摘要： The present invention relates to an indoor exercise bicycle capable of implementing an uphill mode and a downhill mode through a simple structure. An indoor exercise bicycle having uphill and downhill mode functions according to an embodiment of the present invention comprises: a brake unit that controls a pressing force applied to the circumferential surface of one side of a wheel, by means of forward movement of a brake mounting connected to a lead screw rotating through a motor; and a gear unit that is meshed with the brake unit of the lead screw while being spaced apart therefrom by a predetermined distance, and controls speed with respect to the rotational force of the wheel according to the rotation of the lead screw, wherein the brake unit may be operated in an uphill mode, and the gear unit may be operated in the downhill mode.

摘要： The present invention relates to a fluid compressor comprising: a driving module comprising a driving motor embedded in a motor case; and a compression module comprising a rotor, which is rotatably driven by a driving motor and which has a plurality of variable blades radially provided along the outer peripheral surface thereof, a rotor housing for encompassing the rotor, and a cover of the rotor, for closing the rotor housing, wherein the compression modules are stacked and airtight to block contact between fluid passing through the compression module and air outside the compression module, so that the fluid flowing into any one compression module sequentially passes through the remaining compression modules. The rotary shafts provided in each center of the rotors are connected a shaft coupler. The present invention simultaneously achieves a high-efficiency compression ratio and reduces noise caused by the excessive velocity of any compression module.
