To enable or disable the latch opening the hood over a car engine, axial rod 4 is coupled to or decoupled from, axial rod 6, according to whether a finger 7 enters the small-diameter annulus 11 of a body 3. If finger 7 does not lie in space 11, pulling rod 4 leftwards will leave cylinder 2 and hence rod 6 in position. Finger 7 is attached to a diaphragm 16 which is moved by vacuum applied to conduit 19A. The vacuum source is the engine manifold. |
