Control valve for double-acting pneumatic working cylinders

摘要

A control valve for double-acting pneumatic working cylinders, with at least one feed-air inlet, controlled air outlets in each case connected to the pressure spaces of the double-acting working cylinder, and also a vent outlet and a housing, has already been proposed, in which a spool displaceable in the axial direction by actuation of a solenoid valve allocated to it has been arranged. For the purposes of the further development according to the invention, the spool is designed as a differential spool (D) which is provided with two parts movable in the axial direction, and the movable parts are allocated to one another by an elastic means. <IMAGE>
