Description

 The invention relates to vehicle equipment and is used as a device to prevent its unauthorized use.

 A device is known for preventing the unauthorized use of a vehicle, comprising a valve blocking the air supply channels for starting the engine (RU 2098298, class B 60 R 25/04, publ. 10.12.1997).

 However, the known device is only suitable for use in a vehicle having an air supply pipe and a complex structure due to the need to control the amount of air supplied.

 The purpose of the invention is the expansion of the range of applications and simplification of design, increasing operational reliability and maintainability.

 This goal is achieved by the fact that the valve blocks the air supply channels of the primary (main) mixing chamber, it is mounted on a lever of elastic material, one end of which is fixed on the carburetor cover, the other is connected via a rod to a button located in the passenger compartment or under the hood of the vehicle.

 The device is installed directly on the carburetor itself in order to block the air supply channels of the primary mixing chamber. Therefore, the proposed device can be installed on any carburetor of an internal combustion engine.

 The drawing shows a General view of the device.

 The device consists of a lever 1, valve 2 and rod 3. The button is conditionally not shown.

 The production technology of the device is as follows.

 Lever 1 and valve 2 are made of spring steel and heat-resistant elastic material by stamping, respectively, the latter is firmly attached to the lever. The finished unit (the lever with the valve) together with the rod 3 made of durable flexible material is fed to the assembly line of the propulsion system, where the finished unit is installed in the air filter housing 6, mounted on the cover 4 of the carburetor. The rod 3 is attached to the free end of the lever 1. After installing the propulsion system on the transport device, the free end of the rod 3 is closed on the button installed in the passenger compartment or under the hood.

 In statics, the device is in a free state. To do this, release the tension of the rod 3 using the button and thereby, under the action of elastic forces, the free end of the lever 1 moves up to the stop with the cover 7 and at the same time the valve 2 opens the air supply channels 5 to the primary mixing chamber to start the engine.

 In dynamics, the state of the device is operational. The button through the rod 3 and the lever 1 press the valve 2 to the upper plane of the carburetor cover 4 and thus close the air supply channels 5 to the primary mixing chamber and the engine does not start.

 The difference in the proposed design of the device is the absence of elements related to the power supply of the vehicle. The proposed design of the device allows you to make and install it even for a car enthusiast.

Claims (1)

 A device for preventing the unauthorized use of a vehicle, comprising a valve blocking the air supply channels for starting the engine, characterized in that the valve is mounted on a lever of elastic material, one end of the lever is fixed to the carburetor cover, and its free end is connected by a rod to a button installed in the cabin or under the hood to ensure that when pulling the thrust, the valve closes the air supply channels to the carburetor primary mixing chamber.
