Abstract: This disclosure describes new horizontal roller-piston/vane type rotary compressors with novel features such as new lubricating oil circuit designs to provide reliable oil lubrication, and increase tiltability during operation. Also new multi-pump configurations of horizontal compressors are introduced in order to significantly increase redundancy, reliability, and turn down ratio. Rotary compressors may be configured with subsets of the disclosed features to configure those compressors for specific applications.

Abstract: Aspects described herein relate generally to rotary compressors that incorporate a flywheel within to significantly reduce the compressor vibration and drive torque ripples as well as to achieve a higher overall electro-mechanical efficiency and potentially lower combined costs of BLDC rotary compressors and their drive electronics.

Abstract: The present disclosure relates to a new breed of high performance compressors and associated vapor compression systems that can be used in wide ranging refrigeration, cooling and heating applications with significantly increased compressor isentropic efficiency, motor efficiency, reliability and longevity of the motor, the compressor pump and the system as a whole, as well as COP, heating capacity, and SEER of the new vapor compression systems utilizing the new high performance compressors. The design philosophy and modifications to the current configuration of rolling piston rotary compressor to arrive at the high-performance version of the same type will be readily applicable to other types of vapor compression compressors with only minor changes opening the way for adoption of the new design philosophy by the entire compressor industry resulting in serious reduction of carbon footprint for air conditioners, heat pumps and refrigerators worldwide.

Abstract: The present disclosure relates to a low noise, compact rotary compressor configured to damp noise and vibration generated from internal components. The compressor may include a stator holder coupled to the stator and the pump, providing physical separation between the stator and the casing. The compressor may also include a pump holder coupled to the pump and the casing, providing physical separation between the pump and the casing. Additional damping components may be placed at various coupling points within and around the stator holder and/or pump holder. The suction line connection may also be configured to reduce noise and vibration. Aspects of the present disclosure may be applicable for reducing the noise and vibration in a number of fluid displacement devices and BLDC motors.

Abstract: Disclosed is a pressurized internal oil management system, comprising an oil dam, at least one oil separator, at least one oil collection manifold, at least one oil pump, and one or more paths for returning the separated oil; said system integrated within the casing of a fluid displacement device to supply adequate lubrication regardless of orientations under zero to full gravity, and methods and applications related thereto. Fluid displacement devices useful herein include oil lubricated rotary or reciprocating machinery, such as compressors, expanders, pumps and engines, in the casing of which exists one or more drive mechanisms that can be utilized to operate the oil management system, in most cases without even increasing the size of the casing.
