Title:
COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/111350
Kind Code:
A1
Abstract:
In order to provide a refrigeration cycle device and a compressor having an accumulator with which pressure loss in an inner pipe can be reduced, a compressor (100) comprises: a compression mechanism unit (3) having at least one cylinder (31); an accumulator (140) for separating a refrigerant into a gas and a liquid; an inner pipe (44) which is in the interior of a container (141) forming the accumulator, one end (45a) of the inner pipe opening inside the container and the other end (45b) connected to an opening provided in the container; and an intake pipe (5) connecting the accumulator and the compression mechanism unit, one end (51a) of the intake pipe connected to the inner pipe positioned in the opening, and the other end (51b) connected to an intake opening (42) of the cylinder. The intake pipe comprises: an accumulator connection section (5a) constituting a pipe connected to the inner pipe; a cylinder connection section (5c) constituting a pipe connected to the intake opening of the cylinder and having a smaller diameter than the accumulator connection section; and a tapered section (5b), which is a pipe one end of which is a larger-diameter end formed so as to be continuous with the accumulator connection section and the other end of which is a smaller-diameter end formed so as to be continuous with the cylinder connection section, wherein the diameter decreases continuously from the one end to the other end.
