Abstract

The invention relates to a pump for pumping a fluid, including an inlet, an outlet, and a pumping chamber, wherein a valve is arranged between the inlet and the pumping chamber or between the pumping chamber and the outlet. The valve includes a valve body having a valve seat pointing in the direction of the outlet, and a valve member that interacts with the valve seat, wherein the valve member is loaded under pre-loading against the valve seat into a closed position of the valve and allows fluid to pass through in a pumping direction due to the valve member lifting off against the pre-load, wherein the valve body is accommodated in a receptacle of a pump part. A pump for which the development of noises and vibrations is reduced in that the valve body can move axially relative to the receptacle that accommodates the valve body.
