The knob is incrementally moveable to provide incremental pressure changes.
Claims5
An adjustable air pressure valve for insertion in an air hose comprising a housing, a fitting in said housing including inlet means and outlet means for connecting said valve in the air hose, a valve seat formed on said fitting, said fitting having a passage interconnecting said inlet means, said outlet means and said valve seat, a valve member engaging said valve seat, means in said housing for exerting an adjustable pressure on said valve member to establish the maximum air pressure in the air hose, and wherein said adjustable pressure exerting means includes a valve actuator having a first end secured to said housing and having a free second end, said actuator having a resilient section adjacent said first end, a spring positioned between said actuator and said valve member, and means for pivoting said actuator about said resilient section to adjust the force exerted by said spring on said valve member.
