Abstract

The utility model relates to an energy saving piston ring, in particular to an energy conservation gas engine component, which like well known piston ring, consists of a pneumatic ring, a seal ring and an oil ring, wherein, the ends of the seal ring of the energy conservation piston change the traditional method that the end of the well known piston seal ring is vertically connected to a plane, adds rotation face connection ends which adopt the axis of the piston ring as the axis and the rotation face of the machine is connected to the lower side of a cylinder jacket and a piston ring groove, thus in the exergonic stroke, one end of the ring tightly presses the seal ring at the other end, thereby avoiding leaking and achieving the aim of energy conservation.

Description

The energy-saving piston ring

The energy-saving piston ring is the parts of fuel oil machinery

After existing piston ring uses a period of time, because the wearing and tearing of the inwall of the outer rim of piston ring and cylinder sleeve, cause gap, the joint change of weather of piston ring and leak gas, the loss part energy in order not lose this part energy, has designed the energy-saving piston ring.

The purpose of this utility model provides a kind of energy-saving piston ring, and it both makes cylinder sleeve and piston ring or wherein one is having under the situation of wearing and tearing, also can make internal-combustion engine compression and expansion stroke in can be and off-energy from gas leakage between the two ends of ring.

The purpose of this utility model is achieved in that the energy-saving piston ring is made up of compression ring, seal ring and oil ring.Being provided with same is the surface of revolution of the correspondence that can make the two ends connection of axle at those seal ring two ends, road of contiguous oil ring with the energy-saving piston annulate shaft, and after the energy-saving piston ring is loaded into internal-combustion engine, two surface of revolution can overlap, and the surface of revolution that overlaps connects the side that cylinder sleeve and piston ring groove close on oil ring.When the cylinder liner internal diameter increases because of wearing and tearing, the diameter of seal ring also increases thereupon, but still has the partial rotation face to coincide together.In compression and expansion stroke, an end is pressed on the other end, and two ends all are pressed on the side of cylinder sleeve and piston ring groove, the slit that can not leak gas between two ends, thus avoided because of the gas leakage off-energy.

Adopt such scheme, only changed the end structure of ring together, just can reduce energy loss, and using known piston ring, cylinder sleeve is changed the energy-saving piston ring because of under the out of use situation of wearing and tearing, cylinder sleeve can continue to use, thereby has prolonged the working life of cylinder sleeve.

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is: the end view of apparatus of the seal ring of energy-saving piston ring.

Among the figure: be the surface of revolution of axle 1, with the sealing annulate shaft; 2, bottom surface; 3, side; 4, with the seal shaft be the surface of revolution of axle; 5, shaft section; 6, shaft section; 7, shaft section; 8, shaft section;

In the drawings, there is a wedge end of the outer bottom of the right-hand member of seal ring, this wedge is to be the part of the solid of rotation of axle with the energy-saving piston annulate shaft, in three surface of revolution that its head and the tail connect successively, one side for the surface of revolution (1) that can make two ends and connect in addition the two sides respectively on bottom surface (2) and side (3).One side on side (3), its height be preferably side (3) high 3/4, the one side on bottom surface (2), it is wide be preferably bottom surface (2) wide 4/5.The radian of the camber line on this wedge is preferably 5 degree.There are a same surface of revolution (4) corresponding with right-hand member and the same shaft section (7,8) corresponding with right-hand member shaft section (5,6) in the outer bottom of left end because of having lacked a wedge identical with right-hand member.

Claims

1. energy-saving piston ring, it is made up of compression ring, seal ring and oil ring, it is characterized in that: it is the surface of revolution that can make the correspondence that two ends connect of axle with the energy-saving piston annulate shaft that the two ends of seal ring have same; After the energy-saving piston ring was loaded into internal-combustion engine, the surface of revolution at two ends can overlap, and the surface of revolution that overlaps connects the side that cylinder sleeve and piston ring groove close on oil ring.

2. energy-saving piston ring according to claim 1, it is characterized in that: there is a wedge end of the outer bottom of seal ring one end, it is the surface of revolution that two ends are connected that a face is arranged on it, and there is a corresponding with it surface of revolution the outer bottom of the other end because of having lacked such wedge.
