摘要：
A pump device having a vane-type pump has a check valve in a fluid duct which leads from a pressure region to an under-vane region. The check valve blocks in the direction of the pressure region, preventing pressure from escaping from the under-vane region into the pressure region during the start-up of the vane-type pump.
