Definitions

  • the invention relates to a locking device for a quick-connect coupling according to the preamble features of claim 1.
  • a Schnellan gleichkuppiung is also shown, wherein a plurality of valves are provided to ensure a secure connection until the complete production of the compound. These valves are switched after applying the Schnellan gleichkuppiung in a certain predetermined order, first 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 power requirement is still relatively high, which also applies to the locking and unlocking. Although this creates a secure connection option, the handling of this clutch is still getting used to, especially for gas station customers who expect a conventional fuel nozzle, since in addition to attaching the clutch, the actuation of the control lever is required, so that a one-handed operation is hardly possible.
  • the invention has for its object to provide a locking device for a Schnellan gleichkuppiung of the type mentioned above, which allows a simple, safe and very simple and power-saving handling with a simple structure.
  • This object is achieved by a locking device according to the features of claim 1.
  • Preferred developments of the invention are the subject of the dependent claims.
  • the proposed locking device 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 with a corresponding unlocking similar to 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 unlock this coupling coupling after the filling process and uncouple.
  • the proposed locking device is suitable for various connections or nipples.
  • the handrail release lever which acts on the similarly shaped locking lever at the end of the hand lever, a power-saving and safe unlocking is achieved in a kind of one-handed operation.
  • the operator need not or hardly be implemented, especially when one or preferably two pins abkragen laterally from the release lever.
  • the unlocking of the locking element for both right and left-handed is readily possible.
  • the hand lever of nozzles is known per se, so that in a simple way, a safe and fast one-hand operation of the quick connector is made possible, the tanker of the operating sequence is basically known.
  • 1 is a side view of a quick-connect coupling for a tank connection.
  • FIG. 2 a representation of the quick-connect coupling according to FIG. 1 in longitudinal section
  • Fig. 3 is an enlarged view of the transition region A in Fig. 2;
  • FIG. 4 is a perspective view of FIG. 3rd
  • the quick connector 10 has a tubular, cranked housing 11 or interconnected housing parts, here the right side serves as an inlet 12 and the left side 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 On the end face opposite the connection adapter 14, namely the outlet 13, a plurality of oblong collets 15 arranged in tube form are preferably provided as locking elements (see Fig. 2), which are spread radially outwards shortly before being placed on the connection nipple 30, such as this is shown for example in WO-A-93/20378 of the applicant.
  • the elongated collets 15, generally three or six, are hooked at their right end here to an annular groove 11a of the housing 11 and biased by an annular spring 16. At the here left end on the inwardly cranked surface, the collets 15 each adapted to the connection nipple 30 engagement profiles 17.
  • a sliding sleeve 18 which is mounted on the cylindrical outer surface of the housing 11 in the manner of a rotary feedthrough and can be axially advanced with an 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 in the connection position.
  • a sealing piston 22 is guided on the inner surface of the housing 11 located towards the outlet 13. This is sealed with a plurality of sealing rings 24 used 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.
  • exhaust valve 25 is also a centrally mounted in the housing 11 exhaust valve 25.
  • the outlet valve 25 is in this case acted upon by a compression spring 28 which is guided in the housing 11.
  • the outlet valve 25 ensures that until shortly before the Connection of the quick connector 10 to the nipple 30 the fluid supplied through the connection adapter 14 can not escape even when the connection tap on the refueling system is open.
  • the outlet valve 25 is when attaching the quick-connect coupling 10 on the Rannippe! 30 axially displaced by the sealing piston 22 and in this case the outlet valve 25 is opened. 'It should, however, still an intake valve 35 of the quick connector coupling 10 is closed, which is then opened only in the further sequence of the operating device 1 and an associated slide 41 as described below.
  • a sliding ring 40 is also guided, which is acted upon by a lever mechanism 42, which also controls the above-mentioned slider 41.
  • the lever mechanism 42 includes a hand lever 50 (within a hand strap 45) which engages after pulling up or pivoting about the axis 51 in the position shown here with a locking lever 44 at the end of the hand lever 50 on the hand strap 45.
  • a locking in the form of a locking bolt 44 ' is provided to lock the hand lever 50 in this locked refueling position.
  • unlocking lever 46 which is shown in Figs. 3 and 4 enlarged.
  • Fig. 3 the end portion of the hand lever 50 is shown enlarged, on which the locking lever 44 is pivotally mounted and when pulling up under spring pressure on the locking bolt 44 'engages.
  • the angle-shaped unlocking lever 46 is renewably mounted, namely on the upper leg of a clamp 49 (see also FIG. 4).
  • two pins 47 are provided, on which the release lever 46 (by grasping with two fingers or only by pressure with a finger / thumb) can be pivoted clockwise.
  • the previously latched locking lever 44 is pressed out of its latching on the locking bolt 44 ', which is preferably formed by the lower leg of the bracket 49.
  • the hand lever 50 can be pivoted within the hand bracket 45 down to finally remove the clutch 10.
  • the Entriegeiungshebel 46 is conveniently located on the pin 47 and well protected in the handrail 45 stored and space-saving integrated therein.
  • the above-mentioned bracket 49 fulfills a dual purpose, namely on the one hand, the storage of the unlocking lever 46 and on the other the formation of the locking bolt 44 ', on which the locking lever 44 engages when pulling the hand lever and thus locks the lever mechanism.
  • the laterally slightly projecting pins 47 are well protected in the transition region from the handrail 45 to the handle or its casing 80, but still reach well from the fingers on the casing 80, so that the release lever 46 can be pivoted in the manner of a one-hand operation, at the end of the refueling process to release the lock 44/44 '.
  • the slide 41 serves not only for controlled opening of the inlet valve 35 but also for actuation of a venting valve 60 arranged therebetween.
  • 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.
  • this can not only be angled or bent as in this case, but also bent or straight, provided that with these dimensions of the release lever 46, the essential force translation of the manual force (at the pin 47) is achieved to the Lock lever 44 with the least possible effort to bring out of the locking engagement. So wedge surfaces or ramps can be beneficial to achieve a large power transmission.
  • This translation is also influenced by the lengths of the lever on the release lever 46 (distance between pivot point and point) to release the quick release coupling 10 and thus the return to the connection position the locking lever 44 at the end of the hand lever .50 as effortlessly released from the locking engagement , After a short Verschwenkweg thus first the hand lever 50 is released (downwards), which ultimately the sliding sleeve 18 is withdrawn. Thus, the collets 15 can again radially outward spread open to let follow the sliding ring 40 axially to the right here. Before thus the sealing contact between the sealing piston 22 and the connecting nipple 30 dissolves, the exhaust valve 25 is also closed in the manner of a sequential control.
