Example embodiments disclose a valve seat that encloses a fluid passage for passage of a fluid from a fluid chamber, and a holding element that exerts a holding force on a valve body, the holding force acting in a direction towards a valve seat. In the event that the fluid acts on an effective surface of the valve body with a force or a pressure above a limit value, the valve body moves away from the valve seat. In the event that the fluid acts on an effective surface of the holding element with a force or a pressure above a limit value, the holding force acting on the valve body decreases. In doing so, the fluid acts on the holding element more strongly and/or earlier than on the valve body.
