PURPOSE:To control the oil pressure of an oil feeding to each lubrication part optimum at all times and to prevent an oil leakage, etc., by releasing a high pressure oil escape hole according to the movement of a relief valve at the time when the viscosity of an oil is increased and the oil pressure becomes more than the set value. CONSTITUTION:A relief valve 2 is energized to an oil inlet port I side by a regulator spring 3 prior to the running of an engine, closing an oil escape hole 4. On the other hand, the relief valve 2 is moved to the bottom face B of the cylinder of a regulator body 1, i.e., in the direction of a 1st retainer 8 at the time when the oil viscosity is high at the engine low temp. running time, etc. A stopper 11 is then penetrated through the high pressure oil escape hole 6 of the relief valve 2 and abutted to a check valve 5. The high pressure oil escape hole 6 is thus released with a high pressure releasing spring 7 being compressed and the high pressure oil of a piston chamber 20 inside is flowed into a spring chamber 30. |
