Abstract
A damping apparatus including a piston having an axis therethrough. The piston includes a coaxial body portion and a first and second end extending oppositely therefrom along the axis. A rigid housing is coaxial with and surrounds the body of the piston for forming a rigid fluid volume between the piston and the rigid housing. The rigid fluid volume includes a first fluid chamber at a first end of the piston and a second fluid chamber at the second end of the piston. The first and second fluid chambers are connected by a damping path. The damping apparatus further includes a flexible housing coupled to the first and second ends of the piston and surrounding the rigid housing to form a fluid return of lower resistance to flow than the damping path between the rigid housing and the flexible housing and to allow movement of the rigid housing with respect to the piston. The rigid housing forms a first and second restrictive path about the first and second ends of the piston, respectively, of higher resistance to flow than the damping path to allow fluid to flow between the fluid return and the rigid fluid volume.
