Abstract

A silencer assembly primarily for the passage therethrough of exhaust gases from an adsorption dryer tower comprises a silencer element to one end of which pressurized gas is directed from an outlet, a control valve downstream of the silencer element, and means for restricting the flow of pressurized gas from the outlet to atmosphere through the silencer element, the arrangement being such that, when the pressure of the gas from the outlet exceeds a predetermined value, the control valve is closed and gas flows from the outlet into and through the silencer element to atmosphere, and, when the pressure of gas from the outlet falls to said predetermined value, the control valve opens and the gas flows from the outlet through the control valve to atmosphere, by-passing the silencer element.
