Abstract

A pneumatically driven, reversible motor (1), for example, for a hoisting implement, comprising ports connected with two supply ducts for the forward and return run respectively, the feed being controlled by means of a pneumatic control-circuit, wherein at least one feed duct includes a proportionally operat­ ing reducing valve (2), which is controlled by means of a con­ trol-duct (3) with a manually actuated, proportionally operating reducing valve (5, 6, 5′) raising the pressure to the pneumatic motor (1) such that the moment produced by the load can just not be retained by the motor (1), where upon the motor will ro­ tate with low speed in the opposite sense, said low speed be­ ing controlled by the extent of opening of the reducing valve.
