Abstract: An improved shaft seal assembly is disclosed having a stator including a main body and axial and radial projections therefrom. The rotor is radially extended and encompasses the axial and radial projections from said stator. The passageway formed between the radial projection of the stator and the rotor results in an axial passageway having its opening facing rearwardly from the rotor and away from the source of impinging coolant and/or contaminant. The dimension of interface gap between the rotor and the radial projection from the stator, which the access to the shaft of any impinging material, is fixed at a predetermined value and does not vary with the relative movement between the rotor and the stator. The novel seal assembly of this invention thus provides improved rejection or warding off of contaminates from ingress into the labyrinths and ultimately restrained from attacking the bearing environment.

Abstract: A brush seal designed for use between regions of high pressure differential and in an environment in which there is disturbed flow has a bristle pack sub-divided into a plurality of bristle pack regions with a leaky diaphragm between each region. The brush seal may comprise an assembly of individual seals with diaphragms between them or a single bristle pack which is sub-divided by at least one internal diaphragm. The diaphragms are preferably compliant and designed to allow a predetermined leakage flow between bristle regions. The leakage flow has several functions: it causes the pressure differential across the whole seal assembly to be more evenly distributed, and by providing an amount of flow in each pack this acts to calm the bristles thus helping to ensure each bristle region effectively contributes to the seal performance.
