Abstract
The utility model relates to a kind of zero-clearance, sealing energy-saving piston ring, is that the straight cut with the conventional piston ring changes the cascade port into, forms the double-deck complementary structure of piston ring.That is: in the both ends of the surface of port, an end forms working surface, and the other end forms down working surface, can closely cooperate after upper and lower two otch of both ends of the surface embed mutually.The utlity model has nothing gas leakage, efficient, feature of long life, can make each oil dripping performance effect, reach zero-clearance, sealing, efficient, energy-conservation, stable performance.
Description
Technical field
The utility model relates to engineering part, is specifically related to energy-conservation, the gapless piston ring that use on internal-combustion engine, air compressor and all reciprocating machines.Belong to International Classification of Patents F16J9/00 " piston ring " technical field.
Background technique
The piston ring that uses in the prior art, its counterpart blow-by, after use a period of time, because wearing and tearing, opened gap strengthens, and causes serious gas leakage, and power descends, the oil consumption rising.Generally have to abandon need not, therefore increased the consumption of piston ring greatly.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of energy-efficient, the piston ring of zero-clearance, sealing.
The technical solution of the utility model is as follows.
A kind of zero-clearance, sealing energy-saving piston ring, be that straight cut with the conventional piston ring changes the cascade port into, form the double-deck complementary structure of piston ring, that is: in the both ends of the surface of port, one end forms working surface, the other end forms down working surface, can closely cooperate after upper and lower two otch of both ends of the surface embed mutually.
The last working surface that forms, its thickness be greater than the thickness that descends working surface, thereby increased working strength.
Whole piston ring is made up of two stepped end chomas and an oil ring.
The utility model of Shi Xianing has nothing gas leakage, characteristics of high efficiency like this, can make each oil dripping performance effect, reaches zero-clearance, sealing, efficient, energy-conservation, and the long lifetime, the work of stable performance can also be eliminated the influence of expanding with heat and contract with cold and causing simultaneously.
Description of drawings
Accompanying drawing is the structural representation of the utility model zero-clearance, sealing energy-saving piston ring.
Among the figure: 1, go up working surface, 2, working surface down.
Embodiment
As shown in drawings, the utility model zero-clearance, sealing, efficient, long-life energy-saving piston ring, form the cascade port in the port of ring, that is: an end-grain cutting goes to the bottom of outer toroid to form the otch of working surface 1, and the top that the other end cuts outer toroid forms down the otch of working surface 2.During work, two otch embed mutually, and formation closely cooperates.The important differentiation of working surface has been the difference of thin and thick up and down, to be more suitable in working procedure.
Claims (2)
1, a kind of zero-clearance, sealing energy-saving piston ring, it is characterized in that: be that straight cut with the conventional piston ring changes the cascade port into, form the double-deck complementary structure of piston ring, that is: in the both ends of the surface of port, one end forms working surface, the other end forms down working surface, can closely cooperate after upper and lower two otch of both ends of the surface embed mutually.
2, zero-clearance according to claim 1, sealing energy-saving piston ring is characterized in that: the formed working surface of going up, its thickness is greater than the thickness of following working surface.
