摘要： An automotive fuel pump having a body with an inlet, an outlet, and an elongated chamber therebetween. A relief valve, relief valve housing, and check valve are respectively disposed in the chamber between the inlet and the outlet. The relief valve housing has a portion which extends across the chamber so that a first axial end of the relief valve housing forms a valve seat for the check valve while the other axial end forms a valve seat for the relief valve. The check valve permits fluid flow from the body chamber to the outlet while the relief valve exhausts excess fluid pressure at the outlet back into the body chamber.

摘要： A hydraulic pump jack cylinder is coupled with a closed loop hydraulic circuit, which includes a hydrostatic pump that delivers hydraulic fluid under pressure to the pump jack cylinder. The pump jack cylinder includes an inner extension piston area and an outer retraction piston area which are configured to have substantially the same area to establish a cylinder ration at 1:1. The hydrostatic pump drives the cylinder rod connected to the oil well sucker rod at a constant velocity in both the extension and retraction strokes with a quick sinusoidal turn-around at the ends of the strokes to provide a change in stroke direction. The swash plate in the hydrostatic pump brake the flow of fluid from the pump jack cylinder during retraction to prevent free-fall. A programmable logic controller controls the swash plate angles to switch stroke direction before the cylinder rod bottoms out.

摘要： A piston pump for a traction-controlled hydraulic vehicle braking system includes a pump piston and an annular piston that is arranged as a second piston in a resiliently loaded manner on the pump piston. As the delivery pressure increases, a resilient element is compressed and a stroke of the second piston is shortened so as to reduce a delivery quantity. This configuration enables a higher delivery pressure to be achieved for a given driving force. With low delivery pressure, the pump piston and the second piston deliver together so as to achieve a rapid build-up of pressure.

摘要： To reduce collision noise created by the operation of an electromagnetic suction valve provided on a high pressure fuel supply pump. In the present invention, in order to achieve the above object, the mass of a member which collides by magnetic attractive force is reduced to reduce the noise to be generated. The thus configured present invention provides the following advantageous effects. The noise generated when a core and an anchor collide with each other by magnetic attractive force depends on the magnitude of the kinetic energy of a moving element. The kinetic energy to be consumed in the collision is only the kinetic energy of the anchor. The kinetic energy of a rod, being absorbed by a spring, does not contribute to the noise; thus, the energy when the anchor and the core collide with each other can be reduced, whereby the noise to be created can be reduced.
摘要翻译：减少设置在高压燃料供给泵上的电磁吸入阀的运转产生的碰撞噪音。在本发明中，为了实现上述目的，减小了与吸引力相撞的部件的质量，以减少产生的噪音。这样构成的本发明提供以下有益效果。当芯和锚通过磁吸引力相互碰撞时产生的噪声取决于移动元件的动能的大小。在碰撞中消耗的动能只是锚的动能。由弹簧吸收的杆的动能对噪声无影响; 因此，可以减少锚和芯彼此碰撞时的能量，从而可以减少要产生的噪声。

摘要： A reciprocating low-speed heavy-load hydraulic pump with a variable action area comprises a plurality of hydraulic cylinder units (3) and moving members (1, 2). Two ends of the hydraulic cylinder units (3) are separately connected with the moving members (1, 2) via mechanical structures. The moving members (1, 2) move relative to each other. The hydraulic cylinder unit (3) consists of a hydraulic cylinder (4), a reversing valve (5) and a one-way valve (6). The hydraulic cylinder (4), the reversing valve (5) and the one-way valve (6) are connected with each other via hydraulic pipelines. Based on different magnitudes of driving force, the hydraulic pump can proactively configure and form different combinations of hydraulic cylinder units, and further adjust the size of an equivalent action area. Therefore, even if the magnitude of the driving force changes, it can be ensured that the hydraulic pump consisting of hydraulic cylinder units outputs oil liquid with a relatively stable pressure for use by a subsequently connected system. The reciprocating low-speed heavy-load hydraulic pump with a variable action area is advantageous in high conversion efficiency, a simple system structure and good working stability.

摘要： A microsystem for converting pressure difference in fluid into mechanical displacement includes input and output nozzles, two interleaved parts, one of which is mobile part, between which the fluid flows. During displacement, the parts define an expanding fluid pocket that moves from the input nozzle to the output nozzle. The micro-system also includes top and bottom planes between which the mobile part is mounted for displacement relative to each plane, an overhanging distal portion along which the fluid flows, and a proximal portion mechanically linked to a plane via a link allowing only longitudinal translation of the proximal portion, and a reinforcement including a first side fastened to one of the planes and, a second side that is either fastened to or in sliding contact with the overhanging distal portion of the mobile part to limit its deformation in a transverse direction perpendicular to the longitudinal direction.

摘要： In open-circuit hydraulic systems (1), the cross-sections of the supply lines (6) and input valves of the hydraulic pump (3) have to be large, so that sufficient flow flux can be provided. This hinders a reduction of the size of the pump and the whole hydraulic system. It is suggested that the supply flow (7) of a hydraulic pump (3) is charged by a second, charging pump (2), to a mid-pressure level (7). The cross-sections of the supply flow areas can thus be decreased.
