摘要

An ejector piston slides in a control sleeve mounted in a cylindrical housing. Inlet and outlet opening of the control sleeve are offset with respect to the feed and discharge openings of the housing. Depending on the end position of the control sleeve with respect to the housing, either the feed opening and the inlet or the discharge opening and the outlet coincide. The control sleeve pref. contains a metering chamber the volume of which depends on the stroke of the ejector piston.
