Bypass Valve When Running


As soon as the oil pressure has built up, some of the oil flows through the counter-pressure line to the cavity under the valve plunger equally counteracting the pressure exerted by the oil from above, permitting the mechanical spring to expand and, thus, push the valve plunger up and close the oil gallery of the direct lubricating circuit. This forces the oil to flow through the oil cooler before it can reach the lubrication points within the engine.
