CONTROL SYSTEM, SPRAY BAR, CARRIER AND METHOD OF IMPLEMENTATION
First Claim
1. A hydraulic control system configured to control an angle of an inclinable part of a spray bar mounted on a carrier, the control system comprising:
- an actuator configured to change the angle of the inclinable part of the spray bar;
a pump in fluid communication with a reservoir, the pump configured to control the actuator using fluid stored in the reservoir;
a first accumulator and a second accumulator, each of the first and second accumulators in fluid communication with the actuator and configured to dampen vibrations of the spray bar and thus to stabilize the angle of the inclinable part of the spray bar; and
a distributor in fluid communication with both the first accumulator and the second accumulator and with the pump, the distributor configured to be in either a circulation position or a non-return position;
wherein when the distributor is in the circulation position fluid flows through the distributor to maintain equal pressure in the first accumulator and the second accumulator.

Abstract
The present invention relates to a control system (20) provided to a spray bar (10) mounted on a carrier (1) at an angle (α10) adjustable relative to the carrier (1), the control system (20) comprising an actuator for changing the angle (α10) of the spray bar (10); a control device for controlling the actuator; and a damping device connected to the actuator to damp vibrations and oscillations of the spray bar (10) and thus stabilize the angle (α10). The invention is characterized in that the control system (20) further comprises a recharging device operating simultaneously with the control device to compensate for a pressure change in the damping device during a change in the angle (a 10) of the spray bar (10). The invention also relates to a spray bar (10), a carrier (1) and a method of implementation.
