Control valve, in particular an electrohydraulic control valve

摘要

A control valve, in particular, an electrohydraulic control valve for controlling the injection pump of a diesel engine, incorporates a slider which is guided in a housing, in a manner permitting movement in the axial direction, the housing possessing radial flow-ports and, in the region of the inner peripheral surface, at least one annular space carrying a fluid. In order to ensure that the control-valve housing can be manufactured economically, the annular space is formed by a plurality of flow-ports which intersect in the region of the inner peripheral surface of the housing and pierce the housing radially.
