<p>A sealing device (60) is provided on the outer circumference of an oil pressure unit (1), or on the partitioning wall (21) of a sub-reservoir (20) surrounding the oil pressure unit (1), or therebetween so as to provide a sealing between said partitioning wall (21) and said outer circumference of the oil pressure unit (1) while an engine stops and allow a part of an oil to leak therebetween while the engine drives. Since the oil is perfectly prevented, while the engine stops, from leaking between the outer circumference of the oil pressure unit and the partitioning wall of the sub-reservoir, the oil amount may be enough secured in the reservoirs though not supplied from the cylinder head, and the air cannot be absorbed into the high pressure chamber.</p> |
