Horizontal closed type compressor for vehicle use and cooling system of electric compressor for vehicle use

Abstract

An object of the invention is to provide a horizontal closed type compressor for vehicle use which can suck a lubricating oil from an oil suction pipe without an oil surface of the lubricating oil becoming lower than the oil suction pipe, even in the case that a vehicle is inclined and the compressor is accordingly inclined. The horizontal closed type compressor for vehicle use is provided with a motor element provided within a closed container so as to direct a rotary shaft in a lateral direction, a compression element driven by the motor element, a lubricating oil received in the closed container, and an oil supplying means for feeding the lubricating oil to the compression element, the oil supplying means being provided in an opposite side to the motor element of the compression element, the compression element compresses the refrigerant gas sucked from an external portion of the closed container so as to discharge to the side of the motor element within the closed container, and thereafter discharges out of the closed container from the side of the oil supplying means, and partition walls sectioning an interior portion of the closed container while allowing the refrigerant gas and the lubricating oil to move are respectively provided in the side of the motor element and the side of the oil supplying means in the compression element.

What is claimed is:  
     
         1 . A horizontal closed type compressor for vehicle use comprising: 
 a motor element provided within a closed container so as to direct a rotary shaft in a lateral direction;    a compression element driven by said motor element;    a lubricating oil received in said closed container; and    an oil supplying means for feeding said lubricating oil to said compression element, said oil supplying means being provided in an opposite side to said motor element of said compression element,    wherein said compression element compresses the refrigerant gas sucked from an external portion of said closed container so as to discharge to the side of the motor element within said closed container, and thereafter discharges out of said closed container from the side of said oil supplying means, and    partition walls sectioning an interior portion of said closed container while allowing said refrigerant gas and the lubricating oil to move are respectively provided in the side of said motor element and the side of the oil supplying means in said compression element.    
     
     
         2 . A horizontal closed type compressor for vehicle use as claimed in  claim 1 , wherein an external pipe for discharging the refrigerant gas discharged from said compression element to the side of said motor element within said closed container via an external portion of said closed container is provided in said closed container.  
     
     
         3 . A horizontal closed type compressor for vehicle use as claimed in  claim 1  or  2 , wherein said compression element is constituted by a plurality of rotary compression elements provided between both of said partition walls.  
     
     
         4 . A cooling system of an electric compressor for vehicle use comprising: 
 an electric compressor having a motor element provided within a closed container and a compression element driven by said motor element, and compressing a refrigerant gas sucked from an exterior portion of said closed container by said compression element and thereafter discharging to the external portion of said closed container; and    a heat exchanging means arranged so as to establish a heat exchanging relation with an engine cooling system of a vehicle,    wherein the refrigerant gas discharged from said compression element is flowed to said heat exchanging means, is returned to the side of said motor element within said closed container and thereafter is discharged to the external portion of said closed container.    
     
     
         5 . A cooling system of an electric compressor for vehicle use as claimed in  claim 4 , wherein said heat exchanging means is arranged so as to establish a heat exchanging relation with a radiator of said vehicle.
