摘要： An eccentric-driven piston pump for a vehicle controlled braking system has a pump drive apparatus including a stub shaft having an eccentric journalled in a pump housing for self-supported rotation about a stub shaft axis by a first and a second rotating bearing disposed on opposite axial sides of the eccentric. The stub-shaft is operatively connected to the rotating drive shaft of a motor, and the eccentric is connected for imparting reciprocating motion to the pistons. A pair of thrust bearings including a counterweight for balancing the pump drive apparatus, are disposed on the stub shaft adjacent the eccentric at opposite axial ends thereof between the eccentric and first and second rotating bearings. The motor includes a spherical bearing for alignment of a motor drive shaft with the stub shaft, and a bushing for loosely supporting the drive shaft prior to attaching the drive shaft to the stub shaft.

摘要： A piston pump (20), in particular a high-pressure pump for a fuel system of an internal combustion engine, includes a housing (72). In addition, a piston (94) is provided, which defines a working chamber 100. A drive shaft (78) is supported in the housing (72) by means of at least one shaft bearing and has at least one crank section (86). A piston bearing supports the piston (94) at least indirectly against the crank section (86) of the drive shaft (78). At least one of the bearings between parts that move in relation to one another is a hydrostatic bearing (62). This hydrostatic bearing is connected to the working chamber (100) by means of a fluid connection. In order to increase the efficiency of the piston pump (20), the invention proposes that the fluid connection between the working chamber (100) and the hydrostatic bearing (62) be provided with a device (56; 118) that can intermittently interrupt the fluid connection.

摘要： A variable delivery fuel supply device capable of improving linearity of discharge characteristics with respect to a rotational angle of a cam and reducing abrasion of the cam. The variable delivery fuel supply device comprises: fuel injection valves 1a to 1d respectively for injecting a fuel to cylinders of an internal combustion engine; a delivery pipe 2 for supplying a pressurized fuel to said fuel injection valves 1a to 1d; and a fuel pump 3 for taking a fuel from a fuel intake passage 24 through an intake valve 25 into a pressurization chamber 17 during an intake stroke, for pressurizing the fuel and for discharging the pressurized fuel through a discharge valve 26 to the delivery pipe 2 during a discharge stroke by reciprocating movement of a plunger 14 in each cylinder 13 from a bottom dead point to a top dead point; wherein the pressure in the pressurization chamber 17 is relieved at a position set to a predetermined value before reaching the top dead point in the course of the discharge stroke in which the plunger 14 of the fuel pump 3 moves from the bottom dead point to the top dead point.

摘要： A vibration reducing shoe for biasing a cam ring of a variable displacement ball pump into engagement with a surface of the pump housing. In a hydrostatic transmission having a variable displacement pump and a fixed displacement motor a pair of shoes are located within bores in the pintle. The shoes are slidably received in the bores and exert a force against the cam ring which is proportional to the pressure of the fluid used to rotate the motor. Since the pump is reversible, one shoe is in fluid communication with one of the passages directing fluid to the motor and the other shoe is in fluid communication with the other passage. Accordingly, the force exerted on the cam ring by the shoes increases and decreases with increases and decreases in the pressure of the fluid from the pump to the motor.
摘要翻译：一种用于将可变排量球泵的凸轮环偏置成与泵壳体的表面接合的减振鞋。在具有可变排量泵和固定排量电动机的静液传动装置中，一对鞋位于枢轴中的孔内。鞋可滑动地容纳在孔中并且对凸轮环施加力，其与用于旋转马达的流体的压力成比例。由于泵是可逆的，所以一个鞋与将流体引导到马达的一个通道流体连通，另一个鞋与另一个通道流体连通。因此，通过鞋的作用在凸轮环上的力随着流体从泵到马达的压力的增加和减小而增加和减小。
