Abstract

PURPOSE: To improve the compression efficiency and obtain a high compression ratio by laminating multiple rotor elements with nearly the same shape, with their phases staggered in sequence, to constitute a two-shaft multi-blade fluid machine.
CONSTITUTION: When eight rotor elements 42, 62 with four Roots tooth form sections 41, 61 respectively are laminated, with their phases staggered in sequence in the opposite directions to each other, in a pair of rotors 40, 60, spiral operating spaces S are formed on the outer periphery portions of the rotors 40, 60. When a drive shaft 15 is driven, the rotors 40, 60 are rotated in the arrow A, B directions respectively while being engaged with each other, and their outer periphery surfaces face the wall surface of a rotor chamber 14 at a minor clearance. The operating spaces S are practically hermetically cut off from each other, and the air sucked into the operating spaces S through an intake hole 76 is compressed and discharged through a discharge port 78. The operating spaces S act nearly similarly to a screw compressor, thus a high compression ratio can be achieved.
