Increasing tire inflation pressure function

Select the relevant axle or all the axles with the selector switch. Then switch the "Inflate/deflate" switch to inflate. The 3/2-way valve (33.01a) and the 2/2-way valves (45.01a) are energized electrically.

The solenoids switch the directional valves to passage (inflate), the compressed-air can therefore flow out of the compressed-air reservoir (5.01) into the tires.

By inflating, the connection to the bypass valve with limited backflow is closed via the shuttle valves (28.03).

The tire pressures at the front and rear axle can be read off on the two pressure gauges (11.01, or 11.02 on 437.156) in the cab.
