Rotary slide valve for powered steering systems of motor vehicles has arrangement allowing return of fluid from longitudinal control slot of radially inner valve element to return connection through needle bearing |
摘要 |
<p>The return of fluid from the longitudinal control slot (8) of the radially inner valve element to the return connection (18) takes place through a rolling bearing (14) in the form of a needle bearing. A torsion rod spring (12) is fitted in the inner cavity (13) of the inner valve element and is mounted in the needle bearing. The needle bearing has a needle cage (15) with a cross section conducive to free flow and has passages which allows flow of return fluid without any pressure drop.</p> |
