Patent ID: 8734596

Claim:
A siphon adapted for thoroughly cleaning fluid vessels and containers which is capable of elevating discharge waste fluid to water heads greater than present in said fluid vessels and containers, which derives the necessary motive power to drive the cleaning apparatus through fluid kinetic energy provided by a pressurized fluid source and thereby obviates the need for undesirable electrical, chemical, or other mechanical power sources, and which operation is both intuitive and without unexpected action required such that persons of diverse experience, knowledge and skill may readily use the apparatus, comprising: an inlet receiving pressurized fluid from said pressurized fluid source; a divider which simultaneously directs said pressurized fluid to both a jet port outlet and a tank flush source conduit; a siphon return conduit for carrying waste fluid from said fluid vessels and containers; a drain conduit defining a circumferentially closed and longitudinally extensive drain passage; a protrusion circumferentially incomplete about the drain conduit and projecting from a termination of said drain conduit adapted to operatively enable said waste fluid to pass from said fluid vessel into said drain conduit when said drain conduit termination is pressed against said fluid vessels and containers; and a mixing chamber at a junction between said jet port outlet and an outlet from said siphon return conduit, said jet port outlet operative when no waste fluid is passing from said siphon return conduit into said mixing chamber to induce a siphon-generating flow into said drain conduit and said jet port outlet operative when waste fluid is passing from said siphon return conduit into said mixing chamber to introduce a fluid flow of higher velocity than within said waste fluid prior to mixing therewith and thereby transfer kinetic energy into said waste fluid to accelerate said waste fluid into said drain conduit.
