Valves used lubrication system, in order to meet requirements of various engine oil pressure

摘要

A lubricating system for an internal combustion engine has valves, in order to optimize by a motor oil flow rate and thus to increase a degree of effectiveness. The lubrication system comprises a by means of the motor operated oil pump, which is connected in such a way, in order to oil under pressure by means of a main oil supply to a main bearing by means of gear, a cam by means of gear, a cam phases plate as well as to provide the switching valve tappet. A pair of pressure valves, which increases with a main bearing by means of gear and the cams are connected by gear, an oil flow rate selectively to the cam by means of gear and the main bearing by means of gear, in order to obtain a on the cam phases plate oil pressure supplied to raise. A pressure regulator valve is connected with the cam by means of gear, in order to control an oil pressure on the switching tappets of cylinder shut-off or for a stepped valve operation is delivered. The optimization of the flow of oil, that the motor can use a smaller oil pump and thus has a larger engine efficiency, while for an actuation of the cam phases plate or the switching plunger is ensured over the entire engine speed range.
