Abstract
The utility model provides a two-way closure single piston ring for horizontal and vertical closure, which aims to solve the technical problems that in the existing single piston ring, the sealing performance is poor, the air leakage phenomenon occurs because the opening end is easy to pull apart after the piston ring is worn, etc. Both ends of an opening of a ring body are provided with two planes which are overlapped mutually, one end of the opening of the ring body is provided with an overlapping slot in the horizontal direction and an overlapping block is arranged vertical to the overlapping slot. The other end of the opening is provided with an overlapping block in the horizontal direction, and an overlapping slot is arranged vertical to the overlapping block. The utility model has the advantages of simple structure, two-way closure, favorable gas tightness, effective prevention of the gas leakage in a cylinder, high power of an internal combustion engine and high service lives of the piston ring and a cylinder body. The utility model is suitable for various piston type internal combustion engines.
Description
One, technical field
The utility model relates to a kind of piston ring, especially relates to a kind of single piston ring that is applied to internal-combustion engine.
Two, background technique
At present, the employed single piston ring of internal-combustion piston engine is and radially heads straight for mouth both at home and abroad, and the end face that newly is installed on two openings of the piston ring in the piston groove generally is in contact with one another, and does not stay the slit.Along with lengthening service time, the cylinder body wearing and tearing, ring body fluffs, and two end faces will produce big gap, and cylinder will leak gas like this, has increased fuel consumption, influences the working efficiency of internal-combustion engine.For addressing the above problem, the someone has invented the piston ring that a kind of ring body opening end is provided with two mutual superposition faces, can improve that ring body wearing and tearing opening fluffs and the phenomenon of leaking gas.But along with the lengthening of service time, opening end still has necessarily and draws back, and spills from the slit that stack face draws back with regard to having gas like this, and phenomenon still can leak air.
Three, summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly is provided with the two-way single piston ring of covering mouthful of level and vertical direction at the gap-clearance of piston rings end, when ring body weares and teares, can guarantee in ring body substantially horizontal and vertical direction all air tight, to improve engine operation efficient, fuel saving.
The utility model is achieved in that
In order to be implemented in the two-way mouth of covering of gap-clearance of piston rings end level and vertical direction, on the plane that the both ends horizontal direction and the vertical direction of ring body opening is equipped with two mutual superposition; End substantially horizontal at the ring body opening is provided with a stack groove, with the vertical stack piece that is provided with of stack groove; The other end substantially horizontal at opening is provided with the stack piece, with the vertical stack groove that is provided with of stack piece.
In order to make the two-way sealing effect of covering mouthful better, the stack groove of substantially horizontal is wide identical with the stack block length, and the degree of depth of stack groove is identical with the thickness of the piece that superposes; The stack piece of vertical direction is wide identical with the stack flute length, and wide is the thickness of piston ring ring body, and the thickness of stack piece is identical with the degree of depth of stack groove.
Good effect of the present utility model is: simple in structure, air-tightness is given prominence to, when piston ring and cylinder body long-term operation, after wearing and tearing strengthen, under the elastic force effect, when opening increases, level and vertical two directions all can be covered a mouthful sealing, opening end can not produce the slit, thereby can not leak gas, and has prevented the gas in the jar leakage, improved power of IC engine, the working life that also can improve piston ring and cylinder body simultaneously.The utility model can be widely used in various internal-combustion piston engines.
Four, description of drawings
Fig. 1 is the structural representation under the free open configuration of the utility model.
Fig. 2 is that the A of Fig. 1 is to partial view.
Five, embodiment
As shown in Figure 1 and Figure 2, the utility model is on plane that the both ends horizontal and the vertical direction of ring body 1 opening is equipped with mutual superposition, be the stack groove 2 and the stack piece 4 of substantially horizontal mutual superposition, the stack piece 3 of vertical direction mutual superposition and stack groove 5, stack groove 2 is opened in an end substantially horizontal of ring body opening, with the stack groove 2 vertical stack pieces 3 that are provided with; Stack piece 4 is arranged on the other end substantially horizontal of opening, with the stack piece 4 vertical stack grooves 5 that are provided with.The utility model new clothes are in piston the time, and stack piece 4 is superimposed with stack groove 2, and stack groove 5 is superimposed with stack piece 3, the opening closure.Piston ring and cylinder body experience wear are under footpath outward force or self radical elasticity effect, when gap-clearance of piston rings increases gradually, slight displacement takes place in groove 2 though stack piece 4 superposes relatively, but overlapping portion still can be covered mouth, prevents that combustion gas from leaking from opening, has realized that substantially horizontal covers a mouthful sealing; After long-time use, wearing and tearing strengthen, and big displacements take place stack piece 4 stack grooves 2 relatively, and its both side clearancies are excessive, and stack piece 3 is superimposed with stack groove 5, can prevent combustion gas clearance leakage from the side, have realized that vertical direction covers a mouthful sealing.
When stack groove 2 is identical with stack piece 4 length and width, the degree of depth of stack groove 2 is identical with the thickness of stack piece 4, and when newly being installed on the piston, stack groove 2 is superimposed fully with stack piece 4, does not have the slit between the two, ring body 1 substantially horizontal cover mouthful effect meeting better; The piece 3 that in like manner superposes is identical with stack groove 5 length and width, and wide be the thickness of piston ring ring body, and when the degree of depth of the thickness of stack piece 3 and stack groove 5 was identical, the stack piece 3 and the groove 5 that superposes were superimposed fully, and mouthful effect of covering of ring body 1 vertical direction also can be better.
Implementation example, the utility model can adopt following compact dimensions: stack groove 5, stack piece 3 length are 8 millimeters, and width is 1.5 millimeters, and the thickness of the degree of depth of stack groove 5 and stack piece 3 all equates with the axial thickness of piston ring; Stack groove 2, stack piece 4 length are 8 millimeters, and the radial width that width is piston ring deducts 1.5 millimeters, the thickness of the degree of depth of stack groove 2 and stack piece 4 be piston ring axial thickness 1/2nd.The utility model can adopt the production of existing piston material and technology.
