Abstract
In a general-purpose engine including a cylinder block extending obliquely from one side of a crank case, and a cylinder head connected to an end surface of the cylinder block via a gasket, a unidirectional valve for allowing a flow of a fluid from a crank chamber to a valve operating chamber and blocking a reverse flow of the fluid is installed in an upper oil passage. In a case where lubricant oil reserved in the crank chamber flows into the valve operating chamber via a lower oil passage when the engine inclines such that the inclined cylinder block further slants, positive pressures transmitted from the crank chamber to the valve operating chamber push the oil, which once flows into the valve operating chamber, back to the crank chamber via the lower oil passage.
