Abstract: A toilet flushing and cleaning device includes a reservoir with a cylinder and a mixing tube disposed therein. The cylinder communicates with a water source. A plunger is slidably disposed in the cylinder. A plurality of spray nozzles communicate with the mixing tube. When a flush valve is opened to allow water into the cylinder, the piston is driven upwards. The increase in air pressure drives pressurized air and water into the mixing tube such that the spray nozzles clean the toilet with a burst of air-water mixture. In a further embodiment, a funnel is disposed in the toilet bowl and a bucket is suspended at the lower opening of the funnel. When the piston is driven upwards, the bucket is pivoted to release its contents. Additionally, a blower disposed between the funnel and the toilet bowl may be used to drawing air and odors from inside said funnel and directing air into said toilet bowl for release through the existing drain pipe and vent pipe.

Abstract: A pressurized flushing system for discharging liquid into a toilet bowl. The mechanism comprises a sealed container for storing a pre-determined volume of the liquid under pressure having an inlet for connection to a liquid supply source under pressure and an inlet valve to permit liquid flow through the inlet until the pre-determined volume in the sealed container is reached. There is an outlet for discharging liquid under pressure and an outlet valve movable between an open position to permit liquid discharge through the outlet and a closed position to seal the outlet. The outlet valve is urged by internal pressure within the sealed container toward an open position of the outlet when the pre-determined volume of liquid is in the sealed container, however, an actuator normally locks the outlet valve in the closed position against the internal pressure of the container. Operation of the actuator by a user unlocks the outlet valve to permit movement of the outlet valve to the open position.

Abstract: A low volume high-pressure toilet. When the user sits on the toilet seat, a hydraulic piston pressurizes the water tank, which optimally holds 1.7 liters of water. Water is released at high pressure through the toilet interior rim and a lower waterjet, forcing the wastewater down a waste pipe. To minimize velocity pressures losses that would be caused by a p-trap, the waste is released straight down a pipe. Sewer gases are prevented from traveling back up the pipe by a sealing valve that occludes the cross sectional area of the waste cavity in the bottom of the toilet.

Abstract: A pressurized water closet operating system comprises a water vessel, an external manifold mounted directly on said vessel, and an internally mounted flush valve assembly.

Abstract: A toilet flushing system includes a fresh water feed, a fluid storage container connected to the fresh water feed, and a supply line coupled to the storage container and a toilet. The fluid storage container has a container casing and first and second separating diaphragms within the casing. The separating diaphragms define first, second and third partial chambers within the container casing for separately receiving gas and fresh water. The second partial chamber is defined between the separating diaphragms and receives gas. A valve in the fresh water feed and the supply line, closes the fresh water feed and the supply line. The valve is movable between a first switch position for filling the partial chamber with fresh water to be delivered to the toilet and a second switch position in which the third partial chamber simultaneously is filled with a medium.

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 source (12, FIG. 1) is provided for mounting on a toilet housing (32) rearward of the toilet bowl (18), which has a small rearward-to-forward depth (D) and low height (H), and which enables close control of the flow of water and any vacuum to the toilet bowl and its outlet. The source includes a frame (40) for mounting on the rearward portion of the toilet housing, the frame having two wide holes (50, 52) and a diaphragm device (54, 56) extending across each hole to separate water regions (60, 62) from air regions (64, 66) that lie on opposite sides of the diaphragm. The holes and diaphragms form two horizontally spaced water supply units 42, 44 that lie on opposite sides of the toilet bowl outlet 24 to efficiently use space. A spring or weight biases each diaphragm to compress the water region. The two water regions are connected together and to a flush valve (14) for supplying water to the toilet bowl.

Abstract: A pressurizable flushing toilet includes a pressurizable water container having a movable stopper closing a water discharge outlet in the container. A controller energizes a solenoid to move the stopper between an outlet closing position and an outlet opening position. A water level sensor is mounted in the container and supplies a signal to the controller indicative of the build-up of a predetermined level of water within the container. The controller activates a compressor to pressurize air in the container above the water to a predetermined pressure level. A pressure sensor is mounted in the container and generates an output signal when a predetermined pressure level is reached within the container.

Abstract: A pressurized water closet operating system comprises an accumulator vessel having a flush valve assembly mounted internally thereof both of which are connected at all times to a source of water under pressure.

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.

Abstract: A pneumatic actuating device for a toilet flush valve, comprising a cap emplaced on the flush valve housing and having an integral hemispherical bell member extending laterally therefrom, the bell member containing a resilient membrane. A manual pusher provided with a similar hemispherical membrane is connected to the bell member by a hose. A pipe which carries the flush valve plate is connected to a hood having a piston which extends into the membrane in the bell member. Upon actuation of the manual pusher, air flows through the hose, deforming the membrane in the bell member and causing it to lift the piston, thereby opening the flush valve.

Abstract: This invention comprises an improved hydraulically operated flush valve for toilet flush tanks and similar devices. Its main components are a cylinder and piston assembly positioned with its longitudinal axis directly above and vertically aligned with the vertical axis of the outlet or flush tube of the flush tank. The moveable piston within the fixed cylinder acts as the moving and sealing element of the flush valve. By means of an inner valve connected to the flush tank operating lever hydraulic force is caused to lift the piston thereby opening the flush valve. There is no direct mechanical connection between the operating arm and the flush valve, and there are no chains or hinges. There is a positive permanent flush valve alignment and a minimum of friction. In addition, the amount of water used per flushing action can be regulated to prevent water and energy wastage.
