| 摘要 |
A system, includes a piston. The piston has a first outer diameter and includes an annular ring groove that receives a ring. The annular ring groove is defined by a top surface, a bottom surface, and an inner surface that extends between the top surface and the bottom surface in an axial direction along a longitudinal axis of the piston. The inner surface has an inner diameter that is less than the outer diameter. The bottom surface has a recess that extends both in the axial direction and a radial direction relative to the longitudinal axis. |
