Abstract

Abstract The total of the drillings' diameters equals the dia. of the smallest section of the injection channel, and the spring of the non-return valve ensures that the valve is closed against reverse flow or during a faulty injection. Air chambers are provided between the body of the equipment and the injection head as thermal insulation and the body is clad with PTFE to prevent heat loss.
