Patent number: 5322142Abstract: This invention relates to a pressure turnoff device in the terminal positions of the steering deflection in an auxiliary power steering. In steering systems that reveal a working piston (2) that can be shifted in the steering housing, one inserts this turnoff device in a passage borehole (17) of working piston (2). For each steering direction, one provides a turnoff valve (20, 22 or 21, 23) which can be activated by a plunger (24 or 25) that bumps into a wall (30 and 31). To avoid any time consuming adjustment work on the turnoff valves (20, 22; 21, 23), the walls (30 and 31) contain screwed-in bolts (40 and 41) with pressed-on sleeves (32 and 33), with the sleeves working as stops. After installation of the auxiliary power steering in the vehicle, one can automatically press the sleeves (32 and 33) into the terminal position corresponding to the wheel steering angle.Type: GrantFiled: February 9, 1993Date of Patent: June 21, 1994Assignee: ZF Friedrichshafen, AG.Inventor: Dieter Elser
