METHOD AND APPARATUS FOR REGULATING NEGATIVE-PRESSURE FEED INTAKE OF AN AIR INTAKE SYSTEM

摘要

Provided is a method for regulating a negative-pressure feed intake of an air intake system; inside an intake pipe disposed on a machine having an air intake system and an air exhaust system are arranged at least one one-way valve (1), and at least one connecting rod assembly (21, 22) which is connected to the one-way valve (1), has at least one different axis of rotation, and has an appropriate restoring force; the above form a one-way valve assembly which opens/closes via actuation according to an air flow; by means of the one-way valve assembly, the negative-pressure feed intake and negative-pressure source intake of the air intake system are regulated. Also comprised is an apparatus for regulating a negative-pressure feed intake of an air intake system. The method and apparatus improve air intake effectiveness and conserve energy.
