Latest Patents
One of his latest patents is a compressor discharge valve providing freeze and charge migration protection. This innovative refrigerant system includes a compressor with a discharge valve that temporarily restricts the compressor's outflow at startup. This design allows the discharge pressure to quickly rise, forcing lubricant back to the compressor. Additionally, the discharge valve prevents the axial face of a rotor of a screw compressor from rubbing against the bearing housing axial face of the compressor's housing. Under certain low ambient air temperature conditions, the valve closes to help prevent the system's evaporator from freezing up. The discharge valve features a novel arrangement of a piston, a valve stem extending from the piston, and a valve plug pivotally attached to the valve stem. This pivotal connection ensures a positive seal between the valve plug and a valve seat, while a somewhat restricted fluid passageway helps prevent the valve from chattering as it opens.
Another significant patent is the oil flow protection scheme, which is a protection system for a compressor. This system comprises a compressor with at least one rotor and bearing, along with a lubrication system that includes an oil recovery device. The oil protection system features a compressor discharge temperature sensor, a differential pressure sensor in the bearing conduit, and an oil detector in the rotor conduit. These components work together to ensure the proper functioning and longevity of the compressor.
