摘要： A breakaway coupling including a pair of sleeves, one sleeve fitting within the other, each sleeve provided with a connector body, and a hose connector secured partially with one of the connector bodies. The first sleeve holds a metal annulus, while the second sleeve secures a ring separator, generally counterbored, to secure a series of round magnets, so that when the sleeves and their connector bodies are brought together, they are secured by the magnets into connection, but that when an excessive force is encountered, the breakaway will separate, and prevent further discharge of fuel from the nozzle or its fuel line hose. Connecting with one of the connector bodies is a swivel connector, which can furnish a degree of pivot to the swivel, and its connected nozzle, or the hose, during usage. The swivel connector includes male and female portions, which provide for a degree of pivot, while the male portion further includes a swivel nut, which adds further turnability to the entire unit, during installation.

摘要： A carbon canister with a valve activated by the weight of nearly saturated or saturated carbon communicates with piping from an underground tank. The invention includes carbon within a casing inside a canister, a weight actuated valve, and piping in communication with the atmosphere. When an ORVR vehicle refuels, the pressure lowers in the tank that draws air into the canister. After refueling, the tank remains subject to conditions that generate hydrocarbon vapors. Those vapors then return to the canister and adhere to the surface of the carbon. The carbon, heavier with hydrocarbons, lowers the canister and closes the weight actuated valve. Closing the valve returns pressure control to an external pressure vacuum relief valve. The next refueling draws in atmospheric air to purge the hydrocarbons in the canister and thus lighten it. A secondary purge valve also removes hydrocarbons from the canister. Once the carbon lightens, the inlet valve opens and the vapors return to the canister for adsorption. This cycle regenerates the carbon.

摘要： A fuel dispensing nozzle incorporating a lever assembly that enables a user to more easily and controllably dispense fuel through the nozzle. More particularly, the nozzle has a fuel flow path running through it, with an automatic fuel flow shutoff mechanism and a spring loaded valve assembly with an associated valve stem positioned along the fuel flow path above a lever assembly that regulates the flow of fuel through the nozzle. The lever assembly has a latch plate pivotally connected between the shutoff mechanism and a handle, such that the handle engages the valve stem to provide the user with more leverage to open the valve assembly than is available in conventional nozzle configurations.

摘要： A break away hose coupling for use in conjunction with a vapor recovery nozzle and for application within a fuel line, that prevents untimely decoupling, that only decouples upon the exertion of a pre-determined amount of tension, while preventing unnecessary leakage of fuel and vapors, while being fully reconnectable. The coupling includes a pair of fittings, for connecting to the fuel line, a sleeve for housing the fittings, and each fitting incorporating a check valve to provide for closure of the fluid flow passage and closure of the vapor flow passage when decoupling occurs, a fluid chamber providing for flow of fluid and a vapor return passage, internal of the fluid flow passage, allowing vapor recovery in a concentric line. The device is pressure compensated to eliminate the effects of line shock.

摘要： A fuel dispensing nozzle (10) has a body (12) including a fuel passage for fuel to flow from a source thereof through the body. A spout (18) is attached to the body in fluid communication therewith for fuel to flow into the spout from the passage. The distal end of the spout forms a mouth (19) insertable into the tank. A vapor return path is provided for capturing fuel vapors and returning them to the source, so to substantially reduce or eliminate emissions. A vacuum is produced in a variable venturi portion (42) of the nozzle and is applied to the return path to extract any fuel collecting therein. This vacuum is in addition to another vacuum produced at the venturi and used to assist in automatically shutting-off fuel flow when the tank is full. This device is a power generating source that is not limited to only fuel extraction and nozzle shut off. It can also be used for other apparent uses, having the multiple usage applied in conjunction with the vapor recovery systems in the category of the balanced pressure system and the vacuum assist system.

摘要： A flow control valve for use in dispensing fuel or other fluid and which can be facilely installed in the inlet end of an automatic fuel dispensing nozzle. This flow control valve does not incorporate a valve seat, for its piston like valve, and pressure compensation is controlled by the valve and includes a sleeve incorporating a slidable piston therein, a fluid outlet port is provided at one end of the sleeve, and which is capable of being partially closed by the slide of the piston therein, under fluid pressure conditions, to thereby create a pressure drop that eventually forces the piston into the sleeve and to close off the sleeve port openings in order to reduce fluid flow, during a dispensing function.

摘要： A pressure actuated poppet valve for a fuel dispensing nozzle is disclosed having a piston therein movable between a first and a second position. In the first position, the piston holds a plurality of coupling or latching balls in coupling engagement with an axially movable stem so that upon a user pulling the actuator handle or lever of the dispensing nozzle, the poppet valve is opened for the dispensing of fuel. When the dispenser goes off such that there is no fuel pressure in the hose upstream from the nozzle, a spring within the poppet valve pushes the piston from its first to its second position, thus permitting the coupling balls to move clear of the stem, allowing the poppet valve to close, and preventing opening of the poppet valve upon the subsequent actuating of the nozzle handle. The poppet valve has a flow restriction port which permits fuel to flow in and out of the poppet valve such that a predetermined time delay will result between the time the fuel dispenser is de-energized and the time the dispensing nozzle becomes inoperable. Upon energization of the dispenser, the fuel pressure will cause the piston to move to its first position, thus again enabling actuation of the fuel dispensing nozzle.
摘要翻译： 公开了一种用于燃料分配喷嘴的压力促动提升阀，其具有可在第一和第二位置之间移动的活塞。 在第一位置，活塞保持多个联接或闭锁的球与轴向可移动的杆联接接合，使得当用户拉动分配喷嘴的致动器手柄或杠杆时，提升阀被打开以分配燃料。 当分配器熄灭使得在喷嘴上游的软管中没有燃料压力时，提升阀内的弹簧将活塞从其第一位置推到其第二位置，从而允许联接球移动远离阀杆，允许 提升阀关闭，并且防止在随后致动喷嘴把手时提升阀的打开。 提升阀具有流动限制端口，其允许燃料进入和离开提升阀，使得在燃料分配器断电的时间与分配喷嘴不能操作的时间之间将产生预定的时间延迟。 在分配器通电时，燃料压力将导致活塞移动到其第一位置，从而再次使得能够致动燃料分配喷嘴。
