Valve arrangement for supplying a hydraulic consumer with pressure medium, which valve arrangement has two working connectors (A, B) for the fluid connection to the consumer, with a first control valve which - has a first feed line (24), via which a first feed stream from the first working connector (A) to the consumer (10) can be controlled, and with a first return control restrictor (26), via which a first return stream (28) from the consumer (10) via the second working connector (B) can be controlled at the same time as the first feed line (24), and - has a second feed line (34), via which a second feed stream from the second working connector (B) to the consumer (10) can be controlled, and with a second return control restrictor (36), via which a second return stream (38) from the consumer (10) via the first working connector (8) can be controlled at the same time as the second feed line (34), and with a second control valve (40) with a feed control restrictor (42), by way of which the respective feed line (24, 34) of the first control valve (20) can be controlled.
F15B 11/024 - Systems essentially incorporating special features for controlling the speed or the actuating force or speed of an output member by means of differential connection of the servomotor lines, e.g. regenerative circuits
