Abstract
The utility model relates to a novel piston ring in a bowl sharp, wherein a through hole used for the sleeve joint of the head part of a piston. In the utility model, the piston ring is in the bowl sharp; when the piston is in a compression stroke, the bowl-shaped piston ring is expanded transversely under the action of the pressure of a pressure chamber, thereby increasing the pressure on a cylinder wall, improving the leak tightness and increasing the output air pressure; when the piston is in an air suction back stroke, the bowl-shaped piston ring is under stress decreased gradually, the transverse deflection of the piston ring is decreased, the pressure on the cylinder wall is decreased gradually, the friction force between the piston ring and the cylinder wall is reduced, the abrasion is reduced, and the service life of the piston ring is prolonged.
Description
Technical field:
The utility model relates to a kind of novel piston ring.
Background technique:
The piston ring shape of generally using is annular at present, and the shape in cross section all is the rectangle of rule, when piston in compressed action and inflation process, the amount of deformation that piston ring produces is all at the traffic direction of piston, piston ring is constant all the time to the pressure of casing wall, so just cause the wear of piston-rings amount bigger, need to change regularly.
Summary of the invention:
The purpose of this utility model is to provide a kind of novel piston ring, and this piston ring helps reducing the mill sassafras with casing wall, has prolonged the working life of piston ring greatly.
The utility model piston ring is characterized in that: described piston ring is bowl-shape, and described bowl-shape bottom is provided with the through hole in order to the piston crown socket.
Piston ring of the present utility model is bowl-shape, and when piston during in compression procedure, bowl-shape piston ring is lateral expansion under pressure chamber's pressure effect, and cylinder-wall pressure is increased, and sealing improves, and has improved output pressure; When piston during in air-breathing backhaul, the pressure that bowl-shape piston ring is subjected to diminishes gradually, and piston ring lateral deformation amount also diminishes, and is also gradually little to the pressure of casing wall, and the frictional force of piston ring and casing wall reduces, and has reduced wearing and tearing, has prolonged the working life of piston ring.
Description of drawings:
Fig. 1 is the organigram of existing piston ring;
Fig. 2 is an organigram of the present utility model.
Embodiment:
The utility model piston ring is bowl-shape, and bowl-shape bottom 1 is provided with the through hole 2 in order to the piston crown socket.
Piston ring is made by plastic material, and plastic material can be a teflon etc.
Remarkable advantage of the present utility model: one, simple in structure, reasonable in design, two, little, the long service life of wear of piston-rings amount.
The utility model is mainly used on the two-stroke piston, does not particularly have on the oil gas pump at direct current and uses, and can reduce the wear of piston-rings amount greatly, prolongs the working life of piston ring.
Though the existing preferred embodiment of the utility model discloses as above, be not that any cross section is the scope that bowl-shape piston ring with through hole all belongs to the utility model protection in order to qualification the utility model.
