Abstract

An oil sealing deflector for a turbocharger includes a substantially circular stepped plate which has a central plate portion having a center hole in which a rotor shaft of the turbocharger can be freely inserted, a peripheral plate portion, and an intermediate recessed plate portion provided between the central plate portion and the peripheral plate portion to define an oil reservoir. The peripheral plate portion has an opening for discharging the oil in the oil reservoir. The deflector further includes a tongue which extends from the plane of the recessed plate portion through the opening of the peripheral plate portion.

Claims

1. An oil sealing deflector for use in a turbocharger;

said turbocharger comprising;

a turbine wheel;

a compressor wheel connected to said turbine wheel by means of a rotor shaft;

bearing means adjacent said compressor wheel for rotatably supporting said rotor shaft; and

seal means provided around said rotor shaft between said bearing means and said compressor wheel;

said oil sealing deflector comprising;

a substantially circular stepped plate and a tongue;

wherein said substantially circular stepped plate comprises a central plate portion having a center hole, a peripheral plate portion, a circumferential opening provided in said peripheral plate portion, and an intermediate recessed plate portion provided between said central plate portion and said peripheral plate portion to define an oil reservoir, said intermediate recessed plate portion lying on a plane, and

wherein said tongue comprises an oblique plate which extends outward from the plane of said intermediate recessed plate portion through said circumferential opening provided in said peripheral plate portion.

2. A deflector according to claim 1, further comprising a circumferential wall surrounding the recessed plate portion.

3. A deflector according to claim 2, wherein said circumferential wall is perpendicular to the plane of the intermediate recessed plate portion.

4. A deflector according to claim 1, wherein said circumferential opening provided in said peripheral plate portion has a width substantially identical to a width of the tongue.
