Electrohydraulic valve i.e. pressure regulating valve, washing method for motor vehicle, involves moving closing unit from stroke path till final stroke path that is smaller than stroke path of unit and larger than aperture width of insert

摘要

The method involves adjusting a closing unit (34) around a stroke path for washing a pressure regulating valve (10), where the stroke path is formed by an adjusted distance of a front side (42) of the closing unit from a laminar seat (44). The closing unit is moved from the stroke path till a final stroke path that is smaller than maximally adjustable stroke path of the closing unit and larger than a width of an aperture of a filter insert (62).
