CLOSING DEVICE FOR THE LIQUID DELIVERY LINE OF A HIGH-PRESSURE CLEANING APPARATUS

摘要

Closing device for the liquid delivery line (4, 5) of a high pressure cleaning device comprises a closing body arranged in the delivery line and pressed against a valve seat (7) with a closing force to close the delivery line and removed from the valve seat by an operating element moved by a hand lever (13). A piston (17) movably arranged upstream of the valve seat in the delivery line exits from the delivery line in a sealed manner to interact with the hand lever to support the opening movement of the hand lever. The piston is a cylindrical pin.
