Abstract

PURPOSE:To simplify the structure, make it compact, save energy, and improve efficiency by rotating multiple rotors, main and driven, fitted on the same shaft quickly or slowly via the respective variable-speed sprocket having a pair of eccentric shafts. CONSTITUTION:Main and driven rotors 1, 2 are inclined against an axis; if the angle is made small the compression ratio, i.e., sprocket variation, becomes large; and if the angle is made small the compression ratio becomes small. Power shaft sprockets 15, 16 are rotated at a fixed speed, and while they are rotated one rotation, intermediate shaft sprockets 11, 13 are rotated one rotation, slow-quick, thus when the power shaft is rotated two rotations, the rotors are rotated one rotation at a variable speed, slow-quick-slow-quick. Only sprockets 15, 16 for the main and driven rotors of the power shaft are fixed at a position rotated by 180 deg., the others are all made free, and the intermediate gear ratio is made 2:1. Next, the volume of individual chambers between the rotors is changed by the variable-speed rotation of the rotors, 8 times of compression and suction are repeated during one rotation of the rotors, thereby the structure can be made compact, energy is saved, and the efficiency can be improved.

の需要が急増している。[Detailed Description of the Invention] In recent years, demand for compressed air has rapidly increased as automation, robotization, and energy conservation have progressed in industries, space technology, medicine, transportation, and the like.

現在産業界全般で最も多く使用される レシプロ型圧縮機は振動、騒音、構造の複雑、効率の低

考案した。Reciprocating compressors, which are currently the most commonly used in industry, have drawbacks such as vibration, noise, complex structure, and low efficiency. Therefore, we devised an energy-saving and highly efficient rotary compressor.

回転圧縮機又は原動機は先達により 種々考えられ、レシプロ型より有利であろうと思われる

The main rotor and the slave rotor are coaxially assembled at the center of the casing 3. The main rotor and the slave rotor rotate slowly and rapidly in the casing in a free state. A main rotor gear 10 and a main rotor speed change sprocket are attached to the intermediate shaft 9. A slave rotor gear 12 and a slave rotor speed change sprocket 13 are attached on the same axis.

各ローターは軸心に対し角度を持つ。この角度を小さく

度を大きく取れば、圧縮比は小さくなる。Each rotor has an angle with respect to its axis. If this angle is made small, the compression ratio (sprocket center ratio) will be increased, and if this angle is made large, the compression ratio will be decreased.

It is fixed in the rotated position and free with each other, and the intermediate gear ratio is 2:1.
