Abstract
Apparatus for converting heat derived from a heated fluid into mechanical energy comprising a double-walled shell having a high coefficient of thermal expansion and other preferred qualities, such as a relatively high coefficient of heat conductivity and low specific heat, the shell being immersed in a fluid within a container having a relatively low coefficient of thermal expansion and other qualities. When heated fluid is passed between the walls of the shell, expansion of the latter displaces fluid from within the container to actuate a fluid operated device. Alternatively, passage of a cold fluid between the walls of the shell causes the shell to contract and thus enable the displaced fluid to return into the container to complete an operating cycle.
