摘要： 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. The float control valve includes a pilot valve and a pilot control passage in fluid communication with the flow control valve. The pilot valve is operatively coupled to a float member for closure of the pilot control passage on flooding of the float housing to promote closure of the flow control valve.

摘要： 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 balance member (26) is in the form of a counterbalance and has a specific gravity relative to liquid or fuel within the tank (12) so that at least part submersion of the balance member (26) under the influence of the pilot compression spring (28) provides movement of the balance member (26) and closure of the pilot valve (22). This closure of the pilot valve (22) substantially closes and subsequently pressurises the bleed fluid in the pilot line (18) for closure of the flow control valve assembly (16).

摘要： 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. the receiver body (26) abuts the sleeve (22) displacing it axially relative to the nozzle body (16) exposing and thus opening the fluid discharge opening (20) permitting fluid to flow through the upstream fluid passageway (18); 2. the fluid flowing through the upstream fluid passageway (18) enters the downstream fluid passageway (28) hydraulically actuating the hydraulically-actuated poppet valve (30) to open it wherein the fluid flows through the downstream fluid passageway (28) exiting the receiver sub-assembly (14).
