Abstract

The utility model relates to a novel piston with pattern and overlapping rings, which is composed of a tank body, a compression ring A, and an oil ring. The first layer of compression ring point on the upper part is additionally provided with one compression ring B, and two ring openings use alternative arrangement. The skirt parts on both sides of the pin hole of the tank body are provided with a plurality of heat radiation holes having definite inclination angle with the axial direction. The piston of the utility model has the advantages of saving fuel economy and motor oil, reducing material loss, reducing the temperature of the motor oil, reducing the discharge of exhaust gas, correspondingly increasing the pressure ratio of a cylinder, improving engine power, prolonging the service life of a cylinder sleeve, the piston, corresponding crankshafts, connecting rods, the shafts of convex wheels.

Description

Logical spending folded the ring novel piston

The utility model relates to a kind of piston of fuel engine, specifically refer to a kind of have capable of saving fuel, reduce spillage of material and increase the service life logically spend folded ring novel piston.

Existing engine piston, its structure generally is and is provided with twice compression ring and one oil ring on cylindrical shell, only there is a pair of pin-and-hole in its cylindrical shell skirt section, the piston of this structure exists piston and cylinder sleeve insufficient lubrication, heat radiation is slow, expansivity is big, working life is deficiency such as weak point and unstable product quality, in use cause scuffing of cylinder bore easily, the phenomenon of locking piston and piston ring, in use for some time simultaneously, because component wear, begin obviously to bleed mixed gas, high heat and waste gas, make the crankcase inner engine oil rotten, and accelerator link bent axle, the wearing and tearing of distribution device cause burn oil simultaneously, the discharging black smoke, problems such as oil consumption increase.

The purpose of this utility model just is to provide a kind of logical folded ring novel piston of spending, to pass through its structural improvement, make its advantage that has fuel saving and machine oil, minimizing spillage of material, reduces temperature, reduces exhaust gas discharging and increase the service life, thereby overcome the deficiencies in the prior art effectively.

The purpose of this utility model realizes in the following manner: a kind of logical folded ring novel piston of spending, mainly form by cylindrical shell, compression ring A, oil ring, it is characterized in that top compression ring A place at an upper portion thereof, set up compression ring B one, the collar extensions of two rings are taked to be staggered, and have some and the radiation hole that axially has certain inclination angle in the skirt section of cylindrical shell pin-and-hole both sides.

Adopt the logical folded ring novel piston of spending of the present utility model, because prior art is carried out rationally and effectively improving, make it have fuel saving and machine oil, minimizing spillage of material, reduce oil temperature, reduce exhaust gas discharging, and can be corresponding the increase cylinder pressure than, the advantage that improves engine power and prolong working lifes such as cylinder sleeve, piston and corresponding bent axle, connecting rod, camshaft, thereby overcoming the deficiencies in the prior art effectively, is a kind of comparatively desirable novel piston.

Description of drawings.

Accompanying drawing is a kind of embodiment's schematic representation of the present utility model.

Wherein: 1-cylindrical shell, 2-compression ring A, 3-compression ring B, 4-oil ring, 5-pin-and-hole, 6-radiation hole.

Below in conjunction with drawings and Examples the utility model is further described.

As shown in the figure, a kind of logical folded ring novel piston of spending of the present utility model, mainly form by cylindrical shell (1), compression ring A (2), oil ring (4), locate at cylindrical shell (1) top top compression ring A (2), set up one compression ring B (3), make and form folded ring herein, the collar extension of these two folded rings is partly taked to be staggered, its stagger angle is the best with about 180 °, have some and the radiation hole (6) that axially has certain inclination angle in the skirt section of its cylindrical shell pin-and-hole (5) both sides, the inclination angle of this radiation hole is 25 ° in an embodiment.Since the existence of above-mentioned folded ring with and being staggered of collar extension, making it wear and tear in use reduces and when being worn, can not produce leakage because of the existence of collar extension, simultaneously because the existence of radiation hole, its consumptive material is reduced, but also make its lubrication effect better, the piston body expansivity reduces, thereby reduce the wearing and tearing between piston and the cover cylinder effectively, prolong its working life

Claims

A kind of logical folded ring novel piston of spending, mainly form by cylindrical shell (1), compression ring A (2), oil ring (4), it is characterized in that cylindrical shell top top compression ring A (2) locates, set up one compression ring B (3), the collar extensions of two rings are taked to be staggered, and have some and the radiation hole (6) that axially has certain inclination angle in the skirt section of cylindrical shell pin-and-hole both sides.
