Werkzeug mit einem Sicherheitsventil für Druckfluid

摘要

The valve (12) has a throttle valve (18) moving in a body between a closed position and an open position. A transverse slide (20) displaces the throttle valve to the closed position when fluid pressure is less than a threshold value. The slide has a piston (54) driving the throttle valve to the open position at which the piston contacts the low pressure fluid. A spring drives the throttle valve to the closed position. An Independent claim is also included for a portable drilling machine having a supply circuit including the security valve.
