Abstract
The utility model relates to an osculation type piston ring, which comprises an osculation piston ring. The utility model is characterized in that one end of the osculation piston ring is provided with a radial step of which the upper side is provided with adjacent front axial step and rear axial step, and the other end is provided with a radical step and two axial steps which are respectively corresponding to the end in the way of anastomosis. The utility model changes the structure of the traditional piston ring, eliminates the end gap of the piston ring, enhances the tightness of the piston ring, stops the problem of oil pumping and gas blowby of the engine, enhances the engine power, prolongs the service life and reduces the exhaust pollution.
Description
The utility model relates to a kind of rhynchostome type piston ring, belongs to the technical field of piston ring.
The conventional piston ring is under engine condition, because the wearing and tearing of piston ring and cylinder wall, the collar extension end gap is increased, and pressurized gas and outburst gas will be scurried into crankcase from collar extension, lubricant oil also can be scurried into the firing chamber from collar extension simultaneously, thereby engine compression ratio is reduced, and output power reduces, and lubricant oil increases, reduce working life, and every index such as exhaust pollution increase reduces.This all is because due to the piston ring side clearance increase.Therefore the structure shape that must improve piston ring just can overcome above-mentioned shortcoming.
The purpose of this utility model provides a kind of avoiding and scurries oil from the piston ring side clearance gas blowby, thereby improves the power and the rotating speed of motor, reduces oil consumption and exhaust pollution, prolongs motor a kind of rhynchostome type piston ring in working life.
Task of the present utility model is finished like this, it comprises the rhynchostome piston ring, it is characterized in that: an end of rhynchostome piston ring has a step radially, and former and later two adjacent axial step are radially arranged above the step, corresponding radially step and two axial step that the other end has and this end coincide respectively.
The utility model is compared with conventional art, changed the structure of conventional piston ring, eliminated the end gap of piston ring, has conspicuous advantage: the sealing that has strengthened piston ring, stop motor and scurried the problem of oily gas blowby, improve engine power, prolonged working life, reduced exhaust pollution etc.
Fig. 1 is the utility model structural representation.
Fig. 2 is an identical knot mouth structure schematic representation of the present utility model.
Drawing explanation: 1. axial step a 2. axial step faces 3. step surface 4. axial step b 5. axial step 6. step radially radially
Describe embodiment in detail in conjunction with above accompanying drawing, one end of rhynchostome type piston ring has a step 6 radially, adjacent former and later two axial step b4 and axial step 5 are radially arranged above the step 6, and the other end has and corresponding respectively two the identical axial step a1 of each step of this end, axial step face 2 and step surface 3 radially.The target axial step a1 of institute is corresponding with the matching surface of axial step b4 among the figure, and axial step face 2 is corresponding with axial step 5 matching surfaces, and radially step surface 3 is corresponding with the matching surface of step 6 radially.This identical structure can make piston ring seal fully, is contained in and just can forms a no end gap rhynchostome type piston ring in the motor.
