Abstract

A pressure control valve includes an upper body, a lower body affixed to the upper body, a supply passage in the upper body, a delivery passage in the upper body, an exhaust passage in the lower body and a pivotable member positioned between the supply passage and the delivery passage. The pivotable member has a generally curved body, a first leg, a second leg and a third leg extending from the body. The pivotable member pivots on the second leg and the third leg in response to air pressure in the supply passage being less than the air pressure in the delivery passage. The positioning of the pivotable member restricts air from flowing from the delivery passage to the supply passage, thereby opening a path for the air to pass to the exhaust passage.
