In a preferred construction, the first and second trochanter housing members have substantially the same or identical construction.

One of the main features of the invention is that the trochoidal cavity housing member is provided with an exhaust duct formed by a wall device extending perpendicularly to the side of the housing member.

Another feature of the invention is that the superimposed or sandwiched members are arranged in a superimposed or sandwiched manner so that the superposed members are in a substantially parallel relationship to the axis of the crankshaft and each of the trochanter chambers is An object of the present invention is to provide a double trochanter rotary internal combustion engine having an exhaust duct or passageway communicating with the engine.

Another major feature of the invention is the provision of a Rochley internal combustion engine of the type described above which uses a trochanter housing member of substantially similar construction.

Another main feature of the present invention is to provide a rotary internal combustion engine in which the stacked parts can be easily manufactured by die-casting.

Another feature of the present invention is to provide a dual trochanter internal combustion engine that does not use a common exhaust manifold connected to each of the trochanter housing members.

Other features and advantages of the invention will be understood from the description with reference to the accompanying drawings.

first and second or lower and upper housing members 15;
17 are the first and second trochanteric spaces 19.21 and the first
and second exhaust passages 27 and 29, respectively.
3 and other wall devices bounding each other.

Since the housing parts 15.17 are preferably made by die-casting, they also have lower and upper holes which are arranged in the exhaust duct 31.33 and closed by a respective cover 39.41, in order to facilitate their casting. 35.37.

The housing assembly 13 is further positioned between first and second or lower and upper housing members 15, 17 and includes first and second trochanter cavities 19, 21 and first and second cooling jackets 23, 25 forming further parts and the first and second, lower and upper housing members 1
Exhaust passages 5 that are arranged in the first and second, lower and upper exhaust passages 27 and 29 provided in 5 and 17 and communicated between them.
3. The intermediate member 51 includes an intermediate member 51 which includes a 3.

The housing assembly 13 is also spaced apart from the intermediate member 51 and positioned adjacent the upper or second housing member 17 to further define the upper or second trochanter cavity 21 and the upper or second cooling jacket 25 . It includes an upper wall member 61 which forms a portion and closes the upper end of the exhaust passage 29 provided in the upper or second housing member 17 .

The housing assembly 13 is also spaced apart from the intermediate member 51 and positioned adjacent the lower or first housing member 15 and further between the lower or first trochanter cavity 19 and the lower or first cooling jacket 23. the lower or first housing member 15 forming the other part;
a lower wall member 69 having an exhaust passageway 67 having an outlet 69 adapted to communicate with the exhaust passageway 27 provided in the housing assembly 13 and to be connected in any suitable manner to an exhaust pipe or conduit 71 extending from the housing assembly 13; are doing.

The upper and lower wall members 61,65 also support upper and lower bearings, respectively, which rotatably support a crankshaft 77, which is mounted in the first and second or lower and upper trochanteric cavities 19, 21, respectively. It has first and second or lower and upper eccentric portions that are positioned and rotatably support first and second or lower and upper trochanters 83 and 85, respectively, which rotate to support the first and second trochanters 83 and 85, respectively. 1 and 2
