Abstract (en)

[origin: EP2128454A1] The valve (1) has fine control units (37) with a throttle channel (42) connected with a supply channel (23) or an outlet channel (24) and with a throttle channel opening (44). The control units have a fine control opening (43) whose opening cross section is larger than the throttle cross section of the throttle channel. The control opening runs into a control chamber (5) at a circumference side such that the opening cross section depends on a position of a valve slide (6) in an adjusting area of the slide and corresponds to the throttle cross section in a middle position of the slide.
