Abstract
The utility model discloses a mono-directional sealed piston ring. The technical proposal of the utility model is that one end of the open piston ring is provided with a plane a and a plane b, while the other end is provided with a plane c and a plane d; the plane a is assorted with the plane c; and the plane b is assorted with the plane d. When the two ends are connected, the sealing along the axial direction and the longitudinal direction can be ensured. The utility model has the advantages of preventing the piston ring from decreasing the sealing performance after being abraded and bearing sudden pressure change thereby preventing the piston ring from producing component force along the diameter direction.
Description
The utility model relates to and a kind ofly is used on motor or the compressor using right angle face one-way sealing to reach gap piston ring, belongs to the piston ring technical field.
The joint of the opening end of existing piston ring is generally the plane type butt joint, because wearing and tearing increase also at any time variation of sealability.Therefore the existing piston ring is still not ideal enough in use.
The purpose of this utility model is: provide a kind of 1. piston ring still to guarantee one-way sealing after wearing and tearing; 2. can be competent at the very big and wear of piston-rings of air pressure or hydraulic pressure sudden change still uniformly right angle face one-way sealing reach gap piston ring.
The utility model is to constitute like this: process respectively at the two ends of open type piston ring a face and c face all with axial plane; Process b face and d face all with radial parallel.
Owing to adopted technique scheme, when a face that reaches gap piston ring when right angle face one-way sealing is subjected to mutation pressure, will not produce radial component, guarantee proper functioning, will remedy the gap that wearing and tearing bring owing to reach the existence of actinal surface.
Accompanying drawing is the novel structural representation of this reality.
Embodiment of the present utility model: body material gets final product with milling machine processing with the Manufacturing material of used piston ring, end shape.
Claims (2)
1. a right angle face one-way sealing reaches gap piston ring, and it comprises open type piston ring body, it is characterized in that: with behind a face ⊥ b face and the c face ⊥ d face, fit system reaches and connects from the radial direction at the opening two ends.
2. right angle according to claim 1 face one-way sealing reaches gap piston ring, and it is characterized in that: radial sealing surfaces is in the annular groove of piston.
