Abstract: A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.

Abstract: A valve assembly for controlling the filling of a fluid containing vessel is provided having a valve body having a fluid inlet regulated by a valve member movable between an open and closed position within the valve body. A valve controller is provided regulating the valve position having a float pivotally mounted on a float arm and a retaining member pivotally mounted for rotation with the float arm through a limited portion of the float arm range. The retainer member engages the valve member urging it to the open position when the float reaches a predetermined low fill angle and the float arm engages and releases the retainer member when a predetermined high fill level is reached.

Abstract: A method and apparatus for preventing a dense liquid such as diesel fuel from being dispensed into a storage tank that contains a less dense liquid, such as gasoline fuel and vice versa. The unloading process happens by gravity through a vertical down hole. The invention uses the gravitational flow of the fluid, a movable float that is moved by contact with a fluid of a predetermined density, and a magnetic member to activate the stopping feature.

Abstract: The present invention is directed to a gas pressure driven liquid pump having a pump body, liquid inlet, liquid outlet, a pair of pump mechanisms each including a float, and a baffle within the pump body creating two chambers within the pump body. A separate pump mechanism is configured to operate in the respective chambers. The baffle includes a void located below a low liquid level position so that a liquid seal is maintained between the two chambers. As the pump body fills with liquid condensate, a high liquid level position will trigger the respective pump mechanisms to allow motive gas into the chambers, pumping the liquid out of the pump body.

Abstract: A vacuum assisted priming system for a fluid pump including a housing defining a hopper that communicates with a pump inlet. The housing mounts a first port that communicates with the source of vacuum and a second port that communicates with atmosphere. A check valve allows atmospheric air to flow into the housing under certain operating conditions but inhibits reverse flow. A valve member pivotally mounted within a valve chamber carries first and second sealing elements that are engageable with first and second seats. The lever arm is operatively connected to a float via a lost motion connection. When the fluid level in the hopper rises to a predetermined level, an actuating rod moves the lever arm to a first sealing position. When the fluid level falls to a predetermined level, the actuating rod moves the lever arm to a second sealing position.

Abstract: A water supply shutoff valve system is used with a fluid storage tank, such as a hot water heater, to automatically shut off the water supply to the storage tank as a result of leak containment which in turn causes a magnetic float to rise and consequently produce the mechanical force necessary to release and close a spring loaded water supply valve.

Abstract: A liquid level control apparatus for a flush tank includes an upstanding fill tube integral at its upper end with a valve housing carrying a flexible resilient pinch tube valve member. The valve housing defines a conduit which communicates with a downwardly extending tube parallel to the fill tube. A float has portions respectively receiving the fill tube and the downwardly extending tube therethrough so that the float slides vertically along the tubes as the water level in the tank varies. In one embodiment, an actuator rib on the float fits in a slot in the housing to directly engage the pinch tube valve member, and in another embodiment an actuator pivots on the housing and is coupled by linkage to the float. In the one embodiment an arresting flange on a resilient portion of the float engages an arresting flange on the fill tube for arresting upward movement of the float until the tank is full to provide a snap-action shutoff of the valve.

Abstract: An improved float valve assembly is provided for regulating water inflow to a purification module of a water purification system, such as a reverse osmosis purification module or the like. The float valve assembly is mounted within a reservoir for receiving and storing relatively purified water produced by the purification module, and includes a valve unit defining a vertically extending flow path from a tap water source to the purification module. A primary float carried on a float arm responds to rising and falling water level within the reservoir for respectively closing and opening a primary banjo valve mounted along the flow path. An over-center switch provides snap-action closure of the primary valve in response to rising water level, and the primary float is mounted on the float arm for a limited range of lost motion to accommodate this snap-action valve closure.

Abstract: A fill valve for controlling the filling of a fluid reservoir such as a cistern. The valve minimizes the time needed to fill the reservoir by maintaining maximum fluid flow through the valve until instantaneous shut off of the fill valve once the reservoir is filled. The fill valve includes a reciprocating valve head carried on a valve stem connected to a float arm for determining the fluid level within the reservoir. The valve head is disposed within an enclosure having grooves for conducting fluid flow past the valve head to create a back pressure behind the valve head. The valve stem seals a passageway through the valve head which operates as a pilot valve during opening and closing of the valve.

This flexible couple might also allow for some free movement of the float in the direction of the axis of movement of the valve stem. In one embodiment the valve plugs have ported sealing surfaces that allow gradual starting and stopping of the flow of fluid through the valve outlets.

A follower moves a poppet valve axially with a housing as a nonlinear function of rate of cam rotation. The poppet valve is moved to a closed position to terminate flow of a liquid to the storage tank whenever the liquid level within the storage tank reaches a predetermined level.

Abstract: An irrigation system includes one or more valve assemblies which are connected in series to a pressurized source of water. Each valve assembly includes a cylindrical housing, a ball valve, an inlet and two outlets with one outlet generally opposite from the inlet in a lower portion of the housing. The other outlet is disposed in an upper portion of the housing and adapted to direct water to an area of ground for irrigation. A pit and float are associated with each valve assembly and arranged so that some of the irrigation water will flow into the pit and raise the float. The float is connected to spring biasing means and when the float reaches a predetermined level, the ball valve will spring upwardly to close the upper outlet and redirect the water to another assembly. Water pressure will then maintain the valve in that position.
