Abstract: A screw connection device for connecting the flared ends of two pipes includes a nut, a screw and distance element which comprises a first recess or shape for accommodation of the flare at the end of a first pipe, and a second recess or shape for accommodation of the flare at the end of the other pipe. The nut and screw each accommodate one pipe end with the distance element between them with the recess at each end in sealing contact with the pipe flares. The nut and/or the pipe flare of the pipe end which in the connected state is accommodated in the nut comprise positive-fit elements, which positive-fit elements are designed such that the accommodated pipe end is secured against rotation relative to the nut.

Abstract: A multi-layer tubing composed of a first layer, a second layer and an intermediate layer interposed between the first layer and the second layer. The first layer contains a first melt-processible thermoplastic such as polyamides, thermoplastic elstomers, and mixtures such materials. The second layer contains a second melt-processible thermoplastic chemically dissimilar form the melt-processible thermoplastic employed in the first layer. The intermediate layer is made of a solidified melt-processible thermoplastic solution which contains the first melt-processible thermoplastic and the second thermoplastic such that the first thermoplastic and the second thermoplastic exist as discretely discernable components dispersed relative to one another in an essentially non-homogenous manner.

Abstract: In a method for grounding a metal tube (2) sheathed with an electrically non-conducting plastic layer (1), has the plastic layer (1) of the metal tube (2) completely removed at an area of connection (3) the area of connection (3) is connected to the motor vehicle part in an electrically conducting fashion by a conductive covering section (4) is closed in the circumferential direction of the metal tube (2) which covers the area of connection (3) on all sides or more than covers the area of connection (3) on all sides, i.e. in the form of a crimp sleeve or a heat-shrinkable sleeve. It is first pushed onto the metal tube (2) and is then pressed onto the metal tube (2) at least at its ends under radial pressure applied along at least part of the circumference without any gaps. In one form, the tube has a bead in the area where the plastic layer is removed and the bead is in contact with the conductive covering section.

Abstract: A rapid-action coupling for hoses or rigid lines with a coupling box, a plug-in nipple and a locking element. The coupling housing has a recess and an opening that extends essentially vertically with respect to the longitudinal axis of the recess. The plug-in nipple and the coupling housing are connected by introducing the nipple into the recess. The nipple is locked by introducing a locking element into a first end of an opening into engagement with the housing. The locking element includes an arm for releasing the engagement.

Abstract: The invention proposes a method for clamping a pipe with a hose or a pipe with the aid of a compression sleeve, in which the influence of dimensional tolerances of the components on the quality of the compressed connection is significantly reduced. In the method according to the invention, the pressing force between a compression tool and the compression sleeve as well as the advancing distance of the compression tool are determined and evaluated.

Abstract: The invention proposes a connection between tubing and a hose which can be easily and inexpensively produced, requires little installation space and results in favorable hydraulic properties. The connection is realized by means of a connecting piece that is integrally formed onto the tubing.

Abstract: Processes and arrangements provide a rigid line for a brake, fuel or hydraulic system in motor vehicles, whose synthetic cladding layer is reinforced with fibers to thereby increase the strength and the resistance to wear and tear of the synthetic cladding layer. Moreover, by the use of electrically conductive carbon fibers, electrostatic charging of the rigid line can also be prevented.

Abstract: A quick coupling for hoses or pipelines with a coupling sleeve (1), a plug-in nipple (3) and a sealing element (21) is proposed, in which the sealing element (21) is tensioned in the locked state and/or has a rectangular cross section so that the tightness and the diffusion resistance of the quick coupling according to the invention are improved.

Abstract: A tube nut and a threaded connection between a brake hose and a brake line, as well as a tool for tightening and loosening the tube nut according to the invention are proposed.

Abstract: The invention relates to a hose fitting, more specifically, for a brake arrangement in a motor vehicle, for connecting, in a compression-proof manner, a multi-layer hose to a metallic end piece. At least part of one free end of the end piece engages with the inside of the hose and features at least one bulge, with a metallic pressed sleeve encompassing the hose, overlapping the bulge and also featuring, lateral to the bulge, respective first pressed sections. The crux of the invention is based on the fact that elastic and electrically nonconducting surface layers are arranged on the hose and end piece, upon which are arranged, in each case, a second pressed section in a liquid-tight manner. The invention is associated with the advantage that a hose fitting is sealed with respect to electrolyte penetration from the outside, and that, moreover, local cell formation, with resultant corrosion of the hose fitting, is prevented.

Abstract: An electromagnetically actuated valve having an adjustable abutment is disclosed. The valve comprises a valve housing and at least one annularly-shaped solenoid coil, which is arranged in the valve housing and which, on its interior peripheral side, surrounds a magnet armature. The armature is capable of axially reciprocal motion with respect to the solenoid coil. The magnet armature is elastically braced in the area of its front end by a spring element that in turn transmits force against an abutment that forms a component of the valve housing. At its other end, the armature is provided with a sealing member that can be forcibly engaged against a valve seat, as needed. The abutment is adjustable relative to the valve housing along the axis of reciprocal axial motion of the magnet armature to enable adjustments to the prestressing of the spring element.
