Abstract
A combination check and relief valve assembly especially designed as a manifold attachment to the exhaust port of a blower and which adapts to the blower's exhaust to maintain pressure within the manifold to a certain range. The combination valve features a manifold having an inner channel which connects to the discharge port of the blower via an inlet port, a check valve assembly having a spring-loaded ball disposed for periodic operative engagement with the inlet port for the prevention of backflow of the fluid discharge and a relief valve assembly mounted in a side channel of the manifold for releasing and venting the fluid discharge through a relief vent port upon an excessive pressure buildup. The relief valve includes a spring-loaded plunger which opens and closes the relief vent port. The combined effect of the two valves helps to maintain the pressure in the manifold to a set adjustable desired range.
