    • A pneumatic motor having a plurality of cylinders, with each cylinder having an expansion chamber (15), defined in part by a piston plate (2); and a diversion chamber (16) which is divided into two chambers by a slide plate (11), with the diversion chambers connected to a pressure supply line (27) and to a pressure diversion line (28). The piston plate is connected to a piston rod (5) by a lock (3). The expansion chamber holds an amount of compressed air held constant throughout the operation cycle. Expansion of the expansion chamber moves the piston plate and piston rod (5) to rotate a crankshaft (5a). At the end of the expansion stroke, the piston rod is disconnected from the piston plate. The expansion chamber is compressed by pressurizing the diversion chamber below the slide plate (11), forcing the slide plate and push rods (7) upwards, which pushes the piston plate upwards, until the piston plate can be held at a top position by a lock (3'). The diversion chamber below the slide plate is pressurized by pressurized air from diversion chambers of cylinders in which the expansion chamber has been compressed, along with supplemental air from a compressor (30).
    • 一种具有多个气缸的气动马达,每个气缸具有由活塞板(2)部分限定的膨胀室(15)。 和分配室(16),其通过滑板(11)分成两个室,分流室连接到压力供应管线(27)和分流管线(28)。 活塞板通过锁(3)连接到活塞杆(5)。 膨胀室保持在整个操作循环中保持恒定的一定量的压缩空气。 膨胀室的膨胀使活塞板和活塞杆(5)移动以使曲轴(5a)旋转。 在膨胀行程结束时,活塞杆与活塞板断开。 通过对滑板(11)下方的转向室进行加压来压缩膨胀室,迫使滑板和推杆(7)向上,将活塞板向上推动,直到活塞板能够保持在顶部位置 锁(3')。 滑动板下方的转向室由压缩机(30)的补充空气与加压空气一起被加压,该压缩空气来自膨胀室已被压缩的气缸的转向室。
