ABSTRACT:
An improved air valve assembly for mounting in a prosthesis, such as an artificial leg, and a spanner-type tool for mounting and removing the valve assembly. The valve assembly includes a housing to be mounted in the prosthesis with gaskets located on each side and secured therein by a removable retaining collar, a valve body removably mounted in the housing, and a spring-biased valve release stem mounted in the valve body, with seals positioned about the valve body and about the release stem. The spanner-type tool includes a spanner having protruding pins which are adapted to extend into holes in the valve housing and a threaded central opening into which is threaded a screw shaft which is adapted to extend through the valve housing, the screw shaft extending through a central opening in a tool body and handle and secured to a knob, and with a retainer ring mounted in a groove in the screw shaft and located intermediate the spanner and the tool body. The tool enables the valve housing to be held against the prosthesis, without rotation therein, while the retaining collar is being tightened so as to provide a firm installation of the valve housing and gaskets in the prosthesis.
