Class Information
Number: 60/517
Name: Power plants > Motor operated by expansion and/or contraction of a unit of mass of motivating medium > Unit of mass is a gas which is heated or cooled in one of a plurality of constantly communicating expansible chambers and freely transferable therebetween
Description: Apparatus in which the unit or working medium is a gas which is confined to circulation between two communicating expansible chambers, one of said expansible chambers is a working chamber wherein said gas expands or contracts to energize a working member to do useful work, and the other of the expansible chambers acts as a displacer or transmitting means for said working medium.
