摘要： In a pump housing of a pump apparatus, a pump shaft is rotatably supported by two bearings and is connected to a pump unit. A rotary drive member is fixed to one end of the pump shaft projecting from the tip end portion of the housing. The rotary drive member includes a boss portion fixed to the one end of the pump shaft projecting from the housing, and a rim portion integral with the boss portion. The rim portion is offset from the boss portion to cover at least a portion of the tip end portion of the housing. A groove portion for receiving a drive belt is formed on the outer circumference of the rim portion. The widthwise center plane of the groove portion is located between the respective centers of the two bearings. In place of the groove portion, a tooth portion engageable with a drive gear may be formed on the outer circumference of the rim portion. Preferably, the pump unit is of a balanced vane type.

摘要： This invention concerns pumping fluids to both high pressures and high flow rates and thus has a very high power density. The technology pertains to both fluid power and to fluid transfer and is adaptable to a wide scope of use. The concept is a very simple rotary variable displacement expansible chamber pump which can also be a rotary kinetic pump and thus is a hybrid. At a positive displacement setting, the pump primes by positive displacement, then as the rotational speed increases; the pump gains a kinetic pumping component, then as head pressure increases the pump again becomes positive displacement. At a zero displacement setting, the pump is purely a rotary kinetic pump. The variable displacement feature allows both performance and efficiency. The porting allows very high rotational speeds and flow rates near to centrifugal designs. When set at zero displacement, the device has features both of positive displacement fan (gear pump) and kinetic (centrifugal pump). The pump is vibration free and silent. Fields of use are fluid power, where the power density is higher, and fluid transfer where high flow rates at higher pressures are required. The concept marries rotary positive displacement to rotary kinetic in pumps.

摘要： The invention relates to a roller vane pump for operating an automatic transmission for motor vehicles. The pump is provided with a pump housing (12), a rotor (4), a cam ring (2) and roller elements (7), which define a number of pump chambers (13). Fluid is communicated between a hydraulic channel (24) and a pump chamber (13) through suction ports (11 and 16) and discharge ports (17 and 18). According to the invention the pump is provided with a suction port (26) for allowing a predominantly radial flow of fluid to a pump chamber (13) and/or with a rotor (4) with slots (6) with a circumference (32) which is partly curved with a curvature substantially matching the curvature of the roller elements (7) and/or with a rotor (4) with a circumference segment (30) deviating at least partly from a circle, in order to decrease the amount of wear of pump parts as well as the noise level generated during pumping.

摘要： In the back pressure groove structure of a variable displacement vane pump comprising a rotor rotatably contained in a pump housing and having a plurality of vane grooves arranged radially and equidistantly in a circumferential direction, a cam ring is arranged in the pump housing in a movable and displaceable manner, fitted into the pump housing to form a pump chamber with an outer peripheral portion of the rotor and applied with an urging force to provide a maximum volume of the pump chamber. A side plate is contained in the pump housing in a non-rotatable manner, slidably contacting with one sides of the rotor and the cam ring and having back pressure grooves communicating with the vane grooves. A cover plate closes an opening of the pump housing, slidably contacting with other sides of the rotor and the cam ring and having a back pressure groove communicating with the vane grooves, the back pressure grooves of the side plate communicate with a high pressure side and are divided back pressure grooves obtained by dividing an annular back pressure groove into a pump suction side groove and a pump discharge side groove. The back pressure groove of the cover plate is an annular back pressure groove or a C-shaped back pressure groove obtained by closing the annular back pressure groove at one of a pump suction side portion and a pump discharge side portion into which the annular back pressure groove is virtually partitioned.
