ABSTRACT:
A method and apparatus for protecting a relatively low temperature rated pressure seal from a relatively high temperature gas residing between a cylinder head and its associated piston. A low temperature rated pressure seal as for example an elastomeric seal is protected from high temperature gas in a heat engine, potentially in excess of 2,000.degree. F. (1093.degree. C.) by the use of an intermediary fluid that is trapped in a reservoir in the head of the cylinder said seal being maintained in a liquid fashion by a skirt extension from the head of the piston into the reservoir holding the described liquid, the intermediary liquid also being in contact with the elastomeric seal in the space between the piston and the cylinder. Additionally a heat engine operating at high efficiency utilizing the seal above described in order to maximize efficiency while eliminating leakage and loss of pressure, said heat engine deriving much of its temperature by an economizer that is a counterflow heat exchanger and from external secondary heating sources in constant volume expansion steps.
