    Abstract: A fluid flow control valve (10) has a piston (43) in a first chamber (45), urged by a spring (46) to close fluid passages (36) interconnecting the first chamber (45) to a second chamber (51). A fluid level sensor (20) in a container (100) allows fluid to be bled from a downstream side of the first chamber (45), via a bleed passage (45), to enable the piston (43) to move to open the fluid passages (36). When the fluid sensor (20) detects that the fluid level (101) in the container (100) has reached a preset level, the fluid level sensor (20) shuts off flow through the bleed passage (45) and the equalization of the fluid pressure on both sides of the piston (43) in the first chamber (45) enables the spring (46) to move the piston (43) to close the fluid passages (36), shutting off fluid flow through the valve (40).

  • Patent number: 5815850
    Abstract: A toilet bowl cleansing apparatus is positioned in a toilet tank between the toilet bowl refill tube and overflow protection pipe. The apparatus comprises a sealed container having an inlet connected to the refill tube and an outlet communicating with the overflow pipe. The interior of the container is divided into two chambers by a partition having screens at each end. One chamber houses a block of cleansing agent and the other chamber allows ingress of water into the container. As water from the refill tube enters ingress chamber, it flows through one of the screens in the partition and mixes with part of the cleansing agent block to form a cleansing solution. Compression of the air in the container permits only a portion of the block to erode at a time since the internal pressure forces the solution to exit the container before the block is completely covered by water.

  • Patent number: 4709721
    Abstract: An improved ballcock assembly for a toilet water reservoir which provides quiet reservoir refill operation without requiring a conventional water discharge hush tube. Quiet refill operation is provided by discharging refill water through a plurality of openings which create individual streams of water which flow along the side surfaces of a standpipe having longitudinally extending external ridges or walls. The walls maintain the separation of the individual water streams which cascade down the standpipe surface. The outside surface of the standpipe is preferably tapered outwardly from top to bottom so that the water flows along a tapered surface which reinforces the cascading flow regime. The reduced flow for each stream and the cascading flow action combine to provide quiet refill operation. Since the ballcock assembly refill openings are above reservoir tank water level, water normally cannot be sucked through them and into the water supply system.

  • Patent number: 4420845
    Abstract: A valving system capable of maintaining a substantial flow rate to a low profile toilet bowl during bowl wash, bowl flush and refill, and storage tank refill. The system includes a tank refill tube and a bowl wash tube, with an adjustable restriction in one of them to balance the flow between them. When the toilet is flushed, water from the storage tank is emptied into the toilet bowl, causing the bowl contents to start to siphon out. A level-responsive valve opens when the tank level lowers, and supplies water both to the tank to refill it, and to the rim. It flows from the rim to wash the walls, to continue the flush, and to refill the bowl. A flow control can usefully be placed upstream from the valve so that a substantially constant flow rate results which is able to be accurately divided between the tank and the bowl, so that all functions are completed by the time the tank is refilled.

  • Patent number: 3982557
    Abstract: A fluid flow control valve for automatic fluid level control in a reservoir is provided having a valve chamber with axially aligned inlet and outlet orifices, a valve closure element disposed in the chamber and having an actuating stem projecting outwardly through the outlet orifice, and a float-type lever arm engageable with the actuating stem. The valve closure element is normally maintained in closing relationship to the outlet orifice by the pressurized fluid at the inlet side with the valve designed for operation over a wide range of fluid pressures. Movement of the lever arm in response to the fluid level is effective in rocking the valve closure element through its actuating stem to a position where fluid may flow through the outlet orifice. The lever arm is provided with a weighted float to assure positive operation of the valve in high pressure fluid systems and the lever arm is formed with means readily permitting adjustment thereof to precisely determine the fluid level in the reservoir.
