Abstract
An elastomer diaphragm is mounted in a housing so as to be manually deflectable to open a valve mechanism and permit liquid flow in either direction through the housing between a pressurized reservoir and an implanted penile erection device. When pressure is removed, the diaphragm recovers to an original position and closes the valve mechanism with an inherent spring force. In a flaccid state, the valve mechanism also is retained closed by high liquid pressure on the reservoir side thereof. A push button on the diaphragm projects outward to make it easy to find under the skin of the user. The diaphragm is formed with integral seals, and is maintained in a compressed state to facilitate sealing of the liquid in the housing and to enhance the self-sealing capability of the diaphragm when penetrated by a needle.
