Embodiment Construction
[0037] The present invention provides a kind of piston in view of the foregoing status of the prior art, which includes a piston body 6, see Figure 5-9 , the outer peripheral surface of the piston body 6 is provided with a groove, and the groove includes a first groove segment 8 and a second groove segment 9 . Wherein, the first slot section 8 is located on one side of the first central plane of the piston body, and the second slot section 9 is located on the other side of the first central plane. In particular, the area of the second groove segment 9 is larger than the area of the first groove segment 8 . Here, the area of the groove section may refer to the area defined by the outer edge of the groove on the outer peripheral surface of the piston body, or may refer to the projected area of the groove on the first central plane. In the present invention, the first center plane is a plane passing through the axis of the piston body 6 .
[0038] That is, the grooves ...
