A valve arrangement has a valve unit () fixed in position via two mutually spaced attachment structures (and) on a mounting face () of a valve support (). The first attachment structure () includes two mutually engaged hook sections (and). The second attachment structure () includes a U-like retaining clip (), which is so able to be attached to the structural unit comprising the valve unit () and the valve support () that its clamping limbs (and) act on clip sections (and) and accordingly braces the valve unit () onto the valve support ().

A connection device for fluid lines has an annular or sleeve-shaped insert provided for assembly by plugging in a circularly cylindrical socket in a support component. The insert comprises an annular or sleeve-shaped cage element () in the form of a metal bent stamping with an annular support section () having several claw elements () and several support legs () extending from the support section in the same axial direction. The claw elements () serve for securing an inserted fluid line and the support legs () serve for supporting a preceding seal.

A coupling device for a fluid line has a collet and an axially movable actuating sleeve serving for operation of the collet. The collet bears several gripping teeth with associated actuating portions able to be acted on by actuating faces on the actuating sleeve in order to hold the inserted fluid line. In the non-operated state of the actuating sleeve there are at least partly different distances between the mutually associated actuating portions and actuating faces so that on actuation of the actuating sleeve several actuating portions of the collet are acted on one after the other. This means that the necessary actuating force is reduced.

A pinch valve has a hose-like valve member with a flexible peripheral wall adjacent to whose outer periphery two diametrally opposite pinch elements are arranged able to be moved toward and away from one another with a greater or lesser pinching of the peripheral wall while performing an operating movement athwart the valve member longitudinal axis. An annular actuating ring coaxially surrounding the valve member may act on the pinch elements for causing the operating movement. The actuating ring is placed in a working space surrounded radially from the outside by a peripheral valve housing wall and is able to be acted on by drive means separate from the actuating ring with a drive force controlling the actuating movement.

A hinged armature valve having a drive part and a control part affixed thereto, the drive part comprising an electromagnet unit, which is embedded in a drive part housing, fashioned of plastic material, molded in place during manufacture. The control part defines a control chamber in which a hinged armature is accommodated able to be pivoted for selectively opening and closing of two valve openings. The control part housing as well consists of plastic material, it being connected with the drive part housing in the joint region by a surrounding laser weldment in a gas-tight manner.

A choke valve, whose choke body comprises a cylindrical choke position plunging coaxially into an inlet duct. The inlet flow duct is connected on the one hand with an inlet and on the other hand communicates through transfer openings with outlet flow ducts extending through the wall of the flow duct, such outlet flow ducts begin connected with the outlet. Between the choke piston and the inlet flow duct wall a seal area is provided, which on resetting the choke body is shifted axially and, cooperating with the transfer apertures, sets the aperture for the pressure medium.

A sealing ring having a base body manufactured of thermoplastic synthetic resin material and a sealing body of elastomeric synthetic resin material. The two bodies are molded permanently on one another and each possess a sealing section, which serves for producing a sealing action at sealing faces of two oppositely placed components which are to be sealed in relation to each other.

Sealing ring

A control valve includes a generally hollow, cylindrically-shaped main body which at one end is integrally connected to a nozzle which has a bore therethrough and a flat external annular sealing surface which is contactable by a separate sealing element. Inside of the main body is positioned a valve part which at one end includes separate inlet and outlet hose connections for separate connection to, respectively, a pressurized control medium and to a controlled operating unit which controls the operation of the movement of the sealing element, and at the other end has a hollow cylindrical interior in which is positioned an axially-loaded spring, a valve piston and a sealing ring, the spring loading the valve piston against the sealing ring. A rod or tappet which at one end contacts the separate sealing element extends through the bore in the nozzle and through an axial bore in the sealing ring and abuts against the valve piston. A bore provides for fluid communication between the hose connection connected to the pressurized control medium and the hollow cylindrical interior of valve body and, when the separate sealing element is in contact with the flat external annular sealing surface of the nozzle, the inlet hose connection and the outlet hose connection are in fluid communication.
