Title: Apparatus for draining fluid from a continuously evacuated space

Abstract: Apparatus for permitting drainage of fluids from an evacuated space is disclosed to comprise a casing having a fluid inlet pipe, a drain fitting and a gas by-pass fitting. The fluid inlet pipe extends within a chamber defined by the apparatus body to a point substantially adjacent the bottom of the apparatus body. The drain fitting is displaced upwardly from the bottom of the apparatus body and permits passage of fluids from within the body chamber to a suitable drain connection. The gas by-pass fitting is disposed upwardly of the drain fitting and permits gas to pass inwardly through the drain fitting through the body chamber and out the gas by-pass fitting. The provision of the gas by-pass fitting permits drainage of fluids from an evacuated space to occur through the inlet pipe into the body chamber without being impeded by gas passing from the body chamber upwardly through the inlet pipe and into the space being drained.
