Abstract
An adjustable air pressure valve for placement in a compressed air hose. Positioning a knob determines the pressure exerted by a spring on a valve member which allows air above a predetermined pressure to escape from the hose to the atmosphere. The knob is incrementally moveable to provide incremental pressure changes.
