ABSTRACT:
A handle mounted adjacent one end of a centrally bored body when squeezed toward the body turns a stem through about 22.degree.. The interior of the stem is cut away so that all that remains is a 90.degree. sector which functions as a cam. On the opposite end of the body is an inlet port. A reciprocable actuator has a seat at one end which is biased to close the inlet port. The opposite end of the actuator engages the cam. Vanes on the actuator center the actuator relative to the bore of the body and permit fluid to pass from the port past the stem when the handle is depressed. When the handle is up, the cam is positioned so that the end of the actuator moves forward by spring and water pressure force to close the valve. When the handle is depressed, the cam turns to force the stem back to unseat the valve and because the stem is cut away for approximately 270.degree., fluid flows around the stem and out of the discharge port.
