Description

SECURITY BLOCKING SYSTEM FOR PREVENTING UNAUTHORIZED USE OF FUEL ENGINE EQUIPMENTS, IN PARTICULAR OF MOTOR-VEHICLES
Field of the Invention
The invention relates to a security blocking system intended to prevent unauthorized use of fuel engine equipments, e.g. cars. The invention is based on a safety magnet valve comprising a valve chamber and an electromagnet controlled valve insert.
Background of the Art
Safety means to hinder unauthorized persons using strange cars and motorcycles and so to prevent stealing of vehicles are known. Such means are e.g. the steering lock and the headlock, the essence of which is the mechanical fixing of the steering mechanism, and/or the steering wheel and the handlebar, respectively.
Other types of safety means are intended to fix one of the foot pedals of the car, the accelerator, the brake and/or the clutch. It is a wide-spread solution e.g. fixing the brake pedal to the steering wheel by means of a steel bar with curved ends and a security lock which can be locked in such a position that the curved ends catching the brake pedal and the steering wheel don't allow removing the steel bar. All the above solutions aim at mechanical blocking the operation of one or more control means of the vehicle. Their deficiency is, that trained thieves can unlock or cut the blocking members by means of simple hand tools. Using a connecting steel bar between the steering wheel and one of the foot pedals is incomfortable: it takes up place in the car and its locking/unlocking is slow. In order to increase the security of known mechanical safety means they are often combined with electrical sound alarm. These systems don't provide calming protection either since they can be inactivated in a few seconds. Moreover, these electrical alarms are rather expensive.
Disclosure of the Invention
The invention is intended to provide an improved security system against unauthorized use of fuel engine equipments, in particular of motor-vehicles, which eliminates deficiencies of known solutions, is applicable for any customary motor-vehicle and doesn't need too much expenditure.
The invention is based on the recognition that the operation of a fuel engine can be hindered most effectively by interrupting its fuel supply. So the problem has been ameliorated by providing a security blocking system which is suitable for alternate interrupting of fuel supply of the engine.
The security blocking system according to the invention comprises a magnet valve having a valve chamber placed in the fuel supply system between the fuel feed pump and the engine, and an electromagnet controlled valve insert for alternate interrupting of the fuel supply, wherein the circuit of the magnet coil of said electromagnet is provided with a control switch being operatively combined with a security lock The security lock is arranged so that the operator (driver) can easily set the required position. In order to increase security, it can be arranged e.g. inside of a car on a secret place. Advantageously, the security lock is operated by key. In first position of the security lock the control switch is open, no current flows through the magnet coil of the electromagnet and the valve insert cuts off the way of fuel supply. In second position of the security lock the control switch is closed, the electromagnet operates and the magnet valve allows free fuel flow from the fuel feed pump to the engine.
In a preferred embodiment of the invention the chamber of the magnet valve is built together with the fuel feed pump, keeping a single integrated armature.
The magnet valve can be also connected to any other apropriate point of the fuel supply system, e.g. to the suction stub of the fuel supply pump or to the carburetor.
Advantageous Effects of the Invention
Operating the engine without using the key of the security lock needs considerable efforts intended to disconnect the magnet valve: opening the motor case, mounting some parts of the engine, connecting the fuel supply pipes, etc. These works take time and need special tools. So the invention makes the unauthorized use of the protected engine rather difficult, and increases security hereby. The invention is simply realizable, without too much expenditure.
Description of a Preferred Embodiment
The invention is described in detail below - by way of example only - with reference to the accompanying drawings, in which: Fig.1 is a partly sectional side view of a preferred embodiment of the invention, F ig .2 is a plan view of F i g .1 ; The figures show that the system according to the invention comprises a magnet valve 2 joined to a fuel feed pump 1. The fuel feed pump 1 is in connection with the engine (not shown in the drawings) through fuel supply pipes, carburetor etc. The valve chamber 3 of the magnet valve 2 is built together with the case of the fuel feed pump 1, keeping a single integrated armature.
The valve chamber 3 has an inlet and an outlet which are connected to the fuel feed pump 1 and the fuel supply pipe, respectively. The magnet valve 2 comprises an electromagnet controlled valve insert 4 which alternatively interrupts fuel supply from the fuel feed pump 1. A control electromagnet 5 is also arranged in the valve chamber 3. If there is no current flowing through the magnet coil of the electromagnet 5, the valve insert 4 is pressed onto a valve seat 6 by spring force, and interrupts fuel supply. If current flows through the magnet coil, the electromagnet 5 is activated, it pulls the valve insert 4 from the valve seat 6 against the spring force. In this last position of the valve insert 4 the magnet valve 2 allows free fuel flow and the engine can operate. The spring force is exerted by a spring 7 arranged inside the valve insert 4.
The electric circuit of the magnet coil of the electromagnet 5 involves a switch (not shown) which is operated by a security lock. In a simple embodiment the switch is connected in series to the starting switch of the engine. In this case the control switch of the security blocking system can be combined with the starting switch and operated (activated/inactivated) by using the starting means of the engine, e.g. the ignition key of a car.
Industrial applicability
The invention is applicable for preventing unauthorized use of a very wide range of fuel fed engines: it can be easily mounted e.g. into large industrial equipments or different whicles with fuel engines. Its use is particularly suggested for protection of cars and motor-cycles against stealing.
