Abstract

The utility model relates to a trinity inclined-plane combined piston ring. The combined piston ring is composed of a middle ring (2), a left ring (1) and a right ring (3), wherein the left ring (1) and the right ring (3) are located in the two sides of the middle ring (2). The middle ring notches (2a) of the middle ring (2) cooperate with the left ring boss (1a) of the left ring (1). Two right ring notches (3a) of the right ring (3) are located in the two sides of the two middle ring notches (2a) of the middle ring (2). The combined piston ring can solve the tail gas pollution problems of the engine and the internal combustion engine. The trinity ring functions together with a piston to make the seal inside a cylinder enhanced. Thus the service life of the engine and the service life of the internal combustion engine can be prolonged. The lubricating oil can be prevented from entering the combustion chamber and leading to an increase in tail gas emission. Two oil rings or three oil rings can function together. In this way, not only the three-maintenance can be spared but also the fuel can be reduced and saved. The combined piston ring which has the characteristics of high efficiency and low energy consumption can significantly improve the environment. The trinity inclined-plane combined piston ring in the utility model can be applied in pistons of an engine and an internal combustion engine. The piston ring products which can have variable sizes can be manufactured into diversified models with divergent specifications. The trinity inclined-plane combined piston ring is worth widely popularizing and applying.

The model utility content

This practical purpose is will provide a kind of and the cylinder body good seal, can prolong motor or internal-combustion engine working life, smooth working, can reduce the impact force in annular groove, can guarantee the gap in the annular groove, can stop lubricant oil and enter and cause discharging tail gas to increase in the firing chamber, oil ring can two rings or three rings work together, not only can remove three from and support, and three-in-one inclined-plane multiple-piece piston-ring that can economization fuel.

The technical solution adopted in the utility model is: a kind of three-in-one inclined-plane multiple-piece piston-ring, it is characterized in that: this multiple-piece piston-ring is made of central ring and left and right sides ring, the central ring otch of central ring cooperates with the left side ring boss of left side ring, and two right side rings cut of right side ring are on the both sides of two central ring otch of central ring.

Preferably, described central ring is provided with the central ring otch, outside the radial center of central ring, be equipped with the outer shroud U-groove bevel, ring U-groove bevel in the radial center of central ring, being equipped with, form the H tee section, be evenly equipped with on the H tee section and centrosymmetric radial groove hole, the quantity in groove hole is 3-12.

Described left side is equipped with the left side rings cut, ring boss on the left of a side of left side ring is provided with.

Described right side is equipped with the right side rings cut, and a side of encircling on the right side is provided with right side ring boss.

The beneficial effects of the utility model are: owing to adopt above-mentioned structure, can solve motor, exhaust gases of internal combustion engines pollutes, three-in-one ring is worked with piston, make sealing enhancing in the cylinder body, can prolong motor, internal-combustion engine life-span, three rings can make ring smooth working in annular groove together, can reduce the impact force in annular groove, can guarantee the gap in the annular groove, can stop lubricant oil and enter and cause discharging tail gas to increase in the firing chamber, oil ring can two rings or three rings work together, not only can remove three from supports, and can economization fuel, both had the efficient height, characteristic of low energy consumption can also make environment obtain big improvement, the utility model can be used for motor, use on the internal combustion engine, product is changeable, can be made into multiple model specification, should vigorously promote the use.
