Abstract
PURPOSE: To make compact the pulsation absorbing means, by converting the pressure waves from sound system into mechanical system, in the suction air quantity measuring unit for internal combustion engine utilizing the Karman's vortex.
CONSTITUTION: At the down stream of the vortex column placed in the suction air pas 1, the variable volume chamber 7 is placed in connection to the suction air duct 1. When the slottle valve 5 is fully opened, the traveling wave of negative pressure from the suction valve of the engine passes through the slottle valve 5. The pressure wave through the duct 6 enters the variable volume chamber 7 and converted from sound system into mechanical system by moving the movable barrier 8 and it is absorbed with the inertance and compliance given to the movable barrier 8.
