<p>A shock valve for releasing a fluid in response to an acceleration applied to the valve above a threshold value is provided. The valve includes a fixed lever arm (1) defining a sealed fluid passageway (4) therein and a floating mass (2). During acceleration the mass (2) exerts a bending moment on the arm (1) causing the arm to fracture at a weakening incorporated therein. The weakening may comprise a peripheral groove (5) formed around the arm (1). The valve has been found to perform reliably and predictably and is particlularly useful for controlling the release of cooling fluids in missiles.</p> |
