STEUERUNGSVENTIL

摘要

This invention relates to a control poppet valve assembly wherein the outer poppets are precisely adjustable with respect to the spacing from the central poppet thus enabling the use of bevelled seating surfaces in a valve of this type. Such surfaces reduce the likelihood of foreign bodies disturbing the seating integrity of the valve. The invention also involves a system for actuating the valve either by a solenoid control or a manually-activated override control.
