Abstract
A radial internal combustion engine having a rotor of the radially movable vane type eccentrically housed within a rotor chamber casing both of which are journalled for rotation within an engine housing. Combustion induced rotation of the rotor is coupled by a gear train to the rotor chamber casing for driving the rotor chamber casing at the same speed as the rotor. Impeller blades provided on the periphery of the rotor chamber casing are employed to supercharge the fuel mixture prior to its being directed into the volumetrically expandable and contractable combustion chambers provided about the periphery of the rotor.
Claims10
A rotary internal combustion engine comprising:
- (a) an engine housing including,
- I. a main body portion having a bore which forms a rotation chamber,
- II. an end plate mounted on one end of the main body portion for closing thereof, said end plate having a fuel inlet passage formed therethrough for receiving a fuel mixture from an external supply thereof and directing it into the rotation chamber, said end plate having an exhaust port formed therethrough through which spent exhaust gases exit said engine housing,
- III. a fuel porting partition mounted at the opposite end of said main body portion and having a first plurality of fuel transfer ports formed therethrough which are disposed to lie in spaced increments on a circular centerline adjacent the periphery of said fuel porting partition and having a second plurality of fuel transfer ports formed therethrough which are disposed to lie in spaced increments about a circular centerline of reduced diameter,
- IV. a support partition mounted on the opposite end of said main body portion with said fuel porting partition interposed therebetween, said support partition configured to provide a fuel induction chamber between said fuel porting partition and said support partition, said fuel induction chamber for receiving the fuel mixture from said rotation chamber through the first plurality of fuel transfer ports of said fuel porting partition and directing the received fuel mixture into said second plurality of fuel transfer ports of said fuel porting partition,
- V. an end cover mounted on the opposite end of said main body portion with said fuel porting partition and said support partition interposed therebetween, said end cover configured to form a chamber between said support partition and said end cover;
- (b) a rotor chamber casing having a rotor chamber therein, said rotor chamber casing journaled for rotation within the rotation chamber of said engine housing;
- (c) a rotor assembly journaled for rotation about an axis which is eccentric with respect to the rotational axis of said rotor chamber casing, said rotor assembly including,
- I. a rotor body positioned within the rotor chamber of said rotor chamber casing,
- II. at least a spaced pair of radially reciprocal vanes mounted in said rotor body to form a combustion chamber therebetween,
- III. an output shaft fast with said rotor body for rotation therewith and extending axially from said rotor body, said output shaft having an elongated power output end;
- and
- (d) means connected between said rotor assembly and said rotor chamber casing for coupling combustion induced rotary motion of said rotor assembly to said rotor chamber casing so that said rotor chamber casing is driven at the same speed as said rotor assembly.
