Abstract
The present invention relates to an axial null-leakage piston ring mechanism. Said piston ring is made into the form of circular ring with opening, and mounted in the ring groove of piston periphery, in every ring groove of described piston periphery at least two piston rings are mounted, and the opening positions of two piston rings are mutually alternated.
Description
Technical field
The present invention relates to the piston ring mechanism of cylinder piston.
Background technique
The cylinder piston mechanism of available engine is set with the piston ring that comprises compression ring and oil ring on its piston, this piston ring and cylinder inner wall rubbing contact.Because each piston ring all has an opening, even three piston rings that are contained in respectively in the piston ring groove are arranged, and the aperture position of each piston ring staggered mutually, these openings still can form the gas axial passage, gas can pass from this axial passage in the work, produces gas in the jar along the axial upper and lower leakage of piston ring, causes energy loss, increase oil consumption, reduce mechanical efficiency; The wearing and tearing of piston ring external diameter increase the opening on the piston ring circumference, the every increase of diameter 0.01mm, and the opening on the circumference then increases 0.03mm, and opening increases to a certain degree the back piston ring and just can not work again, need scrap.In addition, this gas leakage also can produce incomplete combustion, discharge of noxious gases, befouling environment.
Summary of the invention
The purpose of this invention is to provide a kind of axial zero leakage piston ring mechanism, the axial leakage of blocking-up gas in the jar is realized the axial zero leakage of gas in the jar; reduce oil consumption, improve mechanical efficiency, prolong the working life of piston ring; promote that exhaust emissions is up to standard, the favorable environment protection.
The object of the present invention is achieved like this:
A kind of axial zero leakage piston ring mechanism, this piston ring is the toroidal that opening is arranged, and is contained in the annular groove of outside piston, in each annular groove of described outside piston at least two piston rings is housed, and the aperture position of these two piston rings staggers mutually.
The opening shape of described piston ring is a rectangle, tiltedly parallel surface shape, projection groove insert a kind of in the shape.
The present invention has following actively useful effect:
This product is equipped with at least two piston rings in a piston ring groove, the aperture position of this each piston ring staggers mutually, forms axial channel-less sealing, thereby can realize that gas in the jar does not have axial leakage, reaches the reduction oil consumption, and energy saving improves mechanical efficiency.After piston ring used a period of time to cause gap-clearance of piston rings to increase because of the external diameter wearing and tearing, this product still can compensate the function that the blocking-up gas in the jar leaks, and prolonged piston ring working life, reduced user cost.This product realizes easily that also exhaust emissions is up to standard, the favorable environment protection owing to have the axial zero leakage function of gas in the jar.
Description of drawings
Fig. 1 is the piston ring structural scheme of mechanism of prior art;
Fig. 2 is the structural representation of an embodiment of the present invention;
Fig. 3 is the partial sectional view of Fig. 2.
Embodiment
Accompanying drawing number:
1. cylinder
2. piston 201. annular grooves
3. piston ring (compression ring) 301. openings
4. second piston ring (compression ring), 401. openings
5. oil ring 6. connecting rods
Fig. 1 shows the cylinder piston mechanism of prior art motor, in the annular groove of its piston 2, piston ring is housed, this piston ring comprises compression ring and oil ring 5, each piston ring is the annulus of opening, piston 2 articulated linkage 6, connecting rod 6 hinged bent axles (accompanying drawing does not show) drive crankshaft rotating at piston 2 connecting rod 6 when cylinder 1 moves up and down.A piston ring 3 only is housed in the annular groove of each piston 2 of prior art, because the opening 301 of each piston ring 3 can be interconnected, form the gas axial passage, cylinder 1 interior gas can pass from the opening 301 of piston ring 3 in the work, produces the axial leakage of gas.
Please refer to Fig. 2, Fig. 3, the present invention is an a kind of axial zero leakage piston ring mechanism, this piston ring 3 is the toroidal (same prior art) that opening 301 is arranged, be contained in the annular groove 201 of piston 2 cylindricals, in each annular groove 201 of described piston 2 cylindricals at least two piston rings are housed, in the diagram annular groove 201 piston ring 3 and piston ring 4 are housed, stagger mutually in the opening 301 of these two piston rings and the position of opening 401, thereby opening 301, the 401 impossible air passagewayss that form, thereby the axial leakage of air in the cylinder 1 is blocked.The quantity of the piston ring during enforcement in each piston ring groove 201 can for example be three more than two.The opening of its adjacent pistons ring must stagger.
During enforcement, the opening 301 of described piston ring 3 be shaped as rectangle, tiltedly parallel surface shape, projection groove insert a kind of in the shape, these are shaped as prior art, accompanying drawing does not show.The all applicable the technical program of these shaped aperture.
Claims (2)
1. axial zero leakage piston ring mechanism, this piston ring is the toroidal that opening is arranged, be contained in the annular groove of outside piston, it is characterized in that: in each annular groove of described outside piston at least two piston rings are housed, the aperture position of these two piston rings staggers mutually.
2. axial zero leakage piston ring as claimed in claim 1 mechanism is characterized in that: the opening shape of described piston ring is a rectangle, tiltedly parallel surface shape, projection groove insert a kind of in the shape.
