Abstract: The present invention relates to a line connector for media lines, consisting of a connector piece with at least one junction portion for junction connection to a media line or to an assembly and with a transitional portion contiguous to the junction portion and having a flow duct. In this case, at least in the region of the transitional portion, electrical heating means are provided in an arrangement at least partially surrounding the flow duct. Furthermore, the invention relates to a ready-made media line consisting of a pipeline with a heating conductor arranged on the circumference and with a heatable line connector fastened at least to one pipeline end of the media line.

Abstract: The present invention relates to an electrically heatable media line (1), comprising a fluid line (2) and at least one fluid connector (4) connected to a line end (2a). The fluid line (2) and the fluid connector (4) respectively have electric heating means (6, 10), wherein the fluid line (2) and/or the fluid connector (4) including electric connections (16) of the heating means (6, 10) are/is enclosed by a plastic molding compound.

Abstract: The present invention relates to a fluid line for conducting and heating a medium, having a heating line comprising a conduit and an electrical heating element which is assigned to the conduit. In this case, a particular heating power per unit length can be set, the heating element comprising at least three heating conductors which run along the conduit. The ends of the heating conductors are connected to one another and can be connected to a supply voltage in such a manner that a plurality of heating conductors are connected in series and/or in parallel such that, for a particular supply voltage, the heating power of the fluid line is determined by the total resistance of the heating conductors.

Abstract: In at least one embodiment of the present invention a connector unit for a pressure medium connection between an outer connection part and a spring head of a vehicle gas spring is provided. The connector unit comprises a line configured to be connected to an inner connection part and the outer connection part and is elastically deformable in at least regions during relative rotation movement of the spring head. The line has a deformation section between an end-side line section and an outer line section. The deformable section is disposed in a region of the spring head which is offset to the spring axis and is of helical configuration.

Abstract: A connection system for conduits, fittings or assemblies which are intended for carrying a fluid acted upon by a pressure (p1), 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.

Abstract: The invention relates to a damper arrangement, in particular an air spring strut, comprising a shock absorber having an essentially cylindrical housing and an air spring with a working space which is under internal pressure, and comprising an additional volume which can be connected to the working space via a closable flow duct. It is proposed to enclose the additional volume by a hollow body which surrounds the shock absorber which can be fastened thereto and is formed from an outer cylinder and an inner cylinder, which is connected to the latter and, in particular, is arranged concentrically.

Abstract: A receiving part of a fluid plug-in coupling is provided, including a socket housing having a plug-in opening for a plug part and having a retaining device for releasably fixing the plugged-in plug part in place. The retaining device has a retaining element mounted in the socket housing and radially elastically deformable retaining sections for latching engagement behind a radial retaining step of the plug part. A release element is secured in an axially displaceable manner relative to the socket housing via latching means. The release element engages by means of an inner release section the plug-in opening and acts against the retaining sections of the retaining element. A securing element is provided such that the release element is blocked in a secured position agains a release movement and is unblocked in an unblocked position for a release movement.

Abstract: The present invention relates to a silencer for the damping of noises occurring in pneumatic pressure systems as a result of pressure blow-off flows from a pressure side to an atmosphere side. The silencer consists of a housing surrounding an expansion space, with a pressure-side inlet for the blow-off flow and with an opposite atmosphere-side outlet. A damping element consisting of a porous material through which a flow is capable of passing is arranged within the expansion space in the vicinity of the inlet. The damping element has a flow area through which a flow is capable of passing, which is larger than the inner cross-sectional area (A1) of the expansion space.

Abstract: A novel type of customizing kit for a vehicle air suspension system, comprising an additional air spring volume with a connecting line which can be connected to a vehicle main air spring volume, and with a switching device for selective connection or disconnection of the additional air spring volume. The switching device is arranged in the area of the connecting line and is designed such that when it is in an open position, it releases the cross section of the connecting line virtually completely for flow to pass through in both directions and when it is in a closed position, reduces the cross section to a specific residual opening cross section, such that this results in effective closure of the connecting line by use of a Helmholtz effect in a specific region of an excitation frequency of the oscillating air volume.

Abstract: The invention relates to a receiving part (2) of a fluid plug-in coupling, comprising a socket housing (10) having a plug-in opening (12) for a plug part (4) and having a retaining device (14) for releasably fixing the plugged-in plug part (4) in place. The retaining device (14) has a retaining element (16) which is mounted in the socket housing (10) and has radially elastically deformable retaining sections (18) for latching engagement behind a radial retaining step (6) of the plug part (4), and a release element (20) which is secured in an axially displaceable manner relative to the socket housing (10) via latching means (22). The release element (20) engages by means of an inner release section (24) in the plug-in opening (12) and, for release purposes, acts against the retaining sections (18) of the retaining element (16).

Abstract: The present invention provides for a pipe fitting for a panel, especially for a panel of a lid for a container, as on a container wall. A pipe section protruding from the panel is provided wherein the front of the pipe fitting is fastened to the panel in the assembled state. A flange having a groove for a seal and a pipe socket extend from the pipe section for passing through an opening in the panel. The pipe socket forms a positive fit connection to the panel through deformation to the assembled state and the seal provides a non-positive fit against a surface of the panel.
