The invention of the safety valve.

definition

A safety valve is a device to ensure the safety of equipment operating under high liquid, gas, or steam pressure when damage to the equipment may result from exceeding the established operating pressure. Safety valves are installed on steam boilers, compressed air receivers and various technical devices and pipelines operating under pressure[1].

INVENTION

The German-Dutch chemist Johann Rudolf Glauber invented[2] the safety valve in 1651 after trying to solve the problem of glass vessels bursting from increased pressures. Here is a drawing[2] of his safety valve and an animation that shows how it works:
