Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an oiling pump for an oil combustion device.

[Conventional technology]

Conventionally, this type of lubrication pump has only lubrication means for lubricating kerosene, and the lubrication cap was opened by hand and the lubrication hose was inserted into the tank for lubrication.

[Problems to be solved by the invention]

In the conventional lubrication pump for oil burning equipment as described above, it takes time and effort to open the refueling cap during lubrication.
Particularly, in the case of a cartridge tank, there is a problem that kerosene is attached to the refueling cap and the hand is soiled when opening the refueling cap.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide an oiling device for an oil combustion apparatus without opening the refueling cap by hand and without soiling the hand. It is a thing.

[Means for Solving Problems] In order to achieve the above-mentioned object, an oil-fueling device for an oil-burning device of the present invention comprises a holder body on the discharge side of the oil-fueling device attached to an oil-filling cap of a cartridge tank and the cartridge In an oil-filling device for oil-burning equipment that fills tanks, the holder body is always closed on the discharge side of the oil-filling device, and an oil-filling valve that opens when the holder body is attached to the oil-filling cap is provided. The cap is provided with an oil supply port which is always closed and an oil supply valve which is opened when the holder body is attached to the oil supply cap.

[Action]

According to the present invention, an oil pump for an oil burning device is provided with a function that does not open the refueling cap by hand and does not soil the hand.

〔Example〕

 An embodiment will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a cross-sectional view of a holder body of an oiling device of the present invention, and FIG. 2 is a cross-sectional view of a holder body and an oil supply cap fitted to each other so that oil can be actually injected.

In the figure, reference numeral 1 denotes a cartridge tank (hereinafter simply referred to as tank 1) of an oil burning device, and a refueling cap 2 is detachably provided at an appropriate position on one end of the tank 1. Reference numeral 3 denotes an airtight packing which is provided at a predetermined position in order to maintain the airtightness of the refueling cap 2 fixed to the tank 1.
The refueling cap 2 is attached to the opening screw portion 1a on the tank 1 side.
When the screw portion 2a is fitted and tightened, the airtight packing 3 brings the tank 1 and the oil supply cap 2 into a completely airtight state.

Reference numeral 4 denotes a holder main body on the discharge side of an oiling device for injecting kerosene from a storage tank into the tank 1. An oil supply pipe 5 is provided in the center of a lower portion of the holder main body 4 and a circumferential portion of a cap 4a of the holder main body 4. The exhaust ports 6 are provided respectively. 7
Is a lubrication valve 7 provided inside the holder body 4, and is arranged so as to be slidable up and down by an lubrication valve spring 8 provided at an upper portion inside the holder body 4. Further, a ring 9a is provided on the outer end portion of the oil injection valve 7. That is, when oil is not injected, the oil injection valve 7 is moved by the oil injection valve spring 8
Is urged toward the oil supply port 10 provided on the ring 9a.
As a result, the oil feed port 10 of the oil feed pipe 5 is completely shut off. Reference numeral 11 denotes a valve seat holder mounted inside the refueling cap 2. Inside the valve seat holder 11, a refueling valve 12 is slidable up and down by a refueling valve spring 13 provided on the tank 1 side of the valve seat holder 11. It is arranged.

Reference numeral 14 denotes an oil supply port provided on the upper part of the oil supply cap 2 so that the oil supply pipe 5 of the holder body 4 can be inserted and removed freely.

Further, when the oil supply pipe 5 is inserted into the oil supply port 14, the tip of the oil supply valve 7 comes into contact with the outer portion of the oil supply valve 12,
A ring 9b is provided. That is, when oil is not injected, the oil supply valve 12 is biased by the oil supply valve spring 13 toward the oil supply port 14 and the ring 9b completely shuts off the oil supply port 14 of the oil supply cap 2.

When the holder main body 4 is pushed into the refueling cap 2 side when trying to refuel, first, the tip of the refueling valve 7 contacts the refueling valve 12, and the refueling valve spring 8 is set to be weaker than the refueling valve spring 13. Therefore, the lubrication valve 7 opens. When the oil supply valve spring 8 is slightly contracted, the oil supply valve 12 is opened next, and the open state is established. Kerosene, which serves as fuel, flows from the tip of the oil feed pipe 5 through the valve seat holder 11, which has a space on most of its side surfaces, and flows into the tank 1 for oil injection. Further, since the same volume of air as the volume of kerosene that has been injected is released, the refueling port 14 forms a space that is not blocked. Reference numeral 15 is a lock spring, 16 is a spring groove provided on the inner circumference of the cap 4a of the holder body 4, 17 is a lock groove provided on the outer circumference of the oil supply cap 2, and the lock spring 15 is the spring groove 1
It is attended to 6. Therefore, when the holder body 4 is pushed into the refueling cap 2, the tapered portion 2b of the refueling cap 2 is pressed.
As a result, the lock spring 15 fits into the lock groove 17. Here, the lock spring 15 and the lock groove 17
The spring groove 16 and the spring groove 16 are restrained together to form restraint means.

The operation of the lubricating device of this embodiment configured as described above will be described below.

FIG. 3 is a sectional view showing the shape of the spilled kerosene at the time of kerosene lubrication. In the figure, 18 is an oil feed passage provided in the holder main body 4. When kerosene is sent from the oil feed passage 18 in the direction of the arrow, the kerosene is discharged from the oil feed pipe 5 into the refueling cap 2 and into the tank 1. Lubricated. At this time, the same volume of air as the volume of the kerosene that has been injected passes through the oil supply port 14 and escapes from the exhaust port 6 of the holder body 4. At this time, the oil supply pipe 5 is sufficiently inserted into the oil supply port 14 so that the injected kerosene does not enter the tank and overflows outside.
The exhaust port 6 is also provided so that there is no resistance.

When the lock spring 15 is released from the restraint during the lubrication or after the lubrication is completed as described above, the holder body 4 is separated from the lubrication cap 2, the lubrication valve 7 is closed by the lubrication valve spring 8, and the ring 9a is used to feed the oil. The oil port 10 is completely shut off. Therefore, no matter how much kerosene is sent to the oil feed passage 18 in this state, the kerosene does not come out of the holder body 4. Further, the oil feed pipe 5 is provided with a guide hole 5a at the center thereof so that the tip of the oil feed valve 7 is not distorted.

[Effect of device]

Since the lubricating device for the oil burning equipment of the present invention is configured as described above, it is possible to lubricate the fuel into the cartridge tank without opening the refueling cap by hand and without polluting the hands, and further refueling the holder body. Even if the lubricator is accidentally activated before mounting on the cap, or if the holder body accidentally comes off the lubrication cap during lubrication, the discharge side of the lubricator is closed by the lubrication valve on the holder body. Since the fuel does not spill outside, it is possible to reliably prevent the fuel from spilling outside due to an erroneous operation during lubrication.
