A noise damper for a compressed air device includes a tubular housing part provided with an air inlet and an inserted insulating material, in particular, an inserted knitted fabric roll. The air inlet is embodied in the envelope of the tubular housing part such that the supplied air tangentially flows through the insulating material or the knitted fabric roll, is radially deviated inside the tubular housing part, and axially flows out from at least one end of the tubular housing part.

An actuating device for a brake unit of a vehicle EBS includes a tappet positioned in a housing of the brake unit for actuating a piston to operate a brake valve. A displacement sensor slide measures axial movement of the tappet. So that moving parts of the actuating device are guided with minimal friction and that torque acting on the tappet is compensated for, the tappet includes a base plate disposed non-rotatably in a receiver of a guide ring having spaced-apart oblong holes, a spacer ring disposed in the guide ring having angled edges which extend into the oblong holes, and a window on the guide ring protruding radially outwardly into a slit on the housing to receive the displacement sensor slide.

An actuating device for a brake unit of a vehicle EBS includes a tappet positioned in a housing of the brake unit for actuating a piston to operate a brake valve. A displacement sensor slide measures axial movement of the tappet. So that moving parts of the actuating device are guided with minimal friction and that torque acting on the tappet is compensated for, the tappet includes a cylindrical attachment having a bottom with holes and a shell, a groove on the outer surface of the shell having openings, a spacer ring in the cylindrical attachment between the tappet and the piston having projections which extend into the holes, a guide ring in the groove having raised portions on its inner surface which extend into the openings and a window on its outer surface protruding through an opening into a slit on the housing to receive the displacement sensor slide.

The present invention provides an apparatus for recording the axial force exerted by a coupling device. This apparatus measures the pressure which the axial force exerts on an elastomer-type spring-like element and for this purpose a pressure sensor is mounted at a predetermined transfer shoulder between the elastomer-type spring-like element and the housing or the pull rod of the coupling device. As an alternative, the pressure sensor can be mounted in the elastomer-type spring-like element.
