First embodiment has following advantage:
(1) it is long more that oil separates chamber 36 (11 the direction from baffler formed parts 33 to cylinder block), and refrigeration agent is long more in the distance that oil separates eddy flow in the chamber 36.Correspondingly, oil separates the oil separation effect raising in the chamber 36.Extend in the cylinder block 11 and baffler formed parts 33 as whole housing constituent element because oil separates chamber 36, oil separates chamber 36, and to separate the length of chambers only in the fixing frame 32 of cylinder block 11 time than oil long.Correspondingly, the oil that has improved oily separation chamber 36 separates effect.
(2) opening 403 is formed in the baffler formed parts 33 as the refrigerant inlet that oil separates chamber 36.The gas of discharging, flows into oil by opening 403 then and separates chamber 36, and around oily splitter cylinder 41 eddy flows, flow downward simultaneously to the upper reaches from cylinder block 11.Therefore, prolong refrigeration agent eddy flow distance, improved oily separation effect.
(3) if oily apotheca is positioned at oil to be separated under the chamber 36, a large amount of separating oil just also can be stored in oil and separate in the chamber 36.The oil that is stored in the oil separation chamber has significantly dwindled the space that is used for the oil separation in the oily separation chamber 36.In this case, will shorten the physical length (11 direction) that oil separates chamber 36, therefore, significantly reduce the oily oil that separates chamber 36 and separate effect from baffler formed parts 33 to cylinder block.
Because oily apotheca 37 is to separate along circumferentially separating the chamber 36 from oil of cylinder block 11, is used for carrying out oily space of separating in the oil separation chamber 36 and just can significantly dwindled because of oil in reserve.
(4) if oily apotheca 37 and baffler chamber 42 are separated by other members except that liner 34, will increase the number of the parts of compressor, also can corresponding increase cost.Because liner 34 is to stop refrigeration agent from the necessary member that the linkage section between cylinder block 11 (fixing frame 32) and the baffler formed parts 33 leaks, the structure that is used for separating the liner 34 of baffler chamber 42 and oily apotheca 37 makes the number of parts reduce.
(5) discharge passage 40 passes liner 34 and separates chamber 36 with oil and be communicated with.The structure of passing in the discharge passage 40 of liner 34 is the favourable structure that stops the refrigeration agent in the discharge passage 40 to leak by the linkage section between cylinder block 11 (fixing frame 32) and the baffler formed parts 33.
(6) the eddy flow distance of refrigeration agent is long more in the oil separation chamber 36, and oil separation effect is good more.Oil splitter cylinder 41 has further strengthened the eddy flow of the refrigeration agent in the oily separation chamber 36, thereby has increased the distance of eddy flow.Oil splitter cylinder 41 is long more, and the eddy flow distance that oil separates the refrigeration agent in the chamber 36 is long more.Owing to the oil separation chamber that described oil separation chamber 36 ratios only are in the cylinder block 11 is long, oil separation chamber 36 more helps providing the oily splitter cylinder 41 than long.
