摘要： A double-acting reciprocating motor with uni-directional fluid flow path comprises a piston disposed within a cylinder. A first chamber is defined by the cylinder space between the piston and a cylinder base. A second chamber is defined by the cylinder space between the piston and a cylinder head. Fluid is introduced into the motor through an inlet port and into the first chamber. A pass-through valve controls the flow of fluid from the first chamber to the second chamber. An outlet valve regulates the draining of fluid from the second chamber through an outlet port. The outlet port and the inlet port are associated with opposite ends of the motor. Differential fluid pressure urges the piston towards the cylinder head when the pass-through valve is closed and the outlet valve is open. The piston surface facing the second chamber is larger than the piston surface facing the first chamber, so the piston moves towards the cylinder base when the pass-through valve is open and the outlet valve is closed.
摘要翻译：本发明涉及一种具有单向液流回路的双向作用的往复式马达，包括布置在缸体中的活塞。第一腔室由活塞和圆柱形底座之间的圆柱形空间限定。第二个腔室由活塞和圆柱形头部之间的圆柱形空间限定。液体通过进料口进入发动机并进入第一室。锁定阀控制液体从第一室流向第二室。供应阀调节从第二室通过出口端口的液体排放。出口端口和供应端口与发动机的相对端相关联。当气锁阀关闭且供气阀打开时，差压液压将活塞推向圆柱头。面向第二腔室的活塞表面大于面向第一腔室的活塞表面，使得当锁定阀打开且供给阀关闭时，活塞朝向圆柱形基座移动。

摘要： A hydraulic machine comprising the following: an envelope (2); a differential piston (15) consisting of two parts (15a,15b) which have a different diameter and are able to move in two corresponding chambers (7,6); hydraulic switching means which are driven by the piston (15) and can take up two stable positions in relation to the piston; control means for a rapid change in the position of the switching means including elastic means (E); and releasing means that can release the energy accumulated by the elastic means at the end of the travel and result in an abrupt change in the position of the switching means. The switching means are supported by a side-walled (27) lantern ring (26) that is coaxial to the piston and is driven by the piston but which can take up two different stable positions in relation to the piston and elastic means (E) are disposed inside the lantern ring (26) and are internally guided by the side wall (27) of said lantern ring (26).
摘要翻译：一种液压机，包括以下装置：一个信封（2）; 由两部分（15a，15b）组成的差动活塞（15），它们具有不同的直径并且能够在两个相应的腔室（7,6）中移动; 液压切换装置，由活塞（15）驱动并能相对于活塞承受两个稳定的位置; 用于快速改变包括弹性装置（E）的切换装置的位置的控制装置; 以及释放装置，其能够在行程结束时释放由弹性装置积聚的能量，并导致开关装置的位置的突然变化。切换装置由与活塞同轴并由活塞驱动但可相对于活塞和弹性装置（E）占据两个不同稳定位置的侧壁（27）的灯笼环（26）支撑，设置在灯笼环26内，由所述灯笼环26的侧壁27内部引导。
