Description

Choke Cable Tensioning Device for LP Vehicles

The present invention relates to a tension control device of a choke cable used in LP vehicles, in particular, to enable a smooth operation with a small force to improve the convenience of the driver.

In general, the vehicle generates power by using the expansion force generated by mixing the fuel source with air and diluting it, and then sucking and compressing it into the cylinder, and igniting. It is used as a moving means.

According to the fuel sucked into the cylinder of the engine, it is divided into gasoline engine using gasoline, diesel engine using diesel oil and LP engine using gas, and the LP gas car uses its fuel source as gas. As shown in FIG. 2, the gas discharged in the liquid state from the tank 100 passes through the filter 110 and enters into the regulator or regulator 130 through the solenoid valve 120 while the substance is caught. .

After passing through the regulator 130, the gas is reduced pressure and then mixed with the air sucked in the gas mixer 140, and then flows into the cylinder to generate power and discharge into the atmosphere through the process of compression, ignition, and exhaust. Repeat the action to get the power needed to drive.

The solenoid valve 120 is installed in the high pressure fuel pipe, and serves to stop the fuel when the engine is stopped in order to ensure safety.

At this time, the regulator 130 used to pressurize the gas has a negative pressure type and a pressurized type according to the pressure of the gas outlet, and there are many negative pressure equations which are reduced in two stages in the regulator and are converted to a state almost equal to the atmospheric pressure of the pressure in the gas mixer. It is used.

This regulator is the most important part of gas equipment, and it has three functions of decompression, vaporization, and pressure control. LP gas decompressed in the primary decompression chamber and primary decompression chamber which vaporizes and simultaneously decompresses the LP gas of the pressurized liquid. It is composed of a secondary pressure reducing chamber to control the pressure by reducing the pressure to near atmospheric pressure again.

The secondary pressure reducing chamber is connected to the mixer to reduce the LP gas to near atmospheric pressure, and there is a valve and an adjustment spring inside the engine, and the engine automatically closes the valve so that fuel does not flow out on time. A vacuum lock of chamber is provided.

The vacuum lock of chamber is partitioned by a secondary pressure reducing chamber and a diaphragm and is passed through an intake manifold.

Therefore, since the negative pressure is not introduced into the chamber when the engine is stopped, one end of the secondary valve lever is pressed by the force of the vacuum lock of spring to automatically close the secondary valve.

The left chamber of the secondary decompression chamber is in communication with the atmosphere, and the fuel test bar is located in the room, and when the engine fails to start, the fuel test bar is manually operated to force the secondary valve to open.

This causes the secondary valve to be forcibly opened by pulling the start lever provided in the driver's seat to operate the link device. The vaporized LP gas is sent to the gas mixer and mixed with air to generate power by generating power. Let's go.

At this time, the starting lever used to fix the choke cable 100 is connected to the end of the link (not shown) provided to operate the secondary valve of the vaporizer 130 as shown in FIG. It is provided with a guide shaft 110, but to form a screw portion 112 at the end of the guide shaft 110 to fix the knob 120.

In addition, a plurality of fixing grooves 114a, 114b, 114c are formed on the bottom surface of the guide shaft 110 to adjust the amount of movement of the guide shaft 110, and the stopper 130 is inserted into the groove to fix the movement amount of the guide shaft 110. do.

The stopper 130 is composed of a movable member 136 inserted into the groove and a ball 134 therein to be fixed to one side of the instrument panel.

When the start lever configured as described above pulls the knob 120 protruding from one side of the instrument panel at the beginning of the hand, the guide shaft 110 connected thereto is protruded to the outside of the panel to fix the choke cable ( 100).

The choke cable 100 is pulled to operate the link connected to the end to open the secondary valve provided on the inside of the vaporizer 130, while introducing the gas vaporized LP gas into the gas mixer 140, The engine is started by being sucked into the cylinder of the engine in a mixed state.

At this time, the end of the movable member 136 is inserted into the fixing grooves 114a, 114b, 114c, which are integrally formed on the bottom surface of the guide shaft 110 while protruding outward, thereby maintaining a constant tension. When it is fixed and started, when the knob 120 is pushed in the direction of the instrument panel, the secondary valve is closed in a minimum state.

However, the lever used in the early stage of starting has a problem that the driver is forced to open the secondary valve configured inside the vaporizer by using the force to pull the knob by hand. When fixed to any position by the stopper, there is a problem that the fixed position is changed due to wear.

Therefore, the present invention has been made in order to solve the above problems of the LP car choke cable to enable the smooth operation with a small force at the time of starting the vehicle and to prevent the fixing position is changed. To provide a tension control device.
