A bearing pressure system includes a bearing assembly having a first component movable against a second component and at least one accumulator in fluid communication with an interface between the first and second components, the at least one accumulator holding a pressurized fluid. A method includes providing a bearing pressure system having a fluid communicable between an accumulator and an interface between components movable relative to each other, providing an amount of pressurized fluid from the accumulator to the interface when the pressure of the fluid at the interface falls below a pressure range being maintained, and transferring an amount of the fluid from the interface to the accumulator when the pressure of the fluid at the interface rises above the pressure range being maintained.

Pressure system for bearing assembly and method of use

A failure protection apparatus including an air source providing air having an air pressure, a first valve in fluid communication with the air source permitting a control fluid to flow to a pressure control assembly when the air pressure is at least a minimum pressure and preventing flow of the control fluid to the assembly when the air pressure is below a minimum pressure, the assembly containing control fluid at a predetermined pressure that is maintained when the air pressure is below the minimum pressure, a second valve in communication with the air source permitting communication of air between an inlet and an outlet when the air pressure is below the minimum pressure, a third valve in communication with the air source, a pressure container in communication with the third valve outlet and having an outlet that feeds air to the second valve to actuate a warning device attached thereto.
