    Abstract: An automatic shut-off valve suitable for watering of batteries is disclosed. The valve is formed by a chamber having an inlet and an outlet. A seat surrounds the outlet. A spring biased piston within the cylinder is movable into and out of sealing engagement with the seat to open and close the valve. A flow deflecting surface is positioned between the inlet and the piston. Water flow is directed around the piston to eliminate drag that would force the piston into engagement with the seat. A second deflector surface directs flow against the piston to bias it open. An actuator cup, fed by a nozzle extending from the outlet, draws the piston into engagement with the seat when the cup is sealed by engagement with the electrolyte surface. The valve may also employ a float actuator connected to the piston.

  • Patent number: 6446681
    Abstract: A battery watering unit is mounted atop a battery cell, and includes an open-topped vessel having a bottom wall. A side wall arrangement having an opening at the bottom forms a first divider to partition the vessel into a vented portion and an air entrapping portion. A further side wall arrangement having an opening at the top forms a second divider weir and imposes a significant restriction on the flow of electrolyte from the chamber into a pressure-communicating duct within a downpipe via a restricted orifice. The battery cell is topped up via the vessel with electrolyte following a flowpath over the second divider weir and into the downpipe. As the level of electrolyte rises, the lowermost opening in the downpipe is blocked. A further increase in the level of electrolyte forms, via the air-entrapping portion of the vessel, a pressurized air column in the downpipe which is sufficient to prevent further inflow of electrolyte over the second divider weir.

In another aspect of the invention, a wet battery (15) incorporates a plurality of float valves (75) for regulating the fluid level in respective cells (61, 63) of the battery. Water is passed through a common channel (23) into which the float valves (75) open when the fluid level is below a preset limit. The battery fluid is thereby automatically kept at the required level for optimum performance and lifetime of the battery.

  • Patent number: 6227229
    Abstract: The valve assembly of the present invention includes a body portion having one or more inlets and two aligned outlets. The outlets are located on opposing faces of the body portion, one having a generally rigid valve seat defining a first valve outlet port and the other having a generally flexible valve seat defining a second valve outlet port. The valve assembly also employs a valve support assembly configured to move relative to the body portion generally along the axis of the aligned outlets. The support assembly has a flexible valve member at one end positioned inside the body portion and configured to engage the rigid valve seat to block flow through the first valve outlet port. The support assembly also has a generally rigid valve member positioned outside the body portion and configured to engage the flexible valve seat to block flow through the second valve outlet port.

  • Publication number: 20010000578
    Abstract: A water management system for a motor vehicle in which water is collected from the condenser (1) of the air-conditioning unit, stored in a master water tank (5) and distributed therefrom to the battery (15), screen wash jet (27) and radiator (37). The vehicle owner is thus spared the inconvenience of regularly checking and topping up the water supply for these items. The risk of breakdown is also reduced. In another aspect of the invention, a wet battery (15) incorporates a plurality of float valves (75) for regulating the fluid level in respective cells (61, 63) of the battery. Water is passed through a common channel (23) into which the float valves (75) open when the fluid level is below a preset limit. The battery fluid is thereby automatically kept at the required level for optimum performance and lifetime of the battery.

  • Patent number: 6213145
    Abstract: A golf cart, powered by a plurality of electrolytic, lead-acid batteries has an on-board battery water replenishing system. Each battery includes a manifold that feeds water to each battery cell and is capable of transmitting out of the manifold gas generated during recharging. The watering system includes a water storage tank positioned above the batteries, with inlet and outlet tubing connecting each battery manifold to the tank in a separate, parallel circuit. The outlet tubing has a critical size of internal diameter (ID) to assure the formation of gas generated during recharging as bubbles in the outlet tubing so as to trap liquid between bubbles and to cause flow of liquid back to the tank. A one-way flow control valve is positioned in the inlet tubing to assure unidirectional flow. The outlet tubing ID must be less than ⅜ inch, with a preferred size being ¼ inch.

  • Patent number: 6164309
    Abstract: A liquid filling device for watering batteries comprises a body having first and second water ports that extend through the body and connect within it to first and second water passages that are independent of one another. A trap is disposed the device at a position below the first and second water passages. A bell chamber is disposed at an outlet of the trap and includes an open end. Water passes through the device via a one of the first or second water passages, through the trap, through the bell chamber and into a battery cell. The device traps a volume of air therein and pressurizes the trapped air, as the electrolyte level in the cell rises to a determined level, to an amount at least equal to the head pressure of water in the device, thereby terminating further water flow into the cell. The device includes a gas vent for releasing gas pressure from the cell to the atmosphere or to collection for further treatment.
