    • An air motor comprising a piston and cylinder unit and control means mounted wholly within a housing secured to the unit. The housing comprises two parts (11, 12) at the ends of the cylinder (10) and a manifold assembly (28, 30) extending alongside the cylinder (10) and these end parts. The control means comprises a changeover valve (25) in the manifold assembly and two control valves (26, 27) in the respective end parts (11, 12) which are operated by mechanical actuators (K 1, K2) engaged by the piston (13) when it reaches the ends of its stroke and thereupon cause the changeover valve to change over the supply of compressed air from an inlet (60) in the manifold assembly, from one end of the cylinder to the other thereby to reverse the movement of the piston so that the piston reciprocates in the cylinder. The piston may comprise two parts (51, 52) which are adjustable to vary its effective length and hence its strocke.
    • 一种包括活塞和气缸单元的气动马达和完全安装在固定到该单元的壳体内的控制装置。 壳体在气缸(10)的端部处包括两个部分(11,12)和沿气缸(10)和这些端部部分延伸的歧管组件(28,30)。 控制装置包括歧管组件中的转换阀(25)和在各个端部(11,12)中的两个由活塞接合的机械致动器(K 1,K 2)操作的控制阀(26,27) 13)当其到达其行程的端部并且随后使得切换阀从压缩机组件中的入口(60)从气缸的一端到另一端的压缩空气的供给转换时, 活塞使得活塞在气缸中往复运动。 活塞可以包括两个部分(51,52),其可调节以改变其有效长度并因此改变其频率。
