Abstract

The device comprises a piston (17) sensitive to the pressure difference between the upstream and downstream side of the valving element for the pressurized water flow to the delivery lance. Said piston (17) is connected, in series therewith, into a low voltage electrical circuit which is closed and respectively opened by the movements of said piston, said movements bringing it into contact with, and respectively withdrawing it from, an electrode (19), an electronic circuit (260) being provided which, in response to contact between the piston (17) and the electrode (19) energizes an electrical switch to open the power circuit of the jet washer electric motor. <IMAGE>
