摘要： The present invention provides a heat exchange system for a closed loop fuel delivery system (80). The heat exchange system generally includes a first pump (82), a heat exchanger (84), a high pressure pump (86) and a circulating pump. The first pump pressurizes fuel. The heat exchanger, which is located downstream of the first pump, receives the pressurized fuel flow. The high pressure pump, which is located downstream of the heat exchanger, delivers a predetermined amount of fuel flow to a jet engine. The circulating pump receives fuel flow downstream of the heat exchanger and recirculates the fuel flow upstream of the heat exchanger.

摘要： Vane pump (10) mechanical losses are reduced by removing vane friction losses and replacing them with lower magnitude journal bearing fluid film viscous drag losses. A freely rotating cam ring (70) is supported by a journal bearing (80). A relatively low sliding velocity is imposed between the cam ring and the vanes (26). This permits the use of less expensive and less brittle materials in the pump by allowing the pump to operate at much higher speeds without concern for exceeding vane tip velocity limits.

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 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 fuel delivery system provides closed loop mass flow control between a metering valve (250) and a pump (208). Changes in pressure across the valve are monitored and pump operation is altered in response. A thermal controller (290) monitors fuel temperature and recirculates a portion of fuel through a heat exchanger (202). The system can be provided as original equipment or a retrofit.

摘要： A pumping system for an aircraft engine includes a centrifugal pump and a regenerative start stage that is selectively decoupled from the system upon sufficient pressure being provided by the centrifugal pump. A regulator interposed between the centrifugal pump and the regenerative start stage reduces flow to the start stage in response to increasing output of the centrifugal pump. An ejector removes fuel from the regenerative start stage once the regulator valve is closed, and likewise a check valve is interposed between the outlet of the regenerative start stage and the outlet of the centrifugal pump. This check valve isolates the regenerative pump from the remainder of the system and scavenges or evacuates the fuel from the regenerative pump circuit.

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).
