Abstract
This invention relates to the field of internal combustion engines and compressors in general and to linear compressors, in particular these used as in U.S. Pat. No. 8,056,527, by accurately controlling the pressure being delivered into the combustion chambers of said engine while returning unused energy of the compression phase into the motor for complete expansion. Another improvement relates to a pressure compensated vane to be used inside grooves of the motor assembly rotor. This invention enables the vane to seal against the cavity of the housing tightly with minimal force.
Claims17
A split-chamber rotary engine improvement comprising:
- a motor assembly, one or more compressor assemblies, and one or more variable pressure controllers.
A split-chamber rotary engine improvement comprising:
- an improved motor assembly that has pressure compensated vanes inserted into its rotor.
A split-chamber rotary engine improvement comprising:
- a cam or a pair of fixed cams that will be ridden by the lower roller of the vane assembly as the rotor turns, moving the vane assemblies in and out of the rotor grooves as required by the housing cavity.
