Abstract

A hydraulic system for a motor vehicle has at least one pressure restricting valve with a housing that has two or more connections. At least one conduit cross-section in the housing can be closed by means of a closing body that is movable axially against the action of an energy accumulator. At least a part of the axial travel of the closing body is damped by means of a damping device.
