In this case, both the vacuum release valve and the stoplight switch are actuated by movement of the brake pedal. 在这种情况下,真空释放阀和制动灯开关都有刹车踏板的运动控制。
This system can detect the vacuum valve performance parameters such as the short circuit, open circuit conditions, the release and pick time of the voltage, vacuum suppression and release time, the leakage of the valve. 该系统能够检测真空阀的短路、断路情况,真空阀电压吸合与释放时间,真空打压与释放时间,阀的泄漏量等性能参数。
