ABSTRACT:
A safety valve which interrupts fluid flow when it is substantially tilted or inverted, comprises a valve chamber with three lobes two of which have an inlet and an outlet opening at an inlet and an outlet valve seat, respectively. A ball is freely movable within the chamber. When the chamber is in its normal position, or preferred orientation, the ball rests or floats in the third lobe, but when the chamber is tilted or inverted, the ball moves into one of the other lobes and abuts against the inlet or the outlet valve seat.
