Abstract

A valve device includes a valve body that forms a throttle cross section and a valve element that sets the throttle cross section depending on the pressure. To avoid pulsation-induced noises, the valve element is configured with a flow-deflecting member that causes action upon the valve element with a transverse force. The flow-deflecting member prevents noise-causing vibrations of the valve element and permits a lower throttling effect of the valve device, in particular when volumetric flows are increased. A damping device, in particular for damping pressure pulsations in a brake circuit of a slip-controllable vehicle brake system, includes the valve device.
