Abstract
The invention relates to an electric motor and piston type compressor unit used for small refrigerators. The housing or cylinder of the compressor is attached to the motor casing and these two members, as a unit, are resiliently mounted in a sealed housing. In order to minimize the overall size of the unit, and specifically the outer housing, the piston connecting rod has a special shape at its crank end to facilitate the initial installation of the piston and connecting rod. The crank end of the connecting rod has a larger bore than the crankpin and the shape of the crank end is characterized by a recess which allows the crank end to clear the crankpin while being moved into surrounding relation to the crankpin after which a sleeve is installed between the crank end and the crankpin. The recess is strategically located so that while it facilitates the assembly operation there is no compromise or sacrifice with regard to the maximum loads the connecting rod can withstand.
