Abstract
A water pump has a check valve with a valve body movable in a direction of a valve axis of the check valve between an open position of the check valve and a closed position of the check valve. An actuating device is connected with the check valve and has an operating element that is movable coaxially to the valve axis. The operating element is operatively connected to the valve body and arranged such that the operating element, by applying a coaxial force to the valve body, transfers the valve body into a venting position of the check valve.
