The pulsation damper includes an inlet connection element, an outlet connection element and a line connecting the elements whereby these three components are connected to at least two damper chambers inside the pulsation damper, the damper chambers being connected in series inside the damper housing. One section of the line connected to the inlet connection element includes a connection channel to a first damper chamber and is joined to a second damper chamber via an inlet throttle element. The second damping chamber is connected to the outlet connection element via an outlet throttle. Damper elements made of an elastic material are disposed within the damper chambers.
