Abstract

Automatic device for stopping the burner 9 and the electric operating motor 1 of the pump 2 of high-pressure water cleaners, upon closing of the dispensing nozzle 11, able to be applied along the intake line of the pump, which comprises a main line 4 on which are placed valve means 20-23 that are normally open during the operation of the pump, and are able to close under the action of the back flow produced by the closing of the dispensing nozzle 11, in combination with a piston 19 which can travel in a chamber which receives it perfectly tight for a first segment of its travel and free for the next segment of its travel, the piston 19 being maintained in position by a spring 22, and the chamber which receives the piston being placed in communication with the main line 4 respectively upstream from the valve body on the side of the piston 19 that the spring 22 bears against, and downstream from the valve body on the opposite side of the piston, there being also provided a stem 24 axially integrated with the piston 19 which emerges outside to operate the pushbutton of a microswitch 25. <IMAGE>
