ABSTRACT:
In a refrigeration motor compressor of the hermetic type containing an electric motor compartment, and a crankcase compartment, an oil separator installed in the crankcase arranged to prevent oil splash from entering the system. The oil separator includes a generally nautilus shell-shaped structure, an elongated tubular structure, and a check valve assembly for controlling flow. The shell-shaped structure has cross baffles for controlling flow characteristics and a pin for centering the check valve assembly. The check valve assembly includes a helical spring with one end positioned in a retainer in the tubular structure. The other end of the spring fits around the pin and abuts an orifice disk in the shell-shaped structure.
