Abstract

Official abstract text for this publication.

A braking device for a vehicle, in particular a motor vehicle, including an actuatable brake pedal, a piston of a master brake cylinder mechanically coupled to the brake pedal, the piston being supported in the master brake cylinder so as to be axially displaceable in an actuation direction and in a release direction, and including at least one radial seal that acts between the piston and the master brake cylinder. At least one elastically deformable and/or displaceable damping element opposes the displacement of the piston in the release direction.

First claim

Opening claim text (preview).

What is claimed is: 1. A braking device for a motor vehicle, comprising: an actuatable brake pedal; a piston of a master brake cylinder that is mechanically coupled to the brake pedal, the piston being supported in the master brake cylinder so as to be axially displaceable in an actuation direction and in a release direction; and at least one radial seal that acts between the piston and the master brake cylinder; and a damping element which is at least one of: (i) elastically deformable, and (ii) displaceable, the damping element opposing displacement of the piston in the release direction, wherein the damping element is situated at an unattached end of a rocker arm, the unattached end being pretensioned by a spring element against an outer peripheral wall of the piston. 2. The braking device as recited in claim 1 , wherein the damping element is pretensioned by spring force against an outer peripheral wall of the piston. 3. The braking device as recited in claim 1 , wherein the at least one radial seal is elastically deformable. 4. The braking device as recited in claim 1 , wherein the damping element is outside of the master brake cylinder. 5. A braking device for a motor vehicle, comprising: an actuatable brake pedal; a piston of a master brake cylinder that is mechanically coupled to the brake pedal, the piston being supported in the master brake cylinder so as to be axially displaceable in an actuation direction and in a release direction; and at least one radial seal that acts between the piston and the master brake cylinder; and a damping element which is at least one of: (i) elastically deformable, and (ii) displaceable, the damping element opposing displacement of the piston in the release direction, wherein the damping element is a pneumatic non-return valve that seals a pressure chamber surrounding the piston and is comovable with the piston.
