Abstract
A solenoid valve, whose valve member is acted upon by a feed pressure in a closed setting by the feed pressure obtaining in an inlet duct. In order to render possible rapid switching operations a moving ancillary drive member is provided which is acted upon by a control pressure and which acts through an outlet duct in the opening direction, and hence against the feed pressure, on the valve member.
