ABSTRACT:
The invention relates to a small, efficient hermetic compressor for refrigeration wherein reduction in size and minimization of parts is emphasized. The motor compressor unit is mounted within a sealed outer housing and comprises a cast crankcase, which is connected to the stator of the electrical motor by means of only three connecting screws that extend through the stator and are threadedly received in sockets in the downwardly depending legs of the crankcase. The crankshaft is pressed into the motor rotor and is journaled within the crankcase for rotation about a vertical axis. The crankcase includes a slot extending into the cylinder so that the connecting rod can be inserted laterally into the cylinder at the same time that it is slipped over the end of the crankshaft, and the wrist pin is then inserted through the same slot, through the piston and connecting rod, and is held in place by a spring clip.
