Porsche, is the pipe from the air pump to the distribution valve an air pipe?

Porsche replaced the air pump with a distribution valve with an air pipe. The distribution valve is as important as the human heart in air braking. If it fails, the air braking function of the whole vehicle will completely fail, and the driving safety will not be guaranteed. The hydraulic pump sends the pumped high-pressure oil to the distribution valve to perform the required action. The control valve lever of the rotary bucket cylinder has three positions: up, hold and down.

Function of distribution valve

Play the role of connection and distribution. Each branch pipe is connected with the main pipe through the distribution valve, which is the connection function; Moreover, the source of the main pipeline is distributed to each outlet pipe through the distribution valve. Working principle of the distribution valve: the distribution valve controls the inflation and exhaust of the action air cylinder according to the pressure change in the train pipe, and realizes the braking, pressure maintenance or pressure relief of the locomotive through the actions of the directional valve and the action valve.
