Compressor

Abstract

It is an object of the present invention to make an oil-reservoir chamber independent from a motor chamber into which a refrigerant compressed by a compressor mechanism is introduced, thereby reducing a compressor in size. In a compressor 1 , a partition member 7 is provided in a housing 3 on the opposite side from a compressor mechanism 4 with respect to a motor 5 . The partition member 7 is pushed by a stator 5 a of the motor 5 , thereby liquid-tightly fixing the partition member 7 to the housing 3 . The oil-reservoir chamber 6 is formed independently from a motor chamber 2 in which the motor 5 is accommodated, and lubricant oil is efficiently separated from a refrigerant with a simple structure.

1 . A compressor having a housing in which a compressor mechanism and a motor for driving said compressor mechanism are accommodated, wherein 
 an oil-reservoir chamber which is independent from a motor chamber in which said motor is accommodated is formed in said housing on the opposite side from said compressor mechanism with respect to said motor.    
   
   
       2 . The compressor according to  claim 1 , wherein a partition member for liquid-tightly dividing said motor chamber and said oil-reservoir chamber from each other is disposed between said motor chamber and said oil-reservoir chamber, thereby forming said oil-reservoir chamber.  
   
   
       3 . The compressor according to  claim 1 , wherein a partition member for liquid-tightly dividing said motor chamber and said oil-reservoir chamber from each other is disposed, said partition member is pushed by a stator constituting said motor, thereby fixing said partition member to said housing.  
   
   
       4 . A compressor having a housing which accommodates therein a compressor mechanism for sucking, compressing and discharging a refrigerant, a motor for driving said compressor mechanism, an oil-reservoir chamber for storing lubricant oil which lubricates a sliding portion including said compressor mechanism, and an oil passage through which said lubricant oil stored in said oil-reservoir chamber is pumped up, wherein 
 a partition member for separating said oil-reservoir chamber from said compressor mechanism and said motor is provided, said partition member is provided at only its upper portion with a through hole through which the refrigerant is discharged out, said compressor mechanism and said motor are completely separated from each other at a lower portion of said partition member, and said oil passage is provided in a lower portion of said oil-reservoir chamber divided by said partition member.    
   
   
       5 . The compressor according to  claim 4 , wherein the refrigerant discharged from said through hole is allowed to collide against a portion of said housing, thereby separating the lubricant oil from the refrigerant.
