ROTARY COMPRESSOR

PROBLEM TO BE SOLVED: To reduce the rate of oil delivered from a main bearing upper end part outward an sealed case by making compressed gas delivered from an emission hole flow to a winding of a motor stator, and leading atomized oil to the motor stator. SOLUTION: Compressed gas is delivered from an emission hole 16, passes a stator winding part 2a, and collides with a stator end part 2b. After that, compressed gas passes a clearance 1a between a stator 2 and a rotor 3, or a clearance 3a between the stator 2 and the rotor 3, and is delivered outside a case bypassing a pipe arranged on a sealed case. Atomized oil is mixed with compressed gas, its oil flows in the same direction as compressed gas. When a part of atomized oil collides with a stator winding, it is stuck on the stator winding, as a result, oil drops are generated, and drop down from the stator winding part 2a. When remaining atomized oil collides with the stator lower end 2b, its oil is stuck on the stator lower end 2b, as a result, oil drops are generated, and drop down from the stator lower end 2b. It is thus possible to ensure atomized oil in the sealed case.
