Summary:Element for compressing a gas with a housing (2) with an inlet (3) and an outlet (4), which housing (2) encloses a compression chamber (5) with an outlet port (7) connected to the outlet, wherein in the compression chamber (5) a rotor (8) is mounted so that the compression chamber (5) is divided into working chambers, wherein the element (1) is provided with a passage (10) between the outlet and a working chamber in the compression chamber (5) which is not in adjacent contact with the outlet port (7), which passage (10) is provided with an overpressure valve (11) to open the passage (10) when a pressure difference between the working chamber and the outlet (4) exceeds a preset value, characterized in that the overpressure valve (11) comprises a valve body (12) that encloses a buffer space (13) with a variable volume that is in fluid connection with the outlet through a constriction (14), so that this volume is reduced and gas from the buffer space (13) flows through the constriction (14) to the outlet upon opening the passage (10).
