The overlapped inner end of the clamping band (10) is formed as a tongue (11) with a reduced width compared to the clamping band (10) and is received by a tongue channel (45) arranged in the outer band section. The tongue (11) is stamped out of the clamping band (10) and has outwardly projecting side flaps (42) and a bottom part (43) which is arranged between them, formed from the clamping band (10) and rises continuously from the clamping band (10) up to the height of the side flaps (42).

Abstract: The flow path switching valve described herein has a valve chamber with three openings and a valve piston disposed in the valve chamber. The valve piston has a flexible diaphragm which at its circumference co-operates sealingly with an inner circumferential wall of the valve chamber. The valve piston is movable between two end positions; in a first end position, it opens a flow path between a first opening and a second opening and blocks a third opening, and in the second end position, it blocks the first opening and opens a flow path between the second opening and the third opening. The wall of the valve chamber is shaped such that in the last phase of the diaphragm movement to the first end position, the sealing contact between the diaphragm and the inner wall is undone in at least part of the circumference.

Abstract: A shrink-fit ring, the two circumferential edges (10) of which are flanged, makes it possible to use thinner band thicknesses without the risk of buckling owing to its greater intrinsic strength. The circumferential edges (10) end in limbs (16) which point radially outwards and enclose an angle of approx. 70° to 90° with an unflanged centre portion (13) of the ring that is located axially further inwards. The flanging results in an extension of the diameter of the ring edges, wherein the ring edge regions (14) are bent outwards in a rounded manner and the edge surfaces (11) run at an angle of preferably approx. 0° to approx. 20° with respect to the ring axis (12).

Abstract: A tension clamp (19) includes a band (20) surrounding an object to be fastened and a buckle (21) arranged on the inner band end portion (22) and surrounding the band (20), with the outer band end portion (23) extending through the buckle (21). A tool for mounting the tension clamp includes a holding device for holding the buckle (21) along with the band (20) surrounding the object to be fastened, a tensioning device for tensioning the band (20) round the object to be fastened by applying tension to the outer band end portion (23), a locking device (50) for locking the buckle (21) on the band (20), and a severing device for cutting off excessive band length. The locking device (50) has plier jaws (54) adapted to be inserted into lateral windows (25) of the buckle (21) for deforming side edge portions (24) of the other band end portion (23).

Abstract: A tool for fixing a tension clamp including a pair of levers pivotable about parallel axes and carrying at their ends plier jaws that can be moved toward each other and act on the clamp. To monitor the forces occurring during the locking of a buckle and a clamping band of the tension clamp, use is made of a device that has a housing fixed with respect to the tool and power transmission arms. Each power transmission arm is at one end elastically articulated to the housing, has at the other end a contact surface for a force sensor (18) attached to the housing and has, between its ends, a bore, in which the axis of the relevant tool lever is supported. A force/time or force/path curve obtained from the sensor signals is used as a measure of the quality of the locking between the buckle and the clamping band.

Abstract: For producing a welded ring, a band having a length corresponding to the circumference of the ring is bent to form a ring and its two ends are welded together. The band ends to be welded together have an offset in the circumferential direction of the ring, the offset lying in the plane of the band. The welding is performed form both lateral edges of the ring from the outside up to the offset. This avoids an overlapping weld of a welding quality that is different at the centre of the ring from that at the edges.

Abstract: A low-profile clamp consists of a band (20) and a buckle (21) mounted on a first end portion of the band. During mounting, the second and portion (23) of the band (20) which surrounds the object to be fastened is fed through the buckle (21); after tightening the band is locked to the buckle (21) by deformation. The deformation may be done with a plier-type tool which engages the side edges (37) of the second band end portion (23) through lateral windows (36) formed in the buckle (21).

Abstract: A compression ring made of an initially open clamping band has ends which mutually engage in puzzle-like fashion for closing the compression ring. One band end carries a tongue which projects in the longitudinal direction of the band and has arms extending transversely to the longitudinal direction of the band, and the other end of the band is formed complementarily thereto. The transverse edges of the arms, which extend transversely to the longitudinal direction of the band and face the free end of the tongue, each have a convex part at the outer end and a concave part at the inner end.

Abstract: A diameter variable hose clamp includes a clamping band having end portions which mutually overlap in the closed condition of the hose clamp. The inner end portion carries a tongue which has a width smaller than the full width of the clamping band, and hooks for closing of the hose clamp. The outer end portion is provided with openings for receiving the hooks, an ear-like tightening device for tightening the hose clamp around an object to be clamped, and an arcuate band portion for receiving the tongue. The arcuate band portion is cut free from the clamping band by longitudinal cuts in forming lateral band webs.

Abstract: An open hose clamp having a clamping device, i.e., a so-called Oetiker ear. The clamped state is locked by serrated sections which engage with each other outside of the ear section on the side of the ear facing away from the outer clamp strip end. In the locked clamped state, the load on the ear is reduced so the hose clamp does not lose its clamping function even if the outward-protruding ear is damaged. The width of the clamping strip in the area of the ear is reduced compared to the remaining full clamping strip width.

Abstract: An open ear clamp having a clamping device like a so-called Oetiker ear. To make the installation of the clamp on a pipe easier, the clamp is pre-deformed, for example, in the course of production, to such an extent that the clamp surrounds the pipe for which the clamp is intended without play. Because of the elasticity produced in the clamp by this pre-deformation, the clamp still can be moved effortlessly to the installation location on the pipe and yet is retained there in the position of the clamp and in the desired orientation.

Abstract: A tension clamp (19) includes a band (20) surrounding an object to be fastened and a buckle (21) arranged on the inner band end portion (22) and surrounding the band (20), with the outer band end portion (23) extending through the buckle (21). A tool for mounting the tension clamp includes a holding device for holding the buckle (21) along with the band (20) surrounding the object to be fastened, a tensioning device for tensioning the band (20) round the object to be fastened by applying tension to the outer band end portion (23), a locking device (50) for locking the buckle (21) on dem band (20), and a severing device for cutting off excessive band length. The locking device (50) has plier jaws (54) adapted to be inserted into lateral windows (25) of the buckle (21) for deforming side edge portions (24) of the other band end portion (23).

Abstract: In a rapid coupling, a pipe nipple engages a through hole of a socket. A first annular groove provided on the pipe nipple serves to catch a locking ring provided in the socket, in order to lock the coupled condition. A sleeve is movable on the pipe nipple, the sleeve having an inner projection to be retained by the first annular groove of the pipe nipple in a pre-assembled condition. When the pipe nipple is inserted into the socket, the sleeve abuts the socket and is then moved along the pipe nipple until the inner projection is caught by a second annular groove if the coupling is properly locked. It the pipe nipple is not moved into the socket to such an extent that the locking ring is caught by the first annular groove, the second annular groove remains visible outside the sleeve to indicate the improper coupling condition.
