Abstract

11,988. Herman, B. R. June 8. Safety-valves.-The valve b<1> is normally kept to its seat by the pressure of steam on the piston c, which is slightly larger than the valve. Fitted in the piston are small spring-loaded valves j, which open when the pressure rises unduly, thus reducing the effective area of the piston, so that the pressure of steam on the valve b<1> preponderates and opens that valve.
