Abstract
An element for compressing a gas with a housing () which encloses a compression chamber () with an outlet port () connected to the outlet. A rotor () is mounted so that the compression chamber () is divided into working chambers. A passage () extends between the outlet and a working chamber in the compression chamber () which is not in adjacent contact with the outlet port (). The passage has an overpressure valve () to open the passage when a pressure difference between the working chamber and the outlet () exceeds a preset value. A valve body () encloses a buffer space () with a variable volume that is in fluid connection with the outlet through a constriction (), so the volume is reduced and gas from the buffer space () flows through the constriction () to the outlet upon opening the passage ().
