Negative fluid pressure applied to the interior chamber from the outlet port (when the pump is actuated) causes the diaphragm to flex inwardly and contact the poppet to open the valve. The lockout valve operates like a check valve when subject to reverse flow.

Abstract: An apparatus for producing and maintaining a penile erection in a male suffering from erectile dysfunction includes a resilient ring member defining an inner opening through which the penis is inserted. The inside circumferential surface adjacent the inner opening is supple and adapted to contact the shaft of the penis.
