Description

Oil supply nozzle with oil type oiling prevention function {Oil supplying nozzle}

The present invention relates to a refueling nozzle having a function of discriminating oil type of fuel oil based on a vapor concentration in a fuel tank of an automobile.

The fuel oil of a vehicle includes light oil and gasoline. If fuel is supplied incorrectly, engine failure may occur. For this reason, the present applicant has provided a vapor pump in the nozzle body to operate the vapor pump by moving the valve opening lever, leading the vapor in the fuel tank of the vehicle to the vapor sensor, and detecting the detection signal from the vapor sensor. It has been proposed to supply fuel oil by driving the oil supply pump if the oil type is discriminated in the oil supply unit receiving this detection signal by outputting it to the oil supply unit.

However, according to the above method, even if a vapor sensor and a vapor pump are provided in the oil supply nozzle, it is necessary to output the detection signal from the vapor sensor to the oil supply device.

Therefore, it is necessary to wire the signal line between the oil supply nozzle and the oil supply device.

In addition, there is a time lag between pulling the valve opening lever and feeding fuel oil based on the detection signal. In addition, the function of detecting the vapor is provided in the oil supply nozzle, and the function of performing oil supply control by the detection signal is provided in the oil supply device. Therefore, the installation of signal lines and controllers is a great burden for the existing oil supply device. There is also a problem that cannot be added due to this much-consuming problem.

The present invention has been made in view of the above problems, and its object is to provide a lubricating nozzle with a lubrication oil lubrication prevention function that can be added to an existing lubrication device simply by preventing erroneous oil lubrication as a nozzle unit. There is.

In order to solve such a problem, in the present invention, the main valve for opening and closing the flow path; In the oil supply nozzle having a valve lever for opening and closing the main valve, the valve opening regulation means of the main valve, oil type detection means for detecting the oil type in the oil supply tank, oil type storage means for storing the oil type to be supplied, oil kind detection means If the detected oil type and oil type stored in the oil kind storage means coincide with each other, a control means for releasing the regulation of the valve opening regulating means is provided. Therefore, it is impossible to refuel even if it is inserted into a fuel tank other than the oil type stored in the oil supply nozzle in advance. Misfeeding can be prevented. In addition, based on the oil type judgment and the result, the opening and closing regulation of the main valve is carried out in a single nozzle unit. Therefore, the oil supply can be prevented by simply replacing the oil supply nozzle with an existing oil supply device, thereby realizing a low cost function.

In addition, it is possible to know immediately that the oil kind is wrong because the oil kind detected by the oil kind detection means and the oil kind stored in the oil kind memory means are prepared to operate when there is a mismatch.

As shown in FIG.

As shown in FIG. 2, the oil supply nozzle 5 is comprised as the nozzle main body 21, the discharge pipe 22, and the handle part 23, One end to the discharge pipe 22 near the tip of the discharge pipe 22. As shown in FIG. An air pipe 24 having an inlet 24a is inserted, and the other end is connected to an automatic valve closing mechanism (not shown) of a conventionally known structure. One end of the vapor pipe 25 is inserted into the discharge pipe 22 so as to have an open portion 25a near the distal end of the discharge pipe 22, and the other end of the vapor pipe 25 is connected to the oil kind detecting means 26 described later. It is connected. The nozzle body 21 has a valve opening lever 29 for opening and closing the main valve 28 provided in the flow path 27 formed therein, and oil kind detection means for detecting oil type through a vapor introduced from the vapor pipe 25. (26) is provided.

The oil kind detecting means 26 is provided at the upper side of the nozzle body 21, and is connected to one end of the vapor pipe 25 to detect the concentration of the vapor when the vapor coming up from the fuel tank of the vehicle arrives. A sensor chamber 31 containing the sensor chamber, one end of which is connected to the sensor chamber 31, a vapor pump 32 for suction cleaning the vapor, and a switch 33 for turning the vapor pump 32 on and off. In addition, in the nozzle body 21, the valve opening lever 29 is supported by the shaft 35 which protrudes from the solenoid 34 at ordinary times, and the rotation operation is prevented, but the main valve 28 is opened to supply oil. At the time of carrying out, the valve opening regulating means for exciting the solenoid 34 and pulling the shaft 35 to move the valve opening lever 29 in the opening direction (that is, to the rear side provided with the solenoid 34) ( 36) and fuel and oil supply nozzles in vehicle fuel tanks (2006.01) And a notifier 37 for notifying that the oil type is incorrectly selected when the fuel to be supplied from the fuel oil is detected different from each other by the oil kind detecting means 26, and the valve opening controlling means 26 connected to each of these devices. It is comprised as the control apparatus 38 which performs control to the notifier 37 grade | etc.,. In the drawing, reference numeral 39 denotes a battery for driving the device, and reference numeral 40 denotes a stopper which prevents the valve opening lever 29 from pressing the switch 33 when the valve opening lever 29 is opened.

As shown in Fig. 3, the control device 38 receives the output from the switch 33 and receives the output of the forward rotation signal or the end of the oil classification determination from the determination means 41, and outputs the reverse rotation signal for a predetermined time. (42), a pump driving means (43) for forward or reverse rotation of the vapor pump (32) by the output from the time-measuring means (42), a oil type memory means (44) for storing oiled oil, and judgment The solenoid drive means 45 which receives the output of the oil kind coincidence signal from the means 41, and excites the solenoid 34, and operates the notifier 37 by receiving the output of the oil kind mismatch signal from the determination means 41. It is comprised as the notification driving means 46. As shown in FIG.

Next, the operation will be described. When the oil supply nozzle 5 is removed from the nozzle hanger 7, a drive signal is output from the nozzle switch 8, and the oil supply pump 4 is driven. Then, when the discharge pipe 22 of the oil supply nozzle 5 is inserted into the oil supply port provided in the vehicle and the switch 33 is pressed, the drive signal from the switch 33 is output to the control device 38.

In response to this signal, the control device 38 outputs the forward rotation signal from the time-measuring means 42 to the pump drive means 43 for a predetermined time, for example, 5 seconds, and as a drive signal from the pump drive means 43. The vapor pump 32 is rotated forward, and the vapor in the fuel tank is sucked into the sensor chamber 31 through the vapor pipe 25 from one of the openings 25a provided at one end near the front end of the discharge pipe 22. The concentration detection value detected from the vapor sucked into the sensor chamber 31 is outputted to the control device 38, and the determination means 41 compares the oil kind and the concentration detection value stored in the oil kind storage means 44.

When the oil type and the concentration detection value coincide with each other, the control device 38 outputs a drive signal to the solenoid driving means 45. Upon receiving this, the solenoid driving means 45 excites the solenoid 34, immerses the shaft 35, and releases the support state of the valve opening lever 29, thereby pulling the index finger to move the valve opening lever 29 to the rear side (solenoid). Side), and the main valve 28 is opened in conjunction with the movement of the valve opening lever 29, whereby the fuel oil supply nozzle 5 can supply fuel oil. If the oil type and concentration detection value of the fuel tank and the fuel supply nozzle do not coincide with each other, the control unit 38 does not output the solenoid driving signal, and the solenoid 34 is not excited. The valve opening lever 29 cannot be pulled by maintaining the state of protruding toward the opening lever 29 and preventing the valve opening lever 29 from rotating. In addition to being impossible, the drive signal is output to the notifier driving means 46 to operate the notifier 37 to inform that the oil types are different.

As described in detail above, the oil supply nozzle with the misclassification oil supply prevention function according to the present invention includes a valve opening regulating means of the main valve in the oil supply nozzle having a main valve for opening and closing the flow path, a valve opening lever for opening and closing the main valve, and If the oil kind detection means for detecting oil type in the oil supply tank, the oil kind memory means for storing the oil kind being oiled, and the oil kind detected in the oil kind detection means and the oil kind stored in the oil kind storage means are matched, the valve opening restriction means is deregulated. Since the control means is provided, it is impossible to refuel even if it is inserted into a fuel tank other than the oil type stored in the oil supply nozzle in advance, thereby automatically preventing misfeeding of other types of oil.

Moreover, based on oil type judgment and result, the opening and closing regulation of the main valve is carried out by a single oil supply nozzle, so that only the oil supply nozzle can be easily replaced with an existing oil supply device, and the function can be added at low cost. In addition, it is possible to immediately know that the oil type is different because a notification device that operates when the oil kind detected by the oil kind detecting means and the oil type stored in the oil kind memory means is inconsistent.
