Abstract

Control valve which, in a generally cylindrical and compact body, encloses a first seat for a first shaped slider for controlling ports for pressurised fluid directed alternately to an actuator cylinder, a device for modulating the flowrate to the said cylinder, a first valve lens for activating the latter's decent and a second for controlling the speed of this decent, which control valve enables an appliance to continuously follow and transform the contours of the worked land. <IMAGE>
