Abstract
A rotary mechanism including a housing defining a chamber, a shaft journalled in the housing to extend through the chamber and having an eccentric within the chamber, a rotor within the chamber and journalled on the eccentric, the rotor having surfaces cooperating with the housing to vary the volume of at least one portion of the chamber upon rotation of the shaft, the rotor and the housing relative to each other, coolant receiving cavities in the rotor adjacent the surfaces, a source of coolant for the cavities, and agitators within the cavities and movable therein for cyclically displacing the coolant to enhance heat transfer.
Claims10
In a rotary mechanism, the combination of:
- a housing defining a chamber;
- a shaft journalled in said housing to extend through the chamber and having an eccentric within the chamber;
- a rotor within the chamber and journalled on said eccentric, said rotor having surfaces cooperating with said housing to vary the volume of at least one portion of the chamber upon rotation of said shaft, said rotor and said housing relative to each other;
- coolant receiving cavities in said rotor adjacent said surfaces;
- means for directing coolant to said cavities;
- and
- agitators loosely disposed within said cavities to be movable with the rotor and to be movable within the cavities for cyclically displacing the coolant to enhance heat transfer.
A slant axis rotary mechanism comprising:
- a housing defining a chamber having radially inner and outer spherical walls interconnected by spaced, generally radially extending, opposed end walls;
- a shaft journalled in said housing and having an angularly offset eccentric within said chamber;
- a rotor having a spherical hub and a radially outwardly extending peripheral flange in said chamber and journalled on said eccentric;
- coolant receiving cavities within said flange;
- means for directing a coolant to said cavities;
- and
- agitator bodies formed of a material having a higher density than that of the coolant loosely received in said cavities.
