ABSTRACT:
An intake head device for an internal combustion engine, which is suitable for impulse charging and/or residual exhaust gas purging, including a pressure accumulator (24) which may apply overpressure to the pressure passage via a pressure passage, so that this produces residual exhaust gas purging of the cylinder (16) when the inlet valve (18) is open and the impulse flap (21) is closed. The impulse charging is performed by a partial vacuum which is generated in the accumulator passage (22) by the air intake of the cylinder (16). The pressure accumulator arrangement of the invention has the advantage that the closing time of the flap (21) may be longer.
