Abstract: The invention relates to a compensation element for joining components made of fusible plastics, designed as a hollow cylinder, at least some sections of which are conical and having at least one heating element which when supplied with energy heats at least some regions of the inner surface or the outer surface of the compensation element or of both surfaces to produce a welded connection between the components. Said compensation element is characterized in that cuts are provided, starting from each outer edge of the hollow body, at least one section of the cuts extending up to or beyond a plane of the compensation element that guarantees flexibility. The invention also relates to methods in which a sleeve consisting of an outer sheath and at least one compensation element is used.

Abstract: The invention relates to a shut-off device comprising a housing which is to be connected to an adjacent conduit in a pressure-tight manner. A tubular passage is defined in the housing for a medium flowing through the conduit. Said device also comprises at least one sealing body which can be displaced by an articulated mechanism, by means of an adjusting drive that can be moved vertically in relation to the direction of flow, from an open position into a closed position in which the sealing contour of the at least one sealing body comes into contact with the tubular passage in a radially sealing manner. The articulated mechanism is guided parallel to the direction of displacement of the adjusting drive and comprises a bearing body to which the at least one sealing body is pivotably applied.

Abstract: The invention relates to a shut-off fitting comprising a housing which is connected to an adjacent pipeline in a pressure tight manner, the diameter of said pipeline defining a tubular passage in the housing. Said fitting also comprises at least one closing body which can be displaced between an open position and a closed position. The inventive shut-off fitting is characterized in that the at least one closing body can be displaced by an articulated mechanism, by means of an actuator which can be vertically displaced in relation to the flow direction, in such a way that it is arranged outside the tubular passage in its open position. The closing body has a contour which is adapted to the contour of the tubular passage, in the open position, and is located on the tubular passage in a radially sealing manner.

Abstract: A fitting for connection to a pipe includes a sleeve, in which a body is axially displaced along a sleeve axis, whereby the body has a drill for drilling into the pipe and/or a valve body of a valve. The fitting also includes a branch sleeve, located in particular on the sleeve and to which a branch line can be connected. The fitting is easily constructed in such a way that safety requirements are reliably met and such that a connection to a branch line can be easily established if necessary. According to another aspect of the fitting, a locking device which includes an actuating element is located in the branch sleeve, in such a way that the locking device is actuated by means of the axially displaceable body in the sleeve.

Abstract: A device for connecting components (1, 2, 3) made of fusible plastic, especially pipes (12, 60) of a fuel pipeline or a fuel line to a fuel tank (8) of a vehicle. The device includes a heating element (4) having ends (44, 46) which are used to supply electrical energy. The device is easy to use, simple to mount, and produces a functionally reliable welded joint between the components (1, 2, 3). To achieve this, one component (3) includes a retaining body (16) for a retaining tool (50), and the two ends (44, 46) of the heating element (4) extend onto the retaining body (16) where they can engage contact elements (56, 57) on the retaining tool (50).

Abstract: A tapping valve having a housing which can be electrically welded to a pipe and which includes a connection piece (2) with a drill (24) therein for drilling the pipe. The connection piece has an inner surface (34). The drill or a bushing (70) in which the drill can be moved axially by a threaded connection (74, 76; 80, 82) is provided with an external thread which engages the inner surface of the connection piece. Inner surface (34) is constructed such that it is initially cylindrical adjacent the external thread (32) and an inner thread can be formed in the inner surface (34) using the external thread (32) by rotating the drill (24) or the thread (70) in an axially forward direction (30). The tapping valve is easy to manufacture and yet offers a high degree of functional reliability.
