ABSTRACT:
An air spring assembly is connected to a member in the form of a cover, door or panel for movement between a position at which the member closes an opening and a position at which the member is removed from the opening. The member is movable between limit positions and the air spring assembly assists in movement. If any portion of the original charge attained by the air spring is lost due to leakage, the air spring assembly is automatically charged during movements of the member so that a piston rod is able to exert a predetermined force on the member.
