PISTON SEAL AND METHOD OF REDUCING FRICTIONAL FORCES OF A PISTON SEAL |
| 摘要 |
A piston seal includes an inner surface configured to extend proximate a perimeter of a piston. Also included is an outer surface disposed proximate a chamber wall, wherein the chamber wall defines a chamber for the piston and the piston seal to translate within. Further included is a first axial side exposed to a first pressure portion of the chamber. Yet further included is a second axial side exposed to a second pressure portion of the chamber. Also included is at least one pressure differential reducing hole extending radially through the piston seal from the inner surface to the outer surface. |

1. A piston seal comprising:
an inner surface configured to extend proximate a perimeter of a piston; an outer surface disposed proximate a chamber wall, wherein the chamber wall defines a chamber for the piston and the piston seal to translate within; a first axial side exposed to a first pressure portion of the chamber; a second axial side exposed to a second pressure portion of the chamber; and at least one pressure differential reducing hole extending radially through the piston seal from the inner surface to the outer surface. |
