Abstract:
An arrester for inhibiting hammer caused by interruption of fluid flow in conduits comprises a hollow cylindrical body closed at one end and open at the other. A piston is freely slidable within the body forming with the closed end thereof an hermetically sealed gas chamber. A connector connects the open end of the body with the conduit conveying fluid under pressure. Under fluid hammer conditions, the piston is advanced against the gas in the gas chamber. This forms a cushion which absorbs the shock and prevents the development of fluid hammer.
