ABSTRACT:
A spring (304) biases a movable housing part (12, 16) away from a fixed housing part (10, 306, 156). The fixed housing part (10, 306, 156) is composed only a main housing (10), a draw tube (306) and an inlet valve housing (156). The inlet valve housing (156) is inserted into the main housing (10). The movable housing part (12, 16) is composed of a forward housing (12), which includes a trigger (14), and a nozzle (16). The main housing (10), the inlet valve housing (156) and the forward housing (12) together form a variable volume pump chamber (318). The inlet valve (184, 268) includes , a valve plug (184) which is initially connected to a sidewall portion (168) of the inlet valve housing (156) by a frangible section (196). During assembly, an axial push is imposed on the valve plug (184), to sever the frangible section (196), and then move the valve plug (184) rearwardly past stop lugs (198, 200), into a position axially between the stop lugs (198, 200) and an inlet valve seat (268). The nozzle (16) is rotatable between an "open" position in which two sections (64, 97) of an outlet passageway are in alignment, to permit liquid flow from the pump chamber (318) to an outlet opening (46) and a "closed" position in which the two passageway sections (64, 97) are out of alignment, and flow out from the pump chamber (318) is blocked.
