Operation - The working pressure (p-A) is regulated at the working pressure regulating valve (22) depending
on the load (modulating pressure (p-Mod)) and depending on the gear (p-K1, p-K2). See Fig. 70. A minimum
level (basic pressure) is adjusted by the spring in the working pressure regulating valve (22).
