Throttle assembly and pressure control system having such a throttle assembly

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 of a range of volume flows 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,
• wherein the pneumatic load is connected to the throttle assembly,
• wherein the throttle assembly has a parallel circuit containing the at least one throttle valve,
• wherein the at least one throttle valve includes at least two throttle valves , each of the at least two throttle valves having a throttle valve cross section,
• wherein at least one of the at least two throttle valves in the parallel circuit is configured to be switched to a closed position under pneumatic or electric control in accordance with the upstream pressure to allow upstream-pressure-dependent setting of the assembly cross section, and
• wherein the assembly cross section is obtained from a sum of those throttle valve cross sections to which an open throttle valve of the parallel circuit is assigned.
