PROBLEM TO BE SOLVED: To improve a conventional hydraulically controlled accumulator-chamber valve.SOLUTION: A hydraulically controlled accumulator-chamber valve includes a closing element 40 which is pre-biased via a first compression spring 14 to seal a valve seat 36 in a valve body 32, and a tappet 22 which reaches through a through part 35 in the valve body 32, and can be moved by an accumulator piston 10 biased by a second compression spring in order to press the closing element 40 out of the valve seat 36 when there is a specified force relationship between the spring pre-biasing forces and a hydraulically active force. In order to guide the tappet 22 in the through part 35 in a longitudinally movable manner, the closing element 40 and the tappet 22 are formed as a single-piece member. The tappet 22 is abutted on an end face of the accumulator piston 10 during the valve opening movement. |
