Abstract
The utility model relates to an air seal piston ring for internal combustion engine and air compressor, comprising a loop whose inner diameter and outer diameter are respectively made-up with a piston groove and an inner diameter of a cylinder. Wherein, one in three of the width of the circular ring is cut out at the left open end of the loop, but two in three of the width of the circular ring is cut out at the right open end, and both parties are mutually lap jointed and made-up. A moon semilunar groove is arranged at the middle part of the outer cylindrical surface of the left and right open ends. A moon semilunar sheet pin and the moon semilunar groove are movably made-up. The utility model changes original composite structure formed by three rings into the structure formed by one ring and one moon semilunar sheet pin, and the intensity of the ring is enhanced. The breach of the loop is blocked off by the moon semilunar sheet pin, and both parties are mutually matched, and the defect that the gap is enlarged cause by abrasion is overcame. The seal air and seal oil effect of the breach part of the ring has constant effect. In this way, the complete machine of the internal combustion engine or air compressor can save lubricating-oil 85 percent, and the availability ratio of the complete machine fuel oil is improved 9 percent. As a result, the operation cost of the complete machine is degraded and the useful life of the cylinder and piston are prolonged.
Description
Technical field
The utility model relates to a kind of piston packing ring, is the improvement of gas seal piston ring structure in internal-combustion engine or the air compressor specifically.
Background technique
Oil seal ring and gas seal ring are housed between the cylinder and piston in the gas engine of internal-combustion engine or air compressor, existing gas seal ring constitutes by clamping a sheet negative and positive ring between two identical breach loops, wherein two opening loops are thinner, and sheet type negative and positive ring is thicker.Because the extensional motion that piston goes round and begins again in cylinder, the mutual wearing and tearing between compression ring and the cylinder wall enlarge the inside and outside footpath of loop harmonizing yinyang ring and breach gap gradually.Certainly, the oil seal ring on the piston also is like this.Like this, when aspirating stroke, because the air pressure of firing chamber is lower than barometric pressure, add the inertia of lubricating oil supply system, breach after machine oil just enlarges through oil ring, compression ring wearing and tearing, flow into combustor, machine oil is without crossing high-pressure fog, just irregular collision, boiling take place in the high-temperature gas with acting, make combustion process intrinsic in the machine slow, obviously, the not thorough finishing combustion of machine oil, become gas discharges such as carbon monoxide, serious environment pollution.For example homemade " 3:110 " type internal-combustion engine, new engine entry into service 12 hours, Oil Consumption is 0.5 kilogram, day by day be increased to later on 15 kilograms/more than 12 hours, and start more and more difficultly, and power reduces greatly, and fuel consumption, CO (carbon monoxide converter) emission all increase.
The model utility content
The utility model is in order to overcome the defective of prior art, and a kind of little, internal-combustion engine of long service life of wearing and tearing, air compressor piston ring are provided.
The utility model internal-combustion engine, air compressor piston ring comprise the loop that inside and outside footpath is equipped with pistion recess and cylinder bore diameter respectively; Wherein the left opening end at loop cuts out 1/3 of annulus width, and the ladder that cuts out 2/3, two correspondence of annulus width at the right opening end of loop overlaps equipped mutually; Be provided with the frame shape groove at left and right opening end, frame shape sheet pin and frame shape groove active mounting; Frame shape sheet pin external diameter is identical with the loop external diameter, and central angle is 90 °, and the thickness of frame shape sheet pin is 2/3 of sheet ring thickness.
The utility model internal-combustion engine, air compressor piston ring, wherein the central depths of frame shape groove is 2/3 of a sheet ring width.
The utility model internal-combustion engine, air compressor piston ring, the length of the circumferencial direction of wherein left and right opening end cutouts are 8mm.
The utility model internal-combustion engine, air compressor piston ring, it is the composite structure that three rings of former cause are constituted, change the structure of a ring and a frame shape sheet pin into, and the lapping direction of ring breach has strengthened the intensity of ring by inside and outside footpath and axial direction perpendicular to ring.Frame shape sheet pin blocks the breach of loop, is expanded outwardly by loop self elastic force and clamps frame shape sheet pin, and both cooperatively interact, and overcome the defective of the gap enlargement that causes because of wearing and tearing, make the envelope gas of the gap portions of ring, oil sealing effect play constant effect.Simultaneously, two caudal horn ends of frame shape sheet pin also wear and tear with the groove that is equipped with thereupon and enlarge, two jiaos of ends form the fossa states, make because of dirts such as trickle steel cuttings that wearing and tearing produce, the dregs of fat to pile up the fossa place of filling up at two jiaos of ends, and it plays the effect of envelope gas, oil sealing equally.Like this, make internal-combustion engine or air compressor complete machine can save lubricant oil 85%, and, make complete machine fuel oil utilization ratio improve 9%.Thereby reduced the operating cost of complete machine, prolonged the working life of cylinder, piston.
