发明名称 A CONTROLLED SAFETY VALVE
摘要 <p>A safety valve for walls and other vessels and adapted to vent the vessel to the atmosphere upon the development of a predetermined maximum pressure in the vessel comprises a step plunger carrying a valve member and adapted to displace the valve member toward and away from a seat in a valve housing in which a command chamber is defined between an axial guide for the plunger and an end thereof. The command chamber is controlled by the pressure from the pilot device and the blocks surrounding this axial guide and is connected to the plunger so that the sealing is effected by the bellows and the guide does not need to have a sealing capability.</p>
