摘要： A durable, single action, variable displacement vane pump capable of undervane pumping, components thereof, and pressure balancing method. The pump comprises a cylindrical barstock rotor member having large diameter journal ends and central vane slots uniformly spaced therearound. The vane slots are elongate and have a central vane-supporting portion of maximum depth surrounded at each end by extension portions having depths which decrease axially to the surface of rotor member. The vaned rotor is rotatably supported within a unitary cam member having opposed faces and a circular bore therethrough forming a cam chamber having a continuous interior circular cam surface. The cam member is pivotably supported relative to the rotor to adjust the displacement capacity of the pump by means of a fluid pressure-powered adjustment system. The vane slot extensions in the rotor project outwardly beyond the cam chamber. An opposed pair of manifold bearings rotatably support the journal ends of the rotor and overlap the vane slot extensions to admit fluid to expanding vane bucket areas of the rotating vaned rotor and also into the vane slot extensions and undervane areas for pressure balancing purposes. The vane slot extensions also permit discharge of pressurized fluid from contracting vane bucket areas, and from undervane areas as the vanes are depressed into the vane slots, to increase the displacement capacity of the pump. Fluid passages and pressures within the pump are arranged to balance forces acting on various parts to reduce stress, improve sealing, and permit sharing of a fluid pressure source.
摘要翻译：一种耐用，单作用，能够进行底抽泵的可变排量叶片泵，其部件和压力平衡方法。泵包括具有大直径轴颈端部和在其周围均匀间隔开的中心叶片槽的圆柱形棒料转子件。叶片槽是细长的，并且具有最大深度的中心叶片支撑部分，每个端部具有通过延伸部分的延伸部分，其深度与转子构件的表面轴向减小。叶片转子可旋转地支撑在具有相对面的一体式凸轮构件中，并且圆形孔穿过其形成具有连续内部圆形凸轮表面的凸轮室。凸轮构件相对于转子枢转地支撑，以通过流体压力调节系统调节泵的排量。转子中的叶片槽延伸部向外突出超出凸轮室。相对的一对歧管轴承可旋转地支撑转子的轴颈端并与叶片槽延伸部重叠，以将流体接纳到旋转的叶片转子的扩展叶片桶区域，并且还可以进入叶片槽延伸部和底座区域以用于压力平衡目的。叶片槽延伸部还允许压缩流体从收缩叶片桶区域排出，并且当叶片被压入叶片槽口时从底盘区域排出，以增加泵的排量。泵内的流体通道和压力被布置成平衡作用在各个部件上的力以减少应力，改善密封并允许流体压力源共享。

摘要： A variable-displacement vane pump apparatus is composed of a pump part and a switching valve. The pump part is comprised of a housing, a cam ring, a rotor, plural vanes, side plates, two pairs of intake and exhaust ports formed on the side plates, discharge pressure chambers connecting with the discharge ports, and an intake chamber connected with the intake ports. The pump part is divided into first and second pump portions, and only one of the pump portions is activated by the operation of the switching valve when the load pressure is low. Under such condition, the fluid discharged from the particular pump portion is returned to its intake port. Also, the flow rate of the operation fluid discharged from the pump is adjusted by the flow control valve by returning part of pressurized fluid into the inlet ports. A fluid supplied from a reservoir is energized two times by supercharge effect utilizing the returned fluid from the switching valve and the returned fluid from the flow control valve. The vane pump is further provided with a special arrangement to lower the pressure at the bottoms of slits receiving the vanes at the time period when the slits located in the particular pump portion, thereby reducing the energy loss.

摘要： A fluid pressure energy translating device (10) of the sliding vane type comprising a cam ring (13) including an internal contour (30), a rotor (25) having a plurality of vanes (36) rotatable therewith and slidable relative thereto in slots in the rotor (25) with one end of each vane (36) engaging the internal contour (30). The rotor (25) and internal contour (30) cooperate to define one or more pumping chambers (31, 32) between the periphery of the rotor and the cam contour through which the vanes (36) pass carrying fluid from an inlet port (19) to an outlet port (22). At least one cheek plate (16, 17) is associated with the body (11) and rotor (25). Two pressure chambers (39, 40) are formed for each vane (36) and each vane has two piston surfaces, one in each chamber, both being effective under pressure in the respective chambers (39, 40) to urge the vanes into engagement with the cam (13). A generally annular internal feed passage (44) is formed entirely within the rotor (25) and communicates with one set (39) of the pressure chambers. A radial passage (41) is provided on each vane (36) extending from the tip of the base thereof, so that cyclically changing pressure is supplied to the other set (40) of chambers. Arcuate grooves (49a, b) are provided in the face of the cheek plate (16, 17) in the dwell zones, and a hydrostatic pressure pad (48) is associated with the opposite face of the cheek plate (16, 17) and circumscribes the arcuate grooves (49a, b). An opening (50) extends from the arcuate grooves (49a, b) through the cheek plate (16,17) to the hydrostatic area (48).

摘要： A pump device includes: a main pump (101) and a sub pump (102) that supply hydraulic oil to the hydraulic device (23); and a switching valve (40) that switches so as to supply the hydraulic oil discharged from the sub pump (102) to the hydraulic device (23), or to return the hydraulic oil discharged from the sub pump (102) to the suction side. The main pump (101) and the sub pump (102) each include: a rotor (2) connected to a common drive shaft (1), a discharge port (9) into which the hydraulic oil discharged from a pump chamber (7) is led, and a groove-shaped discharge-side notch formed from an opening edge of the discharge port (9) toward a direction opposite to a rotation direction of the rotor (2). The switching valve (40) switches according to a rotation speed of the drive shaft (1). At least one discharge-side notch (9b) of the sub pump (102) is formed so that a resistance applied to the flow of the hydraulic oil passing therethrough is greater than that of the discharge-side notch (9b) of the main pump (101).

摘要： A rotary vane compressor includes a cylinder chamber having an ellipsoidal inner wall shape, a rotor rotatably provided in the cylinder chamber, a vane held in the rotor so as to contact with an inner wall surface of the cylinder chamber along with a rotation of the rotor, a vane slot provided on the rotor and offset on a reverse rotational side of the rotor from a radial line passing over a rotational center of the rotor, and a controller for controlling a rotation of the rotor. The controller reversely rotates the rotor for a predetermined time upon activating the compressor. According to the compressor, chattering can be prevented by surely protruding the vane from the vane slot without providing extra parts. In addition, the vane can be produced with easy working processes at low cost.
