Title:

Document Type and Number:
WIPO Patent Application WO/2018/189827
Kind Code:
A1
Abstract:
This enclosed compressor is provided with a cylindrical cylinder forming a compression chamber that compresses refrigerant through the rotation of a crankshaft, and a bearing that is disposed in an axial-direction end surface of the cylinder and rotatably supports the crankshaft. Formed in the bearing are a discharge port that discharges refrigerant compressed in the compression chamber, and a recessed counterbore hole that is provided to the periphery of the discharge port and that has the capacity needed for the refrigerant discharged from the discharge port to flow. The discharge port is provided so as to be eccentric relative to the counterbore hole toward the bearing center, and a discharge cutout through which the compression chamber and the discharge port communicate is provided to an inner-wall portion of the cylinder, which faces the eccentric discharge port.
