The electrohydraulic booster contains an electromechanical converter 19, to which caps 26, 27 are mechanically connected. Arranged coaxially to the caps 26, 27 are nozzles 13, 14, to which a basic spool 2 and a three-position auxiliary spool 16 are connected. The three-position auxiliary spool 16 can be displaced to an extent which exceeds the width of its grooves 17, 18, passages 32, 33 being provided in this auxiliary spool. Throttle resistors 34, 35 are assigned to the passages 32, 33 in accordance with the number of nozzles 13, 14, and the passages 32, 33 are connected to the grooves 17, 18 and nozzles 13, 14. <IMAGE> |
