Latest Patents

Noda's latest patents include innovative methods for lubricating bearings in machines that handle liquefiable gases. One of his patents describes a method in which a refrigerating machine utilizes a reservoir heated by an electric motor driving a compressor. This reservoir contains oil up to a certain level and is fed with refrigerating liquid complemented with oil. As the liquid vaporizes, oil falls back into the liquid state. A series of lubrication conduits connect the individual bearings of the compressor to the reservoir, allowing refrigerating gas loaded with an oil mist to lubricate the bearings effectively. Another patent outlines a method for lubricating bearings in refrigeration compressors, where refrigerant liquid containing a small amount of dissolved oil is vaporized while cooling the motor. This innovative approach eliminates the need for an oil recirculating pump, as the motor casing acts as a sump for the majority of the oil.
