Continuously adjustable valve for hydraulic control arrangement of e.g. hydraulic motor, has valve portion with valve seat in movable control section so that control section is abutted to interrupt pressure medium volume flow

摘要

The valve (23) has a housing-fixed control section that is extended in axial direction. A movable control section is moved in axial direction along the fixed control section. A first set of transit recess portion is passed transversely to axial direction from fixed control section. The cross-sectional area of openings of recess portion is adjustably covered by movable control section. The valve portion (58) is provided with a valve seat in the movable control section, so that the movable control section is abutted to interrupt the pressure medium volume flow. An independent claim is included for a hydraulic control arrangement.
