Definitions

  • the present invention relates to a gun for dispensing fuel, in particular gaseous fuel for motor vehicles.
  • Guns for dispensing gaseous fuel for motor vehicles provided with a conduit for the passage of the fluid which is dispensed through a dispensing head are known.
  • the head is able to couple with a corresponding filler pipe for the injection of the fuel, situated on the motor vehicle, and it is provided with coupling means that allow to maintain it in position on the aforesaid filler pipe.
  • the coupling means are brought from a non operative position to an operative dispensing position by means of a lever fitted with a fork.
  • such dispensing guns are provided with means for locking the aforesaid coupling in the operative dispensing position.
  • the locking means are constituted by a pivot pin, housed in a transverse seat of the lever, which must be moved to be engaged with a projection obtained on the lower surface of the body of the dispensing gun, when the lever is brought into the operative position for dispensing the gaseous fuel.
  • a pushbutton is provided which, contrasted by a spring inserted in the same lever, moves the pivot pin in such a way as to place it in a disengaged position relative to the projection.
  • This operation is not always easy to perform, in particular in service stations where the user carries out the refuelling operation by him/herself without the intervention of specialised personnel.
  • the user is not always aware of the operation of the locking means and thus limits his/her actions to pressing the pushbutton and extracting the gun from the tank of the motor vehicle without moving the lever, and thus with the coupling means still in the operative position for dispensing.
  • the conduit for the passage of the gas remains open when the gun is removed from the tank, leading to the hazard of gas leakage into the outside environment.
  • the aim of the present invention is to provide an enhanced fuel dispensing gun in which it is easy to lock and unlock the coupling with the tank filler pipe of a motor vehicle.
  • a further aim of the present invention is to provide a dispensing gun in which the locking and the unlocking operation are immediate for any user.
  • a fuel dispensing gun as specified in claim 1 is presented.
  • the reference number 1 indicates a gun for dispensing fluid fuel, in particular gaseous fluid, into a tank provided with a filler pipe 2, such as the tank of a motor vehicle (not shown).
  • the gun 1 comprises a body 3 of substantially elongated cylindrical shape and a grip 4 having an upper end 4s associated with the rear portion 3b of the body 3 itself.
  • a conduit 5 for supplying the fuel which ends, at its first end 5i, with a coupling for a pipe feeding gaseous fuel from a dispensing device (not shown).
  • the conduit 5 communicates, in correspondence with a second end 5s, with a channel 6 for the passage of fuel obtained internally to the body 3 and able to be shut off by means of a valve 7.
  • means 8 for coupling the piston 1 on the filler pipe 2 of the tank, which are moved between a first non operative position and a second operative position for dispensing the fuel by means of a lever 9 able to oscillate about an axis 10.
  • the coupling means 8 are constituted by a sleeve 11 able to slide on the body 3 of the gun 1 and provided with arms 12 presenting a tooth 13 at one end.
  • the arms 12 are able to move radially in such a way that the teeth 13 achieve the coupling with the filler pipe 2.
  • the dispensing gun 1 is further provided with means 14 for locking the coupling means 8 in the operative fuel dispensing position, which means comprise a retaining element 15 integral with the rear portion 3b of the body 3 of the gun 1 in proximity to the lever 9.
  • the locking means 14 comprise a latching element 16 pivotally engaged on the lever 9 and able to oscillate at least from a position of engagement with the retaining element 15 to lock the coupling means 8 in the operative position to a configuration of disengagement from the retaining element 15 itself to return the coupling means 8 to the non operative position.
  • the locking means 14 comprise elastic means 17, for instance a spring, interposed between the lever 9 and the latching element 16 to maintain the latching element 16 stably in the configuration of engagement with the retaining element 15.
  • the retaining element 15 is constituted by a bar element 18 substantially parallel to the axis 10 of the lever 9, in such a way as to provide a greater available surface for the latching and render the locking easier and more stable.
  • the latching element 16 presents at a first end a contoured projection 19 able to be engaged with the bar element 18 in such a way as to ensure the locking in the operative position.
  • the contoured projection 19 has a portion 19a inclined towards the bar element 18.
  • the angle ⁇ of the inclined portion 19a must be between 65 degrees and 25 degrees and preferably be 50 degrees; the angle ⁇ is measured relative to a plane P passing between the fulcrum axis of the latching element 16 and tangential inferiorly to the surface of the bar element 18 in the area of the part 18a.
  • the particular inclination of the portion 19a favours an easy sliding of the latching element 16 on the bar element 18, in such a way as to avoid jamming and sticking when the lever 9 for dispensing the fuel is operated.
  • the latching element 16 further comprises an inner portion 19b that presents a surface whose diameter is substantially similar to that of the bar element 18 and which extends for an arc that assures on an angle ⁇ - measured at the centre of the arc - greater than 90 degrees, and preferably with an angle ⁇ of 120 degrees.
  • this angle ⁇ favours a secure latching of the element 16 to the bar element 18 and at the same time allows an easy unlatching of the element 16 at the end of the fuel dispensing operation when the lever 9 must be returned to the position where fuel dispensing is shut off.
  • the latching element 16 has a grip element 20 substantially parallel to the lever 9, to impart the rotation to the latching element 16 relative to the fulcrum. In this way the distance between the point of application of the force necessary to impart the rotation and the fulcrum is increased and the force required to achieve the unlocking is decreased.
  • the grip element 20 can be oriented towards the lower portion of the gun 1 ( Figures 2 and 3), or towards the upper portion ( Figures 4 and 5).
  • the lever 9 has a fork shaped upper end 21 positioned externally relative to the body 3 of the gun 1 inside grooves obtained on the coupling sleeve 11.
  • the fork 21 is pivotally engaged in proximity to the upper exterior surface 3s of the body 3 of the dispensing gun 1, enabling the displacement of the lever 9 in advanced position to unlock the coupling means 8 by the application of a reduced force.
  • the lever 9 has a seat 22 for housing the latching element 16, situated in correspondence with a lower end 21i of the fork 21, in such a way as to diminish the size of the locking means.
  • the fork 21 moves the coupling means 8 towards the filler pipe 2 making the sleeve 11 slide on the body 3 of the gun 1.
  • the displacement of the latching element 16 relative to the bar element 18 occurs automatically thanks to the particular angle of the inclined portion 19a and thanks to the particular shape of the part 18a of the bar element 18 which comes in contact with the aforesaid inclined portion 19a.
  • the projection 19 is first brought to the position of engagement with the bar element 18 and then maintained in the same position by the spring 17.
  • the dispensing gun according to the present invention thus allows easily to achieve the locking and unlocking of the means for coupling on the tank filler pipe.
  • the lever automatically moves to the advanced position, returning the coupling means to the non operative position at the end of the dispensing operation.
