| 摘要 |
<p>The invention relates to a hydraulic circuit including devices connected to a high-pressure circuit (2) and a low-pressure circuit (16), and a booster system comprising a pump (20) taking the fluid from a tank (22) to supply the low-pressure circuit in order to maintain a minimal pressure therein, characterised by comprising a means for drawing vacuum (30) on the high-pressure circuit (2), a communication check-valve (32) arranged between the low-pressure (16) and high-pressure (2) circuits allowing the transition to high pressure, and a means for locking the pump (34).</p> |
