Abstract
The utility model relates to a high-airtightness labyrinth piston which comprises a piston, a cylinder body and a piston ring and is characterized in that an outer piston barrel is arranged on the outer cylindrical surface of the piston; a ring-shaped insertion slot is formed between the outer piston barrel and the piston; the outer cylindrical surface of the cylinder body is provided with an outer cylinder barrel; a ring-shaped insertion slot is formed between the outer cylinder barrel and the cylinder body; and the cylinder wall of the cylinder body is inserted into the ring-shaped insertion slot of the piston.
Description
Technical field
The sealing configuration of the utility model and a kind of engine piston, specifically a kind of high airtight labyrinth piston.
Background technique
At present, conventional engines piston is by piston ring packing, due to and cylinder body between to do continuous relative displacement, so inevitable gapped between piston ring and cylinder body, cause the acting gas leakage of high pressure, engine efficiency is declined.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high airtight labyrinth piston.
In order to solve the problems of the technologies described above, the airtight labyrinth piston of height of the present utility model, comprise piston, cylinder body, piston ring, is characterized in that, an outer piston cylindrical shell is set on the outer cylinder of piston, and between piston, form an annular slot, and on cylinder body outer cylinder, arranging between an outer shell cylindrical shell and cylinder body and form an annular slot, the casing wall socket joint of cylinder body enters in the annular slot of piston.
Between the casing wall of cylinder body and the annular slot of piston, be provided with inner carrier ring and outer piston ring.
Adopt the design's beneficial effect to be: by the design, to make the straight line type leakage way between original piston ring and cylinder body become mazy type leakage way, effectively stoped the leakage of high-pressure gas, improved the efficiency of motor.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the airtight labyrinth piston of height of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the airtight labyrinth piston of height of the present utility model is described in further detail.
As shown in the figure, the airtight labyrinth piston of height of the present utility model, comprise piston 2, cylinder body 1, piston ring, is characterized in that, an outer piston cylindrical shell 4 is set on the outer cylinder of piston 2, and between piston 2, form an annular slot, and on cylinder body 1 outer cylinder, arranging between an outer shell cylindrical shell 5 and cylinder body 1 and form an annular slot, the casing wall socket joint of cylinder body 1 enters in the annular slot of piston 2.
Between the casing wall of cylinder body 1 and the annular slot of piston 2, be provided with inner carrier ring 3 and outer piston ring 6.
