Abstract
The utility model discloses an improved sealed piston ring, which comprises a piston ring body with an opening, an inclined gap groove is disposed on one end head of the ring opening, the upper side and the lower side of the inclined gap groove are respectively provided with an inclined end face, and an inclined plug post is disposed on the other end head of the ring opening, and the upper side and the lower side of the inclined plug post are respectively provided with an inclined end face. When the ring is disposed in the ring groove and the cylinder for operation, the inclined plug post is in sealing movable fit with the inclined plane of the inclined gap groove, the inserting and meshing length of the inclined plug post and the inclined gap groove is 2-6mm, and because the end face of the ring plug post in inserting and sealing movable fit with the gap groove is designed into the inclined plane, the upper part and the lower part, inside and outside of the gap of the ring opening are not communicated with one another when the ring is mounted into the ring groove and the cylinder for operation.
Description
Affiliated technical field
The utility model belongs to the improvement of internal-combustion engine piston ring, the particularly improved piston ring that seals.
Background technique
At present, the piston ring that known internal-combustion engine adopts is the ring bodies that has opening, and two top ends of its opening are the plane.When new piston ring was packed in annular groove and the cylinder, the opening two top end matching gaps of its ring were very little, but after work after a while, wear and tear gradually in the exterior edge face of ring, the opened gap of piston ring is increased, cause the leakage of gas, the not enough oil consumption of horsepower of internal-combustion engine is risen.
Summary of the invention
The purpose of this utility model is to provide a kind of improved piston ring that seals, can effectively reduce gas in the cylinder from collar extension clearance leakage and machine oil through ring opened gap string cylinder, prolong the working life of ring.
The utility model is achieved in that a kind of improved piston ring that seals, comprise piston ring body with opening, on a termination of gap-clearance of piston rings, the inclination gap slot is being set, two symmetrical side one sides of the inclined end face that inclination gap slot lower end is provided with are with crossing apart from the ring outer peripheral surface at ring 0.2-0.6mm place, upper-end surface, another side is with crossing apart from the ring lower end surface at ring inner peripheral surface 2-6mm place, two symmetrical side one sides of the inclined end face that is provided with on the inclination gap slot are with crossing apart from the ring inner peripheral surface at ring 0.2-0.6mm place, lower end surface, another side is with crossing apart from the ring upper-end surface at ring outer peripheral surface 2-6mm place, on another termination of ring opening, be provided with and inclination gap slot movingly inclination inserting column mutually, inclined end face is being set both sides respectively up and down at the inclination inserting column, the utility model ring be installed in piston ring groove and gas lack in the time inclination inserting column two inclined end faces up and down respectively with the plane of inclination, two ends up and down of inclination gap slot mutually the interleave sealing movingly, inclination inserting column and inclination the gap slot length that meshes of interleave mutually are 2-6mm.
Because the utility model piston ring, on a termination of ring opening, the inclination gap slot is being set, be provided with on another termination and inclination gap slot movingly inclination inserting column mutually, and inclination gap slot and inclination the inserting column fitting surface of side setting up and down are the plane of inclination, its advantage is: simple in structurely be easy to carry out plain grinding processing, the angled end-face that inclination gap slot and inclination inserting column are sealed movingly mutually has a good sealing.
Because two symmetrical side one sides of the inclined end face that inclination gap slot lower end is provided with are with crossing apart from the ring outer peripheral surface at ring 0.2-0.6mm place, upper-end surface, another side is with crossing apart from the ring lower end surface at ring inner peripheral surface 2-6mm place, two symmetrical side one sides of the inclined end face that is provided with on the inclination gap slot are with crossing apart from the ring inner peripheral surface at ring 0.2-0.6mm place, lower end surface, another side is with crossing apart from the ring upper-end surface at ring outer peripheral surface 2-6mm place, its advantage is: the utility model ring is not connected inside and outside making about the opened gap of ring when being installed in the piston ring groove and matching with cylinder, overcome interior gas leakage loss of ring opened gap increase rear cylinder and lubricant oil deficiency through collar extension gap string cylinder, improve combustion in IC engine quality and work power, prolonged the working life of ring.
Since the utility model ring inclination inserting column and inclination gap slot up and down the inclined end face of both sides be interleave sealing mutually movingly, can make the excircle end face of ring a good sealability that contacts be arranged when working in piston ring groove and the cylinder with the interior resonator end surface of cylinder so the utility model ring is packed into.Inclination inserting column and inclination the gap slot length of interleave engagement mutually are 2-6mm.
