Abstract
A compressor includes a crankshaft, an electric motor, a counterweight, and an oil outflow reduction member. The electric motor has a rotor coupled to the crankshaft and a stator in which the rotor is housed with an air gap formed between the stator and the rotor. The counterweight is disposed adjacent to the rotor and is integrated with the crankshaft. The oil outflow reduction member encloses an upper side, a lower side, and a lateral side of a counterweight passing space. The counterweight passing space is a space through which at least part of the counterweight passes when the crankshaft rotates 360°.

A compressor comprising:
- a crankshaft;
- an electric motor having a rotor coupled to the crankshaft and a stator in which the rotor is housed with an air gap formed therebetween;
- a counterweight being disposed adjacent to the rotor and being integrated with the crankshaft;
- and
- an oil outflow reduction member enclosing an upper side, a lower side, and a lateral side of a counterweight passing space through which at least part of the counterweight passes when the crankshaft rotates 360°, the oil outflow reduction member preventing inflow of oil into the counterweight passing space,
