Abstract (en)
[origin: EP1101949A2] The control device controls the hydraulic volume flow (10) of at least one fluid (12) and has a locking valve with main valve body (14) and fine control (18), and with a pre-control valve body (22) operated by a setting element. At least one throttle cross section of a throttle point (38) narrows towards the beginning of the opening stroke of the main valve body.
