ABSTRACT:
A rotary piston engine including a lubricating system having an oil passage extending axially through an eccentric shaft for supplying lubricating oil from an oil pump to bearing portions. A pressure regulator valve is provided in said oil passage in the eccentric shaft so that the oil pressure as regulated by the regulator valve is not affected by the centrifugal force which may be produced in the oil passing through a radial passage between the oil pump and the oil passage in the eccentric shaft. The regulator valve may include a temperature sensor which is responsive to the surrounding temperature.
