Abstract
The present invention relates to a triple combined piston ring for gasoline, diesel engine and air compressor. It is formed from two single rings and one inner ring. The upper ring, lower ring and inner ring are combined together and placed into a ring groove so as to form a compression ring, the combination of said three rings can produce mutual sealing action, and said structure always can retain good sealing state without regard to wear of collar extension. Said invention also provides its assembling method. Said piston ring has the advantages of good sealing property, high working efficiency and long service life.
Description
The invention belongs to the design and the manufacturing technology field of vapour, diesel engine, is the design and the manufacturing technology field of piston ring.
Present employed piston ring has the shortcomings such as increase of leaking gas along with wearing and tearing.
The objective of the invention is, a kind of three multiple-piece piston-rings are provided.
The present invention is achieved by the following technical solution:
Two on existing piston ring (monocycle) is done upper and lower ring, add ring in, these three rings are combined, become compression ring one in one annular groove of packing into.The collar extension position of upper and lower two rings becomes 90 °～180 ° angles, and the collar extension position of interior ring is in the middle of upper and lower two collar extensions become 90 °～180 ° angles.
Each piston only needs together or twice three multiple-piece piston-rings get final product.
Below in conjunction with accompanying drawing structure shape of the present invention and assembly relation are done and to be specified.
Fig. 1 is the plan view and the subjective figure (be in assembling condition, collar extension is a spreading under the normality) of the monocycle of upper and lower two rings.
Fig. 2 is interior ring plan view under the assembling condition and subjective figure.
Fig. 3 is the sectional view of three multiple-piece piston-rings on the piston of packing into.
Fig. 4 is three multiple-piece piston-ring diagrammatic cross-sectional view.
The 1-monocycle, the 2-collar extension, ring in the 3-, collar extension in the 4-, the last ring of 5-, 6-is ring down, ring in the 7-, the last ring of 8-chamfering, 9-is the ring acute angle down.
Piston ring of the present invention is three multiple-piece piston-rings, three associative rings are combined by ring 3 in upper and lower two monocycles 1 and, be encased in one annular groove as shown in Figure 3, last ring 5 with cooperate for bright and clean plane between the ring 6 down, and the inner headed face of upper and lower two rings 5,6 also cooperates for smooth surface with the periphery of interior ring 7, the height of ring in the height sums of upper and lower two rings equal, on be equipped with less chamfering or do not have chamfering all can be shown in 8, be equipped with the frizing acute angle shown in 9 down.
Material of the present invention, manufacture method are same as the prior art, and height, the width of upper and lower two rings are identical with the existing piston ring, and the available spring steel of interior ring or other resilient metallic material all can.
Sealing principle of the present invention:
When piston stroking upward compressed, main gas leakage gap was exactly a collar extension, played collar extension under being of main seal action in this structure, so the purpose of ring and interior ring is exactly to want collar extension under the shutoff on being fitted with in this structure, made down collar extension air tight or leak gas less.Following collar extension has four different faces, and these four faces make it go up plane, lower plane, inner headed face, periphery for the time being.
The effect of last ring is the last plane of collar extension under the shutoff, and the effect of interior ring is the inner headed face of collar extension under the shutoff, and the lower plane of collar extension under the lower plane shutoff of annular groove, the periphery of collar extension under the cylinder wall shutoff.Following collar extension just obtained the effect that the four sides is sealed, collar extension can increase gradually though piston ring is because of wearing and tearing down, the sealing principle of this structure is constant, so this structure can remain good sealing state.
Claims (1)
1, three multiple-piece piston-rings, it is circular ring with collar extension, it is characterized in that piston ring is three combined types, three multiple-piece piston-rings are to be combined by ring (3) in two monocycles (1) and, last ring (5) cooperates for the plane with following the ring between (6), the inner headed face of upper and lower two rings (5), (6) matches with the periphery of interior ring (7), last ring (5) is provided with less last chamfering or does not have chamfering all can, under be equipped with the frizing acute angle, the collar extension position of upper and lower two rings becomes 90 °～180 ° angles, and interior collar extension position is in the middle of upper and lower two collar extensions become 90 °～180 ° angles.
