Abstract
The present invention provides a kind of high-sealing piston compression ring, on the piston body in compression, is provided with two seal gas rings being crisscross arranged, inside the open at one end of seal gas ring, it is provided with projection, this projection is connected with compression ring opening, correspond to inside seal gas ring and also be provided with another projection on above-mentioned projection inwall；In the bottom land of compression, it is provided with the groove matching with above-mentioned projection, so, be arranged at along with two seal gas rings in compression, because the effect of projection and groove is it is ensured that the positioning of seal gas ring, make a seal gas ring central lug overlapping with the plane of next root seal gas ring opening projection；Block collaborating of breach outside two compression rings；The projection of next root seal gas ring opening inner side, has blocked seal gas ring collaborating by Inside To Outside；So either axially, radial direction or circumference, all in sealing state, improve cylinder pressure, reduce fuel consumption, disposal of pollutants；Achieve the maintenance-free of cylinder, piston, piston ring.
Description
Technical field
The present invention relates to a kind of piston ring, it is a kind of high-sealing piston compression ring.
Background technology
The reciprocating piston that all types of internal combustion engines, compressor etc. are adopted at present, oil ring groove and compression have been positioned apart from its piston body, it is respectively arranged with the single high sealing gas ring of single oil ring and opening in oil ring groove and compression, the opening of the seal gas ring in twice compression is in shift to install.But the opening of the compression ring in the protruding parts through adjacent compression for the opening of upper track seal gas ring and lower road compression is in still opening-wide state, and with multiple reciprocal operation, the opening of seal gas ring, change from small to big, dislocation gas leakage is more serious, its poor sealing performance, service life is short, piston and compression ring need to often be changed, useless work when useless, work efficiency is extremely low, also once this was made improvements for this applicant, and applied for Patent No. 00220443, 6, a kind of utility model patent of high-sealing piston, it is in compression, it is provided with the compression ring of two openings, and it is provided with the ring-type lining spring of opening between compression ring and compression, the opening of the opening of lining spring and two compression rings is mutually for 120 °；It passes through to serve as a contrast the own tension effect of the opening offset of spring compression ring and lining spring, thus improve the sealing property of piston；However, in practical work process, due to the percussion suffered by piston, serving as a contrast spring and compression ring inevitably still produce and channels bit, so that lining spring and the opening of two compression rings is overlapped, and cannot reset on the spot after overlap, lead to its sealing property to be lost.
Content of the invention
In place of overcoming the deficiencies in the prior art, the mesh ground of the present invention be to provide a kind of reasonable in design, exempt from gas leakage, the seal gas ring of service life speciality, thoroughly avoid seal gas ring in annular groove radially, axially, circumference and opening at gas leakage, improve cylinder pressure, reduce fuel consumption and disposal of pollutants.
For realizing above-mentioned mesh ground, the present invention adopts the following technical scheme that：Including piston body, piston body is provided with compression and oil ring groove, is provided with oil ring in oil ring groove；With along with compression, be provided with two opening seal gas rings being crisscross arranged it is characterised in that：The opening inner side of seal gas ring is provided with projection, and one end of this projection is matched with the open at one end of compression ring；Correspond to the inwall of above-mentioned projection in the inner side of seal gas ring, also be provided with same another projection；On the piston body, the bottom land of compression is provided with two grooves matching with above-mentioned two projections；So, be arranged at along with two high sealing gas rings in compression, effect due to projection and groove, ensure that the positioning of seal gas ring, make it operationally will not produce to circumferentially rotate and channel bit, meanwhile, also ensure that overlapping of the projection of a high sealing gas ring center and opening inner side and next root high sealing gas ring opening and central lug plane, the projection of seal gas ring opening inner side closes by the gas leakage of seal gas ring Inside To Outside it is ensured that good sealing property.
The beneficial effects of the present invention is：Because the opening inner side in seal gas ring is additionally arranged projection, correspond on the inwall of above-mentioned projection in the inner side of seal gas ring, it also is provided with same another projection, and the bottom land in compression is provided with the groove matching with above-mentioned two projections, so, in pistons work, the center of a upper compression ring and the projection of opening inner side, it is close to the opening of next root high sealing gas ring and the projection plane at center in the presence of gas, the outside breach having blocked two seal gas rings is collaborated, projection due to next root seal gas ring opening inner side is close to opening inner side, closure seal gas ring is in compression by collaborate (gas come in along the gap between the top of a upper compression ring and compression) of Inside To Outside；Greatly improve the sealing property of cylinder, reduce fuel consumption, the particularly discharge of pollution it is achieved that cylinder, piston, the maintenance-free of piston ring.
Brief description
Fig. 1 is the schematic view of the mounting position of inventive piston ring；
Fig. 2,3,4 are the structural representation of inventive piston ring.
In figure：1st, 6 is high-sealing piston compression ring, and 11,12,62 is projection, and 2 is oil ring, and 3 is oilhole, and 4 is piston pin hole, and 5 is piston body.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is made to say in detail further.
High-sealing piston compression ring of the present invention, its piston body 5 is from top to bottom provided with compression and oil ring groove；Being provided with two openings in compression is in the seal gas ring 6,1 being crisscross arranged, and the opening of two seal gas rings 6,1 is in 180 °；It is provided with projection 11 in the opening inner side of seal gas ring 1, one end of this projection 11 is connected with opening；The inwall corresponding to above-mentioned projection 11 for seal gas ring 1 inner side also is provided with another projection 12；It is provided with the groove matching with above-mentioned projection 11,12 in the bottom land of compression.
