ABSTRACT:
A check valve is provided comprising a cap having an inlet port and a body with an internal recess whose periphery is engaged with the cap and contains an outlet port. A rib extends across the body recess and is supported and urged against the cap by the rib substantially along the entire length of the rib. The diaphragm is engaged against the cap to close the valve, with the peripheral edges of the diaphragm being adapted to bend away from the cap to open the valve when a predetermined fluid pressure is exerted at the inlet port.
