Abstract

The utility model provides a piston ring comprising a ring body (1) with an opening, and is characterized in that the two end surfaces (2, 3) of the opening are crossed with each other; an upper cross body (4) and a lower cross body (5) at the end surface are hermetically assembled, and the cross section after being hermetically assembled is the same as that of the ring (1); the opening at the end surface does not leak gas, thereby preventing the leakage of the gas in a cylinder, increasing the heat efficiency of an internal-combustion engine, raising the doing-work efficiency of an engine and prolonging the service life of the piston ring.

Description

Staggered form opening piston ring

The utility model relates to a kind of piston ring, relates in particular to the piston ring that a kind of motor is used.

The piston ring of motor in the prior art, it comprises the ring body of being with opening, and two end faces of opening are the plane, and for the piston ring of new clothes in the piston circular groove, described two end faces generally are in contact with one another, and do not stay the slit.Along with using with the passing of time, the external diameter of piston ring weares and teares gradually, because the effect of elastic force, described two end faces also separate gradually, produce bigger slit.Directly have influence on the efficient of motor acting.Often need more rering, thereby the working life of piston ring is shorter.

The purpose of this utility model provides a kind of piston ring of motor, and it can prevent the leakage of gas in the jar effectively, has increased the thermal efficiency of internal-combustion engine, has improved the efficient of motor acting.Often do not need more rering, thereby the working life of piston ring is also longer.

To achieve these goals, the piston ring that the utility model provides is design like this: this staggered form opening piston ring, it comprises the ring body of being with opening, it is characterized in that: two end faces of described opening cross one another, the upward intersection body of end and the body seal combination of intersecting down, and the cross section after its seal combination is identical with the cross section of ring body.

Behind the piston ring that motor use the utility model provides,,, be subjected to the effect of elastic force,, also can not produce the slit though two end faces are shifted gradually though the external diameter of piston ring weares and teares gradually because its opening intersects each other.Thereby can not have influence on the efficient of motor acting.Often do not need more rering, thereby the working life of piston ring is also longer.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the schematic representation of piston ring of the prior art.Fig. 2 is the B-B section enlarged diagram among Fig. 1.Fig. 3 is that A-A among Fig. 1 is to enlarged diagram.As can be seen from the figure, piston ring comprises the ring body 1 of being with opening, and two

end faces

2,3 of opening are the plane, and in free state, two

end faces

2,3 are separated from one another.The piston ring of new clothes in the piston circular groove, described two end faces generally are in contact with one another, and do not stay the slit.Along with using with the passing of time, the external diameter of piston ring weares and teares gradually, because the effect of elastic force, described two end faces also separate gradually, produce bigger slit.

Fig. 4 is the schematic representation of the piston ring embodiment one in the utility model.The compound mode of its intersection has been enumerated three kinds in the accompanying drawings.Fig. 5 is the C-C section enlarged diagram of one first kind of combination of embodiment among Fig. 4.Fig. 6 is the D-D section enlarged diagram of one first kind of combination of embodiment among Fig. 4.Fig. 7 is the C-C section enlarged diagram of one second kind of combination of embodiment among Fig. 4.Fig. 8 is the D-D section enlarged diagram of one second kind of combination of embodiment among Fig. 4.Fig. 9 is the C-C section enlarged diagram of embodiment's one the third combination among Fig. 4.Figure 10 is the D-D section enlarged diagram of embodiment's one the third combination among Fig. 4.As can be seen, piston ring comprises the ring body 1 of being with opening from each figure, and two

end faces

2,3 of opening cross one another, the upward intersection body 4 of end and body 5 seal combination of intersecting down, and the cross section after its seal combination is identical with the cross section of ring body 1.

Figure 11 is the schematic representation of the piston ring embodiment two in the utility model.The compound mode of its intersection has been enumerated two kinds in the accompanying drawings.Figure 12 is the E-E section enlarged diagram of 2 first kinds of combinations of embodiment among Figure 11.Figure 13 is the F-F section enlarged diagram of 2 first kinds of combinations of embodiment among Figure 11.Figure 14 is the E-E section enlarged diagram of 2 second kinds of combinations of embodiment among Figure 11.Figure 15 is the F-F section enlarged diagram of 2 second kinds of combinations of embodiment among Figure 11.The logotype meaning of each figure is identical with embodiment one.
