Pressure medium control system for auxiliary power steering systems |
摘要 |
Precise control over outlet pressure as a function of valve position is obtained for operation of a servomotor by a rotary plug valve journaled at opposite ends in a control bushing having conduit channels in fluid communication with passage grooves in the plug valve to form a plurality of parallel flow paths between a pressure inlet and two directional outlets to the servomotor. The edge formed on the plug valve by a passage groove in only one of the parallel flow paths to each of the outlets is beveled to improve valve control precision.
