Claim Text:
1. A gas spring and gas damper assembly comprising: a first end member; a second end member disposed in longitudinally-spaced relation to said first end member; a flexible wall operatively connected between said first and second end members such that a spring chamber is at least partially defined therebetween; a damping chamber wall disposed within said spring chamber in longitudinally-spaced relation to said first and second end members, said damping chamber wall at least partially defining a damping chamber; and, a damper piston disposed within said damping chamber such that a first portion of said damping chamber is formed along one side of said damper piston and a second portion of said damping chamber is formed along an opposing side of said damper piston, said damper piston operatively connected to said second end member and capable of reciprocal movement within said damping chamber in an approximately longitudinal direction; a first fluid passage disposed in fluid communication with said first portion of said damping chamber; and, a second fluid passage disposed in fluid communication with said second portion of said damping chamber; one of said first fluid passage and said second fluid passage disposed in fluid communication with an external atmosphere with the other of said first fluid passage and said second fluid passage disposed in fluid communication with said spring chamber such that upon displacement of said gas spring and gas damper assembly between an extended condition and a compressed condition, said damper piston can undergo reciprocal movement within said damping chamber and thereby dissipate kinetic energy acting on said gas spring and damper assembly.
