Abstract
A spray gun for spraying fluent materials comprising a valve chamber, a nozzle connected to the chamber at one end thereof, inlet and outlet ports communicating with the valve chamber, and a valve element having a hollow interior displaceable in the chamber between closed and open positions. The valve element is operable in the closed position to extend between the inlet and the outlet ports to allow flow of material through the inlet into the hollow interior of the valve element and out through the outlet. The valve element in the open position is operable to split the flow through the inlet into: a first partial flow through the hollow interior of the valve element and out of the hollow interior and the valve chamber through the outlet; and a second partial flow through the spray nozzle, whereby the flow through the outlet is uninterrupted when the inlet is receiving the material under pressure.
