A plug-in coupling for systems involving pressurized media, where the coupling consists of two connector parts, a housing part (,) and a connector part (,). The connector part (,) can be inserted into a receiving opening (,) of the housing part (,), while it is being sealed, and when it is in a plugged-in condition, it can be locked in place and prevented from being released by means of a locking device (,). The locking device (,) includes a retaining element (,), which is supported on one side of one of the coupling parts, and which retaining element engages&mdash;while in the assembled state&mdash;a retaining groove (,) of the other coupling part by means of a form-fit or a form- and friction-fit. A release device (,) is provided in such a manner, that&mdash;starting from the assembled state&mdash;the retaining element (,) is brought into a release position by means of a further insertion of the connector part (,), in which position the retaining groove (,) is released and the connector part (,) can be removed from the receiving opening (,). The release device (,) is equipped with a sleeve-type locking bar (,), which is capable of relative movement, and which is to be used in conjunction with the retaining groove (,) in such a manner, that the retaining element (,), when it is in the release position, is brought into radial contact with a circumferential area (,) of the locking bar (,) and is thus held in the release position, and when the movement to remove the plug-in connector takes place, the retaining groove (,) is covered by the locking bar (,) and thus closed off in a radial direction from being engaged by the retaining element (,).

Plug in coupling for pressure fluid

A plug-in coupling for pressurized systems having two coupling components (2, 4), namely a receiving component (2) and a connector component (4). The connecter component (4) includes a connecting shaft (6) which is inserted into a locator opening (8) of the receiving component (2) and is sealed around the perimeter and arrested against loosening by a holding element (20) situated in a recess (22) of the receiving component (2), first in a partially inserted, incompletely sealed, pre-locked position and secondly in a fully inserted, perfectly pressure sealed full lock-in position. The holding element (20) has arresting elements (28, 30) each of which engage behind a locking edge (24) of the connector component (4) when a lock-in connection (28, 24; 30, 24) is formed. The holding element (20) is relatively movable axially in the recess (22) of the receiving component (2) in such a way that at least in a full lock-in position, at least one arresting element (30) can be transferred, by shifting of the holding element (20) against the direction of insertion, from an unlocked position in which the respective lock-in connection (28, 24; 30, 24) can be released, to a locked position in which release of the lock-in connection (28, 24; 30, 24) is prohibited.

Plug-in coupling for pressure application systems

A plug-in coupling for pressure application systems, including two coupling components such as a housing component and a connector component. The connector component is sealed insertable into a locating opening of the housing component, and is arrestable against loosening by a locking device. The locking device has an elastically deformable holding element, which is located on the side of one coupling component in such a way that, in the inserted state, it engages behind an arresting step of the other coupling component, locking with positive fit, for arresting said connector component. The holding element is designed ring-shaped and comprises several individual annular segments and one concentric spring lock washer component which presses the annular segments with radially operating spring resistance that each annular segment can move radially against or through the spring resistance of said spring lock washer component during the plugging-in.

Plug-in coupling for pressure fluid systems

A pipe fitting (1) for connecting a metallic pipe line (10), including a pipe union (4), which contains a receiving opening (8) for the pipe line (10), a swivel nut (6), which can be threadedly connected with the pipe union (4), as well as metallic cutting ring (18), which is disposed between the pipe union (4) and the swivel nut (6). The cutting ring (18) with an outer cone (30) acts jointly with an inner cone (28) of the pipe union (4) in such a manner, that, when the swivel nut (6) is tightened, it cuts into the material of the pipe line (10) with at least one cutting edge (32) and generates a form-fitting junction. The cutting ring (18) includes--where it joins an outer cone (30)--an essentially radial contact surface (38) for the purpose of limiting the tightening force, when it comes into contact with a face surface (40) of the pipe union (4). The cutting ring (18), in the transition region between the outer cone (30) and the contact surface (38), contains an elastomeric circumferential seal (44) in such a manner, that the circumferential seal (44), when it is in the assembled condition, is under an elastic pre-stress between the cutting ring (18) on the one hand, and at least one partial region of the interior cone (28) of the pipe union (4), which joins the face surface (40) on the other hand.
