Abstract: The nozzles include inlet ports circumferentially arranged into a group and an opening and closing valve disposed so as to be commonly functioned. This arrangement realizes a gas turbine with no deterioration of efficiency against fluctuation of gas inflow rate by only one heat-resistant moving component additionally installed. The variable nozzle number turbine according to this invention also realizes a turbine compressor with no surge limit when used as a regenerator. These turbines further realizes a small-sized gas turbine with improved fuel economy under partial load conditions and a turbocharger for regenerating electric power as well as improving efficiency of a displacement engine.

Abstract: A third motion transfer mechanism transfers valve actuation motion from a second motion source to a first engine valve. A motion decoupler is configured to selectively discontinue the transfer of motion from a first motion transfer mechanism to the first engine valve. Furthermore, a reset mechanism is configured to selectively discontinue, based on operation of a second motion transfer mechanism, the transfer of motion from the third motion transfer mechanism to the first engine valve. The third motion transfer mechanism may comprise a master piston and a slave piston in fluid communication with each other via a hydraulic circuit, the master piston being configured to receive motion from the second motion source and the slave piston being configured to transfer motion to the first engine valve.
