Abstract
A gland seal assembly is provided which utilizes a double oil flow in conjunction with two gland seal rings. One of the oil streams is passed through a gland seal ring in a radial direction into the clearance gap between that ring and a rotatable shaft. Another flow of oil is passed between that ring and another gland seal ring in such a way as to exert a force between the rings which pushes the two rings in opposing axial directions away from each other and toward axial faces of an angular groove in a gland seal bracket. By causing a force against the gland seal rings in axial opposing directions, the rings are moved towards the axial faces of an annular groove in such a way that gaps between the gland seal rings and the groove wall are reduced with a corresponding reduction in the non-functional flow of oil.
