Electrical contact system for controlled vibration damper - has connecting wires from solenoid valve built into piston brought out through piston rod via contact sleeve with contact pads
An electrically controlled vibration absorber for use on road vehicle systems has a cylinder (4) with a piston (11) and a coupled piston rod (12). Built into the piston body is a solenoid valve (40) that is operated to control the flow of hydraulic fluid through a channel (38) and in doing so varies the damping action. The electrical connections (41) to the valve are brought through the piston rod and a contact bush (55). The contact bush has spring-loaded contact pins (64) that engage contact rings (70). The connecting wires (78) are brought out through the piston rod. USE/ADVANTAGE - Allows number of connections to be made through piston rod.
