    • In an automotive internal combustion engine having an exhaust cleaning catalytic converter in the exhaust system and a mixture ratio control system for controlling the air-to-fuel ratio of combustible mixture toward a predetermined value that will enable the catalytic converter to produce a maximum conversion efficiency, a valve arrangement for use in the mixture ratio control system, comprising a valve unit adapted to control the flow of fluid therethrough either cyclically or continuously and a stationary support member or structure supporting the valve unit and separate from the engine construction so that the valve unit is isolated from the vibrations produced in the engine. The valve arrangement may further comprise resilient bracket means intervening between the valve unit and the support member or structure.
    • 在具有排气系统中的排气净化催化转化器的汽车内燃机和用于将可燃混合物的空燃比控制在预定值的混合比控制系统中,使得催化转化器能够产生最大的转化效率 ,用于混合比率控制系统的阀装置,包括适于控制循环或连续流过其中的流体流动的阀单元和支撑阀单元并与发动机结构分离的固定支撑构件或结构,使得阀 单元与发动机产生的振动隔离。 阀装置还可以包括插在阀单元和支撑构件或结构之间的弹性支架装置。
