Control apparatus for connection of two-pressure medium impact type set machine, has movement piston with effective piston area which is set smaller than front surface of opposing of main control slide

摘要

A movement piston (63) has an effective piston area which is set smaller than the front surface of the opposing of a main control slide (26). A pressure room (62) leads a flow path (67) placed into a casing (25), so that the pilot control valve (43) is operated according to the control signal. An operation unit (2) is allocated to the main valve slide with adjustment unit (60,61). An independent claim is also included for a pressure medium source.
