the variable demand signal to the metering assembly.

摘要： A filter assembly for a fuel delivery system for actuators and fuel control system of an aircraft engine includes a wash flow filter. Fuel flow velocity is increased through the filter through use of a recirculating passage that is effectively achieved through use of an ejector pump. A portion of the pressurized fuel delivered by the main fuel pump is diverted and serves as a motive fluid that scavenges unfiltered flow from downstream of the filter and recirculates or discharges the recirculated flow to an inlet of the filter. This provides increased velocity to maintain sufficient washing of the filter openings.

摘要： A method of increasing the pressure of a fluid in an aircraft centrifugal pump by forcing the fluid to make multiple passes through one impeller of the aircraft centrifugal pump is provided. It includes providing fluid through a pump inlet to an aircraft impeller inlet. The fluid then exits the impeller through a first set of discharge ports and the exiting fluid is directed to a second inlet on the same impeller. The fluid then exits the impeller through a second set of discharge ports to a pump outlet. Each pass through the impeller by the fluid increases the pressure thereof.
