Definitions

  • the invention relates to a full hose nozzle for filling liquids into containers, for. B. tanks of motor vehicles and for automatically closing the spigot when the container is full, which consists of a housing which is equipped with an inlet connector and an outlet pipe, a flow valve arranged in the housing and operable with a hand lever for controlling the flow of liquid from the inlet connector to the outlet pipe and consists of a switching device which is connected via a pressure channel to the mouth of the outlet pipe, closes the flow valve depending on the pressure prevailing in the pressure channel and has a plunger-shaped switching insert.
  • Such a nozzle is known from EP-OS 0 239 193.
  • the switching device is arranged behind the flow valve regulating the liquid flow and a spring-loaded check valve is provided in the connection area between the housing and the outlet pipe.
  • This check valve which is required to keep all the flow-through spaces of the switched-off nozzle apart from the outlet pipe filled with liquid, increases not only the weight, but also the dimensions and the manufacturing costs of the nozzle.
  • the object of the invention is now to develop an inexpensive to manufacture full hose nozzle of light weight and small volume.
  • the switching device is provided in the housing between the inlet connector and the flow valve, which closes against the flow of the liquid to be dispensed, and on the handle part opposite the end of the hand lever articulated on the housing, there is a switching lever is pivotally held, one end of which engages with the valve rod of the flow valve and the other end of which is supported in the articulation point of the hand lever.
  • the arrangement and design of the flow valve which is provided according to the invention in the direction of flow of the liquid to be dispensed behind the switching device and closes against the flow of this liquid, means that a check valve that prevents the liquid from escaping when the nozzle is switched off is dispensed with in the transition region between the nozzle valve housing and the outlet pipe will.
  • the nozzle can not only be manufactured inexpensively with smaller dimensions. It also reduces its weight, also its weight, due to the small volume of liquid in the nozzle, which makes its handling z. B. facilitated when refueling motor vehicles.
  • the closing direction of the flow valve against the flow according to the invention also prevents pressure surges or impacts in the supply system of the nozzle, in particular when it is automatically switched off.
  • the actuation of the flow valve with one end of the hand lever designed as a two-armed lever via a switching lever pivotally held at this end, one end of which engages with the valve rod of the flow valve and the other end of which is supported in the articulation point of the hand lever also offers the advantage that that both the selection of the articulation point of the shift lever on the hand lever and the articulation point of the hand lever on the housing not only reduce the forces to be absorbed by the switching device and thus their dimensions.
  • the switch-off behavior of the nozzle valve can also be easily adapted to the composition of the liquid to be dispensed (petrol, diesel).
  • the nozzle valve In order to recover the gases displaced from the same when filling a container, in an expedient development of the nozzle valve according to the invention, its outlet pipe is surrounded by a bellows, one end of which is arranged gas-tight on the housing and the other end in the region of the mouth of the outlet pipe with the filler neck of the Filling container cooperating sealing element, wherein the annular channel between the outlet pipe and bellows is connected to a gas return channel formed on the inlet port.
  • the bellows is expediently operatively connected to a slide valve via a push rod to interrupt and / or prevent the dispensing of liquid from the nozzle in the event of insufficient insertion of the outlet pipe into the filler neck of the container to be filled and thus the lack of a gas-tight transition between the filler neck and the bellows , which changes the position of a permanent magnet in the housing, which controls a valve ball to interrupt the connecting channel between the switching device and the pressure channel in the outlet pipe for actuating the switching device.
  • the permanent magnet can be further held on a membrane influencing its position in the housing, which delimits a pressure chamber connected to the annular channel between the bellows and the outlet pipe in order to control the valve ball in the event of excessive pressure in the gas recirculation system in such a way that the switching device releases liquid prevents.
  • valve 1 consists of a housing 40, from the inlet connector 1 of which the liquid to be dispensed flows through a liquid channel 39 to the mouth 2 of an outlet pipe 17 held on the housing 40.
  • the liquid flow is interrupted or regulated by valve body 13 of a flow valve 41.
  • the valve body 3 attached to a valve rod 13 is held in the closed position by valve springs 14 and 15 and a pressure holding spring 16 and closes against the flow.
  • a switching device 42 is further provided in the housing 40, which has a conical needle 4 guided in a plunger-shaped switching insert 5, which presses the switching balls provided in a cage of the switching insert 5 against the wall of a locking sleeve 7 and thus the switching insert 5 compared to the locking sleeve 7 creates connection.
  • a hand lever 9 is pivotally held with two bolts 8 (FIG. 2).
  • a shift lever 11 At the handle part 9 opposite end of the hand lever 9 is pivoted with a bolt 12, a shift lever 11, one end of which engages with the valve rod 13 and the other end of which is in alignment with the bolt 8 bolt 10 between the legs of the forked end of the Switch insert 5 supports.
  • the free or head end of the needle 4 is connected to a membrane 25 which closes a vacuum chamber 43, in which there is a membrane spring 26 which presses the needle 4 in the direction of the switching insert 5.
  • the vacuum chamber 43 is connected via bores 24, 20 and 21 and the valve channel 18 in the valve seat 19 of the flow valve 41 to a pressure channel 22 in the outlet pipe.
  • the pressure channel 22 opens into an opening 23 in the outlet pipe 17.
  • a bellows 29 Arranged around the outlet pipe 17 is a bellows 29 which is fastened at one end to the housing 40 and the other end of which carries an annular sealing element 28 in the region of the mouth 2 of the outlet pipe 17.
  • the annular channel 44 between the outlet connector 17 and the bellows 29 is connected to the inlet connector 1 via a gas return channel 45 in the housing 40.
  • a push rod 31 On the bellows 29 a push rod 31 is also held, which acts on a slide valve 30 of a gas recirculation device 46, which comprises a permanent magnet 32 biased in the direction of a valve ball 34 with a spring 33.
  • the valve ball 34 closes the connection, formed as a nozzle 35, between the bores 20 and 21 in the housing 40, which is controlled by the permanent magnet 32 by changing its distance from the valve ball 34 against the force of the spring 33 from the slide valve 30.
  • a membrane 37 is also held on the permanent magnet 32, which forms a pressure chamber 47 with a housing recess in which the slide valve 30 and the permanent magnet 32 are arranged, said pressure chamber being connected to the annular channel 44 via a bore 36.
  • the function of the full hose nozzle shown is briefly explained below:
  • the liquid flowing through the liquid channel 39 from the inlet port to the mouth 2 is interrupted or regulated by the flow valve 41.
  • this valve 41 can only be opened when the switching device 42 is engaged, the needle 4 pressing the switching balls 6 against the wall of the locking sleeve 7 and thereby fixing the switching insert 5 in the locking sleeve 7 (FIGS. 3A and 3B).
  • the shift lever 11 which is connected to the hand lever 9 via the bolt 12, is moved around the pivot point formed by the bolt 10 and can counteract when the switching device is engaged act a force F (Fig. 3B), whereby the valve rod 13 is moved against the force of the valve springs 14 and 15 away from the valve body 3.
  • the pressure of the liquid to be dispensed now opens the valve body 3 against the force of the pressure-holding spring 16, so that liquid can be dispensed via the outlet pipe 17.
  • the flow of the liquid creates a negative pressure in the valve channel 18 of the valve seat 19, which balances itself with the atmosphere via the bores 20 and 21 and the pressure channel 22 and the opening 23.
  • valve rod 13 is pushed by the valve springs 14 and 15 into the closed position of the flow valve 41, whereby the shift lever 11 is rotated about the bolt 12 and the liquid dispensing is automatically interrupted.
  • the position of the hand lever 9 held on the locking sleeve 7 remains unaffected by this.
  • the hand lever 9 If the hand lever 9 is released after such a switch-off of the dispensing valve, it is transferred together with the switching lever 11 and the switching insert 5 by the return spring 27 of the switching device 42 into the starting position (FIG. 3A). At the same time, the needle 4 and the diaphragm 25 are brought into the starting position by the diaphragm spring 26 in order to lock the switching device 42 with the switching balls 6, so that liquid can be dispensed again with the nozzle valve by actuating the hand lever 9.
  • the prerequisite for the liquid delivery is the proper insertion of the outlet pipe 17 into the filler neck of a container, not shown, and thereby the establishment of a gas-tight connection between the filler neck and the bellows 29 with the sealing element 28.
  • the switching device shown in FIGS. 4A, 4B and 4C essentially differs from the switching device 42 described above in connection with FIGS. 3A, 3B and 3C only in that the hand lever 9 'is not on the locking sleeve 7' but on the housing fork 48 is held and the locking sleeve 7 'is displaceable relative to the fixed switching insert 5'.
  • the shift lever 11' which is connected to the hand lever 9 'via the bolt 12', is moved around the bolt 8 'and can act against a force F at the point of engagement when the switching device is engaged.
