Description

Lubricator collecting oil vapor and its assembly method {Lubricator collecting oil vapor and its assembly method}

The present invention relates to an lubricator for collecting oil vapor and a method for assembling the lubricator, and more particularly, an lubricator for collecting oil vapor and an lubricator for collecting oil vapor so that the air moving pipe and the lubricating nozzle pipe can be easily and simply inserted into the vapor suction pipe. It is about a method.

In general, the lubricator is a device for injecting oil from the oil storage tank installed in the basement to supply oil through a hose, etc., which is an oil lubricator main body including the oil intake and various related mechanical devices therein, and the main body and It is composed of a nozzle that is connected by a hose to allow the fuel source to supply the oil sucked by the mechanical operation inside the main body to the fuel tank (not shown) of the vehicle. In addition, the main body is provided with a pump 120 that is operated by the driving force of the motor 100 as shown in Figure 1a to suck the oil from the underground oil storage tank.

The pump 120 is operated by the driving force of the motor 100 as described above, the transmission thereof is the motor pulley 110 and the pump pulley on the rotary shaft of the motor 100 and the rotary shaft of the pump 120, respectively. 130 is installed, and the belt 140 is connected therebetween to transmit the driving force of the motor 100 to the pump 120 by the belt transmission.

In addition, a flow meter 150 is installed at an upper side of the pump 120 to measure oil flowed from the pump 120, and a solenoid valve 180 is installed at an upper side of the flow meter 150. The solenoid valve 180 is installed to control the flow rate or to block the flow path, the inlet pipe 160 is connected to the flow meter 150 on one side of the solenoid valve 180, the other side The discharge pipe 170 is connected to the hose 200.

In addition, the lubricator 300 is a fuel nozzle 320 is formed so as to protrude in a spout form from the nozzle body 310 formed so that the oil supply source can be easily held by hand as shown in Figure 1b to the hose 200 It is configured to discharge the oil flowing into the nozzle body 310 through the outside, the lower side of the nozzle body 310 is provided with a lever 330 by the pull and release of the fuel supply source of the solenoid valve ( It is configured to perform the opening and closing operation of the flow path by 180). In addition, the lubricator 300 has an automatic operation means for stopping the lubricating stroke at the completion of lubrication while allowing the refueling source to continue to be made without continually holding and pulling the lever 330 when refueling It is provided.

The automatic operation means to install a sensor 340 at the end of the fuel nozzle 320 of the nozzle body 310 to detect the oil level of the oil filled in the fuel tank (T) of the vehicle by the refueling stroke, On one side of the nozzle body 310 of the lever 330 to lock the lever 330 in a pulled state or to release the latch of the lever 330 by the operation according to the detection signal by the sensor 340. Gwaehaego 350 is provided.

The lubricator configured as described above opens the flow path by the solenoid valve 180 by pulling the lever 330 in a state in which the lubrication nozzle 320 of the lubricator 300 is first inserted into the fuel tank T of the vehicle. At the same time, the motor 100 is driven by an operation command by a controller (not shown). Accordingly, the motor pulley 110 installed on the rotation shaft of the motor 100 rotates, and the rotational force of the motor pulley 110 is transmitted to the pump pulley 130 again by the belt 140 transmission to pump 120. Will be activated. As the pump 120 is operated as described above, the oil in the underground oil storage tank is sucked into the pump 120, and the sucked oil is metered through the flow meter 150 at the pump 120 while the solenoid valve 180 is operated. Flows into the inlet pipe 160. In addition, the oil flowing into the inlet pipe 160 is supplied to the nozzle body 310 through the solenoid valve 180 again through the discharge pipe 170 and the hose 200, and is supplied to the nozzle body 310. The discharged oil is discharged through the oil supply nozzle 320 of the nozzle body 310 to perform the oil supply stroke.

At this time, the fuel supply source performs continuous refueling operation without manual operation in the state of hanging the lever 330 on the rubbing. In this state, when the oil level in the fuel tank T of the vehicle continues to rise to reach the sensor 340 installed at the end of the fuel nozzle 320 of the lubricator 300, the sensor 340 is a signal thereof The controller is sent to the controller, the controller receives the signal to give the operation command to the ruler / solver 350 to release the latch of the lever 330. Accordingly, as the flow path by the solenoid valve 180 is blocked, the operation of the related devices is stopped and the series of oil supply strokes is automatically stopped.

The conventional lubricator operating as described above can be divided into two types according to the fuel used, because it is divided into a diesel vehicle using diesel as fuel and a gasoline vehicle using gasoline as fuel.

In general, the fuel inlet of the diesel vehicle is made larger than the fuel inlet of the gasoline vehicle, so the oil tanker of the diesel vehicle cannot enter the fuel inlet of the gasoline vehicle, but on the contrary, the gasoline of the gasoline vehicle can enter the fuel inlet of the diesel vehicle. In addition, even gasoline vehicles may be made larger than gasoline ports of vehicles using ordinary gasoline as fuel. (See Tiko Oil Zone.) In addition, in the case of jeep cars, gasoline vehicles and diesel vehicles are used in combination.

According to the type of the vehicle as described above, the appropriate gasoline is used, there is a problem that the gasoline filling machine is plugged into the diesel vehicle in which the fuel inlet is largely formed by mistake of the gas source, and sometimes the fuel is thrown away and the injected fuel is discarded. After dismantling, there is not only the troublesome task of cleaning and drying the interior and removing other fuel transferred to the fuel line of the vehicle, but also causing damage to the internal combustion engine in severe cases.

Another problem is that the fuel is drained from the fuel inlet and the fuel is sprinkled on the floor when the fuel is pumped out at the same time due to the lack of one hand while setting the fueling amount of the customer. In addition, there was a problem of causing a large fire by static electricity.

In order to solve the above problem, the present applicant has been registered with the Patent No. 451972, but the Patent No. 451972 has only the anti-mixing function but no vapor collection function.

On the other hand, when refueling, as shown in FIG. 2A, conventionally, when refueling a vehicle, an oil supply of a general gas tanker 300 is introduced into an oil filling hole formed in a fuel tank T of an automobile, thereby injecting oil. In many cases, gasoline or diesel oil from the fueling process leaked into the gap between the car's filling port and the oil drainage pipe of the tanker.

Not only are the driver or petrol station feeling uncomfortable by this vapor, but when the evaporation gas stays around the gas station, there is a high risk of a large explosion accident or fire if it is ignited by a cigarette or small ember.

In view of such a conventional problem, a vapor inhalation apparatus for collecting oil vapor has been proposed. The conventional vapor inhalation apparatus is shown in FIG. 2B, as shown in FIG. 2B, a conventional vapor inhalation apparatus is connected to a main body 310 by a hose. In the conventional oil tanker 300 is connected to the fuel injection nozzle 320 protruding forward to inject the oil into the fuel tank of the vehicle to inject oil into the fuel tank (T) of the vehicle, it extends toward the front around the fuel nozzle 320 To form a plurality of intake holes 410 around the flexible sealing membrane 400 having an open front surface, and to attach and detach one side of the intake pipe 500 to the rear of the flexible sealing membrane 400.

Mixing prevention means 40 is provided to be movable while pressing the spring 30 is installed on the outer circumferential surface of the vapor suction pipe 50, the mixing prevention means 40 is used in the form of a ring. The mixing prevention means 40 is a guide hole 53 integrally formed with a moving hole 51 formed to penetrate the outer circumferential surface of the oil vapor suction pipe 50 and a stop hole 52 provided to temporarily stop at the end of the moving hole 51. Is moved along.

On the other hand, the outer circumferential surface of the vapor suction pipe 50 has a structure formed of a vapor suction pipe 50 formed with a plurality of permeable vapor suction holes 54 and the stepped portion 55 formed at a predetermined distance from the end.

On the other hand, the gap 60 formed between the oil vapor suction pipe 50 and the fuel nozzle pipe 20 is the guide mixture (53) when the oil mixture is started by detecting the air by the mixing sensor means 40 is activated by the sensor ) And the vapor suction hole 54 is connected to the vapor suction means 70 for forcibly suctioning the vapor into the gap 60 connected thereto.

In the oil vapor suction pipe 50 in which the oil injection nozzle pipe 20 is installed, a flexible sealing membrane 80 is installed to close the fuel injection hole when the fuel injection hole is inserted into the fuel injection hole. The oil injection nozzle 50 is provided at an end of the oil vapor suction pipe 50. Bushing 90 is configured to hold the tube 20 and the air moving tube 10 so as not to flow.

The guide piece 96b may be used by providing a U-shaped guide bracket 96 formed integrally with the connecting portion 96a.

Accompanying drawings Figure 11 is an exemplary view showing another coupling method of the lubricator to which the technique of the present invention is applied to the coupling head portion 50a and the nozzle insertion tube portion 50b for coupling the oil vapor suction pipe 50 to the lubricator main body 50 It is formed to change the structure so that the coupling head portion 50a and the nozzle insert pipe portion 50b is screwed to separate the coupling head portion 50a, and then the oil supply nozzle tube 20 and the air moving tube 10 to the vapor suction tube. When inserted into the nozzle insert pipe portion 50b constituting the 50, the oil nozzle pipe 20 and the oil injection pipe pipe 50 to the oil vapor suction pipe 50 more easily than when the coupling head portion 50a and the nozzle insert pipe portion 50b are combined. The air moving tube 10 can be inserted into the installation.

The reason is that when the coupling head portion 50a and the nozzle insertion tube portion 50b are coupled to each other at a predetermined angle, the oil injection nozzle tube 20 and the air moving tube 10 are inserted into the oil vapor suction tube 50. Although it is not easy, the oil injection nozzle pipe 20 and the air moving tube are first inserted into the nozzle insertion pipe part 50b in which the bushing 90 is inserted while the coupling head part 50a and the nozzle insertion pipe part 50b are separated. The assembly method as described above by coupling the coupling head portion (50a) from the back after installing (10) has the advantage that it is easy and simple to combine the fuel nozzle pipe 20 and the air moving pipe 10 with the bushing 90, but One joining process, that is, one screw joining the joining head part and the nozzle insert pipe part is increased.

The method of assembling the lubricator to which the technique of the present invention is applied as described above forms an oil nozzle tube insertion hole 91 and an air movement tube insertion hole 92 into which the oil nozzle tube 20 and the air movement tube 10 are fitted, but the air movement tube In communication with the insertion hole (92) and the center coincides with the air suction hole (55) formed a plurality of vapor suction holes that can suck the vapor in the bushing (90) formed a suction through-hole (93) for passing the air After installation on the oil vapor suction pipe (50), the oil injection nozzle pipe (20) and the air moving pipe (10) to the oil injection pipe pipe insertion hole (91) and the air moving pipe insertion hole (92) from the opposite side where the bushing (90) is installed. ) Is inserted into the bushing 50 when the insertion pipe alignment means is inserted into the through-hole 52 to be assembled while preventing the flow of the fuel nozzle pipe 20 and the air moving tube (10).
