ABSTRACT:
A high pressure water gun for washing electrical insulators and other related articles, which gun has a barrel, a water inlet, a water outlet (nozzle), a pistol grip and a main body portion, which portion communicates with both the inlet and with a lower valve chamber separated from an upper piston chamber. A piston is vertically slidably mounted in the upper chamber. A check valve is slidably mounted horizontally in the lower chamber and is spring biased, when the gun is in the inoperative position. A port extends between the lower chamber and communicates with the upper chamber. Another port in the lower chamber communicates with the barrel. Water introduced into the inlet follows a dual path and ejects out of the nozzle with relatively little pull required on the trigger.
