Class Information
Number: 60/519
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 > Expansible chamber having rotatable or oscillatory displacer
Description: Apparatus in which at least one of said expansible chambers is provided with a member which either rotates or oscillates about an axis so that said chamber either expands or contracts as a result of motion of said member.
