Abstract
The invention discloses three-in-one double-closed combined compression ring for a reciprocating piston internal combustion engine. Compressed gas from the internal combustion engine and working gas produced after combustion can be effectively prevented from leaking, so that the aims of saving fuel oil and fuel gas and reducing carbon emission are fulfilled.
Description
The invention belongs to the piston machine Sealing, the two closed group of especially suitable reciprocating IC engine are closed the compression ring accessory.Be fit to liquid fuel internal combustion engines, also be fit to gas fuel engine.
Existing internal-combustion reciprocating-pisto piston ring all adopts the single compression ring of uncompensated formula.Because the compression ring wearing and tearing are big, cause gap increase between piston ring and cylinder wall in the use, thus the fuel consumption increase, Here it is, and common so-called power descends, and oil consumption increases, and the lubricating fluid qualitative change is bad faster, makes lubricating condition abominable.So, greatly increased the internal combustion engine use cost.
The invention provides a technological artifacts, improved the combustion in IC engine condition greatly.Not only can save fuel oil, combustion gas, reduce waste gas, and can keep the lubricating fluid cleaning.Because present technique has adopted gap wear-compensating measure, therefore, the use of combustion motor is not only economical, and environmental protection.
The present invention is complete, and combination is made of 4 parts.Be respectively ring 1, ring 2, ring 3, location Xiao 4.Location Xiao 4 dress rings 1 circular hole place.The location Xiao put on it, to give ring 2 location, do not allow ring 2 left-right rotation on horizontal plane.Ring 2 is pressed on rings.One recess is arranged in the top, establish in addition a ring at recess, for encircling 3.Ring 3 effect is at any time to encircling 2 because of the cylindrical wearing and tearing, causes to increase and compensate encircling 2 internal round chamber gap, that is to say that successive elimination is because encircling its inner chamber excesssive gap of circle wearing and tearing outside 2.
For this reason, this associative ring has formed two closures again.First closure is ring 1 and ring 2.Surely to set Xiao 4 be near this ring opening part diagonal angle because encircling 1, but greater than 90 degree.The opening of ring 2 places Xiao both sides, location, and so, the opening of ring 1 and ring 2 is offset in the plane greater than 90 degree, encircles 1 opening and does not overlap with ring 2 openings.Second closure is to be finished by ring 2 and ring 3.Encircling 2 upper-end surfaces is recesses, and the recess end face is the inclined-plane, and encircling 3 lower end surfaces is inclined-planes.Ring 3 places in the ring 2 upper end recesses, by falling bodies with under gas pressure, along the inclined-plane by being attached on the inclined-plane that encircles 2 recesses.When ring 2 cylindrical gauge wear, just the gap is increasing between its internal round chamber, and therefore, the crack was just compensated by ring 3 between this had become big, and this is second closure.
By two closures of this combination compression ring, its pressurized gas just be difficult to from piston ring gap and with crack between cylinder wall contacts leak.
Accompanying drawing 1 is the present invention's a structural representation.
Accompanying drawing 2 is structural representations of ring 1 of the present invention.
Accompanying drawing 3 is structural representations of ring 2 of the present invention.
Accompanying drawing 4 is structural representations of ring 3 of the present invention.
Below the contrast accompanying drawing is elaborated.
Claims (7)
1. two closed reciprocating IC engines combination compression ring hereinafter to be referred as the combination compression ring, is characterized in that: this ring is by ring 1, ring 2, ring 3 and locate Xiao 4 and form.
2. two closed reciprocating IC engines make up compression ring, and hereinafter to be referred as the combination compression ring, it is characterized in that: the base ring of this combination compression ring, namely encircling has location Xiao on 1.
3. according to the described combination compression ring ring of claim 1 and ring 2, by encircling 2 left-right rotation to stop between location Shaw set ring 2 openings that are positioned to encircle on 1.
4. the combination compression ring according to claim 1 is characterized in that: ring 2 is the inclined-plane with the mating face of ring 3.
5. according to claim 1 and 2 described combination compression rings, it is characterized in that: in the single piston ring position of assembling on this former piston, become many compression rings of combined type.
6. according to claim 1 and 2 described combination compression rings, it is characterized in that: ring 1, ring 2 be through Xiao 4 location, location, its two rings opening certain angle that mutually is shifted, and the opening of being convenient to this two ring does not overlap.
7. the combination compression ring according to claim 1 is characterized in that: ring 3 is put in the ring 2 upper surface diameters, and the cylindrical cavity crack compensates within 2 to encircling at any time.
