摘要

A stationary assembly for use in a gas or liquid seal for sealing an interface between a machine body and a rotatable shaft. The stationary assembly (10) includes an annular seal ring (11) attached to the machine body and surrounding the shaft (13). An annular seal ring housing (16) secures the seal ring (11) and includes a plurality of bores (20). Each bore retains a spring (22). A circumferentially flexible "O" ring holder (24) receives the springs. The "O" ring holder (24) presses an "O" ring (26) against a balance diameter (31) surrounding the shaft (13) and the seal ring (11) to provide a seal. The "O" ring holder (24) includes a plurality of slots (30) formed therein and arranged to provide the circumferential flexibility. <IMAGE>
