Supercharges with torsion damping
This patent describes a rotary blower of the backflow type. It comprises: a housing; first and second rotors rotatably disposed in the housing and having meshed lobes for transferring relatively low pressure inlet port air to outlet port air controllable between relatively low and high pressures; first and second meshed timing gears respectively fixed to the first and second rotors for preventing contact of the meshed lobes and positioned for rotation about an axis common to the axis of their respective rotor; an input drive adapted to be rotatably driven about an axis common to the first timing gear and in one direction at speeds proportional to speed of a periodic combustion torque transmitting engine selectively controllable between relatively low and high speeds.
