Annular seal cavity throat bushing |
| 摘要 |
An annular seal cavity throat bushing includes an inner annular surface having a substantially latitudinal channel with the channel being provided with at least one orifice to allow fluid communication between the inside of the bushing and the outside of the bushing. The bushing is further provided with at least one groove extending substantially longitudinally from one end of the bushing to the channel. The groove has at least one tapered edge which increases the width of the groove along its length. |

1. An annular seal cavity throat bushing, comprising:
a bushing having a groove extending substantially longitudinally from one end of said bushing to a substantially latitudinal channel, the groove having at least one circumferentially tapered edge for increasing width of the groove along its length, the width of the groove increasing as the groove approaches the substantially latitudinal channel and depth of the groove increasing along a longitudinal length of the groove as the groove approaches the substantially latitudinal channel; and, an inner annular surface having the substantially latitudinal channel with the substantially latitudinal channel having an orifice for allowing fluid communication between an inner side of said bushing and an outer side of said bushing. |
