Abstract
A valve which is particularly adapted for use as a backflow safety valve for therapy pools, in which it prevents water from flowing through the air supply line and damaging the air blower. When the water outlets of the therapy pool are temporarily blocked, water which is forced into the air supply line by water pressure flows into the open end of a cup shaped valve member and moves it to closed position within the air supply line. The safety valve will automatically re-open when the blockage is removed.
