Abstract (en)

[origin: EP0907031A2] The arrangement includes a control pump for conveying a hydraulic fluid, and at least one associated valve which is formed as a switching valve (5), electrically controllable in conjunction with the pump (2) in such way, that the volume conveyed by the pump is adjusted to the need of the hydraulic cylinder (1). The valve and the pump are preferably connected with an electric control unit (11).
