Abstract: The present invention relates generally to a tank overfill protection system (10) designed to be installed in a tank (12). The tank overfill protection system (10) comprises a tank level sensor (14) operatively coupled to a flow control valve assembly (16). The flow control valve assembly (16) is connected to the level sensor (14) via a pilot line (18) which contains a bleed fluid for controlling closure of the flow control valve assembly (16). The tank level sensor (14) comprises a valve body (20), a pilot valve (22) mounted to the valve body (20), and a pilot valve actuator (24) operatively coupled to the pilot valve (22) for its opening and closure. The pilot valve actuator (24) includes a balance member (26) arranged to cooperate with actuator biasing means in the form of a pilot compression spring (28).

The flow control valve (12) generally comprises: 1. a valve body (26) defining a fluid passageway (28) between a fluid inlet (30) and a fluid outlet (32); 2. a piston (34) slidably mounted within the fluid passageway (28) and arranged for displacement for opening and closure of the fluid outlet (32); 3. a bleed fluid cavity (36) located within the valve body (26) and arranged to cooperate with the piston (34); 4. a bleed fluid conduit (38) operatively coupled to the bleed fluid cavity (36); 5. a venturi arrangement (40) operatively coupled to the bleed fluid conduit (38) to promote evacuation of bleed fluid from the bleed fluid cavity (36) thereby opening the fluid outlet (32) by displacement of the piston (34).

Abstract: The present invention relates broadly to a fluid coupling assembly (10) comprising a fluid nozzle sub-assembly (12) arranged to releasably couple to a fluid receiver sub-assembly (14). The fluid nozzle sub-assembly (12) includes a nozzle assembly body (16) defining a pressurised and upstream fluid passageway (18) having a fluid discharge opening (20), and a sleeve (22) slidably mounted to the nozzle body (16) and arranged on sliding movement for opening of the fluid discharge opening (20). The fluid receiver sub-assembly (14) includes a receiver body (26) defining a downstream fluid passageway (28), a hydraulically-actuated poppet valve (30) mounted within the receiver body (26), and a receiver poppet valve (48) including a receiver poppet (54) mounted within the receiver body (26). On coupling of the nozzle sub-assembly (12) to the receiver sub-assembly (14), the following steps occur: 1.

Abstract: The present invention relates broadly and separately to a flow control valve and a float control valve assembly for use in the refilling of storage vessels, particularly fuel tanks. The invention also relates generally to a vessel overfill protection system. The flow control valve comprises a valve body defining a fluid passageway disposed between a fluid inlet and a fluid outlet and a piston assembly located at least in part within the fluid passageway. The piston assembly includes a piston support to which a piston is slidably mounted for opening and closure of the fluid outlet. The piston support includes at least one fluid sampling passage arranged to provide pressurised fluid from the fluid inlet to an upstream surface of the piston which is urged for opening of the fluid outlet to permit flow of fluid through the fluid passageway. The float control valve assembly includes a float assembly body adapted to mount within a vessel to be filled with fluid via the flow control valve.

Abstract: A pressure relief valve and vent assembly include a tank vent including: (i) a vent body having a vent inlet adapted to connect to a tank and arranged to communicate with an exhaust outlet via a fluid passageway; (ii) an exhaust check valve connected to the vent body at or adjacent the exhaust outlet, the exhaust check valve being configured to allow flow in one direction only; and (iii) a pressure relief valve connected to the tank vent inlet and adapted to couple to a tank. The pressure relief valve, when closed, allows for venting air or air/hydrocarbon mixtures from the tank to the exhaust check valve via the fluid passageway. The pressure relief valve, when opened on pressurization of the tank, exhausts tank fluid from the exhaust check valve.

Abstract: The present invention relates broadly to a valve assembly (10) being adapted to detachably receive a dry-break refuelling nozzle (12). The valve assembly comprises a receiver body (14) which defines a forward fuel passageway (16) in which a poppet valve member (18) is slidably mounted. The valve assembly (10) also comprises a tail body (22) secured coaxial with the receiver body (14) and defining a rearward fuel passageway (26). the tail body (22) slidably houses a check valve member or diffuser (28) which is driven by a hydraulic actuator or piston assembly (30).
