Abstract
Description
- The present invention relates to a gun for dispensing gaseous fuel, in particular gaseous fuel for motor vehicles according to the preamble of appended
claim 1. - Such a gun is known, for example, from document WO-88/01601.
- 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.
- To maintain the coupling means on the filler pipe while the fuel is dispensed through the head, such dispensing guns are provided with means for locking the aforesaid coupling in the operative dispensing position.
- In a known dispensing gun, 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.
- To unlock the pivot pin from the projection, 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. By maintaining the pushbutton pressed and the pivot pin in the disengaged position, the dispensing lever can thus be moved in order to return the coupling means to the non operative position.
- Therefore, at the end of the fuel dispensing operation, to return the coupling means to the initial position, a user must act on the unlocking pushbutton and simultaneously move the lever in order to disengage the pivot pin from the corresponding 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.
- Very often, the user is not able to perform the locking operation with one hand, because the lever must be moved forward whilst maintaining the unlocking pushbutton pressed.
- Since the fuel dispensing lever exerts a certain pressure on the locking pivot pin, the unlocking pushbutton is rather hard to press.
- Moreover, 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. In this situation 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.
- From document WO-88/01601, which is considered the closest prior art, is known a dispensing nozzle for liquidified petroleum gas having an actuating lever that is held in the open position by a latch mounted on pin in the guard of the nozzle. The latch is biased by a spring in an unlocked position for the actuating lever and the hooked end of the latch engages latch pin in the end of the lever.
- From document DE-1226 904 B is known a gun for dispensing liquid fuel with a locking latch pivoted on the actuating lever and a notch on the gun guard, the locking latch, which has a hook cooperating with the notch, is free inserted in the actuating lever and is removable.
- The aim of the present invention is to provide an enhanced gaseous 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.
- In accordance with the present invention, a fuel dispensing gun as specified in
claim 1 is presented. - The depend claims refer to preferred and advantageous embodiments of the invention.
- Embodiments of the present invention, purely by way of non limiting examples, are illustrated in the detailed description that follows, made with reference to the accompanying drawings, in which:
- Figure 1 shows the dispensing gun in a first preferred embodiment in a lateral view in which the coupling means are in a non operative position;
- Figures 1a and 1b show some constructive details of the dispensing gun of Figure 1;
- Figure 2 shows a cross section of the dispensing gun of Figure 1 associated to a filler pipe of a tank in a locked position of the coupling means;
- Figure 3 shows the dispensing gun of Figure 2 in the initial phase of unlocking of the coupling means from the filler pipe;
- Figure 4 shows a cross section of the dispensing gun in a second preferred embodiment associated with a filler pipe of a tank;
- Figure 5 shows the dispensing gun of Figure 4 in the initial phase of unlocking of the coupling means from the filler pipe.
- In accordance with the figures of the accompanying drawings, the
reference number 1 indicates a gun for dispensing fluid fuel, in particular gaseous fluid, into a tank provided with afiller pipe 2, such as the tank of a motor vehicle (not shown). - The
gun 1 comprises abody 3 of substantially elongated cylindrical shape and agrip 4 having anupper end 4s associated with therear portion 3b of thebody 3 itself. - Inside the
grip 4 is obtained aconduit 5 for supplying the fuel, which ends, at itsfirst end 5i, with a coupling for a pipe feeding gaseous fuel from a dispensing device (not shown). - The
conduit 5 communicates, in correspondence with asecond end 5s, with achannel 6 for the passage of fuel obtained internally to thebody 3 and able to be shut off by means of avalve 7. - In correspondence with the
front portion 3a of thebody 3 are positionedmeans 8 for coupling thepiston 1 on thefiller 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 alever 9 able to oscillate about anaxis 10. - In the illustrated embodiments, the coupling means 8 are constituted by a
sleeve 11 able to slide on thebody 3 of thegun 1 and provided witharms 12 presenting atooth 13 at one end. Thearms 12 are able to move radially in such a way that theteeth 13 achieve the coupling with thefiller pipe 2. - The dispensing
gun 1 is further provided withmeans 14 for locking the coupling means 8 in the operative fuel dispensing position, which means comprise a retainingelement 15 integral with therear portion 3b of thebody 3 of thegun 1 in proximity to thelever 9. - According to the present invention, the locking means 14 comprise a
latching element 16 pivotally engaged on thelever 9 and able to oscillate at least from a position of engagement with the retainingelement 15 to lock the coupling means 8 in the operative position to a configuration of disengagement from the retainingelement 15 itself to return the coupling means 8 to the non operative position. - Advantageously, the locking means 14 comprise
elastic means 17, for instance a spring, interposed between thelever 9 and thelatching element 16 to maintain thelatching element 16 stably in the configuration of engagement with theretaining element 15. - In the embodiment illustrated in the figures, the
retaining element 15 is constituted by abar element 18 substantially parallel to theaxis 10 of thelever 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 acontoured projection 19 able to be engaged with thebar element 18 in such a way as to ensure the locking in the operative position. - To facilitate the latching, the
contoured projection 19 has aportion 19a inclined towards thebar element 18. - More specifically, the angle α of the
inclined portion 19a must be between 65 degrees and 25 degrees and preferably be 50 degrees; the angle a is measured relative to a plane P passing between the fulcrum axis of thelatching element 16 and tangential inferiorly to the surface of thebar element 18 in the area of the part 18a. - The particular inclination of the
portion 19a favours an easy sliding of thelatching element 16 on thebar element 18, in such a way as to avoid jamming and sticking when thelever 9 for dispensing the fuel is operated. - The
latching element 16 further comprises aninner portion 19b that presents a surface whose diameter is substantially similar to that of thebar element 18 and which extends for an arc that insists on an angle β - measured at the centre of the arc - greater than 90 degrees, and preferably with an angle β of 120 degrees. - Also the particular measure of this angle P favours a secure latching of the
element 16 to thebar element 18 and at the same time allows an easy unlatching of theelement 16 at the end of the fuel dispensing operation when thelever 9 must be returned to the position where fuel dispensing is shut off. - At a second end, the
latching element 16 has agrip element 20 substantially parallel to thelever 9, to impart the rotation to thelatching 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). - According to the embodiment shown in the Figures, the
lever 9 has a fork shapedupper end 21 positioned externally relative to thebody 3 of thegun 1 inside grooves obtained on thecoupling sleeve 11. - The
fork 21 is pivotally engaged in proximity to theupper exterior surface 3s of thebody 3 of the dispensinggun 1, enabling the displacement of thelever 9 in advanced position to unlock the coupling means 8 by the application of a reduced force. - Advantageously, the
lever 9 has aseat 22 for housing thelatching element 16, situated in correspondence with alower end 21 i of thefork 21, in such a way as to diminish the size of the locking means. - In use, to carry out the fuel dispensing operation, bringing the
lever 9 towards thegrip 4, thefork 21 moves the coupling means 8 towards thefiller pipe 2 making thesleeve 11 slide on thebody 3 of thegun 1. - When the
projection 19 of thelatching element 16 comes in contact with thebar element 18, the latter slides on theinclined portion 19a of theprojection 19 so that thelatching element 16 compresses thespring 17. - The displacement of the
latching element 16 relative to thebar element 18 occurs automatically thanks to the particular angle of theinclined portion 19a and thanks to the particular shape of the part 18a of thebar element 18 which comes in contact with the aforesaidinclined portion 19a. - Continuing the displacement of the
lever 9 in the direction of thegrip 4, theprojection 19 is first brought to the position of engagement with thebar element 18 and then maintained in the same position by thespring 17. - In this way, the displacement of the
lever 9 is stopped and the coupling means 8 are locked on thefiller pipe 2 in the operative fuel dispensing position. - To accomplish the unlocking operation, as shown in Figure 3, one acts on the
grip element 20 making it rotate in the direction of thebody 3 of thegun 1, in such a way as to disengage theprojection 19 of thelatching element 16 from thebar element 18. Thelever 9 can then be easily moved away from thegrip 4 so that thefork 21 returns the coupling means 8 to the initial non operative position. - In the embodiment of Figure 4, to accomplish the unlocking operation, one acts on the
grip element 20 in the direction of thegrip 4 in such a way as to make thelatching element 16 rotate towards thebody 3 of thegun 1 disengaging theprojection 19 from the bar element 18 (Figure 5). - 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.
- To unlock the lever, it is sufficient to exert a simple pressure on the grip element in such a way as to cause it to rotate and thus disengage the latching element from the retaining lever.
- Once the latching element is disengaged, the lever automatically moves to the advanced position, returning the coupling means to the non operative position at the end of the dispensing operation.
- It is therefore sufficient for a user to act on a single element to accomplish the unlocking operation, with no need to carry out different operations in succession, which are often known only to specialised personnel.
- The danger that a user may disengage the gun from the tank when the coupling means are still in the operative fuel dispensing position is therefore eliminated. Moreover, the disposition of the fulcrum of the lever in proximity to the upper surface of the body of the gun allows to move the lever to the locking position using less force, and thus making the refuelling operation easier.
