ABSTRACT:
The solenoid valve actuates a pilot valve body which cooperates with a stationary seat surface. The pilot valve body actuates a main valve body of an on-off valve having a piston with a calibrated leakage. The cylindrical chamber on one side of the piston communicates with the inflow side of the on-off valve when the solenoid valve is opened via the pilot valve body, and the cylinder chamber on the other side of the piston communicates directly with a discharge. That side of the piston which is near the main valve body is isolated from the flow path of the on-off valve. The possibility of leakage is reduced considerably for a very reduced constructional outlay, electricity consumption is low and the loss of valve-time cross-section associated with an opening instruction is reduced.
