Abstract

An arrangement for dampening the pressure vibration of a fuel feed system (1 ) of a piston engine, the arrangement comprising a vibration dampener (11) having a body part (12) inside which is a space (13) containing a movably arranged intermediate piece (16), a first opening (14) arranged to open in the space (13) on the first side of the intermediate piece (16) for connecting the space (13) with the fuel feed system (1 ), and a second opening (15) arranged to open into the space (13) on the second side of the intermediate piece (16), the second opening (15) being in flow connection with a gas source (22) comprising pressurized gas.
