Abstract: A testable overfill prevention valve (“TOPV”) for a liquid storage container. The TOPV allows an individual to readily verify the operability of the TOPV. Preferably, a test member of directly contacts a portion of a latch to release a flow control member so that the flow control member can move from an open position to a closed position wherein in the closed position liquid is generally prevented from flowing out the TOPV. The test member preferably directly contacts the flow control member to move the control member to an intermediate position between open and closed positions allowing an individual looking down into the TOPV to see that the flow control member has moved sufficiently to confirm operability of the TOPV. Preferably, the test member is spring biased to a non-testing position and the entire test member is disposed in the housing of the TOPV when in a testing position.

Abstract: A manhole cover assembly removably supported by a manhole skirt or rim wherein when the manhole cover assembly is removed from the manhole skirt or rim an individual can access one or more components (e.g., underground fuel storage tank) through an opening in the manhole skirt or rim. Preferably, the manhole cover assembly is light weight and very strong so that there is little or no deflection of the cover of the manhole cover assembly when subjected to a predetermined load. Preferably, the manhole cover assembly is adapted for use in refueling stations to withstand the load placed thereon when a refueling tanker or other vehicle runs over the manhole cover assembly with little or no deflection of the cover of the manhole cover assembly. Preferably, the assembly forms a liquid tight seal with the manhole skirt to prevent liquid from passing into the storage area below the skirt.

Abstract: An apparatus for repairing an existing spill containment manhole operably associated with an underground fuel storage tank. The apparatus includes a containment vessel for containing fuel spilled during filling of the underground fuel storage tank. A major portion of the containment vessel is adapted to be inserted into an existing spill containment manhole. Preferably, the containment vessel includes an upper annular flange that extends over and surrounds a portion of an existing cover rim of an existing spill containment manhole thereby isolating an upper portion of the containment vessel from an upper portion on the existing spill containment manhole when the containment vessel is installed. Optionally, a replacement cover is provided to replace an existing cover of the existing spill containment manhole. The replacement cover may include at least one sealing member that engages the inner surface of the at least one wall of the containment vessel when installed.

The apparatus includes a containment vessel for containing fuel spilled during filling of the underground fuel storage tank. A major portion of the containment vessel is adapted to be inserted into an existing spill containment manhole. The containment vessel includes at least one wall that surrounds an existing pipe section operably associated with the underground fuel storage tank when the containment vessel is installed. The at least one wall has an inner surface and an outer surface. Preferably, the containment vessel includes an upper annular flange that extends over and surrounds a portion of an existing cover rim of an existing spill containment manhole thereby isolating an upper portion of the containment vessel from an upper portion on the existing spill containment manhole when the containment vessel is installed.

Abstract: A nozzle for dispensing fuel into a vehicle having a body portion and a spout extending from the body portion. The spout passes fuel from the body portion to a vehicle during refueling. The body portion includes a fuel flow control member for allowing or preventing fuel from passing through the body portion and the spout. A fuel collector collects fuel remaining in the body portion and the spout after the fuel flow control member shuts-off the flow of fuel through the body portion and the spout. Preferably, the fuel collector is configured to allow fuel collected in the fuel collector when the vehicle is being refueled to drain into the fuel tank of the vehicle after the flow control member prevents fuel from passing through the body portion and the spout but prior to removal of the spout from the fuel tank of the vehicle.

Abstract: A nozzle for dispensing fuel into a vehicle. The nozzles includes a body portion and a spout extending from the body portion. The spout passes fuel from the body portion to a vehicle. The body portion includes a fuel flow control member for allowing or preventing fuel from passing through the body portion and the spout into the vehicle. The spout has first and second portions. The first portion of the spout is positioned adjacent the body portion and the second portion of the spout is removed from the body portion. Preferably, at least one fuel collection member is provided for collecting fuel remaining in the body portion and the spout after the fuel control member shuts-off the flow of fuel through the spout to prevent dripping of fuel from the end of the spout.

Abstract: An overfill prevention device for storage tanks includes an elongate tubular housing having a liquid flow passageway. A normally open main valve and a normally closed vapor retaining bleed valve are associated with the fluid passageway. Closure of the main valve interrupts the primary flow of liquid through the passageway and closure of the bleed valve prevents any further liquid from entering the tank and also prevents the escape of vapors from the tank. Operation of the main valve is controlled in significant part by a valve latch assembly which is carried by the housing and a relatch assembly which is carried by the main valve. The relatch assembly ensures operative engagement of the main valve with the valve latch assembly upon movement of the main valve from the intermediate position to the open position. Operation of the main valve and vapor retaining bleed valve is also controlled indirectly by a plurality of floats which are maintained in a float chamber extending adjacent the liquid passageway.

Abstract: A fuel dispensing and vapor recovery nozzle having a fuel passageway therethrough, a main valve in the fuel passageway for controlling the flow of fuel therethrough, a manually operable valve actuating lever for opening the main valve, a venturi responsive to fuel flow through the fuel passageway for creating a vacuum, a shut-off passageway from the venturi to the spout adapted to be closed when the fuel tank is filled, a vapor recovery passageway extending longitudinally therethrough and a check valve in the vapor recovery passageway mounted on the spout and having an open condition allowing vapor to pass therethrough and a closed condition so as to block liquid fuel flow through the check valve and out the spout of the nozzle.
