Document Type and Number:
Japanese Patent JP3179106
Kind Code:
B2
Abstract:
A rotary slide valve (1) for power-assisted steering systems of motor vehicles contains a rotary slide (2) that is guided in a limited rotary fashion in a control box (3). Control box (3) is connected with a valve exit member (7) in a nonrotating manner. Rotary slide (2) is connected with valve exit member (7) via a torsion rod (9) and a dead-travel clutch (10). Dead-travel clutch (10) consists of a catch section piece (16) of the valve exit member (7) and of recesses (17) that are fashioned on the free end of rotary slide (2). Rotary slide (2) with its longitudinal control grooves (12, 13) and with its recesses (17) is made by way of a noncutting production process. This production process is simplified and the rotary slide valve (1) is made smaller in that the recesses (17) of rotary slide (2) are arranged in longitudinal control grooves (13) of rotary slide (2) that are open toward one end.
