Abstract
The utility model relates to a piston with two steam rings in a steam ring groove. The piston comprises a piston body, an oil ring and the steam rings, and is characterized in that: an oil ring groove and two steam ring grooves are formed on the piston body from top to bottom; an oil ring is arranged in the oil ring groove; and the two steam rings of which the ring openings are staggered and arranged in the two steam ring grooves respectively. The two steam rings of which the ring openings are staggered and arranged in the two steam ring grooves formed on the piston body, so the wear resistance of the steam rings of the piston is increased, the steam rings are not easy to open and leak after the steam rings are worn out, and then the normal start and run of an engine are ensured. The piston has the advantages of reasonable design, simple structure, convenience in operation and low construction cost.
Description
Technical field
The utility model relates to a kind of piston, exactly is a kind of piston that two vapour rings are installed in a vapour annular groove.
Technical background
The piston that uses is is all installed and used the vapour ring separately at present, promptly in the vapour annular groove on the piston vapour ring can only be installed, and the vapour collar extension will produce the phenomenon of dehiscing after the wearing and tearing of vapour ring, therefore is easy to gas leakage, makes motor can't start operation.
The model utility content
The utility model purpose is at existing problem, provides a kind of wear resistance that not only increases piston vapour ring to people, and has guaranteed that vapour ring wearing and tearing back is difficult for producing the piston that two vapour rings are installed of dehiscing and leaking gas in a vapour annular groove.
The utility model comprises piston body, oil ring and vapour ring, it is characterized in that: piston body from top to bottom and on have an oil ring groove and two vapour annular grooves, an oil ring is housed in the oil ring groove, two vapour rings that collar extension interlaces are housed respectively in the two vapour annular grooves.
Effect of the present utility model
1, the utility model is owing to be equipped with two vapour rings that collar extension interlaces respectively in the two vapour annular grooves that have on the piston body, therefore not only increased the wear resistance of piston vapour ring, and guaranteed that vapour ring wearing and tearing back is difficult for producing and dehisce and leak gas, thereby can guarantee the normal startup operation of motor.
2, the utility model is reasonable in design, and is simple in structure, easy to operate, cheap.
