ABSTRACT:
A relief valve, anchored to a rotor plate, is centered in a concave housing area in a front journal bearing of an engine. Insetting the relief valve into the front of the engine correspondingly reduces the overall length of the engine. A semi-cylindrical auxiliary housing area is contiguous with the concave housing area. The auxiliary housing area and the concave housing area are spaced from the relief valve to provide a relief passageway for oil flow. The auxiliary housing area overhangs at least a portion of the relief valve. A relief hole in the relief valve leads to the relief passageway. Splashing of excess oil which is relieved from the relief valve is prevented, and smooth recovery of oil is enabled. Aeration is also lowered.
