Title:
CLOSED-TYPE COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/186357
Kind Code:
A1
Abstract:
Provided are a closed-type compressor and a refrigeration cycle device equipped with the same, the closed-type compressor being capable of ensuring a sufficient flow passage area of a discharge flow passage for discharging a gas refrigerant from a partitioning plate discharge space, suppressing a degradation in the stiffness of a partitioning plate, and achieving improvements in compression performance and reliability. The partitioning plate is provided with a partitioning plate space. A compression mechanism part is provided with a merging passage which merges a working fluid in a muffler chamber on a sub bearing side and a working fluid in the partitioning plate space and guides the fluids to a muffler chamber on a main bearing side. The partitioning plate space has a connection flow passage connected to the merging passage. The dimension of the connection flow passage in a direction perpendicular to an axis of a rotary shaft is greater than the dimension of the connection flow passage in the axial direction.
