Abstract
A hydraulic control circuit of a double-acting orientation cylinder to orient fan blades of a turbojet engine. The control circuit includes an oil tank, a variable-displacement axial piston pump including a swash plate controlled by a control cylinder comprising a control chamber and by compensation cylinder comprising a compensation chamber. The pump is supplied by the tank and has the outlet thereof connected to one of the chambers of the orientation cylinder, the other chamber of the orientation cylinder being connected to the tank, the control and compensation chambers being pressurised with a pressure corresponding to the pump outlet pressure, the control and compensation chambers being arranged to increase the tilt of the plate in order to increase the displacement of the pump when the supply pressure of these chambers increases.
