Abstract

An electromagnetically actuated valve, in particular a pressure control valve of a slip-controllable vehicle brake system, includes a seat body with a valve seat, at least one inflow channel, and an outflow channel. The valve includes a shut-off element configured to avoid a hydraulic short circuit between the inflow channel and the outflow channel when the valve seat is closed. The shut-off element is equipped with flow-directing means. The flow-directing means prevent the partial flows from the inflow bores from hitting each other and direct the flow to a closing body, which controls the valve seat, in such a way that a transverse force is applied to the closing body when the closing body performs a stroke motion. The transverse force radially deflects the closing body during an opening or closing motion and causes an effect that stabilizes the stroke motion and dampens radial vibrations.
