Title:
FLUID COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/184873
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a fluid compressor comprising: a driving module (10) comprising a driving motor and a motor case in which the driving motor is embedded; and a compression module (20) comprising a rotor (21), which is rotatably driven by means of the driving motor and which has a plurality of variable blades (22) radially provided along the outer peripheral surface thereof, a rotor housing (23) for encompassing the rotor (21), and a cover (25) of the rotor (21), for closing the rotor housing (23), wherein the compression modules (20) are assembled in a form in which two or more compression modules are stacked, the respective compression modules (20) airtightly come in close contact with each other so as to block contact between fluid passing through the compression module (20) and air outside the compression module (20), so that the fluid flowing into any one compression module (20) sequentially passes through the remaining compression modules (20), all the compression modules (20) are driven by means of one driving motor, and rotary shafts (53) provided in each center of the rotors (21) inside the respective compression modules (20) are connected by means of a shaft coupler (51), and thus the present invention simultaneously achieves a high-efficiency compression ratio and reduces noise caused by the excessive velocity of any one compression module (20).
