Abstract

A master brake cylinder arrangement (10) for a motor vehicle brake system, comprising a master brake cylinder housing (12) with a cylindrical recess (28), at least one pressure piston (30, 32) which is displaceable and sealingly guided in the cylindrical recess (28) of the master brake cylinder housing (12), a fluid reservoir (14) which is fluidically coupled to the master brake cylinder housing (12) via a connecting region (22) and which serves for storing brake fluid, wherein the at least one pressure piston (30, 32) together with the master brake cylinder housing (12) sealingly encloses a pressure chamber (38, 40) which, as a function of the position of the associated pressure piston (30, 32), is fluidically connected to or separated from the fluid reservoir (14), wherein furthermore the at least one pressure chamber (38, 40) can be or is fluidically coupled to a fluid circuit of the motor vehicle brake system, wherein the fluid reservoir (14) in the connecting region (22) is received, in a manner sealed by means of a sealing element (62), in a receiving portion (26) of the master brake cylinder housing (12), and wherein at least one throttle element (66) is provided in the connecting region (22), which throttle element as a function of the pressure conditions in the at least one pressure chamber (38, 40) throttles or derestricts the fluid stream between the fluid reservoir (14) and the at least one pressure chamber (38, 40) through the connecting region (22). In said master brake cylinder arrangement it is provided that the at least one throttle element (66) is combined with the sealing element (62) so as to form an integral structural unit.
