Abstract
The no-leakage piston ring consists of two identical piston ring sheets with an opening and one sealing boss in the width smaller than that of the opening. Two identical piston ring sheets are superposed through corresponding the openings and the sealing bosses to form one no-leakage piston ring. The no-leakage piston ring has effective sealing and simple structure, and is suitable for use in cylinder of internal combustion engine.
Description
Technical field
The invention belongs to internal-combustion engine technology, be specifically related to the piston ring structure that internal-combustion engine uses.
Background technique
The twice gas seal ring of traditional internal-combustion engine piston ring is installed separately on piston, reveals in order to reduce gap-clearance of piston rings as far as possible, requires the opening of two rings sheet to stagger mutually during the piston ring assembling.But in real work, piston ring can rotate, the opening of two rings sheet must be often to together, this will speed up gas leakage.Even two openings do not align, gas can be revealed too, and only leakage path is longer.
Summary of the invention
The present invention is directed to the above-mentioned defective that prior art exists, propose a kind of air leak proof piston ring.Adopt a kind of gap-clearance of piston rings interlocking structure, reach and simplify assembling, prevent the purpose of gas leakage.
Technological scheme of the present invention is as follows:
A kind of air leak proof piston ring, it is made up of the identical ring plate of two plate shapes size, it is characterized in that: the opposite anchor ring of the opening of every ring plate is provided with a locking seal boss, the two rings sheet is buckled together by the corresponding relation of opening and locking seal boss is folded mutually, forms no blowing piston ring.
The air leak proof piston ring that the present invention proposes solves piston ring by the locking seal boss and installs and need contraposition, and the problem that can't effectively seal is simple in structure, ingenious, effective, makes the cylinder of internal combustion engine sealing tighter, automotive performance better, more fuel-efficient.
Description of drawings
Fig. 1 is the floor map of air leak proof piston ring monolithic ring;
Fig. 2 is the side schematic view of air leak proof piston ring monolithic ring;
Fig. 3 is the structural representation after air leak proof piston ring assembles.
Specific embodiments
Referring to Fig. 1 and Fig. 2, this air leak proof piston ring is made up of the identical ring plate 1 of two plate shapes size, and the opposite anchor ring of the opening 2 of every ring plate 1 is provided with a locking seal boss 3, and the width of locking seal boss 3 is less than the width of ring plate opening 2.
When reality is used, two rings sheet 1 is buckled together with the corresponding relation of locking seal boss 3 is folded mutually by opening 2, form no blowing piston ring, as shown in Figure 3, the piston gas ring groove of the cylinder of packing into gets final product.Needn't remove to manage the gap-clearance of piston rings directionality problem again, assembling work labor intensity is also decreased.Simultaneously also need not process the twice compression on piston, only need together, only width increases some a little.
The width of locking seal boss 3 keeps certain elasticity less than the width of ring plate opening 2 after the cylinder so that piston ring is packed into.That is to say under the piston ring nature, when the two rings sheet fastens, between locking seal boss 3 and opening 2, should leave certain interval, compress when this gap is used to pack into cylinder and produce elastic force, what of this gap will be determined require the cylinder cylinder diameter and the material behavior of piston ring elasticity tension according to concrete motor.
Claims (2)
1. air leak proof piston ring, it is made up of the identical ring plate of two plate shapes size, it is characterized in that: the opposite anchor ring of the opening of every ring plate is provided with a locking seal boss, the two rings sheet is buckled together by the corresponding relation of opening and locking seal boss is folded mutually, forms no blowing piston ring.
2. air leak proof piston ring according to claim 1 is characterized in that: the width of locking seal boss is less than the width of ring plate opening.
