Choke fabricating method for heat engine of motor vehicle, involves molding kinematic block using mold, molding end piece using another mold that is different from former mold, and arranging kinematic block with end piece to form choke

摘要

The method involves molding a kinematic block (32) with a gas pipe (34) by using a mold, where the gas pipe is connected to another gas pipe (36) housed in an end piece (38). The end piece is molded using another mold that is different from the former mold. The kinematic block is arranged with the end piece to form a choke (30) for an engine of a motor vehicle, where the kinematic block and the end piece are molded using polymeric material such as thermoplastic material or thermosetting material.
