摘要： A vehicle oil pump having a first member and a second member relatively rotatable around one axial center such that one of them is inserted in an inner circumferential side of the other, includes: a slider member interposed there between in a direction orthogonal to the one axial center, being relatively immovable in circumferential direction around the one axial center with respect to the first member and slidable in a direction parallel to the one axial center. In the vehicle oil pump, a cam groove is formed in a circumferential surface of the second member facing the first member, a projecting portion is disposed on the slider member being fitted in the cam groove, and the cam groove causes the slider member to reciprocate in the one axial center direction in association with rotation of the slider member relative to the second member around the one axial center.

摘要： A Positive Fluid Displacement Device (PFDD) with a removable Fluid Displacement Module (FDM) having two opposing pistons connected to a drive block. The drive block slides over a crankpin bearing in assembly to provide orbital piston motion. Opposing cylinders are held within a carriage for reciprocating motion. An opening in the reciprocating cylinder head allows fluid communication to the displacement chamber through inlet and outlet ports in a floating port plate. The flat surfaces of the port plate and cylinder head wipe across each other during cylinder head movement. The piston head carries a protrusion sized to fill the cylinder head opening. Micro-adjustment mechanisms for the position of the cylinder head together with compliant piston and compliant cylinder mechanisms can provide near zero dead volume. Different sized opposing cylinders enable the delivery of pumped fluids in precise ratios. By connecting the outlet of each cylinder to the inlet of the opposing cylinder, the differential displacement of the two cylinders can be pumped, enabling the delivery of very small quantities of fluid. High vacuum may be delivered by series connection of cylinders. The device may incorporate a dual lip piston seal which is wear compensated over the life of the seal. The PFDD is leakage free and can be driven by stepper motors to deliver a precise fluid amount at low speed even to an exact portion of a piston stroke. A sensor is provided for sensing cylinder head position.
摘要翻译：具有可移动流体位移模块（FDM）的正向流体位移装置（PFDD），其具有连接到驱动块的两个相对的活塞。驱动块在组合中的曲柄销轴承上滑动以提供轨道活塞运动。相反的气缸被保持在用于往复运动的滑架内。往复式气缸盖中的开口允许通过浮动端口板中的入口和出口流体连通到排量室。端盖板和气缸盖的平面在气缸盖运动期间相互擦拭。活塞头带有一个突起，其大小用于填充气缸盖开口。用于气缸盖位置的柔性调节机构以及符合标准的活塞和顺应气缸机构可提供接近零的死体积。不同尺寸的相对的气缸能够以精确的比例输送泵送的流体。通过将每个气缸的出口连接到相对气缸的入口，可以泵送两个气缸的差异位移，从而能够输送非常少量的流体。高真空可以通过气缸的串联连接传递。该装置可以包括在密封件的使用寿命期间被磨损补偿的双唇活塞密封件。 PFDD无泄漏，可以由步进电机驱动，以低速甚至精确的活塞冲程部分提供精确的流体量。提供一个传感器用于检测气缸盖位置。
