Abstract

An electrically powered mechanism slides a rod, valve or other component of a valve, ram etc. having a fixed body. A closed chamber which can be distorted (1) and of variable volume, mechanically secured to the body (3) and the movable component (2) contains a fluid whose pressure is a function of its temperature. A variable-temperature heater, controlled electrically (6), to warm the fluid, may be an electrical heating resistance, inside the closed chamber. The medium contained in the chamber can be a gas in the saturated vapour state. The housing of the chamber may be a bellows, and springs may be incorporated for return movement.
