Abstract
The invention provides a damper assembly ( ) comprising a housing ( ) defining an inner chamber ( ) having a damping fluid disposed therein. A piston rod ( ) is slidably retained by the housing ( ), and at least partially extends into, the chamber ( ). A piston ( ) is disposed at a first distal end ( ) of the piston rod ( ) and strokes inside the housing ( ). The piston ( ) defines a first chamber ( ) and a second chamber ( ) within the housing ( ) and includes at least one aperture ( ) for allowing damping fluid to flow between the first ( ) and second ( ) chambers. An actuator ( ) is disposed within the piston ( ) for varying the flow of damping fluid through the aperture ( ) between the first ( ) and second ( ) chambers within the housing ( ). The piston rod ( ) includes an inner bore ( ) that receives pressurized air from an external source for communicating pneumatic control signals to the actuator ( ).
