发明名称 Pneumatic actuator
摘要 A pneumatic actuator is provided for an active hood and includes 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.
