Abstract
The utility model relates to a piston, which is a reciprocating piston with a piston ring, particularly the reciprocating piston used for internal combustion engines or air compressors. The utility model has a piston body, the piston body is provided with piston ring grooves, piston air rings or piston oil rings are arranged in the piston ring groove, and two or three piston air rings whose openings are each other staggered are arranged in a piston ring groove. The opening end of the piston air ring forms an incline or a staircase shape.
Description
The utility model relates to the reciprocating piston of a kind of piston, particularly internal-combustion engine or used for air compressor.
The compression ring of the reciprocating piston of existing internal-combustion engine or used for air compressor is generally a groove and adorns a ring, on the common piston two to three road compression rings are arranged, oily together, after the piston ring long-time running wearing and tearing, gap-clearance of piston rings increases gradually constantly increases gas leakage, causes efficient and power to descend.Need to change piston gas ring after using certain hour.
The purpose of this utility model provides a kind of design proposal that the reciprocating piston of piston ring is arranged, and the sealability of this piston is better, the working life of favourable prolongation piston gas ring, the performance driving economy and the output power of raising internal-combustion engine or air compressor.
The technical solution of the utility model is: a kind of reciprocating piston that piston ring is arranged, piston body is arranged, the piston ring groove is arranged on the piston body, piston gas ring or oil piston ring are housed in the piston ring groove, two or three piston gas rings that opening staggers each other are housed in the piston ring groove.
The piston gas ring that is equipped with in the piston ring groove is made of compression ring in outer compression ring of piston and the piston, compression ring is inlaid in the groove of the outer compression ring of piston in the piston, and the opening of the outer compression ring of compression ring and piston staggers in the piston, increase sealing effect, be embedded with compression ring in two to three pistons that opening staggers each other simultaneously in the outer compression ring groove of piston, so that the raising sealability, reduce or prevent gas leak phenomenon.In order further to improve the sealability at gap-clearance of piston rings position, the piston gas ring opening end may be made in the inclined-plane or is stairstepping.In outer compression ring of piston and the piston.The opening end of compression ring also may be made in the inclined-plane or is stairstepping.
Be evenly equipped with three to four skirt ledge on the periphery in piston body skirt section, be used for guiding.
Major advantage of the present utility model is: help increasing the mechanical sealing performance between piston and cylinder sleeve, improve operational efficiency and output power, prolong the working life of piston ring.
Below in conjunction with drawings and Examples the utility model is further specified:
