Abstract

A moving plug is enclosed in a working chamber, in which there is an inlet (5) at one end inaccessible to the plug (8), and an outlet (2) at the other which it seals off when driven towards it by the fluid flowing from the inlet. A return force is exerted on the lug to thrust it clear of the outlet, typically by a return spring, or by the weight of the plug itself, or a magnet acting on the plug. The latter can be in the form of a ball smaller than the cross-section of the working chamber, so that fluid can flow between it and the chamber wall to the outlet. Alternatively it can be a hollow cylinder, working in a cylindrical section of the chamber, in whose wall the outlet is situated.
