TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rotating device for an internal combustion engine and a pump and a compressor.
[0002]
[Prior art]
A conventional general rotating device is a reciprocating type or a Wankel type rotary type.
[0003]
[Problems to be solved by the invention]
However, according to the above prior art, the vibration is large, and as a countermeasure against this, a balance weight is provided or a continuous type is used to cancel the vibration, so that the weight becomes heavy and the appearance becomes large.
Also, one cycle stroke is the limit for one rotation of the shaft.
Accordingly, it is an object of the present invention to provide a lightweight and compact device with less vibration.
[0004]
[Means for Solving the Problems]
In order to solve the above problem, the invention of claim 1 enables a plurality of rotors to be arranged, thereby allowing the rotor itself to also serve as a balance weight and a plurality of cycles per one rotation of the shaft. This is a device that realizes smooth rotation by performing a stroke.
The invention according to claim 2 is such that each rotor is rotated about an axis while maintaining a constant interval.
A third aspect of the present invention is to improve the sealing performance in the device of the present invention.
According to a fourth aspect of the present invention, in the device of the present invention, the inner wall of the housing and the rotor are brought into close contact with each other.
Further, the invention of claim 5 promotes smooth rotation in the device of the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of the present invention is shown in FIG.
A plurality of rotors 3 are fitted between the inner wall of the housing 1 and the guide portion 2, and connected by link plates 4 and link pins 5. The ignition plug 6, the intake port 7, and the exhaust port 8 are arranged at appropriate positions. The housing 1 has a lid, and is fixed with mounting bolts 9 and positioning pins 10.
This is an internal combustion engine in which the rotor is rotated in this state to extract power from the central shaft 11.
[0006]
【The invention's effect】
According to the present invention, it is possible to produce a device that is small, lightweight, and excellent in quietness.
