Abstract

IMPROVEMENTS IN THE REFRIGERATING APPARATUS, characterized in that the compressor mechanism essentially comprises the assembly constituted by an upper hollow envelope of a plate, inside of which is mounted the stator of an electric motor supported on a support piece that is elastically linked , with respect to the internal bottom of the lower hollow envelope, of the plate, of the apparatus, so that said support part carries, in its central part, the housing for the axis of the electric motor whose upper end is the rotor carrier of said electric motor, with the particularity that said shaft is helically grooved to ensure its lubrication and the lower end of said shaft is a carrier of the mobile central member, of an eccentric rotary pump and underneath this central member there is a cylinder head on which, on the one hand , there is a chamber and suction duct with a valve interposed therein and this duct empties into the suction zone of the pump and another part there is another compression line that opens into the compression zone of the pump with the interposition of a compression valve, so that both lines go out of the device to be coupled to the external circuit The corresponding cooler and the aforementioned assembly of the aforementioned organs is installed inside said two opposite enclosures and welded together to ensure its airtight closing and in the upper part of the apparatus there is a plug carrying the external connecting pins the conductors that go to the electric motor while the bottom of the lower enclosure, able to contain oil, is in communication, through a central hole, with the lower end of the axis of the electric motor.
