THROTTLE VALVE OF VACUUM SYSTEM

摘要

PURPOSE: A throttle valve of vacuum system is provided to preventing the first and second support blocks from being lost or damaged by physical force in a process for correcting the error of the throttle valve by fixing the first and second support blocks while using a screw. CONSTITUTION: A body(20) is supported in a portion connected to a vacuum line to which vacuum pressure is delivered, capable of rotating with respect to a supported portion. The first support block(22) is of a type extending from the portion by which the body is supported. One surface of the second support block(24) of a rectangle type is closely attached to one surface of the first support block. The second support block is fixed to the first support block by a coupling unit(26).
