Abstract:
A pulse damper for damping pressure pulses in pressurized liquids in conduits comprisinga central pipe (1) adapted to contain a pressurized fluid and having fittings (2,3) for connecting the pulse damper to a pressurized-fluid conduit requiring damping,passages (5) extending perpendicular to a longitudinal axis of the central pipe and hydraulically connecting radially outward chambers (6) formed along the central pipe to an inside space (4) of the central pipe (1), andan elastic, pressure-resistant membrane (7) adapted to transmit pressure fluctuations and extending through each chamber (6) to separate the chamber in hermetic, fluid-tight manner into a first sub-chamber (6.1) filled with a pneumatic fluid and a second sub-chamber (6.2) adapted to be filled with said liquid through the passages (5).
