    Abstract: A device for stopping an approaching target vehicle by deflating the vehicle’s tires. The device has a scissor-like extendable and retractable construction with upward facing spikes. After deployment, the deflator may be retracted automatically and/or by the push of a button. The deflator can be stored in the enclosure to which it is attached. The deflator is extended by pushing a central hinge of the scissor construction forward, almost completely out of the enclosure. The propulsion means is actuated by a compressed gas capsule, preferably carbon dioxide, and an air cylinder with a linear movable piston connected to the deflator. The gas capsule releases gas under pressure to the air cylinder and moves the piston in a first direction, thereby extending the deflator. By leading compressed gas of the gas capsule to the opposite side of the cylinder, the piston moves in the opposite direction and the deflator is retracted.
