Abstract

A 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 fluid outlet opening are dedicated to the pump chamber. The pump housing includes a closed stroke ring, a first separate thrust washer, and a second separate thrust washer. At least one stroke ring adjustment device axially clamps the closed stroke ring directly to the first separate thrust washer. At least one separate housing clamping device axially clamps the first separate thrust washer, the closed stroke ring, and the second separate thrust washer together.
