Abstract: An apparatus for flushing a water closet bowl includes a pressurizable reservoir, within which is formed a primary and a secondary pressure zone. Formed at the bottom of the reservoir is an exit aperture through which the pressurized fluid is discharged into the bowl. Movably disposed within the reservoir is an elongate piston member. Formed at the top of the piston member is a hollow cup, which is movably disposed within a downwardly extending hollow cylinder within which is formed the secondary pressure zone. Formed at the bottom of the piston is a plug which seals the exit aperture. During a flushing action, pressure within the secondary pressure zone is released by operating a flushing lever, and the piston moves upwardly so as to release the plug from the exit aperture. In one embodiment, the flushing apparatus includes a fluid inlet regulator that controls the amount of fluid that is introduced into the reservoir from a fluid supply line.

Abstract: A water saver toilet is provided, of the type that applies a vacuum to the toilet bowl outlet to assist flushing, which effectively uses the vacuum and which can be of low height. The toilet bowl outlet includes upper and lower trap devices (44, 50 in FIG. 2) connected by a trapway (46), with a vacuum source applied to the trapway during a flushing to pull out water and debris from the toilet bowl. One vacuum source (FIG. 3) includes a largely horizontal diaphragm (76) which separates a water chamber (82) from a vacuum chamber (80). The water chamber is initially filled with water, which is rapidly emptied during flushing, causing the diaphragm to rapidly fall from an upwardly bowed configuration (76) to a downwardly bowed configuration (76A). The vertically moving diaphragm produces a vacuum in the vacuum chamber that is connected to the trapway.

Abstract: A diaphragm valve for a toilet flushing mechanism, and a hydraulic flushing assembly using the valve, control water mains pressure for the pressure flushing of toilets with small quantities of water. Water mains pressure is used to retain a flexible diaphragm against the orifice through which flushing water from a pressurized tank can flow through the valve when flushing action is desired; flushing is initiated by temporarily lowering the water pressure applied to retain the diaphragm. Various designs of pressurized tank can be used to provide a constant or variable volume flush, which can be less than six quarts or liters.

A flush valve is provided in the drain line between the toilet bowl and the waste-holding tank and is selectively operable to pass the toilet bowl contents into the waste-holding tank. Water from the potable water supply system is provided to the toilet bowl to wash the sides of the toilet bowl and to assist in moving the waste material to the drain line. A water inlet valve is provided to selectively control the introduction of water into the toilet bowl and preferably the water inlet valve and flush valve are operated in a timed sequence by actuation of a single flushing switch.

Abstract: A water-conserving toilet is disclosed and includes a bowl for receiving waste and a waste outlet extending laterally from the bowl and defining a first, shallow trap arranged so that a relatively shallow body of liquid is normally retained in the bottom of the bowl for preventing gaseous flow through the trap. A flush system is provided and is arranged, when operated, to deliver a charge of flushing liquid into the bowl in a direction to cause said body of liquid to be discharged through said outlet. An enlarged chamber communicates with said bowl outlet for receiving waste from the bowl. An outlet extends outwardly from the chamber and is adapted for connection to a sewer inlet. The chamber outlet defines a second trap of substantial height capable of preventing reverse flow of sewer gas into the chamber in use.

Abstract: A water reservoir tank storing a primary body of water for release to a toilet bowl for flushing is associated with a pressure tank that stores a minor amount of water at a pressure considerably higher than that of the primary body and is discharged during flushing to join the water released from the reservoir tank and impart increased overall energy to the water in the bowl. A predetermined time delay is introduced between start of the flushing action and discharge of water from the pressure tank. The pressure tank is automatically discharged and recharged during each flushing cycle.

Abstract: A water closet of the tank type in which air is entrapped in the tank creating pressure to assist in expelling flushing water to a bowl during the flushing cycle. The flushing cycle is activated by a disc valve and piston connected to a domestic water supply for dislodging a float and valve from a valve seat. The water closet is constructed with a minimum of moving parts by employing a piston for dislodging the float which temporarily cuts off the flow of water to the bowl and utilizes the water pressure for returning the piston to the static position. The system also employs a vacuum breaker assembly having a ball in an angled pipe maintained by gravity against a seat in the flushing water line. The force of the water flowing into the bowl forces the ball from the seat during flushing. The ball returns to the seat by the force of gravity on the completion of flushing, preventing back pressure from any vacuum in the domestic water supply.

The pressure tank is automatically discharged and recharged during each flushing cycle.
