Delay valve in automotive application Iveco vehicles equipped with vacuum booster, which allows car even at low speed, light brake pedal, it will also result in higher braking effect, which causes the front wheel brake system is too sensitive, easy to hold dead drag slip, reducing driving stability. To avoid these shortcomings, the car's front brake circuit in the installation of a delay valve. Only the pressure of 0.14MPa, this only allows the brake fluid through the valve, the pressure just started to open the brake shoe. Pressure in the brake master cylinder prior to 1.26MPa, the pressure remains constant, the pressure exceeds this value, the lag valve is opened, the brake fluid normally sparse moving to the front brake circuit, if the time step on the brake pedal is in the end, we can achieve the maximum allowable pressure of the brake system to achieve the braking effect of the segment.

依维柯汽车装有真空助力器,它可使汽车既使在低速行驶,轻踩制动踏板时,也会产生较高的制动效应,这会导致前轮制动系统过于敏感,易抱死拖滑,降低行驶稳定性。为了避免这些缺陷,在汽车的前制动回路中安装了一个滞后阀。只有压力达到0.14MPa时,此阀才允许制动液通过,这一压力刚好可以使制动蹄开始张开。在制动主缸压力达到1.26MPa之前,这一压力保持不变,压力超过此值,滞后阀打开,制动液正常地疏动到前制动回路,若此时制动踏板已踩到底,便可达到制动系统允许的最大压力,实现制动的分段作用。
