Abstract
A vane type gas pump for a compressible fluid. The vane-type gas pump includes a pump housing which forms a pump chamber in which a pump rotor with at least one slidable sliding element is rotatably mounted. At least one fluid inlet opening and at least one elongated fluid outlet opening are dedicated to the pump chamber. The at least one slidable sliding element has a tangential width. The at least one elongated fluid outlet opening has a tangential width. The tangential width of the at least one slidable sliding element at least corresponds to the tangential width of the at least one elongated fluid outlet opening so that the at least one slidable sliding element temporarily completely covers the at least one elongated fluid outlet opening.
