Abstract (en)
[origin: EP2453112A1] The adjuster (2) has a control valve (18) comprising a pressurizing agent-port (P) for supplying pressurizing agent and a tank-port (T) for conveying the pressurizing agent. A pressure-controlled positioning valve (38) is connected with a control chamber pair (4), which comprises smaller and larger control chambers (A, B). The positioning valve is formed in such a manner that the smaller control chamber is connected with a supply line (56) and the larger control chamber is connected with a drain outlet (58) at an unenergized basic position (19a) of the control valve.
