ABSTRACT:
This device functions as a compressor or pump when driven in rotation, and functions as an engine when driven by expansion energy. A housing encases a vane rotor mounted off center for rotation in a cylinder. The slotted rotor is constructed with vane bearing inserts retaining arcuate cast iron vane bearings adjacent the multiple vanes. Vanes are flexibly secured by vane retainers mounted on a rotatible central shaft surrounded by a bushing functioning as a bearing. Improved sealing means are incorporated encircling the rotor and at the edges of the rotor vanes. The device may be utilized as an internal combustion engine by incorporating fueling and spark means. The machine is particularly suited to be driven by expanding gases such as natural gas, air, fluorocarbon gases, or steam as a motor.
