1. A throttle assembly for a pressure control system in a vehicle, the pressure control system having a pneumatic load, the throttle assembly comprising:
at least one throttle valve,
wherein the at least one throttle valve defines an assembly cross-section of the throttle assembly,
wherein the assembly cross-section specifies a flow resistance acting on a pressure medium entering the throttle assembly,
wherein the at least one throttle valve includes at least one controllable throttle valve configured to be controlled in accordance with an upstream pressure,
wherein the assembly cross-section of the throttle assembly is configured to be set, by control of the at least one controllable throttle valve, between a fully open and fully closed cross-section in such a way that an inlet volume flow of the pressure medium entering the throttle assembly can be limited to a limit volume flow between a zero volume flow and a full volume flow in accordance with the upstream pressure, in order to set, in accordance with the upstream pressure, a power consumption of the pneumatic load in the pressure control system, and
wherein the pneumatic load is connected to the throttle assembly.
