PURPOSE:To prevent worsening of acceleration performance due to resistance of viscosity of oil, by lifting the opening part of a movable pipe from a surface level of oil in an oil reservoir and eliminating the supply of oil in a low speed range with no necessity of jet lubrication. CONSTITUTION:The pressure from a compressor is introduced to a pressure chamber 10 through an introducing 11. In the high speed range of a turbosupercharger, the pressure in the pressure chamber 10, acting on a plunger member 12, depresses the member 12 till it is adapted to a stopper 10A against tension of a spring 13, and a pump, submerging both a suction port 14A and an attraction port 14B of a movable suction pipe 12A under a level of oil, injects oil from an oil jet nozzle. In the low speed range, the tension of the spring 13, overcoming the pressure supplied to the pressure chamber 10, lifts the movable suction pipe 12A to the uppermost part, and the pump, being only raced, injects no oil from the jet nozzle. |
