ABSTRACT:
A lubrication system for a rotary-piston internal combustion engine of the trochoid type with roller or needle bearings between the eccentric and the rotor. Lubricating oil in a dosed quantity is passed through a bore in the side part adjacent the gearing between the shaft and the pinion of the gear, from where it is supplied to the connection of the eccentric where, due to the centrifugal force, it is sprayed or splashed into a collector plate at the eccentric wall at the side of the gear. A bore leads from this collector plate to the eccentric bearing and passes the oil into the bearing under the influence of the centrifugal force. Excess oil serves to lubricate the gear and the gas seal elements.
