Abstract: An example vibration tolerant damper includes an outer tube, a shaft received within the outer tube, and a piston valve received within the outer tube. The shaft moves together with the piston valve as the shaft extends and retracts through a first range relative to the outer tube. The shaft moves independently from piston valve as the shaft as the shaft extends and retracts through a second range relative to the outer tube.

Abstract: A gas spring assembly is used to control movement of a vehicle body panel relative to a vehicle body member. The gas spring assembly includes a rod and piston that are received within a tube or cylinder. A first rod end is coupled to the piston to move the piston back and forth within the cylinder. A second rod end is mounted to one of the vehicle body panel or the vehicle body member. The cylinder is mounted to the other of the vehicle body panel or the vehicle body member. The gas spring assembly includes a resilient cover that covers the rod and cylinder and extends from the second rod end to a distal cylinder end. The resilient cover extends and retracts with rod movement and is sealed at each end of the resilient cover to provide a completely sealed gas spring assembly.

Abstract: An improved gas spring has a drive motor for driving a piston. A piston head has a thread at an outer periphery that is guided along a mating thread in an inner periphery of a cylinder. The piston is caused to rotate relative to the cylinder, and is guided for reciprocating movement. In this manner, a drive motor is incorporated into the gas spring such that the gas spring has both a driven and a manual mode. The inventive gas spring has particular application in attaching a vehicle closure to a vehicle frame.

Abstract: A gas spring is mounted through a unique mount structure including a socket joint. The socket joint is mounted in a yoke for rotation through 180° about an axis of the yoke. The inventive structure provides greater freedom of movement than the prior art, and in many applications will allow rotation for more than 180°.
