  • Solution for controlling a turbo compressor
    Patent number: 9528526
    Abstract: An actuator includes at least one stage of turbo compressor, with an outlet for conveying gas compressed in the at least one stage of turbo compressor to at least one cooler, and a shaft for rotating the at least one stage of turbo compressor, for increasing the pressure of the gas to be supplied to the actuator. The actuator also includes a turbine and a control valve by means of which the flow of compressed gas produced by the turbo compressor to the turbine is arranged to be adjusted. A method for controlling the actuator, as well as a control system for the actuator are also described.

  • Method for securing the lubrication of bearings in a hermetic high-speed machine
    Patent number: 5329771
    Abstract: The present invention is directed to a method for operating a hermetic, small-size power plant in which a primary circulation is conducted in a main line connecting a high-speed machine including at least a turbine and a generator installed on a joint rotor, a vaporizer and a condenser. Fluid lubrication of bearings of the rotor during the continuing operation is effected by fluid medium passing through the condenser and along the main line of the primary circulation. The vaporizer is connected to the high-speed machine through medium flow paths defining a circulating medium circuit bypassing the condenser and at least partly bypassing the main line of the primary circulation to secure passage of circulating medium accumulated in the vaporizer for lubrication of the bearings of the rotor during stopping of the primary circulation.
