ABSTRACT:
In fluid jet transfer valves comprising two opposing jet tube openings with high pressure fluid flowing out of one opening towards the other, the end surfaces of the jet tubes are provided with a novel shape which allows the tube ends to seal tightly together when they are coaxially aligned with each other and also to be deflected apart without binding. The shape of the end surface on one of the tubes is an inverted reproduction of the surface on the opposing tube so that when the tubes are coaxially aligned with each other and pressed together a tight seal will be formed. The end surfaces on the tubes are shaped so that the tubes may be freely moved laterally relative to each other without binding. The tilt of the end surfaces of the two tubes is minimized so that small lateral closure forces will generate much larger axial seating forces and so that the lateral opening forces created by escaping high pressure fluid are minimized.
