Patent DE-3902808-A1 (DE)
Title: Hydraulic power steering system
Inventor: ELSER DIETER
IPC: B62D5/06
Filed: 1989-01-31
Abstract: The invention relates to a pressure cut-off device at the limit positions of the steering lock in a power steering system. In steering systems which have a working piston (2) which can be displaced in the steering housing, this cut-off device is built into a through-hole (17) of the working piston (2). A cut-off valve (20, 22 and 21, 23) which can be actuated by a plunger (24 and 25) which runs up against the wall (30 and 31) is provided for each steering direction. In order to avoid time-consuming adjustment operations of the cut-off valves (20, 22; 21, 23), the walls (30 and 31) contain bushings (32 and 33) which are located opposite the plungers (24 and 25) and which, after installation of the power steering system into the vehicle, can be pressed automatically into the limit positions corresponding to the wheel steering angle. This takes place in that, after the prefitting of the bushings (32, 33) in their holes (26 and 27) with the front axle jacked up, the system is steered towards the wheel stops initially without power steering. During this process, the bushings (32 and 33) are pressed in by the working piston (2) to the degree (a) provided for switching off the power steering. Since the plungers (24 and 25) of the cut-off valves (20, 22; 21, 23) are larger, by the amount (x) than the depth (s) of the hole of the bushings (32 and 33), the power steering switches off just before the wheel stops are reached. <IMAGE>

Abstract: In mfg. light wave guides, through coating the interior of a glass tube, a flow of gas and vapourising reactants is formed into a flat layered flow before entering the interior coating zone of the glass tube, and cover the surface through a chemical vapour phase reaction. The flow is pref. given a flat and layered structure through an entry tube with the same inner dia. as the glass tube and of sufficient length to smooth the flow, and the entry tube can be fitted with an insert to control the flow pattern. The reactant flow is heated before it enters the glass tube.

The flow is fed (8,9) into the end of the entry tube (5) away from the glass tube (1). The glass tube (1) coupling piece (6) and entry tube (5) are all rotated together round the longitudinal axis. An insert can be fitted to the entry tube (5) to bring the flow into a flat and layered form. A stationary heating unit can be located before the opening into the glass tube to raise the flow temp. before it enters the section of the tube interior to be coated. ADVANTAGE - The method gives an even deposition along the length of the glass tube.
