Description: |
| Abstract:
An object of the invention is to provide self-regulating means which, regardless of the fact that a higher than necessary air pressure may be delivered to the device, the pressure will automatically be cut down in the device so that the same operates at some predetermined lower pressure. Another object of the invention is to provide adjustable means for determining the pressure utilized in the device, such as ten, fifteen or twenty pounds, even though the source of air pressure may be very much higher.
Claim:
n a hand spray gun, having a handle for holding the gun, a valve between the supply pressure and its outlet, and means for controlling and regulating the atomizing pressure comprising finger controlled means for opening said valve and pressure actuated means operable by the atomizing pressure for variably closing the valve, said finger controlled means being mounted convenient to the handle so that it can be controlled by the same hand which holds the gun. |
