Application filed August 15, 1918. Serial No. 250,001.
To all whom it may concern:
Be it known that 1, ROBERT ROTHWEILER, a citizen of the United States, residing at Mount Clemens, county of Macomb, State of Michigan, have invented a new and useful Improvement in Rotary Combustion-Engines, of which the following is a specification.
This invention relates to an internal combustion engine of the rotary type which operates on a quasi-turbine principle.
It comprises a novel arrangement of structure .to compress gases, admit them to the combustion chamber and direct them against the blades of the rotor. This structure can be better described after the detail is understood. The'rotor is provided with a blade or bucket construction which is simple yet effective to accomplish the purposes in view.
In the drawings,
Figure-1 is a side elevation partly in section.
Fig. 2 is a cross section taken on the two section lines 2-2 and 2"- a of Fig. 1.
The construction here shown is intended to be air cooled and hence no water jacket is shown for obviously neither the air cooling or water cooling of the parts is necessary to detail as it is merely an engineering problem. The engine is divided up into a plurality of units which may be of any desired number. Each unit comprises a casting a which is the stator and which is made up of two halves bolted together. Each of the ends of the cylinder is bossed to provide a socket for the ball bearings c that support the rotor shaft 03. The abutting ends of the rotor shafts d have a socket and a projection interlock 7 to bring them into driving relation while a loose alining pin 6 may be fitted into bores in the ends of the shafts. The sides of each stator casting are provided with lugs g which may be bolted to the channel frame bar it. Hence when each stator is mounted upon the frame the abutting ends of the rotor shafts are interlocked without any other means to keep the two shafts together and fix the stator casting to the frame.
The rotor z is eccentrically set in the stator and provided with near-cylindrical sockets y in which the cylindrical bases of the buckets or blades turn. The blades are kept normally projected by the action of the plungers m, the springs 12. and the abutment screws 0 that fit in the bores p and 9 through the rotor and into the cylindrical base of the blades.
The top of the stator is formed into a packing chamber 1" in which slides the packing member s acted upon by the bowed spring t. This packing member is located at the substantial point of contact between the stator cylinder and the rotor cylinder and with the blades divides the space between the rotor and the stator into a plurality of chambers.
u is an intake pipe from the carburter (not shown). It connects with the rotary compressor c which has a rotor and blades built on the same principle as the rotor of the engine. w is the by-pass pipe around the compressor with a cut ofl valve m. Hence the gases may or may not be compressed, as desired. y is a manifold leading to the intakes of the valve housings a and which houses the rotary cylindrical valve 1 provided with the single diametric passage-way 2. This valve housing has two sets of opposed ports. The port opposite the intake port connects with the pipe or elbow 3 that leads to the combustion chamber 4. The combustion chamber is made up of a pair of hemi-spherical castings bolted together. The other set of opposed ports of the valve housing 2 is set at substantially 90 degrees from the first mentioned set and leads respectively into the combustion chamber to which the valve housing is bolted through a suitable flange and into the short pipe-like casting 5 provided with suitable flanges at each end bolted to the valve housing 2 and the stator. This pipe 5 may well be termed the nozzle as it is flared at its mouth to allow the velocity of the gases to increase.
Suitable packing strips 6. are projected against the ends of the stator cylinder from the rotor parts by the springs 7 so as to prevent leakage of the gases between the rotor and the stator walls.
The operation of the engine is as follows: The fuel mixture is taken fromthe carbureter through the pipe in and then into the manifold 3 either through the compressor or the by-pass pipe 10 depending upon whether a compressed charge is desired or not. The
rotary valve 1 is timed so that when the charge is being taken in the passage-way 2 registers with neither sets of ports, and consequently when the by-pass pipe is closed the rotor compresses the gases in the manifold and this compression continues until the valve 1 turns to connect the manifold port and the port leading into the combustion chamber, whereupon the gases escape into the combustion chamber. Upon further turning of the rotary valve the sets of ports are again closed and the charge is fired by sending a current through the spark plug. The valve 1 continues in its rotation and opens up communication between the outgoing portend the combustion chamber and the nozzle 5, allowing the fired gases to escape and expand in the nozzle 5 and expand in the chamber behind the lowermost blade in Fig. 2. This, of course, serves to drive the rotor by virtue of the impulse against the rotor andalso expansion of the gases. The burned gases discharge through the exhaust 8 leading to the exhaust manifold 9.
From the above description it will be understood that any number of units may be set along the frame and connected by simply fitting the ends of the rotor shaft into alinement and into driving connection. A single shaft, in convenient driving relation to the rotor shaft, drives the simple rotary valves that operate to-close the compression chamher to admit the gases to the combustion till chamber and allow the discharge or the enploded gases into the stator.
