The lubricant metering system for a rotary internal combustion engine has a lubricant metering device connected to the engine to communicate with the working chambers of the engine during the compression phase of operation thereof and is in communication with a source of lubricant to receive lubricant to be metered from the latter in a lubricant reservoir. The lubricant metering device is also connected to deliver metered lubricant from the lubricant reservoir to a place of use in the engine. A differential pressure sensing means is provided in the lubricant metering device to sense the differential gaseous fluid pressure in the working chamber and the lubricant pressure in the lubricant reservoir and to displace lubricant from the lubricant reservoir in response to engine speed and load demand.

Lubricant metering system for rotary internal combustion engine

The rotary compressor or expansion engine of the hypotrochoidal, two-lobe housing cavity type in which a rotor of a triangular profile is supported for planetative rotation within the housing cavity, has the meshing relationship of the timing gears angularly indexed slightly with respect to each other and from the theoretically desired position (where the apex portions of the rotor traces a path parallel to the inner surface of the housing cavity) so that the apex portions trace a path such that the apex portions are in close running-fit with the inner surface of the housing cavity in the area of highest pressure differential across the apex portions of the rotor.
