Title:
HERMETIC TYPE COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2018053874
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high efficiency hermetic type compressor and a refrigeration cycle device in which refrigeration oil is positively supplied to a division plate and a blade abutment part to reduce leakage of refrigerant between an inside part of a cylinder and an external part.SOLUTION: A hermetic type compressor in accordance with a preferred embodiment of this invention is constituted in such a way that a motor part and a compressor mechanism part are installed in a hermetic case storing refrigeration oil at its bottom part and the compressor mechanism part is driven by the motor part through a rotating shaft having a plurality of eccentric parts. The hermetic type compressor is constituted to comprise the compressor mechanism part that includes a plurality of cylinders, partition plates formed by two partition plate members divided by two divided abutment surfaces in parallel with an axial direction of the rotating shaft to divide the plurality of cylinders, rollers fitted to a plurality of eccentric parts and rotated in an eccentric manner, blades abutted against the outer peripheral surfaces of the rollers and reciprocated. Each of the divided partition plate members is arranged while a position of one divided abutment surface is aligned with a sliding part of the blade and a groove opened at each of the cylinder abutment surface side is arranged between the divided abutment surfaces.SELECTED DRAWING: Figure 5
