Sequencing valve

Claim 1

A SEQUENCING VALVE, COMPRISING: A VALVE HOUSING HAVING INLET MEANS AND AT LEAST TWO SPACED OUTLETS; CEILING, SIDE AND FLOOR WALLS WITHIN SAID HOUSING PROVIDING AN ENDLESS FLOW PASSAGE INTERCONNECTING SAID INLET MEANS AND SAID OUTLETS, SAID WALLS INCLUDING A SERIES OF INTERCONNECTED SLOPING CEILING SURFACES AND A SERIES OF INTERCONNECTED SLOPING FLOOR SURFACES, MEANS INTERCONNECTING THE HIGH POINT OF A CEILING SURFACE WITH THE LOW POINT OF AN ADJOINING CEILING SURFACE, AND MEANS INTERCONNECTING THE HIGH POINT OF A FLOOR SURFACE WITH THE LOW POINT OF AN ADJOINING FLOOR SURFACE, SAID INLET MEANS BEING DISPOSED AT THE LOW POINTS OF SAID SLOPING FLOR SURFACES AND SAID OUTLETS BEING DISPOSED AT THE HIGH POINTS OF SAID CEILING SURFACES, THE HIGH AND LOW POINTS OF A SLOPING CEILING SURFACE BEING OFFSET LONGITUDINALLY OF SAID FLOW PASSAGE RELATIVE TO THE HIGH AND LOW POINTS OF A SLOPING FLOOR SURFACE SO THAT THE LOW POINT OF A FLOOR SURFACE IS DISPOSED BETWEEN THE HIGH AND LOW POINTS OF A CEILING SURFACE: VALVE MEANS, NOT MORE THAN ONE LESS THAN THE NUMBER OF OUTLETS, FREELY MOVABLE IN SAID FLOW PASSAGE, SAID VALVE MEANS HAVING A DENSITY GREATER THAN THAT OF THE CONTROLLED FLUID AND COOPERATING WITH SAID OUTLETS TO CONTROL FLOW THROUGH SAID OUTLETS; SAID SLOPING CEILING SURFACES BEING INCLINED IN A DIRECTION OPPOSITE TO THE INCLINATION OF THE SLOPING FLOOR SURFACES TO ADVANCE SAID VALVE MEANS IN A SINGLE DIRECTION THROUGH SAID FLOW PASSAGE; WHEREBY EACH VALVE MEANS IS FREELY MOVABLE BY THE FORCE OF FLUID FLOW FROM SAID INLET MEANS THROUGH SAID FLOW PASSAGE AGAINST SAID VALVE MEANS, IN COOPERATION WITH SAID SLOPING SURFACES, FROM A POSITION ADJACENT AN INLET MEANS AT THE FOOT OF ONE OF SAID FLOOR SURFACES IN PROXIMITY WITH A CERTAIN OUTLET TO A POSITION OBSTRUCTING SAID CERTAIN OUTLET TO BE MAINTAINED IN SUCH OBSTRUCTING POSITION BY FLUID PRESSURE IN SAID FLOW PASSAGE, AND MOVABLE Y THE FORCE OF GRAVITY, UPON CESSATION OF FLUID FLOW THROUGH SAID FLOW PASSAGE SAID THE LOWERING OF FLUID PRESSURE THEREIN, FROM SAID OBSTRUCING POSITION AND TO BE MOVED DOWN THE INCLINE OF A FLOOR SURFACE TO A POSITION ADJACENT AN INLET MEANS AT THE FOOT OF SAID FLOOR SURFACE, FROM WHICH LATTER POSITION SAID VALVE MEANS MAY BE MOVED INTO A DIFFERENT POSITION BY THE FORCE OF FLUID FLOW DIRECTED AGAINST SAID VALVE MEANS AND BY A SLOPING CEILING SURFACE INTO REGISTER WITH A NEXT OUTLET, TO OBSTRUCT FLOW THEREFROM, WHEN FLUID FLOW IS RESTORED THROUGH SAID INLET MEANS AND THROUGH SAID FLOW PASSAGE.
