Problems solved by technology

Although a reliable connection possibility is thus obtained, the handling of this connector is relatively adaptable, especially for gas station users who wish to use a common refueling lance, because in addition to plugging in the connector, The control handle must also be operated, so one-handed operation is almost impossible

Embodiment Construction

[0012] In FIG. 1 there is shown an embodiment of a quick connector 10 connected to an internal connection fitting 30 (see FIG. 2). The quick connector 10 has a tubular, curved housing 11 to interconnect the housing parts, wherein the right side in the figure is taken as an inlet 12 and the left end as an outlet 13 for the further transmission of the transferred fluid into the inner Connect the connector 30. The inlet 12 to the housing 11 has a connection adapter 14 which can be connected to a hose or a pipe for feeding in the fluid to be conveyed. In this case, the connection adapter 14 can be adapted to the fluid to be transported, in particular to the desired input angles, flow cross-sections, etc.

[0013] The end face opposite to the connection adapter 14, namely the outlet 13, is preferably provided as a plurality of tubularly arranged, slightly elongated clamping jaws 15 as clamping elements (see FIG. It is flared radially outwards just before being plugged onto the in...

Abstract

The aim of the invention is to create a simple and reliable locking device for a quick-action connection coupling for transferring gaseous and/or liquid fluids, especially for refuelling vehicles. Said device comprises a hand lever (50) for actuating a valve and a lock which is positioned on the end side thereof and engages with a hand grip (45) in the refuelling position. To this end, an unlocking lever (46) which can be pivoted on the hand grip (45) is mounted adjacent to the end region of the hand lever (50). The unlocking lever (46) comprises at least one, preferably two laterally protruding journals (47), arranged inside the hand grip (45), especially for simple handling.

Description

technical field [0001] The invention relates to a locking device for a quick coupling according to the features of the preamble of claim 1 . Background technique [0002] Reliable and fast connectability for refueling vehicles is to be achieved in such quick couplings (eg according to DE 33 13 258). Particularly important here is the simple and smooth operability of the quick couplings, so that they can be handled smoothly even under unfavorable conditions or by persons with little technical expertise. In order to lock a handle as used here, a detent mechanism on an arcuate handle is disclosed in the above-mentioned document, but relatively high effort is required to unlock the detent mechanism. [0003] In addition, in the applicant's patent document WO 98 / 04866, a quick connector is disclosed, in which a plurality of valves are arranged to ensure a reliable connection until the communication is completely established. For this reason, the valves are connected in a predet...
