Exhaust gas flow rate regulation valve i.e. exhaust gas recirculation valve, for internal combustion engine of vehicle, has pipe portion including ends cooperated with units, to connect turbocompressor and sump, and integrated to valve

摘要

The valve (6) has an oil return pipe portion (30) whose ends are cooperated with a connecting unit (310) i.e. mounting end piece, and another connecting unit (320), to connect a turbocompressor and an oil sump of an internal combustion engine of a vehicle, where the pipe portion is rigid and integrated to the valve. The oil return pipe portion is molded with the valve by casting. Oil pipes (31, 32) are assembled to the corresponding connecting units by hose clamps, and are made of flexible material.
