Hermetic compressor for a refrigeration system, for vehicular use

Abstract

A hermetic compressor for a refrigeration system, for vehicles. A fixing system for an electric pump motor in a housing of the compressor has a support and fixing tray ( 1 ), the tray is formed with a base in an inverted pyramid with rectangular transversal section and having a height, lateral curvilinear sides with an edge and rounded corners. The tray has an opening in the base which is smaller than an opposed opening of the tray. The largest of the sides face each other and form at the base an opposed pair of flaps ( 2 ) turned inward. Each flap has a pair of spaced apart holes ( 3 ), dimensioned in correspondence to holes ( 4 ) of a stator ( 5 ) of the motor and each is fixed by screws ( 7 ). A free border of the tray ( 1 ) forms a circling side flap ( 6 ) that is turned outward so that it may be interposed between edges of bottom ( 8 ) and upper ( 9 ) parts of the housing. An opening extends from the smaller opening almost the entire area of each of the smaller of the side walls of the tray.

1 . Improvement in hermetic compressor for refrigeration system, with vehicular application, wherein it comprises essentially, a fixing system of the pump/electric motor assembly to the compressor housing, and comprising a support and fixing, as a tray ( 1 ) substantially inverted trunk-pyramidal, of rectangular transversal section, with expressive height, as well as having side lateral slightly curvilinear and rounded edges and corners, this tray totally open in its smaller base or bottom, to which level the biggest side faces make an opposite pair of flaps ( 2 ) turned inside, as well as provided, each one, of an extreme pair of holes ( 3 ), dimensioned in exact correspondence to the holes ( 4 ) of the stator ( 5 ) of the compressor electric motor, to which are fixed by the screws ( 7 ) of the same, while the opposed and free border of the same tray ( 1 ) makes a circling side flap ( 6 ), turned outside, and interposed and imprisoning between the corresponding edges of the parts, respectively bottom ( 8 ) and upper ( 9 ), composing the compressor housing, such tray ( 1 ) presenting further a bottom integral opening extended by almost the entire area of its smaller side walls.  
     
     
         2 . A hermetic compressor for a refrigeration system, for vehicles, comprising: 
 a fixing system for an electric pump motor in a housing of the compressor and comprising a support and fixing tray ( 1 ), the tray being formed with a base in an inverted pyramid and rectangular transversal section and having a height, lateral curvilinear side walls with an edge and rounded corners, the tray having an opening in the base which is smaller than an opposed opening of the tray, the largest of the side walls facing each other and forming at the base an opposed pair of flaps ( 2 ) turned inward, each flap having a pair of spaced apart holes ( 3 ), dimensioned in correspondence to holes ( 4 ) of a stator ( 5 ) of the motor and each being fixed by screws ( 7 ), a free border of the tray ( 1 ) forming a circling side flap ( 6 ) that is turned outward so that it may be interposed between edges of bottom ( 8 ) and upper ( 9 ) parts of the housing, and an opening extending from the smaller opening almost the entire area of each of the smaller of the side walls.
