摘要： A fill valve assembly for a water tank such as a toilet tank. The fill valve assembly includes a head portion containing a valve mounted on top of a vertical water outlet tube and a float which moves vertically along the outlet tube to control the opening and closing of the valve. The float is vertically adjustable without removal or disassembly of the valve assembly in order to adjust the tank water level to a preselected position. The float includes an inverted cup-shaped structure which moves vertically along the outlet tube in response to any change in the water level. The valve contains a flexible main valve disk held in a closed position against a valve seat by water pressure in a control chamber to prevent the flow of water into the tank, and is moved to an open position upon venting of the control chamber. A pilot valve controls the pressure in the control chamber and, therefore, the movement of the main valve disk. The pilot valve is controlled by a lever mechanically connected to the float so that when the float drops with the falling water level the pilot valve is opened, thereby venting the control chamber and allowing the main valve disk to flex upwardly off of the valve seat to allow water to enter the tank. When the float rises with the rising water level to an upper predetermined position, the pilot valve is closed by the lever and the main valve disk is returned to its closed position against the valve seat to block the flow of water into the tank.

摘要： The present invention relates to a WC-cistern filling valve comprising a liquid inlet assigned to a supply line, a liquid outlet assigned to the cistern, and a closing element which is assigned to a valve passage opening arranged between liquid inlet and oulet and which is switchable by a float in accordance with the liquid level in the cistern for opening and closing the valve passage opening. It is the object of the present invention to provide a low-noise WC-cistern filling valve. This object is achieved in that at least a portion of the liquid outlet is shaped as a thread in the flow direction downstream of the closing element in such a manner that liquid is discharged with a swirl from the liquid outlet to the cistern in the opened state of the closing element.

摘要： A float-operated valve assembly for a water tank includes a valve housing provided inside the water tank and connected to an external water source. The valve housing has an outlet opening formed at an intermediate portion thereof. A ratchet pole extends into the valve housing and has an end portion which is formed with aligned ratchet teeth. The ratchet pole is provided with a stopper that is urged by water from the external water source so as to cut off water flow to the water tank. The float ball of a float ball assembly urges a pivot arm to apply a pushing force on the end portion of the ratchet pole so as to move the stopper and permit water flow to the water tank when water inside the water tank no longer applies a buoyant force on the float ball. A float-controlled pawl engages the ratchet teeth of the ratchet pole when water inside the water tank is below a predetermined level, thereby maintaining the stopper in an open position when the water tank is being refilled. The pawl disengages the ratchet teeth when water inside the water tank is at least equal to the predetermined level, thereby permitting water from the external water source to urge the stopper to cut off the water flow to the water tank when the water tank has been refilled.

摘要： A float operated valve is provided with the rise of a float being temporarily prevented by the elastic force of a spring mounted on the valve body. When the buoyant force of the float reaches a predetermined maximum buoyant force as a result of the water level rising and the float becoming increasingly submerged, the buoyant force of the float moves the spring and closes the valve. The valve is also shown with a twin float construction for on/off operation at low and high water levels.

摘要： A float valve mechanism for a cistern or tank comprising a housing (20,22) defining a closed chamber (24) having an inlet port (26) connected to an inlet pipe (16) to the cistern or tank, an outlet port (28) from the chamber having a valve seat (30) surrounding the port. A valve member (34) passes through the opening and has a valve head located within the chamber, the valve head being integrally formed, preferably from a plastic material, with a lever (38) which is pivotal about axis (42) and carries a float (54). The valve head (36) is pivotally movable an integral manner with the lever along a path passing through the outlet port (28) of the chamber. Water pressure within the chamber normally urges the valve to the closed position and the weight of the float when the water has fallen below a given level in the tank overcomes this pressure to allow water to flow from the chamber into the cistern.

摘要： This invention comprises an assembly (10) for controlling the level (64) of fluid, such as water (14), in a container (11), which invention includes a source of supply (29) for discharging the water (14) into the container (11), a valve (21) connected to the water source (29), a float (23) pivotally connected to the valve (21) for holding said valve (23) open or closed, depending upon the level of fluid in the container (11); the assembly (10) comprising a bracket (31) pivotally mounted within the container (11) and fastened to the valve (21) and float (23) as a unit, and a shaft (57) and screw (49) combination seated in a wall (33) of the container (11), with one end of the screw (49) non-rotatably mounted in the bracket (31), the shaft (57) manually rotatable from external the container (11) which rotation results in longitudinal movement of the screw (49) relative to the shaft (57), thereby pivoting the bracket (31) upwardly or downwardly in the container (11), resulting in varying very slightly--or more as the case may be, the position of the float (23) and thus varying accordingly the opening or closing of the valve (21) and the level (64) of water (14) within the container (11).

摘要： Hose connector adapter apparatus for an evaporative cooler float valve includes an integral ferrule for sealing the float valve to the adapter and an internal hexagonally configured passageway through which the water flows and which passageway receives a hex wrench or the like for securing the adapter to the float valve when there is insufficient external clearance for manually securing the adapter to the float valve. The adapter apparatus is able to be secured to evaporative cooler float in virtually any location on a cooler housing, regardless of the cooler housing configuration either by manually securing the adapter or by using a wrench internally.

摘要： A magnetically-operated valve has a body provided with a passageway therethrough. A piston is mounted on the body for sliding movement toward and away from a valve seat. The piston has a magnetic pole at one end. A magnet is mounted on the body for movement between a first position, at which the piston will be held in a flow-permitting position, and a second position, at which the piston will sealingly engage the seat to terminate such flow. An override mechanism may be operated to displace the piston against the repulsive forces between like poles.
