Abstract

An arrangement is disclosed for controlling a pneumatic motor 1, which, for example drives a hoist or lift. The arrangement allows the speed of the motor to be controlled, at a desired valve below the nominal speed. The arrangement includes a motor actuating valve 2 connected between the motor 1 and lines 17 and 3 respectively connected with a compressed air source N and, via a spool controller 4, with an exhaust line 26. The spool of the spool controller 4 has control surfaces 8, 13, 14, 21 so adapted to one another that adjustment of the motor actuating valve 2 causes the pressure difference upstream and downstream of said valve 2 to act via a two-way valve 10 on the spool controller 4 in proportion to the load on the motor 1 so as to throttle to a corresponding extent the exhaust flow from the motor. The motor 1 may have two directions of flow and the load may be effectively applied in both directions. A speed controller R is provided and may act to sense one of the pressures acting on the spool, as shown, when a set speed is reached or the inlet fluid, Figs. 2 & 3, not shown. The spool may be constructed as a differential piston (4', Figs. 2 & 3 not shown). <IMAGE>
