Claim:
1. A pneumatic spring strut assembly comprising: a cylinder wall defining and interior volume having a working end and a boosting chamber adjacent to the working end, the working end including a first volume of gas and the boosting chamber including a second volume of gas; a piston assembly disposed for reciprocation in the working end of the interior volume, a piston rod having a proximal end secured to the piston assembly and a distal end projecting out of the interior volume; and a temperature control valve (TCV) assembly disposed in the interior volume separating the working end from the boosting chamber, the TCV assembly including a valve member responsive to changes in temperature to selectively fluidically connect the working end and the boosting chamber, and an engineered portion that is configured to prevent fluid flow between the working end and the boosting chamber while the first volume of gas is present in the working end and to yield permitting fluid flow from the boosting chamber to the working end should the working end be evacuated of the first volume of gas.
