Abstract
A diaphragm has an annular groove formed of deep and shallow grooves with the deep groove opening into the shallow groove. A combination spill strip/brush seal is disposed in the groove. The brush seal comprises a pair of flexible bars secured to the proximal ends of the brush bristles by welding and is received in the shallow groove and a recess in an axial face of the spill strip. The spill strip has base portions extending into the deep groove. The combination spill strip/brush seal is secured in the annular groove by peening material of the diaphragm into the spill strip/brush seal combination. The brush seal may be used with different diameters of spill strips and diaphragm grooves.
