SPRAY GUN WITH FLUID VALVE.

摘要

A spray gun having a fluid flow control valve which is preferably located in a spray head. The flow control valve eliminates the need to change the spray head or fluid tip to change the flow rate in a suction feed and/or gravity feed paint spray gun when different materials are sprayed. The valve has a member which is rotatable over no greater than 360 degree and preferably over about 90 degree for adjusting the flow rate. Calibration marks may be provided for setting the valve for flow rates produced by standard fluid discharge orifice sizes.
