Constructed of a steel shell sufficiently large to retard gas velocity and partially remove the sensible heat of compression, The oil ladened gas discharged from the compressor passes through an oil scrubbing labyrinth of spirally wound and shredded metal. Every atom of gas and oil must impinge on-an oily metal surface before it can leave the oil separator. The oil collects in the bottom of the shell and the oil free gas passes directly into the condenser. When the oil lsvel is sufficiently high to lift the float mechanism, the oil flows through the needle valve and directly back to the compressor crankcase.

Oil returning from the system into this accumulator is delivered into the crankcase in predetermined limited amounts by means of capillary tube, These two features afford excellent protection against liquid and oil slugging, which causes damage to the discharge valves of a compressor. The high pressure liquid, when passing through this Heat Exchanger, is cooled several degrees and, therefore, this device adds considerably to the overall efficiency of an installation. This device is particularly adaptable to low temperature work, ice cream, frosted food, ete., and flooded systems operating intermittently, and can be used with any refrigerant except ammonia. Cat.
