Abstract
A hydraulically controlled storage chamber valve includes a closing element that is biased via a first compression spring. The closing element seals a valve seat in a valve body. A tappet protrudes through a bushing in the valve body and is movable by an accumulator piston that is loaded by a second compression spring that is configured to push the closing element out of the valve seat when a specified force ratio is present between spring bias forces and a hydraulically acting force. The tappet is fastened in a region of the bushing such that the tappet is movable in a longitudinal direction and lies flush with a face of the accumulator piston while moving.
