Abstract
A sealing system for a Gravity Power Plant having a shaft () with a shaft wall () and a piston () incorporates a seal assembly support base () anchored into the shaft wall and surrounding the piston. A seal mount has a radial flange () to anchor the seal mount to the support base () and a vertical flange () extending from an inner circumference of the radial flange. A seal assembly () circumferentially contacting the piston, has a plurality of circumferentially spaced clamp assemblies () to engage the seal assembly to the vertical flange, the clamp assemblies having an open position releasing the seal assembly from the vertical flange and a closed position constraining the seal assembly on the vertical flange. For seismic isolation of the seal assembly the radial flange is supported on a lower bearing () supported on a top surface of the seal assembly support base proximate an inner surface. The radial flange () extends inward from the inner surface with the vertical flange spaced from the inner surface by a radial relief () within a gap between the seal assembly support base and the piston. An upper bearing is supported in engagement with a top surface () of the radial flange () of the seal mount ().
