Description
Royle's steam-trap consists in the "employment of an open-bottomed condensing-chamber,... fitted to rise and fall in a suitable reservoir of water... Steam is admitted by suitable means into and beneath such condensing-chamber, and the buoyancy thus obtained is employed to actuate the necessary cock or valve in one direction, while the condensation constantly taking place within such condensing-chamber is taken advantage of to actuate such cock or valve in the contrary direction."
