Abstract
The utility model provides a sealed piston gas ring in the field of internal-combustion engines. The sealed piston gas ring has the main characteristics that the connector of the gas ring adopts a spigot-shaped connector; after the improvement, not only two gas rings are arbitrarily assembled, but also the sealing performance is remarkably improved; gas leakage is not easy to happen even if the piston gas ring is abraded, so that the service life is prolonged. Furthermore, a sample shows that the power is increased compared with a comparison vehicle through installation and probation.
Description
Technical field
The utility model belongs to field of internal combustion engine, relates to piston, is specifically related to a kind of packed-piston compression ring.
Background technique
Existing internal-combustion engine, as the piston of tractor, motor car engine, its piston ring comprises an oil ring, two compression rings, the interface of its compression ring are neat mouthful.In piston when assembling,, it is harsh to require compression ring to cooperate, and piston just can impaired easy gas leakage within the next few days behind the installation heavy service, falls from exhaust emissions, causes the oil consumption waste, befouling environment, and the vehicle operation underpower, compression ring upgrades frequent, strengthens to consume.
The model utility content
The designer is in using tractor and vehicle maintenance thereof practice for many years, the piston gas ring of finding its motor exists easy gas leakage, the defective that needs frequent updating, through improving repeatedly, purpose is to provide a kind of packed-piston compression ring, can improve sealing, prolong the working life of compression ring, overcome the defective of existing piston gas ring preferably.
Technical solution adopted in the utility model is a kind of packed-piston compression ring of design, and its structure comprises: two compression rings, the interface of compression ring adopt seam shape interface.
Because change the interface of piston gas ring into seam shape interface structure by neat mouthful, not only two compression rings can arbitrarily assemble, and sealing significantly improves, even some wearing and tearing also is difficult for gas leakage, prolonged working life, reduced oil consumption, and vehicle operating is reliable.
Description of drawings
Fig. 1 represents the structural representation of the utility model packed-piston compression ring.
Embodiment
Reach embodiment in conjunction with the accompanying drawings, further specify the concrete structure of the utility model packed-piston compression ring, its feature and advantage are clearer.
The embodiment of the utility model packed-piston compression ring, referring to Fig. 1, its structure comprises: two compression rings 1, the interface 2 of every compression ring 1 adopts seam shape structure interface.Seam shape interface is applied to the housing interface combination of flame-proof motor, can avoid inflammable gas to enter in the motor field frame in inflammable and explosive place, has good explosion-proof performance; Seam shape interfacing is applied to piston gas ring improves, can better avoid oil gas in piston, to spill equally.Sample is installed on probation through trial-production, show that sealability significantly improves, and piston gas ring obviously prolongs more than ten times working life, and vehicle operation performance comparison improves according to vehicle power, is subjected to driver's favorable comment deeply.
Claims (1)
1, a kind of packed-piston compression ring comprises two compression rings, it is characterized in that the interface of compression ring adopts seam shape interface.
