Initial position Since the engine has been shut down, there is no pressure in the hydraulic
system. The compression spring (21) has pushed the volume flow controller
(772) to the right. In this position, the top side of the variable-displacement pump
hydraulic cylinder (377) is connected with the tank via the volume flow controller
(772). The control spring (15) has swivelled the swash plate (17) to its maximum
position.
