Title:
ROTARY COMPRESSOR
Document Type and Number:
Japanese Patent JP2014009612
Kind Code:
A
Abstract:

To solve a problem that since formation of a closed space in a cylinder of a rotary compressor is not always easy, another technique capable of effectively suppressing heat receiving of a suction refrigerant is required.

A rotary compressor 100 comprises: a closed vessel 1; a second cylinder 15; a second piston 28; a lower bearing member 7 (end plate member); a second vane 33; a second suction port 20; a second discharge port 41; a second partition member 10; and an oil holding part 53. The second partition member 10 is attached to the lower bearing member 7 so as to form a refrigerant discharge space 52 to be a flow channel of a refrigerant discharged from a second discharge chamber 26b through the second discharge port 41 on opposite side of a second cylinder chamber 26. A first communication path 7p is formed on the lower bearing member 7 so as to bring a part of oil stored in an oil reservoir 22 into the oil holding part 53. The oil holding part 53 is configured so that an upper end 7h is inclined from a horizontal direction and the first communication path 7p is communicated to the upper end 7h.
