The invention relates to a plug-in coupling for fluid systems having two coupling parts connectable to one another, which each have coordinated catches for connecting them together, one of the coupling parts having an end union section, by means of which it can be plugged into the other coupling part, and one of the coupling parts having at least one end retaining section carrying its catches, by means of which section it grips over an outer peripheral contour of the other coupling part, on which the coordinated complementary catches are formed. In order to achieve a simplified means of detachment whilst ensuring ease of assembly and a highly stable connection of such a plug-in coupling, it is proposed to provide a separate release part, which in the assembled state is held on the first coupling part and/or the second coupling part and which serves for separating the locking connection between the catches of the first coupling part and the catches of the second coupling part.

Plug-in coupling for fluid systems

The plug type connection of this invention consists of two coupling parts which can be fitted together, to be precise a socket part and a plug part, it being possible for the plug part, with a plug shank, to be inserted in a sealing manner into a locating opening of the socket part and to be releasably locked in the plugged-in state via a locking arrangement, the locking arrangement consisting, on the one hand, of two outer, radial, flange-like retaining webs, axially adjacent in the plug-in direction in the plugged-in state, of the two coupling parts and, on the other hand, of a retaining element which, with at least one retaining section which is C-shaped in axial section, axially and radially encloses the retaining webs of the two coupling parts in a positive-locking manner.

Connection for fluid lines

A connection system for conduits, fittings or assemblies which are intended for carrying a fluid acted upon by a pressure (p), in particular for systems carrying carbon dioxide. The connection system comprises a first coupling part such as a housing part, a second coupling part such as a plug part, and is capable of being introduced into the first coupling part along an axis. At least one gas-permeable circumferential seal is arranged in a groove in one of the two coupling parts. One coupling part is capable of being plugged with a shank into a round receiving orifice of the other coupling part. After plugging-in, the circumferential seal seals off a gap between the outer radius of the shank and the inner radius of the receiving orifice.

Connection system

A receiving part of a fluid plug-in coupling is provided. The receiving part comprises a socket housing having a plug-in opening for a plug part and a sealing arrangement, which is arranged in the socket housing, for the plugged-in plug part. In this case, the sealing arrangement is fixed axially in the removal direction of the plug part by a closing bushing, and the closing bushing is secured directly in the socket housing via a locking portion.

Receiving part of a fluid plug-in coupling

A socketless fitting for releasable connection of a pressurized line. The fitting has a housing body with a receiving opening to insert one end of the line, and an inner sleeve attached in the housing body in an arrangement that extends coaxially within the receiving opening for engagement into the inserted line end. The inner sleeve is fastened in the housing body media-tight around the periphery by a connector and preferably engages in the line media-tight around the periphery. A clamping element axially movable in the receiving opening cooperates with an inner surface of the housing body to secure the line end onto the inner sleeve. Media-tight outward sealing is accomplished by sealing engagement of the essentially rigidly secured inner sleeve in the line, because the inner sleeve itself is also tightly joined to the housing body.

Plug connector for quick-release connection of pressurized lines

A socketless fitting for releasable connection of a pressurized line. The fitting has a housing body with a receiving opening to insert one end of the line, and an inner sleeve attached in the housing body in an arrangement that extends coaxially within the receiving opening for engagement into the inserted line end. The inner sleeve is fastened in the housing body media-tight around the periphery via connectors and preferably engages in the line media-tight around the periphery. Media-tight outward sealing is accomplished by sealing engagement of the essentially rigidly secured inner sleeve in the line, because the inner sleeve itself is also tightly joined to the housing body.

Plug connector for rapid and releaseable connection of pressurized lines

The invention pertains to a plug connection for pressure systems which consists of two coupling parts, namely a receptacle part (2) and a plug part (4). The plug part (4) can be inserted into a receptacle opening (8) of the receptacle part (2) with a plug shaft (6) such that it is circumferentially sealed and blocked from being separated by a locking device (12). The locking device (12) is realized in such a way that a partially plugged prelocking position (FIG. 1b) and an entirely plugged full locking position (FIG. 1a) are ensured. In the prelocking position, an incomplete seal is produced such that a signal, preferably an acoustically perceivable leakage noise, is generated if the plug connection is charged with pressure. A complete, pressure-tight seal is produced in the full locking position. The locking device (12) comprises a holding element (20) that is situated in a recess (22) of one coupling part (2) and realized in such a way that it respectively engages behind the same locking edge (24) of the other locking part (4) in the prelocking position (FIG. 1b) as well as in the full locking position (FIG. 1a).

Plug connection for pressure systems

The present invention relates to a pressure medium plug-in connector, consisting of two connector parts, i.e. a housing part (2) and a plug part (4), wherein the plug part (4) with a plug shaft (6), via at least one peripheral seal (10) located in an annular groove (14) of the one connector part (4) and interacting with a peripheral sealing surface (18) of the other connector part (2), can be inserted in a sealed manner into a receiving opening (8) of the housing part (2) and can be secured against release by means of a locking arrangement (12). The locking arrangement (12) is constructed in such a way that a partially plugged, prelocked position and a completely plugged, fully locked position are ensured. In the prelocked position, a seal is present which is so incomplete that, if pressure is applied with a pressure medium, a clearly limited perceptible leak, particularly in the form of an audible leaking sound, occurs. In the fully locked position, via the peripheral seal (10) resting against the sealing surface (18), a complete, pressure-tight seal is present. The area of the peripheral seal (10) and/or of the sealing surface (18) is constructed in such a way that the peripheral seal (10), located in the annular groove (14) of the one connector part (4)--in the prelocked position [and] via peripherally distributed contact points (20) arranged a distance apart--rests in radial direction against the other connector part (2), wherein respectively in peripheral direction, between the contact points (20), axial leakage paths (22) are formed. Hereby, the peripheral seal (10) is protected against a tearing out brought about by the flow.

Plug-in connector for pressure medium systems

A plug connection for a pressure system comprising a receptacle part and a plug part, the plug part is inserted into the receptacle part and retained therein by a locking device which forms a prelocked, unsealed connection and a locked, sealed connection between the plug part and the receptacle part with a limit stop element which indicates when the locked, sealed connection has been obtained.
