Abstract
For a motor vehicle, a compressed air preparation device includes a pressure line configured to conduct compressed air, a drying device disposed in the pressure line, a governor valve coupled to the drying device, and an electrically actuatable solenoid valve, the governor valve being (i) pilot controllable by the solenoid valve at a high pressure level to allow the compressed air to be fed through the pressure line when the solenoid valve is actuated and (ii) configured to control regeneration of the drying device in response to a low pressure level from the solenoid valve when an electrical supply to the solenoid valve fails.

A compressed air preparation device comprising:
- a pressure line configured to conduct compressed air;
- a drying device disposed in the pressure line, a pressure-actuatable governor valve coupled to the drying device;
- and an electrically actuatable solenoid valve, the governor valve being (i) pilot controllable by the solenoid valve at a high pressure level to allow the compressed air to be fed through the pressure line when the solenoid valve is actuated and (ii) configured to control regeneration of the drying device in response to a low pressure level from the solenoid valve when an electrical supply to the solenoid valve fails.
