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.

Appartus to reduce pressure pulsations in a pipe line, the apparatus comprising: a central pipe adapted to be connected to the pipe line and having an inner surface; a resilient liner on the inner surface of the central pipe; a first tubular housing located substantially concentrically around the central pipe to define an intermediate chamber between the central pipe and the first tubular housing and open at each end; an opening in the central pipe closed by the liner whereby pressure variations in the central pipe may be communicated to the intermediate chamber; means attaching the first tubular housing on the central pipe; a second tubular housing, substantially concentric with the first tubular housing and defining an outer chamber, between the first and second tubular housings, extending beyond each open end of the intermediate chamber so that the outer chamber communicates with the intermediate chamber through the open ends of the first tubular housing, having end walls extending from the end of the second tubular housing; thereby defining a passageway between the first housing to the central pipe, forming the outer chamber, the end walls being spaced away from the walls of the first tubular housing, thereby defining a passageway between the first housing and the second housing and having an inlet means for introducing a gas into the outer chamber so that a selected pressure may be maintained within the intermediate and outer chamber.
