Compressor

Abstract

To reduce or prevent failures due to contamination, such as control and/or lubrication failure, the compressor according to the present invention includes an oil separator 230 having a separation portion configured to separate lubricating oil OIL from a working fluid by using a centrifugal force, and a storage portion located below the separation portion and configured to store lubricating oil OIL separated by the separation portion. A hat-shaped trap member 260 is disposed between the separation portion and the storage portion. The trap member 260 allows precipitation and trapping of the contamination CON mixed in the lubricating oil OIL by temporarily storing the lubricating oil OIL separated by the separation portion and discharging a supernatant of the lubricating oil OIL into the storage portion.

1 . A compressor comprising
 an oil separator having:
 a separation portion configured to separate lubricating oil from a working fluid by using a centrifugal force; and 
 a storage portion located below the separation portion and configured to store lubricating oil separated by the separation portion, 
 wherein a trap member configured to temporarily store the lubricating oil separated by the separation portion and to discharge a supernatant of the lubricating oil into the storage portion is disposed between the separation portion and the storage portion. 
   
     
     
         2 . The compressor according to  claim 1 ,
 wherein the trap member has a portion rising toward the separation portion, the rising portion having at least one small hole for allowing the supernatant of the lubricating oil to pass therethrough.   
     
     
         3 . The compressor according to  claim 2 , wherein the trap member is formed of a hat-shaped partition wall. 
     
     
         4 . The compressor according to  claim 3 , wherein the trap member has a communication hole which communicates the separation portion with the storage portion at a center portion of the trap member. 
     
     
         5 . The compressor according to  claim 3 , wherein a flange portion having an annular shape extending radially outward from an upper portion of the trap member is formed integrally to the upper portion of the trap member.
