摘要： The piston of a fluid motor divides the cylinder into two variable volumes into which and from which fluid may be selectively introduced and exhausted via ports through the cylinder to relatively move the piston and the cylinder. The piston is modified to define two fixed-volume chambers that respectively communicate with the variable volumes via restrictive orifices. In selected relative piston-cylinder positions, the chambers communicate with the ports to restrict fluid flow into and out of the variable volumes and to decrease the velocity of relative piston-cylinder movement. In other relative piston-cylinder positions, the chambers do not communicate with the ports and fluid enters and leaves the variable volumes directly through the ports to relatively move the piston-cylinder at a higher velocity.

摘要翻译： 流体马达的活塞将气缸分成两个可变容积，流体可从该容积中选择性地引入和排出，通过气缸经由端口排出，以使活塞和气缸相对移动。 活塞被修改为限定两个固定容积的室，其分别通过限制孔与可变容积连通。 在选定的相对活塞 - 气缸位置，腔室与端口连通，以限制流体流入和流出可变体积，并降低相对活塞 - 气缸运动的速度。 在其他相对的活塞 - 气缸位置，室不与端口连通，并且流体进入并且通过端口直接离开可变容积以相对地以更高的速度移动活塞 - 气缸。
