ABSTRACT:
A solenoid valve unit for the control of the supply of compressed air to an air driven load and controlling the letting off of such air from the load has a valve housing with a pressure port, a power air port, a let off port for the valve space and a further let off port for the load driven by compressed air. The further pressure let off port is opened up and shut off by a valve plate or thimble that is only moved by pressure. This design makes possible a compact form of the valve so that the pressure port, the power air port and the further pressure let off port are placed on only two housing faces.
