Abstract

A potentiometer chamber on the intake pipe wall of an internal combustion engine for containing an electrical potentiometer. The potentiometer chamber comprises a limiting wall, formed by the intake pipe wall, a sidewall extends thereto from which serves as lateral limits of the chamber. A partition made by injection molding from plastic, into which are embedded electrical contacts extends from the sidewall and a lid is placed on the partition. Therefore the limiting wall, the sidewall, the partition, and the lid form the chamber that encloses a potentiometer.
