摘要： A hydraulic shock absorber having discrete damping levels in the rebound direction includes a piston that reciprocates within a pressure tube and divides the pressure tube into rebound and pressure chambers. A passage extends through the piston for establishing fluid communication between the rebound and pressure chambers. A one-way, pressure responsive valve normally closing the passage opens in response to fluid pressure of a predetermined magnitude in the rebound chamber when the piston moves in the rebound direction. The side wall of the pressure tube has bleed holes that lead to a bypass channel that is controlled by an electronically controlled or actuated solenoid valve that opens and closes the outlet of the bypass channel to change the damping characteristics in the rebound and jounce directions in response to suspension conditions. The piston carries a slide valve that closes the bleed holes to the bypass channel mechanically in the rebound direction in response to rapid changes in suspension conditions that the solenoid valve cannot react to quick enough.

摘要： In a vibration damper for a motor vehicle a flow path connecting a working chamber of the cylinder with a damping behavior control unit is confined by a flow path tube surrounding the cylinder. The flow path tube is provided adjacent its axial end portions with bead-shaped grooves accommodating respective sealing rings. These sealing rings are according to an illustrated example of the invention in engagement with an external surface of the cylinder. The bead-shaped grooves are obtained by non-cutting machining.

摘要： Pneumatic spring, comprising a spring bellows acting as a rolling bellows, whereby the spring bellows borders a spring chamber filled with gas under pressure. The gas is supplied to the spring chamber by means of a pressure connection, whereby the spring bellows is connected on one hand to an axially-movable outer tube, and on the other hand via a roll-off tube. The roll-off tube is engaged with a spring bracket, and the roll-off tube, together with a mounting device on the spring bracket, forms a locking connection which locking connection defines the axial position of the roll-off tube.
