Abstract
A rotary engine having a high surface to volume ratio including a housing having intake and exhaust ports and defining a chamber, a shaft journalled in the housing to extend therethrough and having an eccentric within the chamber, and a rotor on the eccentric within the chamber, the rotor having a body consisting essentially of a material having a low coefficient of thermal conductivity.
Claims3
In a rotary engine having a high surface to volume ratio, the combination of:
- a housing having intake and exhaust ports and defining a chamber;
- a shaft journalled in the housing to extend through the chamber and having an eccentric within the chamber;
- a rotor journalled on said eccentric within said chamber, said rotor having a body consisting essentially of a ceramic material;
- seals carried by said rotor sealingly engaging the walls of the chamber;
- and
- metallic, grooved inserts in said rotor body for receiving the seals in the groove thereof, means placing said insets in tension so that said body is in compression.
