摘要：
The invention relates to a pump unit (1) that can be driven by an electric motor, in particular for providing vacuum for a pneumatic brake booster, comprising a pump housing (3) that can be closed by a working-chamber cover (2) and at least one elastic displacement element (4), wherein a working chamber (5) is bounded between the displacement element (4) and the working-chamber cover (2) and wherein inlet valves (6) and outlet valves (7) and inlet channels (8) and outlet channels (9) associated with the valves are associated with the working chamber. According to the invention, in order to reduce noise emissions, means for reducing a contact surface between the working-chamber cover (2) and the pump housing (3) are provided.
