[Also in Division G3] A device for controlling the operation of a compressor, Fig. 1 (not shown), comprises a housing (1) in which a piston valve (5) is movable off its seating (6) against the action of a spring (9) by a predetermined reservoir pressure supplied through a connection (4), whereby air passes to bores (16, 18) connected respectively to a working cylinder controlling the speed of the compressor motor and via a bore (17) to a working cylinder controlling the compressor suction valve. A piston check valve (19) having a resilient packing (23) and an orifice (25) opens when air is supplied to the bore (18). When the pressure in the reservoir falls the valve (5) closes and air escapes from the bore (16) to atmosphere past a valve seating (7), whereas air in the bore (17) slowly escapes to atmosphere through the orifice (25) ensuring that operation of the suction valve lags the operation of the motor.
