Abstract
The utility model discloses a combined piston ring which is used for the sealing of the piston of an engine or a gas compressor, comprising mainly a main ring (1) and a secondary ring (2). The inner diameter part of the ring opening of the main ring (1) is provided with a depressed groove, the other side in the diametrical direction corresponding to the ring mouth of the secondary ring (2) is provided with a positioning pin (3); during assembling, the positioning pin (3) is inserted into the depressed groove of the main ring (1), and the main ring (1) and the secondary ring (2) which are put together are arranged at a piston (4); the ring openings of the main ring (1) and the secondary ring (2) can also be manufactured into trapezium ring openings, and the main ring (1) and the secondary ring (2) are delimited by pin bolts in a trapezium ring groove of the piston (4) in an interleaving mode. The utility model has the advantages of simple structure, reduction of fabrication and high sealing performance.
Description
Be used for motor or gas compressor piston seal, a kind of compound piston ring.
Adopt of motor in the past or gas compressor piston encircled seal form more more, this sealing configuration one is that processing technology is complicated, the 2nd, along with the seal ring number increases its surface friction drag increase, thereby influence the power of motor.
The objective of the invention is, overcome above-mentioned shortcoming, change has the conventional construction mode of motor or gas compressor piston packing ring and has designed a kind of compound piston ring.
Be particular content of the present invention and most preferred embodiment below:
The present invention mainly is made up of main ring and inner loop, as shown in drawings, main ring 1 is provided with groove in the collar extension inner radius, inner loop 2 is being provided with locating stud 3 with the corresponding diametric(al) opposite side of collar extension, make locating stud 3 insert the groove of main ring 1 when assembling, main ring 1 and inner loop 2 are close together mutually and are contained on the piston 4.When on low-powered engine or gas compressor, using compound piston ring of the present invention, main ring 1 and inner loop 2 can be processed into collar extension trapezoidal collar extension, with pin with main ring 1 and inner loop 2 staggered being limited in the trapezoidal annular groove of piston.
Advantage of the present invention is:
1, simple in structure, be easy to make.
2, reduce the surface friction drag of piston ring to casing wall.
3, improved sealability.
Description of drawings:
Fig. 1 is the structural representation of main ring 1.
Fig. 2 is the assembling schematic representation of main ring 1 and inner loop 2.
Fig. 3 is the structural representation of inner loop 2.
Fig. 4 is inner loop 2 has trapezoidal collar extension at the collar extension place a structural representation.
Fig. 5 is main ring 1, inner loop 2 each assembling schematic representation when having trapezoidal collar extension.
Fig. 6 is main ring 1 has trapezoidal collar extension at the collar extension place a structural representation.
Claims (3)
1, a kind of compound piston ring, mainly form by main ring 1 and inner loop 2, it is characterized in that said main ring 1 is provided with groove in the collar extension inner radius, inner loop 2 is being provided with locating stud 3 with the corresponding diametric(al) opposite side of collar extension.
2, compound piston ring as claimed in claim 1 makes locating stud 3 insert the groove of main ring 1 when it is characterized in that assembling, main ring 1 and inner loop 2 are close together mutually and are contained on the piston 4.
