A removal system is provided with a separating element for separating contaminants contained in a fluid and with a removal aid for removing the separating element from a housing. The separating element has an end disk arranged at an end face of the separating element. The end disk has a central recess. The removal aid has a grip section and at least two locking fingers. The locking fingers extend along a center axis of the removal aid away from the grip section. Each locking finger has a hook element that serves for engaging behind the end disk of the separating element radially outside of an end disk area that delimits in radial outward direction immediately the central recess. A removal aid for such a removal system is provided.

The invention relates to a filter element () for use as a particulate filter in a cooling circuit (), in particular of an electrochemical energy converter, having a conical grid support structure (). The filter element features at a first axial end a supply opening () for supplying a cooling medium to be filtered into the filter element () and the grid support structure () carries a filter medium (). The filter element () has axially opposite the supply opening () a funnel () for axially discharging and collecting particulate impurities, and is closed at second axial end. The conical grid support () structure tapers from the first axial end to the second axial end. An arrangement of a fuel cell () having a a cooling circuit () with the filter element is disclosed.

Removal system and removal aid for a separating element

A filter element is provided with a filter medium and a first end disk connected to the filter medium. A first bayonet protrusion is disposed on the first end disk and designed to engage behind a first bayonet receptacle of a filter housing of a filter. The first bayonet protrusion has a free end. The first bayonet protrusion projects at least over sections thereof in a radial direction relative to a filter element longitudinal axis of the filter element past the filter medium. The free end projects in the radial direction toward the filter element longitudinal axis. A filter with a filter housing provided with a first bayonet receptacle is provided and the filter element is arranged in the filter housing such that the first bayonet protrusion on the first end disk engages behind the first bayonet receptacle of the filter housing.

A filter element for a fuel filter has first and second end plates and a particle filter medium arranged between the first and second end plates. A bayonet protrusion on the first end plate is designed to engage a bayonet receptacle of the filter housing by rotation of the filter element about a filter element longitudinal axis. An internal sealing element on the second end plate is designed to separate a raw side from a water collecting chamber of the fuel filter. The filter housing has a filter housing body and a cover screwed onto the filter housing body. The filter housing has a bayonet receptacle arranged on its inner side. By rotating the filter element about a filter element longitudinal axis of the filter element, the bayonet protrusion engages the bayonet receptacle of the filter housing when the cover is unscrewed from the filter housing body.

A filter element () has a filter bellows () arranged about the longitudinal axis (L) and having a first end disk () on a first end face (), and a second end disk () on a second end face (). A central element () is arranged rotatably about the longitudinal axis (L) relative to the filter bellows () in the interior () of the filter bellows (). The central element () has one or multiple positioning elements () which interact with counter positioning elements () of an upper housing part () to fix the central element in the upper housing part () in a defined angular position. The central element () has at least one electrical connector element () on the element, electrically contacting at least one electrical connector element () on the housing.

A filtering system () includes a filter head () and a replaceable filter (). The filter head () has a feed line () and discharge line (). The replaceable filter () is removable and replaceably mounted onto the filter head () by a rotational and/or plug connection () and includes a housing () with at least one inlet () for oil to be filtered and at least one outlet (). The inlet () communicates with the feed line (). The outlet () communicates with the discharge line (). The housing () has a filtering element () that sealingly separates the inlet () from the outlet (). The filter head () includes an auxiliary oil line (). The replaceable filter () has a flow control element () that automatically closes or releases the auxiliary oil line () dependent on an operation and/or assembly condition.

A sealing arrangement for a coupling for refrigerant lines comprises a first coupling piece, which is connected sealingly to a first line end piece, and a second coupling piece which is connected sealingly to a second line end piece. In the sealing arrangement, a sealing ring is held on the sealing face of one of the two coupling pieces by a holding device which is configured as a plastic cap having a through hole. The plastic cap has at least one predetermined breaking location () which is configured as a groove which reduces the material thickness of the plastic cap in such a way that the material integrity at the predetermined breaking location () is maintained during assembly and breaks apart during disassembly.

A corrugated hose pipe assembly has a corrugated pipe that is surrounded by an elastomeric high-pressure hose. The ends of the high-pressure hose are grasped and fixed by connectors. The connectors each have a pipe piece () which is fitted with a circumferential, radially projecting stationary nipple stop () at the axial end thereof facing the corrugated pipe. A hose nipple (), which is positively mounted on each pipe piece (), is provided with a radially protruding, circumferential hose stop () at the end of the hose nipple ().

A connecting assembly for coolant lines, in particular for motor vehicle air conditioning systems which are operated with CO, from a first coupling element that can be connected to a first line end piece, and a further air conditioning circuit component. The first coupling element and the air conditioning circuit component are joined by a screw so that the first line end piece and the air conditioning circuit component are connected to one another by means of one bore each and radially extending sealing faces. A sealing ring is arranged between the faces. A space holder is arranged between the first coupling element and the further air conditioning circuit component. The first line end piece has a radially extending sealing face which is produced by plastic deformation of the line end piece without removing material. The first coupling element has an annular collar which presses the sealing face onto the sealing ring in the mounted state.

Connecting arrangement for refrigerant lines

A connecting arrangement for coolant lines includes a first coupling piece, connected seal-tight to a first line endpiece, and a second coupling piece, connected seal-tight to a second line endpiece. The coupling pieces each have radially extending sealing surfaces on the side facing toward the other coupling piece. A sealing ring is mounted between the sealing surfaces. The coupling pieces are joined to each other via a screw arranged laterally offset from the sealing surfaces so the line endpieces connect to each other via respective bores in the coupling pieces. A form body between the coupling pieces arranged at a spacing from the screw on the side facing away from the sealing surfaces is configured so a lever action occurs when the coupling pieces are joined to each other leading to a uniform pressing together of the sealing ring between the sealing surfaces of the coupling pieces.
