Abstract
The utility model relates to a piston and a piston ring component, belonging to the technical field of the piston and the piston ring of an internal-combustion engine. Three original air ring grooves are changed into one air ring groove on the basis of the existing piston and the existing piston ring component. The width of the air ring groove is two times slightly larger than the width of an air ring. Two branch air rings are placed, and the openings of the two branch air rings are staggered. The design of the piston and the piston ring component is artful. The piston and the piston ring component not only effectively solve the air leakage problem which is caused due to the openings of the air rings and improve the sealing performance of a cylinder, but also have convenient processing and air ring saving; meanwhile, the service life of a cylinder system can be enhanced.
Description
The utility model belongs to the internal combustion engine technical field, relates to the improvement of a kind of piston, piston-ring packing.
The piston, the piston-ring packing that generally use in the prior art all are that an oil ring groove is opened in the lower part of piston side, place oil ring, and upper side is opened two～four road compressions, and each places a compression ring.This assembly, although several compression ring openings interlace, since separated by a distance between each compression ring, so still form the passage that loses heart, cause and let out, and heat-energy losses consequently influences internal-combustion engine and exerts oneself.For solving disappointing problem, application number 90214189 has disclosed the piston ring scheme that a kind of opening two ends become the ladder surface design in the applying date 900808 " a kind of piston ring ", this scheme can make the piston ring gap leakage way seal automatically, thereby improved the sealability of cylinder ...But the piston ring ladder surface opening of this scheme, difficulty of processing is big, the technological requirement height.Still exist the amount of finish of piston ring groove big in addition, the plug ring consumption is many, wasting problem.
Task of the present utility model provide a kind of simple in structure, the piston amount of finish is few, the piston ring difficulty of processing is little, processing technology requires low, good seal performance, and piston, the piston ring group that can prolong its working life, to overcome the above-mentioned shortcoming of prior art.
The utility model lower part of piston side has oil ring groove, is placed with oil ring, and upper side has compression, is placed with compression ring, and its main points are that compression is that width is slightly larger than two times of compression ring width, is placed with two compression rings together, and the opening dislocation.
Fig. 1 is a plan view of the present utility model
Fig. 2 is a side view of the present utility model
Fig. 3 is that compression ring of the present utility model is arranged plan view
Below in conjunction with accompanying drawing the utility model is elaborated:
According to Fig. 1, Fig. 2, shown in Figure 3,3 is pistons among the figure, and the lower part of piston side has oil ring groove 2, is placed with oil ring; Upper side has compression 5 one, and its width is slightly larger than two times of compression ring width, is placed with two compression rings 4, and the residual gap of groove equals routine and requires the gap, and opening 6 dislocation of two compression rings.
Because the piston long-term work, for preventing compression ring 4 contingent rotations, two compression ring openings are overlapped, form leakage way, cause disappointing, above-mentioned said opening dislocation, angle should be the bigger the better, at least should be greater than 30 °.
The utility model adopts the compression that is slightly larger than two times of compression ring width together, place the compression ring that two branch ostium interlace, be skillfully constructed, not only solved the disappointing problem that causes because of the compression ring opening effectively, improved the sealability of cylinder greatly, and easy to process, save compression ring, the working life that can improve cylinder system simultaneously.
Claims (2)
1, a kind of piston, piston-ring packing, the lower side of piston 3 has oil ring groove 2, is placed with oil ring 1, upper side has compression 5, is placed with compression ring 4, it is characterized in that compression is one, width is slightly larger than two times of compression ring width, is placed with two compression rings 4, and opening 6 dislocation.
2, piston according to claim 1, piston-ring packing is characterized in that said opening 6 dislocation, and its dislocation angle is greater than 30 °.
