Patent ID: 11784525

Abstract:
A rotor that gives rotational power to a compressor part that compresses refrigerant has a rotor core in which through-holes through which the refrigerant passes are formed, the through-holes having a cross section with a plurality of forks in a direction away from a rotation axis, a first end plate that covers a first end surface where one end of both end portions of the through-holes of the rotor core closer to the compressor part is formed, and an upper rotor end plate that covers a lower rotor end surface where the other end of the plurality of holes of the rotor core is formed. The first end plate has a first opening portion that causes the through-holes to communicate with an internal space. The upper rotor end plate has an upper opening portion that causes the through-holes to communicate with the internal space. The upper rotor end plate has projection portions that cover tip end portions, which are divided to respective forks, of the through-holes.
