  • Patent number: 9334991
    Abstract: A device for the connection of free pipe or hose ends provided with flanges, with first, second, third, and fourth clip segments connected to one another in jointed manner, with an essentially U-shaped cross-section, a tensioning lever arranged at one free end of the first clip segment, and at least one spring, wherein the clip segments engage from the outside over the flanges of the pipe or hose ends pushed together, and wherein the free ends of the first and fourth clip segments can be locked by means of the tensioning lever and spring(s). In order to exclude spontaneous opening of the closed device under any circumstances, provision is made for the tensioning lever to be capable of engaging in the tensioned position in positive fit with the free end of the adjacent fourth clip segment with the tensioning lever capable of being connected.

  • Patent number: 8616588
    Abstract: A pipe coupling for connecting two pipe ends having two coupling parts which are partially mated. At least one annular groove having an inserted seal is in the contact region on the outer side of the male part and/or the inner side of the female part. The male part includes an outer ring land and the female part includes a shoulder enclosed by a coupling clip in a form-fit manner when the pipe coupling is closed. In order to design and refine the pipe coupling so that it is possible to provide a pipe having a coupling clip in combination for simplifying the operational procedure, an annular groove is provided on the outer side of the female part into which a guide tab disposed on the inner side of the coupling clip is inserted when the pipe coupling is closed.

  • Publication number: 20120217739
    Abstract: Illustrated and described is an apparatus for connecting double jacketed pipes, comprising two fixed flanges and a locking element for connecting the fixed flanges axially; the fixed flanges respectively comprising an inner ring and an outer ring connected in a torque-proof manner to the inner ring; an inner pipe being assigned to each of the inner rings and a jacket pipe being assigned to each of the outer rings, and the fixed flanges respectively having between the inner ring and the outer ring at least one axial bore hole spaced apart from one another by an annular space. In order to achieve easy fitting of the coupling with double pipes, the pipes of which can not be displaced axially relative to one another, it is proposed to arrange an axially displaceable telescopic pipe at least between one of the outer rings and the jacket pipe assigned to it.

  • Patent number: 7434851
    Abstract: A device is illustrated and described for connecting two ends of high-pressure pipelines for use in longwalls of underground mining, having a removable pipe coupling for tension-proof and tight connection of the two pipe ends whose constructions are tailored to one another. In order to counteract the catching as the pipeline is displaced in the longitudinal direction, so that damage or even destruction of the pipeline or pipe connections may be reliably prevented, each pipe end is reinforced using an essentially conical ring, whose outer surface expands from the external diameter of the pipe up to the external diameter of the pipe coupling.

  • Patent number: 7195288
    Abstract: The invention relates to a pipe coupling comprising a socket component and an insert component which is partially insertable to securely fit into the socket component. A ring groove between the socket component and the insert component is sealed by a ring seal. The socket component is releasably connected to the insert component by means of a union nut which contacts a shoulder of the insert component rearwardly for joined movement into the closed position. The union nut is screwed onto the socket component along a cylindrical and/or conical exterior thread. The ring gap between the union nut and the insert component is sealed. The ring gap between the union nut and the socket component is also sealed. The thread connection between the socket component and the union nut is positioned between the two sealing positions.

  • Patent number: 7182095
    Abstract: A valve, particularly a vapor valve, is disclosed and includes a housing into which an intake connecting piece, an outlet connecting piece, and a pressure relief outlet discharge, having a spherical closing part, mounted so it is rotationally movable by a lever. The outlet connecting piece is connected to the pressure relief outlet in the closed position (closed setting). An air supply inlet discharges into the housing and the spherical closing part may be rotated by more than 90° and is implemented so that after the closing motion around 90°, the closing part may be rotated further in the closing direction with the valve closed until the outlet connecting piece is connected to the air supply inlet with the pressure relief outlet closed again (purge setting).

  • Patent number: 6672631
    Abstract: A pipe coupling comprising two clamp halves connected on one end and with a rapid action closure for separably connecting the diametrically opposing other end. The rapid action closure contains a screw bolt, one end of which is coupled to one of the clamp halves and onto the other end of which a screw nut tightens the clamp half into the closed position. A lever lockable in the closed position by a bow-type spring is coupled to the screw nut. The pipe coupling comprises a bow-type spring in each clamp half, wherein the eyelet of the bow-type spring is centrally coupled to the region of the articulated connection between the clamp halves and the free end of the bow-type spring is held in the region of the end of each clamp half which is situated on the rapid action closure such that it can be longitudinally displaced.

  • Patent number: 6523230
    Abstract: The invention relates to a hose coupling comprising a clip consisting of at least two semi-cylindrical cups (1a, 1b) enclosing the hose and a clamping lever (3) which via a bolt (4) is articulated on the free peripheral end of one of the semi-cylindrical cups (1a, 1b). To create a force-fit connection between the hose and a sleeve (8) inserted into same, the clamping lever can be connected to the other free peripheral end of the corresponding semi-cylindrical cup (1a or 1b) via a closing spring (6). The clamping jaw (1) can be fixed on the sleeve (8) in an axial direction by means of a flange which is mounted on said sleeve (8) in such a way that it cannot be axially displaced. The aim of the invention is to provide such a hose coupling which has a simple structure, is economical to produce and can be used as quick-release coupling for corrugated flexible hose.
