Abstract (en)

[origin: EP0285100A2] A rotor assembly used in an automobile supercharger includes a casing in which a rotor rototes to draw in, compress and discharge a gas. The casing and the rotor define a compression chamber, and the casing is provided with an opening over a rotational angular range of the compression chamber which includes the latter half of the rotor compression stroke, and with a passageway for communicating the compression chamber with a discharge pipe via the opening. Switching means are arranged in the passageway for opening and closing the passageway in dependence upon discharge pressure produced by the compression stroke and supercharging pressure inside the discharge pipe.
