Abstract

The control device has a chamber (5) which is disposed inside the well (P) and it is connected to a pipe (7) which leads to a pressure operated switch. On the chamber is an annular rim (7) which surrounds an aperture and is gripped between two flanges by screws. One of the screws may have a ring to allow the chamber to be anchored in the well. One of the flanges has a tubular joint to connect it to the flexible tube. The other flange has a single pair of intersecting metal strips which form a kind of cage.
