Abstract
A valve is provided having a housing with an inlet and an outlet. Within the confines of the housing is a fluid flow path that allows for fluid communication between the inlet and the outlet. The valve includes a valve element that is movable to and from a position where it blocks fluid communication along the fluid flow path, thereby closing the valve. The valve also includes a resilient member provided in a chamber of the valve that is fluidly sealed from the fluid flow path. The resilient member urges the valve element to move to the position for closing the valve. When the pressure of fluid entering the inlet exceeds a preselected amount, the pressure of the fluid overcomes the urging of the resilient member and the valve element moves towards a position that allows fluid communication along the fluid flow path, thereby opening the valve.
