Abstract: A fuel distributor pipe (1) which can be subjected to a high internal pressure loading includes at least one connecting arrangement (12) serving for releasably connecting a branch pipe (3) and having a connecting bore (5) which extends radially through the wall of the distributor pipe and which has an inner portion (8) and an adjoining, outer portion (9) which enlarges in a hollow-conical configuration, a screwthreaded socket (12) which is connected to the distributor pipe and whose internal bore (15) extending therethrough continues the connecting bore and serves to receive the branch pipe, and a pressing element (22) having a pressure surface (23) which, when the pressing element is screwed on to a counter-pressure surface (24) provided on a thickened portion (25) of the branch pipe, exerts a force by which a counter-sealing surface (16) of the branch pipe is pressed against the conical wall (18) of the outer portion of the connecting bore.

Abstract: A fuel injection line for an internal combustion engine is provided at least one of its ends with a compression nipple formed thereon by upsetting, with a sealing taper portion having a sealing surface at a taper angle relative to the axis of the nipple. The taper portion, with plastic deformation of its sealing surface, serves for sealing against a hollow taper surface, with a corresponding taper angle, of a co-operating portion which is harder than the sealing surface of the nipple. Its rearward bearing surface which is intended for bearing against a hollow taper surface of a cap nut for fixing the nipple is in the form of a spherical segment which blends into the outside peripheral surface of the adjoining pipeline by way of a rounded portion.

Abstract: An injection line connection for internal combustion engines having for each pressure connection a connecting fitting which hitherto was upset out of the material of the injection line but which is still defective and which can be pressed by a cap nut, by way of a pressure ring, against an internal taper portion of a connecting member which carries the cap nut, is also suitable for thinner injection lines, free of disadvantages, by virtue of the following features, some of which are known and which are reproduced here by way of abstract:(a) the injection line (1) is a wall thickness in the range of from 1/5 to 1/3 of its outside diameter (D);(b) each pressure ring (6) is provided with a support projection (10) which is rounded off at the end towards the connecting fitting and which is of a tapered configuration along its outside periphery, while the associated connecting fitting (3) comprises the end of the injection line (1) which is flanged over outwardly about the support projection (10) and there forms th

Abstract: A pipe clip comprising resilient material which comprises a mounting portion (1) with at least two clamps (3, 4) having clamping limb portions (3a, 3b; 4a, 4b) which can be resiliently spread open for the insertion of conduits (2), the clamps being adapted to the conduit cross-section. The clip has at least one stirrup portion (6) which engages over the clamps and which in its closed position snaps, with inner catches (7a, 9a) disposed on its two elastically spreadable limbs (7, 9), behind associated catches (3d, 4d) on the two mutually oppositely disposed outermost clamping limb portions (3a, 4b) of clamps (3, 4) which are arranged in side-by-side relationship in one plane. The stirrup portion is provided at each intermediate space between two clamps which are covered over thereby in the closed position thereof, with a bar portion (12) which in the closed position engages between said clamps and thereby resiliently spreads apart the two clamping limb portions (3b, 4a) which are most closely adjacent thereto.

Abstract: A lifting keel assembly for sailboats having a shaft obliquely inclined in forward and upward directions slidably receiving the lifting keel, the upper area of the lifting keel being provided with sliding shoes on the forward and rearward longitudinal edges, which sliding shoes are guided in associated prismatic guides of the shaft, one sliding shoe having on either side a protruding V-profile, and the associated guide enclosing said two V-profiles of the sliding shoe, while a further sliding shoe on the other edge of the keel is guided in an associated guide by two oppositely arranged sliding surfaces.
