ABSTRACT:
A supercharger of an internal combustion engine having a Roots-type pump comprising; a pair of rotors rotatably mounted in a pump housing so as to rotate synchronously in opposite directions to suck air from an air inlet and discharge it through an air outlet. The pump housing defines annular spaces around the rotor shafts and between the axial end faces of the rotors and bearings rotatably supporting the rotor shafts. The annular spaces are connected to the atmosphere via a control valve, so that the atmospheric air is introduced into the annular spaces during certain engine driving conditions to reduce the pressure difference existing around the bearings.
