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.

Abstract: A hermetic compressor assembly having a housing having disposed therein an electric motor including a stator and a rotor drivingly attached to a crankshaft having an eccentric portion, and a compression mechanism operatively coupled to the crankshaft eccentric portion. A counterweight is attached to the crankshaft and is made of progressively stamped metal stock material having selectively varying widths between first and second side edges thereof. The counterweight has one of a plurality of weights, each individual weight directly corresponding to a different stock material width. Also, a method for manufacturing compressors having installed therein counterweights of different weights and having substantially identical axial projection profiles, wherein the counterweights are made by a method which includes providing a progressive stamping die, and planar metal stock material having one of a plurality of different widths between first and second opposite side edges.
