Abstract

The utility model is composed of the stacking of two rings (1) and (2). The shape of an opening of the ring (1) is a straight cutting opening (4). The shape of an opening of the ring (2) is an oblique cutting opening (3). The angle alpha formed by the oblique cutting opening (3) and the plane of the ring is 35 DEG to 55 DEG. The oblique cutting opening (3) can be oblique from the upper part to the left lower part, and can also be oblique from the upper part to the right lower part. When the utility model is practically used, the ring (1) is arranged on the ring (2), and is mutually stacked. The ring (2) is arranged on the ring (1), and is stacked and used. The openings of the two rings (1) and (2) are mutually staggered, and are in arrangement of 180 DEG. The utility model reduces the air leakage quantity of the air cylinder, increases the pressure of the air cylinder, causes the fuel to be sufficiently combusted, and has the energy saving and the environmental protection functions.

Description

A kind of self-enclosed complementary energy-conserving and environment-protective piston ring

The utility model relates to the piston ring of internal-combustion engine.

Traditional internal-combustion engine piston ring is a groove one ring structure, and in actual application, because wearing and tearing constantly increase the piston ring working clearance, so that sealability descends, air leakage increases, and power descends, and oil consumption increases.In order to improve sealing, often adopt the multiple tracks compression, but the annular groove number increases and makes that piston is elongated to be increased the weight of, increased materials consumption thus and inertial force is increased; In recent years the one-slot and double ring structure of Chu Xianing because the ring opening is the straight cut shape, is easy to make the register of two rings under gas pressure and causes gas leakage, so do not reach the purpose that improves sealability.

The purpose of this utility model is; design a kind of self-enclosed complementary energy-conserving and environment-protective piston ring, it can make in actual use because the rotation of ring itself when causing register; automatically realization is staggered mutually and is reached the purpose of sealing mutually once more, and sealability is guaranteed.

The technical solution of the utility model is; described self-enclosed complementary energy-conserving and environment-protective piston ring is formed by two rings is folded mutually; wherein the opening shape of a loop is a straight cut, and the opening shape of another loop is an angular cut, described angular cut and ring plate plane angulation α=and 35 °～55 °.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings:

Fig. 1 is the structural drawing of a kind of embodiment's band broken section;

Fig. 2 is the structure of looking up of member shown in Figure 1;

Fig. 3 is that opening is the ring plate partial structurtes of straight cut;

Fig. 4 is the ring plate partial structurtes of the angular cut that square neck was oblique to left down on opening was served as reasons;

Fig. 5 is that opening is served as reasons and gone up ring plate partial structurtes to the angular cut of lower right inclination;

Fig. 6 is the self-enclosed fundamental diagram of ring plate (wherein arrow A is an airflow direction).

In the accompanying drawings: 1,2-ring, 3-angular cut, 4-straight cut.

By Fig. 1 and Fig. 2 as can be known, the utility model is formed by two rings (1) (2) is folded mutually, wherein the opening shape of ring (1) is a straight cut (4) (referring to Fig. 3), the opening shape of another loop (2) is angular cut (3) (referring to Fig. 4 and Fig. 5), described angular cut (3) and ring plate plane angulation α=35 °～55, this angular cut (3) can be shown in Figure 4 oblique by last square neck to left down, also can be shown in Figure 5 being tilted to the lower right by last.Described straight cut (4) is meant this otch or near normal vertical with the ring plate plane.During actual the use, the ring (2) that the ring (1) that straight cut (4) are arranged with a slice and a slice have angular cut (3) poststack is mutually inserted in the piston ring groove, it can be ring (1) that straight cut (4) are arranged last and ring (2) that angular cut (3) are arranged under to constitute two ring (1) (2) folded mutually; Also can be ring (2) that angular cut (3) are arranged last and ring (1) that straight cut (4) are arranged under to constitute two ring (1) (2) folded mutually.

Know-why of the present utility model is, referring to Fig. 6, when two encircle (1) (2) register, pressurized gas from the piston crown firing chamber will leak (arrow A direction in referring to figure) along opened gap downwards, and form one air-flow, when high pressure draught impacts the opening surface of the ring (2) with diagonal cut joint (3), stream pressure P will resolve into the component P of parallel piston ring in-plane ₁Component P with vertical piston plane of a loop direction ₂, hence one can see that, and it is parallel to the component P on piston ring plane ₂To promote ring (2) has the ring (1) of straight cut (4) to make circular movement (two ring plates produce complementary) relatively, thereby realizes two rings (1) (2) up and down to stagger mutually and reach the purpose of automatic sealing.

As known from the above, the utility model is self-enclosed complementary energy-conserving and environment-protective piston ring, and it significantly reduces the cylinder air leakage, and cylinder of internal combustion engine pressure increases, and fuel combustion is more thorough, discharge cleaner, thereby reach energy saving and protect the effect of environment.

Embodiment: according to the piston ring of accompanying drawing 1,2 and said structure, size and make with material and all require to determine with reference to the correlation technique of prior art is got α=45 °, and when installing and using, two rings (1) (2) aperture position staggers mutually 180 ° and is advisable.
