The present invention relates to a vehicle fuel lubrication gun, and more particularly, to configure a gas mouth sensing unit on a spout of a gas lubrication gun for a gasoline fuel of a vehicle to control operation of a solenoid valve on a fuel supply pipe inside a lubricator to inject gasoline fuel into a diesel vehicle. The present invention relates to a fuel supply condition for a vehicle that can be prevented in advance.

In general, the lubricator is a device for injecting oil from the oil storage tank buried underground to be driven by a fuel pump driven by a drive motor and a belt to supply oil to a vehicle through a hose.

The lubricator, as shown in Figure 1, is connected to the lubricator main body 100 including the oil intake and various mechanical devices therein, and the main body 100 and the lubrication hose 119 therein It is composed of a gas gun 123 to allow the fuel source to supply the oil sucked by the mechanical operation to the fuel tank (not shown) of the vehicle.

That is, the lubricator main body 100, as shown in FIG. 1, is provided with a lubrication pump 103 is operated by the driving force of the drive motor 101 therein to suck oil from the oil storage tank (not shown) do.

The oil pump 103 and the drive motor 101 are provided with a pulley 105 and 107 on the rotation shaft of the drive motor 101 and the rotation shaft of the fuel pump 103 to enable power transmission. ).

In addition, a flow meter 111 is installed above the fuel pump 103 to measure oil flow from the fuel pump 103, and a solenoid valve 113 is installed on the flow meter 111.

The solenoid valve 113 is installed to control the flow rate or to block the flow path, the solenoid valve 113 is connected to the flow meter 111 and the oil supply hose 119 through the fuel supply pipe 115. do.

Here, the drive motor 101 and the solenoid valve 113 is electrically connected to the controller 121 to be operated controlled by the control signal of the controller 121.

In addition, the fuel gun 123 is a gun body 125 formed so that the oil supply source can be easily grabbed, and the spout 127 is formed by protruding from the gun body 125 and the oil flowing through the fuel hose 119. It is configured to inject into the fuel tank of the vehicle.

The lower portion of the gun body 125 is provided with a lever 129 is configured to perform the opening and closing operation by the operator pull and release selection.

In addition, the refueling gun 123 has an automatic operation means for stopping the refueling state at the completion of refueling, while the refueling source continues to achieve the refueling state without continuously grabbing and pulling the lever 129 when refueling. It is provided.

This automatic operation means is installed at the tip of the spout 127 of the gun body 125 to install the air sensor unit 131 using the air to detect the surface level of the oil filled in the fuel tank of the vehicle by the fueling state The lever 129 is fixed to the one side gun body 125 of the lever 129 by pulling the lever 129 in a pulled state or by an operation according to a detection signal by the air sensor 131. The ruler 133 for releasing the latch is provided.

Therefore, at the time of refueling, when the refueling source removes the refueling gun 123 from the pocket 135 configured at the side of the oil main body 100, a motor switch (not shown) is operated to drive the driving motor 101 to supply the refueling pump 103. In this state, when the lever 129 is pulled while the spout 127 of the gas gun 123 is inserted into the fuel tank of the vehicle, the signal is output to the controller 121 and the controller ( 121 controls the solenoid valve 113 so that the flow path is opened so that the oil is made.

At this time, while the lever 129 is hanging on the ruler 133, a continuous oiling state is performed without manual operation, but when the fuel gradually rises in the fuel tank, the surface level thereof increases and the air sensor unit 131 When there is no movement of air, its signal is output to the controller.

The controller receiving the signal issues an operation command to the ruler 133 to release the latch of the lever 129, thereby stopping the automatic oiling operation.
