<p>PURPOSE: A compressor having a balance weight is provided, for reducing a leakage of oil in a freezer from a vent pipe as repressing a loss of a pressure. CONSTITUTION: In a motor compressor, a vent pipe(10) is installed between a compressor(2) and a motor(12), and an opening of the vent pipe(10) is installed at the center of the rotation of an axis of the compressor as near as possible. A cylindrical ring(9) is established with insulation material at the outer circumference of an end(8) of a coil of the side of the motor of a stator(6). The cylindrical ring(9) covered at the end(8) of the coil is made of the same material as insulation material inserted into the coil of the stator, made of plastic material thin and having an excellent insulation property and a processing property. And a pressure device of a rotator(4) is positioned near the vent pipe(10), the oil in a freezer in vented gas to a freezing cycle is reduced by reducing the spiral rotation in the space near the vent pipe(10) on the upper part of the rotator by making an end face of the compressor to be flat as making the shape of a balance weight(5) to be circle.</p> |
