Hydraulic unit for traction-controlled motor vehicle brake systems

Disclosed herein is an air quantity metering apparatus for use in internal combustion engines including a fuel injection system having an air intake manifold provided with a barrier flap which is mounted on a shaft to which is attached, exteriorly of said manifold, a spring loaded mechanism that serves to pretension the barrier flap in dependence upon conditions that exist in said manifold.

Air quantity metering apparatus

The air pressure in the intake valve undergoes a sudden decrease upon closure of the throttle valve. This decrease is sensed and opens a bypass which furnishes some air to the air intake means when the throttle is fully closed. The quantity of air so furnished is sufficient to allow combustion in all cylinders of the engine, thereby preventing excessive cooling.
