Continuously variable single-tube shock absorber with bidirectional control valve
First Claim
1. Continuously variable single-tube shock absorber with bidirectional control valves, comprising:
- a working cylinder;
a piston which is connected to a piston rod and is movable in the working cylinder;
openings cut out in the piston;
spring-loaded shock absorber valves fitted on either side of the piston, in order to shut off said openings until a certain fluid pressure has been reached;
exciting chambers situated on either side of the piston, each bounded by a stationary disc, a piston skirt which can be slid around said disc, and two spring-loaded plates;
wherein said exciting chambers are in communication with a communicating bore in which the pressure is controlled by a control mechanism;
wherein said communicating bore through which fluid can flow into the exciting chambers are provided in said stationary disc; and
wherein each spring-loaded plate is clamped near the piston rod and rests with initial stress against an edge of said piston skirt.

Abstract
A continuously variable single-tube shock absorber operating according to the skyhook principle and having bidirectional control valves comprising a working cylinder, a piston with piston rod which is movable therein, openings cut out in the piston, spring-loaded shock absorber valves, fitted on either side of the piston, in order to shut off the openings until a certain fluid pressure has been reached, exciting chambers fitted on either side of the piston and each bounded by a stationary disc, a piston skirt which can be slid around such a disc, and a spring-loaded shock absorber valve. The exciting chambers are in communication with a bore in which the pressure is controlled by a control mechanism. Bores through which fluid can flow into the exciting chambers are provided in the stationary discs. The control mechanism can consist of a movable mass which is fitted in a spring-loaded manner and controls the passage of fluid to a bore which is in communication with the exciting chambers, or it can consist of valves to be adjusted by a coil.

6. Continuously variable single-tube shock absorber with bidirectional control valves, comprising:
-
a working cylinder;
a piston which is connected to a piston rod and is movable in the working cylinder;
openings cut out in the piston;
spring-loaded shock absorber valves fitted one either side of the piston, in order to shut off said openings until a certain fluid pressure has been reached;
exciting chambers situated on either side of the piston, each bounded by a stationary disc, a piston skirt which can be slid around said disc, and two spring-loaded plates;
wherein said exciting chambers are in communication with a central bore in which the pressure is controlled by a control mechanism;
