Title: Connection system for pipelines
Inventor: LEHMANN KLAUS D
IPC: F16L19/12
Filed: 1993-02-16
Abstract: In order to increase the pipe-retaining force and/or the possible operating pressures of a pipe-connection system, the profile ring or rings which holds or hold the pipe to be connected are made not of a surface-hardened material, but of a material which is strengthened or hardened throughout and, in this arrangement, is expediently provided, downstream of a metallically pre-sealing region with rounded edges, with a coating which reduces the friction and optimises the sealing. In the front region of the profile ring, first of all a metallic contact with respect to the screw-connection body is produced, thus preventing coating materials being able to flow to the medium side and, in the rear region, the pressing of the ring shoulder onto the pipe as radial loading support is made possible by an angle difference between the shoulder and tightening-nut pressure-exerting surface.

Filed: 1993-07-20
Abstract: Pneumatic control device for hot runner needle valves for injection moulds, which control device comprises a control piston (1), bearing the valve needle (10), a control cylinder (2) receiving the control piston, and a cylinder-receiving element (3), receiving the control cylinder. The control cylinder (2) is provided with compressed-gas channels (25a, 25b) for feeding and removing compressed gas to and from the cylinder chambers (4a, 4b) separated by the control piston. According to the invention, the control cylinder (2) can be pressed by one of its end faces (21) via seals (26a to 26c) against a contact surface (32) of the cylinder-receiving element (3), the seals (26a to 26c) bounding two mutually separate channel chambers (28a, 28b). The control cylinder (2) is displaceable on the contact surface (32) perpendicularly with respect to the piston longitudinal axis (b). Into each channel chamber (28a, 28b) there opens out a compressed-gas line (33a, 33b), leading through the cylinder-receiving element and for feeding and removal of the compressed gas, and from each channel chamber (28a, 28b) there leads a compressed-gas channel (25a, 25b), running in the axial direction, through the wall of the control cylinder (2) to a cylinder chamber (4a, 4b). The invention makes it possible for constraint-induced transverse forces on the valve needle (10) to be eliminated by the cylinder with the pistons for lateral displacement. <IMAGE>

This mounting wall is, for its part, a component of a cable duct in whose interior the installation box can be mounted by means of holders which can be fixed to the hook projections and overhang the base of the box underneath. In order to be able to leave out the supporting ring which is generally present in installation apparatuses and to omit the apparatus fastening screws in the installation boxes it is proposed to design the holding means for the installation apparatus as a latching element which is integrally formed on one of the inner walls of the intallation box lower part and forms a connection, which can be detached only by means of a tool, with a mating catch on the installation apparatus. In the case of the preferred embodiment, the latching element is integrally formed on the inner surface of the base of the installation box lower part.
