The improved system for liquid cooling of a rotor of a rotary piston mechanism applies to those types having two housing walls spaced apart by a trochoidal shaped peripheral wall to define a multi-lobed cavity within which a multi-cornered rotor is eccentrically supported for planetary movement, and in which the rotor has a hub portion and peripheral wall portions defining therebetween cooling spaces which communicate with the area exteriorly of the rotor through an opening adjacent each end of the hub portion. The improved rotor cooling system comprises a cooling liquid discharge nozzle disposed in at least one of the housing walls and connecting the discharge nozzle to a source of pressurized cooling liquid. The discharge nozzle is positioned so as to direct emitted cooling liquid into the adjacent rotor opening and the cooling spaces in the rotor. In a narrower aspect of the invention a regulator and valve assembly is provided to control flow of cooling liquid to the discharge nozzle in accordance with the pressure conditions of the cooling liquid and temperature and load operating conditions of the engine.
In a rotary piston mechanism having a housing comprising two housing walls spaced apart by a peripheral wall to define a multi-lobe, trochoidal-shaped cavity and a rotor eccentrically supported for planetary movement within said cavity and which rotor has a hub portion and peripheral wall portions defining cooling spaces therebetween which communicate with the area exteriorly of the rotor through an opening adjacent each end of the hub portion, an improved rotor cooling system comprising:
In a rotary piston mechanism having a housing comprising a plurality of cavities each of which is defined by at least one intermediate wall, a peripheral wall of trochoidal configuration and an end wall, a rotor supported on an eccentric portion of a mainshaft within each cavity so that the rotor planetates within its associated cavity, the mainshaft being supported to extend through an opening in the intermediate wall, each of said rotors having a hub portion and peripheral wall portions to define therebetween a plurality of cooling spaces which communicate with the opening in the intermediate wall through an opening in the rotor adjacent the hub portion and said intermediate wall opening, an improved rotor cooling system comprising:
