ABSTRACT:
In hydrostatic pumps, motors and transmissions; faces, which slide and seal along adjacent faces, commonly have recesses for hydrostatic lubrication or for control of flow through ports.
The invention provides additional arrangements on such faces for the provision of additional functions, for example, for the control of hydrodynamic flow into spaces between faces, the control of an additional control flow through the faces and the sealing therof or it provides recesses or seal inserts of specific locations or configurations for the improvement of the efficiency of the faces or for assurance of additional actions by the faces.
