The pressure modulator modulates an output pressure, in particular a brake pressure, on the basis of the input pressure and depending on the electric and/or pneumatic signal, and in the process releases compressed air via the at least one pressure-modulator venting interface. The adapter module includes an adapter having a through-opening, a first adapter interface and a second adapter interface, and a line, wherein the through-opening leads into the first adapter interface, which is configured to be releasably connected to the at least one pressure-modulator venting interface, and wherein the through-opening leads into the second adapter interface, which is configured to be releasably connected to the line or to be connected to the line. ## Claims ### Claim 1 An adapter module configured to be connected in place of a muffler module at at least one pressure-modulator venting interface of a pressure-modulator housing of a pressure modulator, which modulates an input pressure and is controlled by an electric and/or pneumatic signal, of a pneumatic or electropneumatic brake of a vehicle, wherein the pressure modulator modulates an output brake pressure based on the input pressure and depending on the electric and/or pneumatic signal, and in the process releases compressed air via the at least one pressure-modulator venting interface, the adaptor module comprising: a) an adapter having a through-opening, a first adapter interface, and a second adapter interface; b) a line, c) wherein the through-opening leads into the first adapter interface, which is configured to be releasably connected to the at least one pressure-modulator venting interface, and d) wherein the through-opening leads into the second adapter interface, which is configured to be releasably connected to the line or to be connected to the line. ### Claim 2 (depends on 1) The adapter module as claimed in claim 1, wherein the line is a hose or pipe. ### Claim 3 (depends on 1) The adapter module as claimed in claim 1, further comprising: at least one sealing element which seals off the first adapter interface of the adapter from the at least one pressure-modulator venting interface. ### Claim 4 (depends on 1) The adapter module as claimed in claim 1, further comprising: at least one securing element configured to secure the first adapter interface of the adapter to, or to retain it at, the pressure-modulator venting interface. ### Claim 5 (depends on 1) The adapter module as claimed in claim 1, wherein a) at the first adapter interface of the adapter and/or b) on the securing element, a first part of a form-fitting and releasable connection is formed so that the first part is connectable in a form-fitting and releasable manner to a complementary second part of the form-fitting and releasable connection of the at least one pressure-modulator venting interface. ### Claim 6 (depends on 5) The adapter module as claimed in claim 5, wherein the first part is part of a bayonet coupling. ### Claim 7 (depends on 1) A module system of a pneumatic or electropneumatic brake device of a vehicle, comprising: a) at least one pressure modulator, which modulates an input pressure and is controlled by an electric and/or pneumatic signal, wherein the pressure modulator has a pressure-modulator housing with at least one pressure-modulator venting interface and modulates an output brake pressure on the basis of the input pressure and depending on the electric and/or pneumatic signal, and in the process releases compressed air via the at least one pressure-modulator venting interface; b) at least one adapter module as claimed in claim 1; and c) at least one muffler module having a muffler interface, d) wherein the first adapter interface of the adapter module or of the adapter and the muffler interface of the muffler module are formed in a complementary manner such that, at the at least one pressure-modulator venting interface, either the adapter module is connectable to the first adapter interface or the muffler module is connectable to the muffler interface. ### Claim 8 (depends on 7) The module system as claimed in claim 7, wherein the pressure modulator is a pressure control module, a trailer control module or a relay valve. ### Claim 9 (depends on 7) The adapter module as claimed in claim 7, wherein: a) at the first adapter interface of the adapter or on the securing element, a first part of a form-fitting and releasable connection is formed, and b) at the at least one pressure-modulator venting interface, a second part, formed in a complementary manner to the first part, of the form-fitting and releasable connection is formed, such that c) the first part is connectable in a form-fitting and releasable manner to the second part. ### Claim 10 (depends on 9) The module system as claimed in claim 9, wherein the first part and the second part are each in the form of part of a bayonet coupling. ### Claim 11 (depends on 7) A pneumatic or electropneumatic brake device of a vehicle comprising at least one module system as claimed in claim 7. ### Claim 12 A method of connecting a module system having an adapter module, having a pressure modulator which modulates an input pressure and is controlled by an electric and/or pneumatic signal, wherein the pressure modulator has a pressure-modulator housing with at least one pressure-modulator venting interface and modulates an output brake pressure on the basis of the input pressure and depending on the electric and/or pneumatic signal, and in the process releases compressed air via the at least one pressure-modulator venting interface, and having a muffler module, on a vehicle, the method comprising: with the at least one pressure modulator venting interface, either: a) a first adapter interface of the adapter module is connected and one end of a line is connected to a second adapter interface, and the line is arranged on the vehicle such that the other end of the line is at a higher level on the vehicle in the use position than the at least one pressure-modulator venting interface or the second adapter interface, or b) a muffler interface of the muffler module is connected. ### Claim 13 (depends on 1) A method for using the adapter module as claimed in claim 1, on the pressure modulator, wherein the at least one pressure-modulator venting interface is releasably connected to the first adapter interface of the adapter module instead of an alternative connection to the muffler module. ### Claim 14 (depends on 13) The method as claimed in claim 13, wherein one end of the line is connected at the second adapter interface of the adapter module and the line is arranged on the vehicle in the use position such that the other end of the line is at a higher level on the vehicle than the at least one pressure-modulator venting interface or the second adapter interface.
