Abstract
The utility model relates to a steam ring of an internal combustion engine, which is mainly composed of a ring body with an opening. The utility model is characterized in that two end parts of the opening of the ring body are respectively provided with notches and bulges, and the notches and the bulges are mutually corresponding to form tight matching, and sealing performance of the steam ring of the internal combustion engine is enhanced. The utility model has the effects of simple structure, good sealing, no leakage and long service life.
Description
The utility model relates to the internal-combustion engine vapour ring that a kind of reciprocating internal combustion engine vapour ring, particularly a profit have improved the vapour ring interface.
For guaranteeing the sealing of cylinder of internal combustion engine, used vapour ring all is provided with an opening now, and the ring body two end part of opening are plane contact, and one of formation is just round after the closure of openings.The vapour ring forms breach because to-and-fro motion in cylinder after use a period of time, wearing and tearing will occur at opening, causes disappointing, gas leakage, influences the working life of vapour ring.
The purpose of this utility model is to provide the internal-combustion engine vapour ring of a kind of long service life, good airproof performance.
The utility model is achieved in that
A kind of internal-combustion engine vapour ring mainly is made up of the ring body of band opening, it is characterized in that: on two end faces of described ring body opening, respectively be provided with a recess, make projection of formation on this end another side, this projection is corresponding with the recess of another end.
After the utility model adopts above structure, cooperate contact owing to change the plane contact of vapour ring opening into staggered form, improved the sealability of vapour ring, have simple in structure, easily manufactured, good seal, undismayed effect, the working life of vapour ring can be prolonged, 2-3 can be improved working life doubly.
Accompanying drawing is a kind of structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that ring body, 2 is that recess, 3 is projection.
As shown in drawings, the utility model is a kind of internal-combustion engine vapour ring, mainly is made up of the ring body 1 of band opening, has a recess 2 above the end at this of ring body 1 opening, makes projection 3 of following formation of this end; Below another end, also have a recess 2 accordingly, make this end top also form a projection 3; Described recess 2 is corresponding with the projection 3 of another end respectively, and opening forms and to closely cooperate during sealing, ring body 1 surround one 360 ° just round.
The thickness of above-mentioned recess 2 is generally half of ring body 1 thickness, can guarantee the sealing of ring body 1 like this, does not influence the intensity of vapour ring again.Above-mentioned recess 2 and projection 3 also can be located on the interior outside of ring body 1.The shape of recess 2 and projection 3 can be designed to cuboid shape.
When practical operation, can on an end of former ring body 1, leave a recess 2, on another end, install a projection 3 additional, form an improved vapour ring.Vapour ring can replace former internal-combustion engine with polynary vapour ring.
Claims (2)
1. internal-combustion engine vapour ring, mainly form by the ring body (1) of band opening, it is characterized in that: on two end faces of described ring body (1) opening, respectively be provided with a recess (2), make to form a projection (3) on this end another side, this projection (3) is corresponding with the recess (2) of another end.
2. internal-combustion engine vapour ring according to claim 1 is characterized in that: the thickness of described recess (2) is half of ring body (1).
