HYDRAULICALLY CONTROLLED ACCUMULATOR-CHAMBER VALVE

摘要

A hydraulically controlled accumulator-chamber valve has a closing element and a tappet. The closing element is prestressed via a first compression spring and seals a valve seat in a valve body. The tappet reaches through a leadthrough in the valve body and is moved by an accumulator piston. The accumulator piston is loaded by a second compression spring. The tappet is moved to press the closing element out of the valve seat when there is a specified balance of forces between the spring prestressing forces and a hydraulically active force. The closing element and the tappet are configured as a single-piece component, in order to guide the tappet in the leadthrough in a longitudinally movable manner. The tappet bears against an end face of the accumulator piston during an opening movement.
