Abstract
The utility model discloses a seal piston ring type piston comprising a piston body, at least one piston ring groove is arranged at the upper end of the piston body, and among the piston grooves at least one piston groove is internally equipped with an integral piston ring and a semi-piston-ring, or two piston rings, or two piston rings and a semi-piston, or three piston rings, or more than three piston rings. The structure and material of the piston rings are the same as the that of the piston ring in the prior art, each piston ring is equipped with an opening, and disposing position of each piston ring in the piston groove is staggered with that of the opening of the piston ring. Additionally, the semi-piston-ring is a half of the integral piston ring and is disposed at a position aligned to the opening of piston ring in the same groove, and at least one piston ring is arranged in the other piston ring groove on the piston body. The utility model is adaptable to pistons of internal combustion engine, pneumatic devices, hydraulic devices and the like, which is good in sealing property and high in efficiency of saving energy and environment protection.
Description
Technical field
The utility model belongs to a kind of piston, and concrete is, and a kind of piston, particularly sealability that is used for devices such as internal-combustion engine, hydraulic pressure, air pressure is better, has the piston of effects of energy conservation and environmental protection.
Background technique
The use of piston is very extensive, and particularly piston is unusual important components in the internal-combustion engine, and its performance is determining the quality quality of machine.For efficient energy-conservation and the raising internal-combustion engine, people have proposed the technology and the product of a lot of improvement pistons, and these technology and product mostly have certain practical value, still, still require further improvement technology, with the performance of further raising energy-conserving and environment-protective about piston.
The model utility content
The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of packed-piston ring type piston, these piston seal better effects if, energy-conserving and environment-protective more.
The purpose of this utility model is achieved through the following technical solutions: packed-piston ring type piston, be provided with piston body, be provided with in the upper end of piston body and be provided with a piston ring groove at least, in this piston groove, have at least to be provided with a whole piston ring and a halfbody piston ring in the piston groove, perhaps be provided with two piston rings, perhaps be provided with two piston rings and a halfbody piston ring, perhaps be provided with three piston rings, perhaps be provided with the piston ring more than three; The structure of this piston ring is identical with the piston ring of prior art with material, and each ring is provided with an opening, staggers mutually for the opening of its piston ring in the position that described piston ring is placed in piston groove; Described halfbody piston ring is half of whole piston ring, and the position that is placed in the piston ring groove is an opening of it being aimed at the piston ring in the same groove; A piston ring is set in other the piston ring groove on the piston body at least.
Piston of the present utility model is provided with more than one piston in a piston groove, its opening staggers mutually, forms a totally enclosed ring, so sealing effect is good especially.Piston of the prior art staggers though the piston ring in its adjacent slot also is an opening, and is bigger at interval, so its sealing effect is influenced.The utility model compared with prior art has simple in structurely, and sealing effect is good especially, and the efficient of piston is higher, more energy-conserving and environment-protective.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of piston ring of the present utility model;
Fig. 3 is the structural representation of halfbody piston ring of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described: embodiment: packed-piston ring type piston, be provided with piston body 1, be provided with two piston ring grooves 2,3 in the upper end of piston body, in these two piston grooves, above be provided with two solid piston rings 2.1,2.2 in a piston groove 2, the structure of this piston ring is identical with the piston ring of prior art with material, each ring is provided with an opening 2.11, and the position that described piston ring is placed in piston groove is that the opening of two piston rings staggers mutually; A piston ring 3.1 is set in another piston ring groove 3.
Present embodiment is through on probation on car combustion engine, and effect is good especially, and is obviously more fuel-efficient than the similar internal combustion that uses existing piston, and power is strong, and drive performance obviously improves.
Claims (1)
1, a kind of packed-piston ring type piston, be provided with piston body (1), it is characterized in that: be provided with at least one piston ring groove (2,3) in the upper end of piston body, in this piston groove, have the piston ring that is provided with a whole piston ring and a halfbody in the piston groove at least, perhaps be provided with two piston rings (2.1,2.2), perhaps be provided with the piston ring of two piston rings and a halfbody, perhaps be provided with three piston rings, perhaps be provided with the piston ring more than three; The structure of this piston ring is identical with the piston ring of prior art with material, and each ring is provided with an opening (2.11), staggers mutually for the opening of its piston ring in the position that described piston ring is placed in piston groove; Described halfbody piston ring (4) is half of solid piston ring, and the position that is placed in the piston ring groove is an opening of it being aimed at the piston ring in the same groove; A piston ring is set in other the piston ring groove on the piston body at least.
