内泄漏是在液压系统内部发生的泄漏例如：液压油缸活塞两边的泄漏控制阀的阀

Internal leakage is the leakage that occurs inside the hydraulic system, <br>such as <br>the leakage <br>between the valve core and the valve body of the leakage control valve on both sides of the hydraulic cylinder piston . <br>Internal leakage will not cause loss of hydraulic oil. However, due to leakage, the established control actions will still be affected until the system malfunctions.
