Abstract: A canister type flush valve has an upright cup-shaped hollow float working under buoyancy forces without a captured air volume that controls the valve during a flush cycle. Hooded bleed openings at a bottom wall of the float can be sized and numbered to selectively control the closuring timing of the valve. Baffles of the hood bleed openings redirect water bleeding into the float to prevent the water from spraying up against the top of the tank. The geometry of a seal retaining groove is designed to reduce leakage at the float/seal interface. For example, the groove has an annular wall with a compound profile forming a non-cylindrical, preferably serpentine, seal contact area. The seal is backed by a slotted flange located just above the retaining groove.

Abstract: A water toilet has a valve arrangement of the integrated type, i.e. the float and all valves form a unit which in its mounted position is connected to the outlet pipe of the flush water container. According to the invention the unit is loosely connected to said pipe and mechanically retained at its top end by means cooperating with the inner surface of the top portion of the water container wall.

Abstract: Toilet flush tanks run completely empty when the actuating device is actuated briefly. In very many cases this is not necessary. Therefore, a toilet flush tank is proposed where the drain closure part, actuated by a closing force, closes the drain. The closing force can either occur automatically after the water level has dropped accordingly, or it can be released manually when the water level is observed visually.

A central mounting portion is secured to a pair of telescoped tubes. A flexible diaphragm with a circular convoluted fold integrally connects the mounting portion and the outer sealing portion, and is capable of yielding to permit radial and/or tilting displacement of the outer sealing portion relative to the central mounting portion of the plug to accommodate limited misalignment between the valve tubes and the drain hole.

Abstract: A toilet tank has water supply and overflow ducts which are integrally formed with the base and walls of the tank. The water supply duct is connected to a water inlet at one end to supply water to the tank and has an inlet valve at its other end to control the supply of water to the tank. The overflow duct is open at its top to receive overflow water in the tank and is coupled to the toilet basin to pour the overflow water into the toilet basin.

Abstract: A flush valve control apparatus for selectively closing, at the option of the operator, the flush valve of a flush toilet is disclosed. The apparatus includes a control member which is located such that it can selectively push against the flush valve which opens and closes the outlet pipe of a flush toilet. The control member which is normally in a non-control relationship with the flush valve is attached by a hinge to the standpipe such that it may be rotated downwardly until it contacts the top portion of the valve. A rod is pivotally attached to the control member at one end and slidably attached to a line at its second end. The link is attached to the handle of a trip lever, such as is normally found in conventional toilets. On forcing the trip lever downward by rotating the handle in a direction opposite to that for flushing, the link slides along the rod until it meets a stop.

Abstract: A flushing mechanism is disclosed for use in the tank of a toilet, utilizing a spool valve to accommodate various fluid pressures and to accomplish accurate control of volumetric flow. A housing is provided in the toilet tank, defining an inlet port which is adapted to be connected to the source of flushing fluid, e.g. water, and also defining a vertical valve chamber extending somewhat transverse to the inlet port and connected to control the discharge of water from the valve and out of the tank to the toilet bowl. The spool valve is provided in the valve chamber such that the facing surfaces of lands on the spool are subjected to the pressure of the flushing water source, to maintain a balance. Manual means is disclosed for displacing the spool valve to supply flushing water from the source while activating a hydraulic timer which, in due course, resets the spool valve. In the disclosed embodiment, the hydraulic timer involves a bleed tube for supplying water to the tank which contains a float.

Abstract: A two-stage toilet flush mechanism is provided in which operation of the usual control lever to a yieldable manually-felt detent point produces a partial flush the duration of which is controlled by the position of first float with respect to the initial water level in the storage tank, and movement of the lever beyond the detent point produces a complete flush the duration of which is controlled by the position of a second float with respect to the initial water level.
