ABSTRACT:
A delay valve comprising a housing including a side wall and opposed end walls and a plug in the housing cooperating with the side wall to define a first and second chamber. A check valve is provided in the plug permitting flow of air in one direction such that air may flow freely from the second through said check valve to the first chamber and is prevented from flowing from the first to the second chamber. The end walls of the housing have openings communicating with the exterior of the housing, and the plug has a peripheral portion that cooperates with the side wall of the housing to define a helical passage communicating with said first and second chambers.
