A damper element for damping pressure pulsations in a liquid includes a first side including a first wall portion at least partially defining a chamber containing a gas and a second side including a second wall portion at least partially defining the gas-containing chamber. The second side is overlappingly joined with the first side such that the first and second wall portions combine to define substantially an entire cross-section of the gas-containing chamber. Both the first and second wall portions are convexly curved outwardly away from the gas-containing chamber.
