    • A pneumatic actuator is provided for an active hood and includes, but is not limited to a cylinder and a piston, which is movable in the cylinder between a lower terminal position, in which the volume of a chamber delimited by piston and cylinder, which may be impinged using compressed gas, is minimal, and an upper terminal position, in which the volume of the chamber is maximal. The piston is lockable in the lower terminal position by a detent body engaging in first recesses of the cylinder and the piston. A slider is displaceable by impingement using the compressed gas out of an idle position, in which it fixes the detent body in the first recesses, into a triggering position, in which a second recess of the slider overlaps with one of the first recesses and is capable, together with a single one of the first recesses of accommodating the detent body.
    • 气动致动器设置用于主动罩,并且包括但不限于气缸和活塞,其可在气缸中移动,下端终端位置之间由活塞和气缸限定的室的容积 使用压缩气体撞击,是最小的,并且上部终端位置,其中室的体积最大。 活塞通过与缸体和活塞的第一凹部接合的止动体可锁定在下端子位置。 滑块可以通过使用压缩气体从空闲位置移动,该空闲位置将其中的棘爪本体固定在第一凹部中的触发位置中,滑动件的第二凹部与第一凹部之一重叠, 能够与容纳止动体的第一凹部中的单个一个一起。
