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.
