摘要： Variable displacement pump has first control hydraulic chamber 21 giving force to cam ring 5 in direction that decreases volume variation of each pump chamber 13 by internal pressure, second control hydraulic chamber 22 giving force to cam ring in direction that increases volume variation of each pump chamber by internal pressure, first seal surface 44 formed on both end surfaces of cam ring, which are in sliding-contact with both opposing inside surfaces of pump body 1 and cover member 2, and sealing gap between each pump chamber and first control hydraulic chamber, and second seal surface 45 sealing gap between each pump chamber and second control hydraulic chamber at outlet section side. Radial direction width W2 of second seal surface is greater than that W1 of first seal surface. Increase in weight of the pump can be suppressed while suppressing increase in pump control pressure against intention of control.

摘要： The invention relates to a method for operating an internal combustion engine, wherein in an oil circuit (14) of the internal combustion engine, in particular for forced-feed lubrication, a first oil pressure stage having a first minimum and maximum oil pressure level and at least one second oil pressure stage having a second minimum and maximum oil pressure level are alternatively produced by an oil pump (12), wherein the first minimum oil pressure level is less than or equal to the second minimum oil pressure level and the first maximum oil pressure level is less than the second maximum oil pressure level, wherein a camshaft (16) of the internal combustion engine is hydraulically adjusted by an actuator (18) by means of an oil pressure from the oil circuit (14) of the internal combustion engine. During the adjustment, a first adjustment speed of the camshaft (16) is set by the actuator (18) while the first oil pressure stage is produced by the oil pump (12), wherein a second adjustment speed of the camshaft (16) is set by the actuator (18) for at least one second oil pressure stage while the second oil pressure stage is produced by the oil pump (12), wherein at least one difference between the first and at least one second adjustment speed is determined, wherein a switching mechanism (20) of the oil pump (12) for switching between the oil pressure stages is classified as being in order if a magnitude of the difference is greater than or equal to a predetermined difference value, and the switching mechanism (20) of the oil pump (12) for switching between the oil pressure stages is classified as defective if a magnitude of the difference is less than a predetermined difference value.

摘要： A variable displacement vane pump includes at least two regulation chambers to provide a regulating force to the cam ring, to counter the force applied to the cam ring by a regulating spring, to reduce pulsation in the output working fluid from the pump. A first one of the chambers is part of the pump outlet and is in fluid communication with the outlet port of the pump via a passage which allows the pump to be fabricated from a diecast process oath like. A second regulation chamber is connected to the first chamber via an orifice which reduces the pressure of working fluid supplied from the first chamber to the second. The configuration and design of pumps in accordance with the present invention allows for flexible packaging for the pump, as the outlet need not overlie the pump outlet. Further, a pump with an inlet port with a relatively large initial cross-sectional flow area is taught to inhibit cavitation of the working fluid when the pump is operated at higher operating speeds.

摘要： A method of operating a fuel system to determine the extent of internal wear of a fuel pump (16, 46) thereof comprises driving the fuel pump (16, 46), moving a metering valve member (24) to a closed position in which it bears against a resilient stop (56), increasing the operating speed of the fuel pump (16, 46) to increase the pressure applied to the metering valve member (24) urging it towards the resilient stop (56) to a point beyond which further movement of the metering valve member (24) occurs, sensing when the further movement of the metering valve member (24) occurs, and sensing the operating speed of the pump (16, 46) at the time when said further movement occurs.

摘要： The invention relates to a roller vane pump suitable for pumping transmission fluid in an automatic transmission for motor vehicles. The pump is provided with a pump housing (2), a rotatable carrier (3) being located in the interior of the pump housing (2), a cam ring (5) surrounding the carrier (3) in radial direction, and roller elements (7) being provided in slots (6) in the carrier periphery. The spaces between the pump housing (2), the carrier (3), the cam ring (5) and the roller elements (7) define a number of pump chambers (8). Furthermore, the pump is provided with feed apertures (9) for allowing a flow of fluid to a pump chamber (8) and with discharge apertures (10) for allowing a flow of fluid from a pump chamber (8). According to the invention constructional measurements are taken to avoid the occurrence of cavitation and to obtain higher pump efficiency.

摘要： A pump having unloading means associated therewith repetitively unloading same. The pump may be of the rotary positive displacement type with the unloading means taking the form of circumferentially extending pressure relief recesses (120) located along an edge of the rotor cylindrical portion (103) intermediate lobes (113 and 114). Communication between the pump inlet (101) and outlet (102) occurs repetitively producing a pulsating output. In use of the pump in a drive transmission system transmitting power from a prime mover to a load, a flywheel driven by the prime mover drives the pump which in turn drives an hydraulic motor. The unloading means repetitively unloads the pump allowing the prime mover to accelerate the flywheel, compensation means being provided to drive the hydraulic motor while the pump is unloaded. Other kinds of pumps provided with means internal or external thereto for repetitively unloading same, are also disclosed.

摘要： A fluid device (1) relating to the present invention includes a first housing (45) having first flow channels (111 to 114), a second housing (2, 3, 33 and 35) having second flow channels (41 and 42) that are larger in number than the first flow channels (111 to 114), and a distributor plate (100) having a third flow channel connecting together a predetermined one of the first flow channels (111 to 114) and corresponding ones of the second flow channels (41 and 42). The distributor plate (100) is sandwiched between the first housing (45) and the second housing (2, 3, 33, 35) in a thickness direction of the distributor plate (100) such that end surfaces (101 and 102) of the distributor plate (100) are in contact respectively with the first and second housings (45 and 2, 3, 33, 35). The third flow channel (103 to 107) includes: a plurality of through flow channels (103) that are arranged next to each other in a circumferential direction and open at the end surfaces (101 and 102); and one or more connecting groove flow channels (104 and 105) extending in the circumferential direction and connecting together the through flow channels (103).
