Definitions

  • the invention relates to an actuating device for a quick-connect coupling for the transmission of gaseous and / or liquid fluids according to the preamble features of claim 1, from the DE 203 05 357 U1 are known.
  • a secure and fast connectivity for transmitting a fluid from a pressure source for example, from a gas tank of a gas station for vehicle refueling to be achieved.
  • a pressure source for example, from a gas tank of a gas station for vehicle refueling to be achieved.
  • a secure and fast connectivity for transmitting a fluid from a pressure source for example, from a gas tank of a gas station for vehicle refueling to be achieved.
  • a pressure source for example, from a gas tank of a gas station for vehicle refueling
  • a well-known quick-connect coupling is in the WO 98/04866 described in the applicant, wherein the quick-connect coupling has a housing with an inlet and an outlet valve, and a plurality of valves are provided to ensure a secure seal of the quick-connect coupling until complete connection.
  • These valves are switched after applying the quick connector in a particular predetermined order, first by the pushing out of the quick connector to a connection nipple the exhaust valve is opened, then upon further movement of a control lever as an actuator, the collets are closed and finally the inlet valve is opened.
  • the control lever is in this case via an eccentric shaft with the sliding sleeve for the application of the collets and with a central sealing piston in engagement, which releases the fluid inlet after the connection of the plug-in coupling.
  • the invention has for its object to provide an actuator for a quick-connect coupling of the type mentioned above, which allows a simple and simple design a safe and very easy to use.
  • the proposed actuator is characterized by a particularly simple operation, which is also very safe.
  • the connection or the release of the quick-connect coupling is carried out as in a usual petrol refueling nozzle, namely by simple manual one-handed operation. This is particularly important for reasons of market acceptance of natural gas filling stations, since customers have virtually no need to change to safely connect or disconnect this connection coupling during the filling process.
  • the proposed actuator is suitable for various terminal types or nipples.
  • a hand lever known from nozzles, so that in a simple manner, a safe and fast one-handed operation of the quick-connect coupling is possible, the tanker of the operating sequence is basically known.
  • Fig. 1 is a preferred embodiment of an actuating device 1 for a quick-connect coupling 10 for connection to a connection nipple 30 (see. Fig. 2 ).
  • the quick-connect coupling 10 has a tubular, cranked housing 11 or interconnected housing parts, in which case the right side as an inlet 12 and the left side serves as an outlet 13 for the forwarding of the fluid to be transferred to the connection nipple 30.
  • the inlet 12 to the housing 11 has a connection adapter 14 which can be connected to a hose or a pipe for supplying the fluid to be transferred ,
  • the connection adapter 14 can be designed in this case in adaptation to the fluid to be transferred, in particular to the respective desired feed angle, passage cross sections, etc.
  • connection adapter 14 opposite end face, namely the outlet 13 a plurality of tube-shaped, elongated collets 15 are provided as locking elements (see. Fig. 2 ), which are spread radially outwards just before plugging onto the connecting nipple 30, as is shown for example in US Pat WO-A-93/20378 the applicant is shown.
  • the elongated collets 15, generally three or six, are hooked at their right end here to an annular groove 11 a of the housing 11 and thereby biased by an annular spring 16, so that the collets 15 are spread radially outwards.
  • the collets 15 each corresponding to the connection nipple 30 formed positive engagement profiles 17.
  • an outer sliding sleeve 18 is provided, which is mounted on the cylindrical outer surface of the housing 11 in the manner of a rotary union and can be axially advanced with the actuator 1 in the direction of the connecting nipple 30, as will be described below.
  • the sliding sleeve 18 in this case has an extension 20, which allows the actuator 1 in the central region of the quick connector 10 toward the axial displacement of the sliding sleeve 18, whereby the collets 15 are locked by the wrapper by means of the sliding sleeve 18 in the connection position.
  • this outlet-side structural unit is rotatable relative to the middle switching or actuating unit in order to connect the coupling 10 in any desired rotational position.
  • a sealing piston 22 is guided on the inner surface of the housing 11, which is located towards the outlet 13, and bears against a sealing surface of the connecting nipple 30.
  • the sealing piston 22 is sealed relative to the collets 15 with a plurality of sealing rings 24 inserted at the front end of the housing 11, so that the gaseous and / or liquid fluid flowing along the central axis of the quick-connect coupling 10 can not escape to the outside.
  • the outlet valve 25 is in this case acted upon by a compression spring 28 which is guided in the housing 11.
  • this outlet valve 25 it is ensured that the fluid supplied through the connection adapter 14 can not escape until shortly before the connection of the quick-connect coupling 10 to the connection nipple 14, even when the connection cock is open at the refueling system.
  • the outlet valve 25 is axially displaced when plugging the quick connector 10 on the connecting nipple 30 from the sealing piston 22 and in this case the exhaust valve 25 is opened. In this case, however, an inlet valve 35 of the quick-connect coupling 10 is still closed, which is then opened only in the further sequence by the actuating device 1 or an associated slide 41, as described below.
  • the sliding ring 40 is acted upon by a lever mechanism 42, which also controls the slide 41.
  • the slider 41 is guided in this case in the housing 11 and acted upon by a compression spring.
  • the sliding ring 40 is acted upon by a pivot lever 43, whereby it is displaceable from the open position to the connection or locking position.
  • the pivot lever 43 is thereby manually by pulling up a hand lever 50 (within a hand strap 45) along the end face of the sliding ring 40 pivoted downward, whereby at the same time a stop lever 44 of the hand lever 50 on the hand strap 45 engages.
  • a stepped lock 44 ' is provided in order to lock the hand lever 50 in this refueling position.
  • the latch 44 ' is released by pressing the stop lever 44, so that then the hand lever 50 about its axis 51 (here clockwise) can move downwards (see. Fig. 4 ), wherein the components coupled thereto of the lever mechanism 42 follow, so the pivot lever 43 is pivoted with its ramp-like front surface 43 'along the sliding ring 40 back up, as from the comparison between 3 and 4 is apparent.
  • the lever mechanism 42 also acts on a connected to the slider 41 and roller 46 has two superimposed levers 47 and 47 ', the lower ends are connected via a common pin 48' as a joint with the hand lever 50.
  • the in Fig. 3 slightly smaller drawn, outer lever 47 'is hingedly connected at its upper end by a bolt 48 with the pivot lever 43 so that this at Operating the hand lever 50 in the drawing plane ( Fig. 1 and 3 ) is pivoted to move the sliding ring 40 axially.
  • the inner lever 47 is moved in a groove on the side surface of the housing 11 in the manner of a link 49 upwards to act with a wedge surface 47 a, the roller 46 in the axial direction.
  • the associated slider 41 is pressed against the inlet valve 35, so that it is moved to the open position.
  • the slider 41 is in this case by a compression spring (see. Three-dimensional representation in Fig. 4 ), so that the roller 46 bears against the wedge surface 47a of the inner lever 47.
  • the slide 41 is not only provided for controlled opening of the inlet valve 35, but also for actuating a vent valve 60 arranged therebetween. This leads via a bore 61 arranged in the housing 11 (cf. Fig. 2 ) to a vent port 70 so that gas or fluid remaining in the port coupler 10 can be recirculated.
  • This venting valve 60 which is likewise co-actuated by the slide 41, also facilitates the uncoupling, as a result of which a defined pressure reduction can take place.
  • each such lever mechanism 42 is arranged in a symmetrical manner on both sides of the flattened side surfaces of the central region of the housing 11 and via the (common) pin 48 'on the hand lever 50 is articulated. This results in a uniform loading of the sliding ring 40.
  • these two-sided lever mechanisms 42 by an in Fig. 3 indicated cover 81 covered to prevent contamination or injury. This is followed by an in Fig. 2 Sheath 80 shown, which also serves as a handle in the central region.
  • the stop lever 44 on the profiled hand lever 50 is slightly withdrawn by hand. After a short Verschwenkweg first hand lever 50 (down towards) is released, which ultimately the sliding sleeve 18 is withdrawn.
  • the collets 15 can again spread radially outward, wherein simultaneously the slider 41 is moved over the lever mechanism 42 here to the left and previously the pivot lever 43 has been pivoted up to follow the sliding ring 40 axially here to the right.
  • the exhaust valve 25 is also closed in the manner of a sequential control.
  • the pivot lever 43 together with the force-translating lever mechanism 42 also allows a power-saving coupling of the quick connector 10 to the connection nipple 30, the collets 15 are closed only when the sealing contact is ensured because the open position of the collets 15 (or other locking elements, such as balls ) is maintained until the axial position of the sealing piston 22 and the sliding ring 40 in direct order, the open position of the collets 15 is released to make the connection.
  • Fig. 4 is a three-dimensional representation too Fig. 3 shown, wherein corresponding components with the same reference numerals as in Fig. 1 and 2 are designated.
  • the lever mechanism 42 essential here has the same structure, wherein the slide 41 and slide ring 40 operated thereby are shown schematically. By the axial movement of the slide 41 (here to the right) the gas passage is released and by the movement of the sliding ring 40 (here to the left), the outlet valve 25 is opened in a defined sequence, as described above.
