Abstract

At present, the common combination form of a piston and a piston ring which are used on cylinder class equipment, such as internal combustion engines, gas compressors, etc. is that the piston is provided with a plurality of piston ring grooves, and the inner part of each groove is provided with a piston ring. In practice, people find when the wearing amount of the piston ring and the cylinder is up to certain degree, the expanding amount of a piston ring opening is enlarged, and the phenomena of air leakage and oil leakage from the ring opening, powerless operation of the equipment, large oil consumption can occur during the operation. But the new combination form of piston rings and a piston with a groove for two rings is that two piston rings are arranged in each ring groove on the piston, the openings of the two piston rings are staggered consciously, the end surfaces of the two piston rings are tightly against one another under the action of high-pressure gas, and the mutual openings are blocked with each other by the end surfaces, so the gas can not leak from the opening part. The utility model has the advantages of favorable sealing property, oil saving, powerful working, long service life, etc.

Description

The new combining form of one groove and two rings piston and piston ring
The utility model belongs to the one groove and two rings piston of placing two piston rings on the piston of cylinder kind equipments such as internal-combustion engine, gas compressor in each piston ring groove and the new combining form of piston ring.
The cylinder kind equipment piston commonly used at present and the structure of piston ring all are that several roads piston ring groove is arranged on piston, all place a piston ring in each groove, this structure has been used for many years, find in the practice when the wear extent of piston ring and cylinder body arrives to a certain degree, the amount of the opening increase of piston collar extension, in the work under the effect of pressurized gas, will be from collar extension gas leakage, leakage of oil, equipment work is unable, and fuel consumption increases, so the life-span of piston ring and cylinder body is shorter.
The purpose of this utility model be propose a kind of can be from the gas leakage of piston collar extension, leakage of oil, combining form that efficient is high, the life-span is grown, piston and piston ring.
This cylinder kind equipments such as internal-combustion engine, gas compressor that are applicable to, the combining form of piston and piston ring is characterized in that in the annular groove on piston, connect the method for placing two piston rings in each groove and install, and the openings of two rings stagger consciously.
The utility model has the advantages that: good airproof performance, air tight, oil-proof, efficient is high, machine is strong, the long working life of piston ring and cylinder body.
Description of drawings, Fig. 1 are to put the piston of a ring and the old combining form of piston ring in the groove.Fig. 2 is put the one groove and two rings piston of two rings and the new combining form of piston ring in one groove.1 cylinder among the figure, 2 pistons, 3 piston rings.
Now in conjunction with the accompanying drawings working principle of the present utility model and working procedure are described in detail, three road annular grooves are arranged on the piston 2 among Fig. 1, place one piston ring 3 in each groove, under the effect of piston ring elastic force, the inner cylinder no-float of the outer cylinder of ring and cylinder barrel.Cylinder body 1, piston 2, piston ring 3 threes form a hyperbaric chamber.When in the hyperbaric chamber pressurized gas being arranged, pressurized gas will close direction along arrow by the opening on the piston ring 3 and spill a part.And the twice annular groove is arranged on the piston 2 in the utility model Fig. 2, place two piston rings 3 in each groove, two rings opening when placing staggers 180 °, and at this moment cylinder body 1, piston 2, piston ring 3 is formed the hyperbaric chamber of a sealing, when in the hyperbaric chamber pressurized gas being arranged, two rings in the groove tightly are close together, and pressurized gas can only pass the opening of first ring in first groove, will can not spill by the end face of second ring in first groove when living.Moreover, the twice annular groove is arranged on the piston, all place two piston rings in each road, after work a period of time, might have the moment of coincidence with the ring of two in a groove opening, but the probability of the opening coincidence simultaneously of the ring in the twice groove is just very little.Occurred exactly overlapping simultaneously, also can reach the identical effect of a groove one ring type.

Claims (2)

1. one kind is applicable to cylinder kind equipment, the one groove and two rings piston of piston and piston ring combining form and the new combining forms of piston ring such as internal-combustion engine, gas compressor.It is characterized in that in the annular groove on the described piston that install by the method for placing two piston rings in each groove, the opening of two rings will stagger consciously.
2. the new combining form of one groove and two rings piston according to claim 1 and piston ring is characterized in that on the piston it can being the twice groove.Also can be three road grooves.
