摘要:
Method of filling a fuel tank (1) of a motor vehicle (10) by means of a nozzle (23) connected by a distribution unit (22) to a fuel source (21), the method comprising the steps of: connecting the nozzle to the tank and activating the distribution unit to begin the filling; establishing a link between a management unit (3) of the vehicle and a fill detector (4) to prevent the motor from starting when it is detected that filling is in progress. An object of the invention is also a corresponding device.
摘要:
The fuel dispensing nozzle (10) has a body (12) in which a fuel passage is formed. A spout assembly (18) is attachable to the body in fluid communication therewith for fuel to flow from the body through the spout and into a tank (T). A valve (20) is interposed in the passage and controls fuel flow through the body. A flexible bellows (80) fits over the spout with the outer end (72) thereof sealingly engaging an inlet (I) of the tank to prevent fuel vapors from escaping into the atmosphere. A control apparatus is responsive to movement of the bellows when the spout is inserted into the tank to open the valve, and to removal of the spout from the tank to close the valve. An apparatus (176) is responsive to the vapor pressure within the tank to effect closing of the valve when an overpressure condition occurs thereby to prevent vapor from escaping into the atmosphere. The apparatus includes first and second pivotally connected levers (132, 136) one of which moves in response to movement of the bellows and the other of which moves in response to the vapor pressure reaching a predetermined level indicative of the tank being substantially full to close the valve and prevent vapors from escaping.

摘要:
The invention relates to a Fuelling gun which avoid "after-drip" when used. The fuelling gun comprises an outlet pipe (2) and a valve (3) which is disposed at the free end (10) of the outlet pipe (2). As a result the fuel within the outlet pipe (2) cannot drop when the fuelling gun is extracted from the fuel tank.
摘要:
A fuel filling nozzle assembly (3) for providing fuel to a fuel tank (33) comprising: a nozzle bore (18) within which is housed first (20) and second (22) valves located so as to provide respective exit and entry ports to the nozzle bore; a valve control assembly, comprising a telescopic bolt assembly (21) attached at opposite ends to the first and second valves, the valve control assembly being moveable relative to the nozzle bore, and a nozzle activation assembly wherein the nozzle activation assembly acts on the valve control assembly so as to open the first and second valves consecutively, thereby providing a fuel flow through the nozzle bore.
摘要:
A vapour recovery nozzle (10) is disclosed in which the main body (11) of the nozzle has the vapour passage (36) located above the fluid passage (16), so that the fluid valve (22) is separated from the top of the nozzle by the vapour passage. Thus the valve may only be removed through the bottom of the nozzle by removing the trigger mechanism (73) and removing the vacuum tripping mechanism (81) which is also connected to the trigger mechanism. Removal of the tripping mechanism is also made easily determinable by the use of a soft aluminium seal (123) over the top opening of the trigger mechanism. The tripping mechanism is responsive to displacement of the vapour recovery shroud (30) to prevent dispensing fuel unless the nozzle is in the fill tank. Other improvements include an improved trigger mechanism having a camming surface (80) to engage the stem (55) of the fluid valve (22).

A modular dispensing nozzle particularly adapted for dispensing gasoline and constructed for easy repair and low pressure drop is provided with a novel automatic shut-off mechanism which terminates fluid flow through the nozzle in response to predetermined conditions.
摘要:
An automatically closing control valve for liquids which includes entry (3') and exit (4') apertures and an internal chamber (5) in which a piston (6) that opens and closes the entry (3') and exit (4') apertures slides. The valve (1) has springs (10, 20) that closes the piston (6), mechanical or pneumatic means (11, 22, 23) to keep the piston (6) open and a monitoring probe (12, 26). The probe (12, 26) communicates with pneumatic means (15, 16, 28, 29) that keep the piston (6) in an opened position and that operate the springs (10, 20) that returns the piston (6) upon reaching maximum level. The aperture (4') is connected to the nozzle (4'') shaped as a Venturi tube, which creates the vacuum to activate the pneumatic means (15, 28).
摘要:
A pre-pay fuel system having a fuel nozzle (1) with automatic cutoff provisions (12, 18, 32) when a full tank exists or unwanted tank pressure conditions are detected is also provided with a low fuel pressure controlled cutoff (22, 44). The fuel pressure cutoff (22, 44) allows rapid response to permit fuel flow when high pressure exists in the nozzle (1) and provides a nozzle flow cutoff after a predetermined time delay when low fuel pressure exists in the nozzle (1).
