Abstract
The present invention relates to a kind of piston ring, including annular body, the end of body is provided with 45 ° of angular cut, and the axial height of body is equal with radial thickness.The beneficial effects of the invention are as follows：Port contact is close, and leakage rate is few, and service efficiency is high.
Description
Technical field
The present invention relates to a kind of piston ring.
Background technology
Piston ring is part important in piston, and its performance often directly affects the situation of piston.Conventional piston ring
Ends contact is not close, with the increase worn in use, easily causes leakage rate original bigger, reduces capacity.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, the present invention provides a kind of piston ring.
A technical scheme is used by the present invention solves its technical problem：A kind of piston ring, including annular body, this
The end of body is provided with 45 ° of angular cut, and the axial height of body is equal with radial thickness.
Further, the material of body is polytetrafluoroethylene (PTFE).
The beneficial effects of the invention are as follows：Port contact is close, and leakage rate is few, and service efficiency is high.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Embodiment
Presently in connection with specific embodiment, the invention will be further described, following examples be intended to illustrate invention rather than
Limitation of the invention further.
A kind of piston ring as shown in Figure 1, including annular body, the end of body are provided with 45 ° of angular cut, the axle of body
It is equal with radial thickness to height.
The material of body is polytetrafluoroethylene (PTFE).
The axial height increase of piston ring is advantageous to increase the intensity of ring, reduces the cold flow properties of ring, increases the elastic force of ring, easily
In overcoming the friction between its end face and piston ring groove.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
Claims (2)
1. a kind of piston ring, including annular body, it is characterized in that：The end of described body is provided with 45 ° of angular cut, body
Axial height is equal with radial thickness.
2. piston ring according to claim 1, it is characterized in that：The material of described body is polytetrafluoroethylene (PTFE).
