Apparatus to reduce pressure pulsations in a pipe line. The apparatus comprises a central pipe to be connected to the pipe line. There is a resilient liner within the central pipe and an intermediate chamber is substantially concentric with the central pipe and open at each end. An opening in the central pipe is closed by the liner. Pressure variations in the central pipe are thus communicated to the intermediate chamber, which is attached to the central pipe. There is an outer chamber, closed at each end and substantially concentric with the intermediate chamber, and able to maintain a selected pressure. |
