Abstract

PURPOSE:To maintain a piston ring clean and avoid extraordinary abrasion of the piston ring and a piston liner by introducing high pressure gas together with lubricating oil into an annular pocket portion which is formed between the top ring of a piston and a second ring when the piston is at the top dead center. CONSTITUTION:An annular pocked portion 5 into which a piston ring is not fitted is provided between the top ring 3 of a piston 2 and a second ring 4. And a high pressure supplying device 6 is arranged in a culindr liner 1 at a position corresponding to the pocket portion 5 when the piston 2 is at its top dead center. In the high pressure supplying device 6, high pressure gas into which lubricating oil is sprayed is supplied through a high pressure cylinder 8 and lubricating spray device 16, and said high pressure supplying device is controlled by a valve switching control device 10 in such a way that it opens when the top ring 3 passes an introduction hole 7 by going up and it closes when the ring passes said hole by going down.

Description

DETAILED DESCRIPTION OF THE INVENTION Kikanmei is related to the sole * direct of Uchisunen 1 Binkan.

In recent years, there have been many low-priced hard particles mixed into the fuel oil used in Ifil-1 diesel engines. When such fuel oil burns inside the ring, high-temperature combustion gas containing these particles and combustion materials enters the piston ring and cylinder liner illumination, causing wear and tear. Therefore, it is necessary to reduce the weight by 61'q as soon as possible.

In Sekimae, the cylinder liner and the piston ring have 11 slippages, and the crank has a 12+ jump in water.
Do no harm. In addition, the inner periphery of the cylinder liner 1nl K Junichi (the hole that connects the mountain) is 1 year old, and the decoy music is supplied by the pump on a one-time system. When doing this, the lubrication near the top ring of the piston and the piston ringage j of 2+G1-1 is insufficient.Also, as mentioned above,
+lll supply hole is provided between the inner periphery of the cylinder liner and it is 11 if 1-η1 is drilled as if it were a tree. In the meantime, there is h14.

The pressure in the ring is even higher than the one above.

l! The gist of this is to completely prevent the intrusion of unburned items into IIIJ songs, and to reduce the volume of I/RII with 5VC.

Attach “Book A13” 1. ．． To explain the embodiment shown in 4' lfU, in Fig. 741, 1 is a cylinder liner, 2 is a piston, 3 is a dog ring, and 4 is a second piston ring. Top ring 3 of piston 2
and 2-d+1, an annular pocket 5 into which no piston ring is fitted is provided at the same time as the piston ring 4 of 2-d+1. The size of Pocket City 5 is 1 or more than 1 piston ring. The cylinder liner is provided with a high-pressure air supply device 6 and a four-hole hole 7 for supplying high-pressure gas from the outside to the cylinder, for example, 1 ku3 of air. . In addition, a high pressure air supply table +d 6 and one humid hole 7 or one temporary hole shall be provided. 1- Pressure Kiden 4
The high-pressure crossover supplied to the stand device 6 is made of a high-pressure gas compressor 9 and stored in a high-pressure cylinder 8. 10 is a valve opening/closing; IIIJ control device. Reference numeral 13 denotes a cooling device H. If cooled fresh air is introduced through the air intake hole 7, the temperature Vt of the piston ring will be significantly lowered, and the lubrication conditions will be significantly improved.
The same reliability can be achieved.

Next, the operation of the present invention will be described. First, the valve opening/closing control device a10 is set to the crankshaft so that when the top ring 3 passes the fourth hole 7 during the piston lift stroke, the same +14VC counterpressure stem air is supplied to the crankshaft, and the +1- ii Pressure air supply system bm 6 ('ilJ Pressure air enters the socket 5Q and 771 [:). During the downward stroke of the piston 20, the top ring 3 is

is closed, and high pressure (boxo of air) ii++ f to 5
11L Stop people. That is, the piston 2 is in the upper position, and the top ring 3 is approaching the dead center by one inch.
When +liJ is removed from the 7-person hole 7, the pressure supply device 6 becomes 2 uJJ L, and the point ljl≦5V becomes VC. Noritosano: - The 70th place I is on the 1st floor, slightly above the 216th piston ring 4. The maximum blood pressure of high-pressure mobilization should be slightly higher than the maximum pressure within the Schilling. Since the gas leakage from the top ring 3 and the 26th piston ring 4 is always small, the pressure P in the pocket 5 is 200 m as shown in Figure 2. expensive.

Therefore, pocket QJ reward 5 nv / conflict air or top ring 3) River is M 13 in the cylinder! : To 11, it is possible to prevent the combustion gas from cylinder RΔ from reaching 11 to reach the piston top run F12. Piston ring difference 'it3', d A+'

In the fishing line 15, a lubricant amount of jet 11r is applied. This 1 m 16 of water is generated by the compressed air from the straight 6 of the 4-side R straight 6, and is supplied to the air inlet hole 7 V from the passage 15. .

1q "1 ha 1 diagram. There is a communication hole 2 in the middle of Niigang 15.
Case 22 is connected through Case 1. Lubricating oil 23 is retained within this case 22. The upper end 25 of the face body 24, which has been soaked in the lubricating oil 23 to compensate for the lower end noise, is open toward the downstream side (direction in FIG. 5) of the compressed air flow force circuit 26. The throat capital 2 is caused by the radial internal force generated near the open end of the upper end 25 of the tube 24.
8 is formed. In this way, when compressed or flown into the public road 15, the pressure becomes low at the throat portion 28. As a result, the lubricating oil 23 is sucked into the tube body 24 in seven directions, and the lubricating oil 23 becomes mist-like. This mist-like lubricant mountain passes through the pipe line 15 to the introduction hole 7.
The value is ejected into the pocket part 5 from there. This ensures that the top ring 3 and the second piston ring 4 are lubricated with the second ring retainer 1.

By introducing more air than the pressure inside the cylinder into the pocket part 5, the top ring 3 and the ring groove 31
It extends from the lower inner part 31a and touches the upper part 31b. The load of the top ring 3 compensated for on the upper surface 31b in this way is smaller than that of the piston ring 4 of the second inspection. On the other hand, the second piston ring 4 is in contact with the lower inner groove 32a of the ring groove 32, and is screened from the upper inner groove 32b. It is difficult for the lubricating oil caused by splashing to rise from the piston ring 4 to the pocket portion 5 side after the second night. Therefore, it becomes difficult to lubricate the top ring 3. In this embodiment, the top ring 3 is lubricated easily because the lubricating oil is poured into the high-pressure air in a spiral shape.

In the high pressure air supply device 6, the valve field 34 is twisted by the city power,
Alternatively, it is driven by flow resistance. The lubrication of this pressure release device 6 is also carried out by the sensitized lubricant from the lubricant spray generator 16.

Therefore, the life of the high-pressure air supply device 6 can be extended.

The lubricating oil from the lubricating oil spray generator 16 is always static, and therefore good lubrication is possible.

The upper end 25 of the body 24 is open to a first section of the pressure tank air flow capacity 26. Therefore, when the air is continuously compressed, the lubricating oil 23 is not atomized. It's a good place.

Since only a small amount of lubricating oil enters the wind-burning chamber 11 from 5 yen in the pocket, the amount of lubrication is reduced.

The present invention has a castle-shaped boksotoura on the top ring of the piston and the second piston ring as well as on the entire circumference of the piston, so that it can be fired in a perfect manner. The highest pressure inside Ninrinoda guides the destruction of the mound and keeps the piston ring clean, and prevents abnormal wear of the piston ring and biston liner due to the dust particles that are soaked in the inner circle of the burning material. I'm going to smoke it out and publish it as a child. It is important to keep in mind the consumption of lubrication and ensure reliable lubrication.
