摘要： A vehicle anti-theft system in the form of a mechanically interengagable electronic key and lock includes stored key and vehicle identifiers in both the key and in the lock. A random number is generated in the lock each time the vehicle ignition switch is closed and that random number is used to encode one of the identifiers for transmission to the key. The key uses the corresponding stored identifier to recover the random number. The other stored identifier is then encoded using the recovered random number and the encoded other identifier is returned to the lock. The lock uses the generated random number to recover the second identifier for comparison to its stored value. If the comparison fails, vehicle operation is prevented. The system may effect several trials, each using a new random number before refusing further attempts. The lock electronics is preferably disposed in the vehicle fuel tank and controls operation of the vehicle fuel pump.

摘要： A security device (2) particularly for a motor vehicle which is adapted to isolate the fuel supply from the engine of the vehicle. The security device (2) includes a first body member (6) locatable at one side of a vehicle floor (10) and a second body member (8) locatable at an opposite, second side of said floor (10), said body members (6, 8) being securable together through said floor (10) by means (12) located at said second side engaging means (14) extending from a lower surface of said first body member (6), a rotatable locking device (26) located in said first body member (6) and a rotatable valve member (46) located in said second body member (8) and being movable, upon rotation of said locking device (26), from a first position allowing fuel to flow through said valve member (46) to a second position preventing such flow, the security device (2) being devoid of any release means at said one side of said vehicle floor (10).

摘要： In the duct (5) carrying the fuel flow there is arranged a shaped piston (4) comprising an upper bellows (11) which engages with a central coaxial control stem (10).
The piston is driven by an operator (2) whose intervention is conditioned by activation or not of an anti-theft device. With the operator (2) in neutral position or with the anti-theft turned on, the piston (4) closes the fuel passage port. With the operator in working position, i.e. with the anti-theft device excluded, it is extended, the piston rises and the passage port (7) opens. Under these conditions the pressure differential between upstream and downstream, apart from the direction of flow, arranges itself both in the direction of flow and upstream and downstream of the central zones delimited and separated by said upper bellows (11). The pressure differential arranges the central control stem (10) in a position of adherence with a ring of balls (9) which, thrust radially outward, are engaged in a peripheral seat (13). Said engagement prevents the piston (4) from returning to its neutral position even if the operator (2) should return inward because of, for example, breakage. The fuel flow continues thus for the entire period that the vehicle keeps the motor running, i.e. as long as the status of pressure head between upstream and downstream of the stem (10) prevails. Upon stopping of the motor, i.e. upon elimination of the pressure differential, the piston (4) is thrust into the closed position by a counteracting spring (6) which relaxes from its compressed condition.

摘要翻译： 在承载燃料流的管道（5）中布置有一个成形的活塞（4），其包括与中心同轴控制杆（10）接合的上部波纹管（11）。 活塞由操作者（2）驱动，操作者（2）的干预由激活而不是防盗装置进行调节。 当操作员（2）处于中立位置或防盗开启时，活塞（4）关闭燃油通道。 在操作者处于工作位置的情况下，即除去防盗装置之外，其延伸，活塞升起并且通道口（7）打开。 在这些条件下，除了流动方向以外，上游和下游之间的压差本身都在流动方向上，并且由所述上部波纹管（11）限定和分离的中心区域的上游和下游排列。 压力差将中央控制杆（10）布置在与径向向外推动的环（9）的接合环周边座位（13）的位置上。 即使操作者（2）由于例如破损而向内返回，所述接合也防止活塞（4）返回其中立位置。 因此，在整个车辆保持电动机运行的整个时期内，即只要阀杆（10）的上游和下游之间的压力头的状态占上风，燃料流就会持续。 在停止电动机时，即消除压差，活塞（4）通过从其压缩状态松弛的反作用弹簧（6）推入关闭位置。
