Document Type and Number:
Japanese Patent JPH10513536
Kind Code:
A
Abstract:
A hydrostatic seal is provided having control of sealing surface taper and cavitation reduction structure between the sealing surfaces. Control of sealing surfaces taper is provided through one or more relief recesses in the seal wall to which flexing forces are applied by fluid pressure and temperature to reduce the effects of seal rigidity on the parallel relationship between the sealing surfaces. The cavitation reduction structure includes inclination of the channels leading to the sealing surface recesses in the direction of relative movement of the fluid between the sealing surfaces. Enlarged vortex chambers are disposed at the outlet of those channels within the recesses to isolate fluid vapor bubbles from the recess walls.\!
