ABSTRACT:
An improved means for lubricating the compression seals of rotary engines. The system is provided in a typical rotary engine having a housing with a main shaft extending through the housing and a rotor within the housing and journalled on the main shaft. The rotor includes a bore receiving the shaft. Conventional means are provided for supplying lubricant to the interface of the main shaft and the rotor at the bore. The rotor carries at least one compression seal and is provided with a lubrication conduit for the seal extending from the bore to a surface of the rotor adjacent the seal. During operation of the engine, relative rotation between the rotor and the shaft takes place and generates a pumping action at the interface to drive small amounts of lubricant through the lubrication conduit to the rotor surface to lubricate the seal.
