1. An electrohydraulic motor vehicle brake system comprising:
a reservoir configured to store fluid of the electrohydraulic motor vehicle brake system;
a master brake cylinder; and
a valve arrangement coupled between the master brake cylinder and the reservoir, the valve arrangement comprising an assembly of:
a closure plug, wherein the closure plug comprises a recess extending in a vertical direction of the closure plug;
a valve carrier fastened to the closure plug, the valve carrier comprising:
a non-return valve configured to supply pressure via flow of the fluid from the reservoir to the master brake cylinder and block pressure via flow of the fluid from the master brake cylinder to the reservoir; and
a fixed diaphragm configured to control pressure in the electrohydraulic system via flow of the fluid, wherein the non-return valve and the fixed diaphragm are connected in parallel between the master brake cylinder and the reservoir; and
a sleeve projection extending in a vertical direction of the valve carrier and extending into the recess of the closure plug the sleeve projection including the fixed diaphragm; and
a cavity of the assembly disposed between the valve carrier and the closure plug, the cavity configured to establish a pressure medium connection between the master brake cylinder and the reservoir.
