Abstract
Disclosed is a female-type valve engageable with a male component or instrument, where the valve includes a deformable stem which is located in a valve body and is shiftable therein to receive said instrument in sealed engagement. When an instrument is engaged with an aperture in the stem, the stem shifts in the valve body and the aperture deforms to seal against said instrument and allow liquid to flow through the stem, to or from the instrument. A plug member is carried by the stem, and the plug member can shift to a position of generally sealed engagement with the stem, or it can be displaced by the instrument to permit fluid flow. The plug can reseat upon initial retroactive movement of the instrument, while the instrument is still engaged with the aperture in the stem.
