Abstract:
Housing has first and second parallel tubular chambers. The first chamber contains a gas spring whose output shaft connects to a first piston of area A 1 . The second chamber contains a second piston of area A 2 <A 1 . Piston A 2  connects to the device's output shaft. The housing has a valve block at one end with an internal port in fluid communication with the volumes of the two chambers that are between the first and second pistons and the valve block containing an incompressible fluid. A spring-biased poppet valve is contained in the internal port. The poppet includes a flow restricting bore therethrough. A force on the output shaft causes the fluid to force open the poppet and displace the piston, A 1 , to store energy in the gas spring. Upon removal of the force on the device's output shaft, the gas spring pushes the fluid to close the poppet. Hence, only a low volume flow through the bore in the poppet is permitted to dampen output shaft movement.

Claim (Index 3):
The combination air spring and damper of  claim 1  and further including first and second tubular sleeves respectively disposed in the first and second tubular chambers of the body member, the tubular sleeve in the second chamber being in surrounding relation with respect to the gas spring and first piston and the tubular sleeve in the first chamber being in surrounding relation to the second piston.
