Hydraulic tank assembly for a water closet

Abstract

Abstract A HYDRAULIC ASSEMBLY FOR FILLING AND RAPIDLY DISCHARGING A LIQUID FROM A HERMETICALLY SEALED TANK. VERTICALLY POSITIONED IN THE TANK IS A CHUTE HAVING AN OPEN LOWER END AND A CLOSED UPPER END AND HAVING AN APERTURE OPENING INTO THE LOWER PORTION OF THE TANK. A VALVE SEAT EXTENDS AROUND THE INNER PERIPHERY OF THE CHUTE POSITIONED BELOW THIS APERTURE, WHILE POSITIONED WITHIN THE CHUTE IS A VALVE HEAD WITH A STEM. THE VALVE HEAD IS CAPABLE OF VERTICAL MOVEMENT FROM AN OPEN POSITION ABOVE THE APERTURE TO A CLOSED POSITION IN SEALED ENGAGEMENT WITH THE SEAT. ON THE VALVE STEM IS A ROLLING DIAPHRAGM DISPOSED FOR VERTICAL MOVEMENT IN THE CHUTE. MANUAL MEANS ARE ASSOCIATED WITH THE STEM FOR MOVING THE VALVE HEAD FROM THE CLOSED TO THE OPEN POSITION, AND SPRING MEANS, NORMALLY RESISTING UPWARD MOVEMENT OF THE VALVE HEAD WHEN THE VALVE HEAD IS SEATED, ARE DISPOSED ABOVE THE ROLLING DIAPHRAGM AROUND SAID STEM. THERE IS ALSO AN AIR VENT AND CHECK VALVE PASSING THROUGH THE TANK. THE CHECK VALVE MOVES TO A CLOSED POSITION WHEN LIQUID IN THE TANK RISES TO A PREDETERMINED LEVEL AND FALLING TO OPEN THE VENT TO THE ATMOSPHERE WHEN LIQUID FALLS BELOW THIS LEVEL. PRESSURIZED WATER IS SUPPLIED INTO THE TANK BY AN INLET CONDUIT. OPERATION OF THE MANUAL MEANS WILL OPEN THE VALVE HEAD, FORCING THE LIQUID TO FLOW THROUGH THE APERTURE AND OUTWARDS FROM THE CYLINDER, THE FLOW THEREOF BEING AUGMENTED BY COMPRESSED AIR PRESSURE ACTING TO RAPIDLY FORCE LIQUID THROUGH THE APERTURE AND OUT OF THE CYLINDER.
