Abstract
A paint spray apparatus having an airless pump driven by an internal combustion engine, the pump being adapted to provide a continuous paint flow to a spray nozzle or through a relief valve when the nozzle is closed. There is a pressure actuated throttle valve connected to the pump outlet and connected to operate an engine governor or throttle. The throttle valve is set to reduce the engine speed to idling when the spray nozzle is closed, and to reduce the fluid flow through a relief valve which is opened when the nozzle is closed. The throttle valve includes two aligned chambers having an elongated piston extending into both chambers. The pump outlet is connected to one of the chambers in which the outlet pressure acts on the piston to cause it to slide in the chambers and to move the other end of the piston into contact with a governor arm or throttle to effect the slowing of the engine and of the pump to reduce the flow of the fluid out of the pump. The piston is biased in normal operating position out of contact with the throttle by means of two aligned springs in the other of the two chambers.
