摘要： According to a first aspect of the invention there is provided a thermodynamic machine operating according to the Brayton cycle and including a closed loop fluid circuit for circulating working fluid. A fluid compressor (8) and a fluid expander (10) are independently controllable variable positive displacement machines. The variable positive displacement machines incorporate working chambers of cyclically varying volume, the net fluid displacement of each working chamber being selectable on a cycle by cycle basis. The compressor and expander axles are linked and the compressor and expander can be controlled to independently vary the displacement of the compressor, the displacement of the expander and the net torque exerted on the axle. The machine works efficiently with a wide range of heat source and heat sink temperatures and can respond to varying power demands, including transient changes to power demand.

摘要： A valvetrain control arrangement for an internal combustion engine. A fluid-working machine (1) has working chambers (3) of cyclically varying volume, each connected to a piston actuator (4) which is capable of moving an intake or exhaust valve in the internal combustion engine.

摘要： A fluid-working machine has a working chamber of cyclically varying volume, high and low pressure manifolds, and high and low pressure valves for regulating the flow of fluid between the working chamber and the high and low pressure manifolds respectively. A controller actively controls at least one said valve to determine the net displacement of working fluid of the working chamber on a cycle by cycle basis. At least one said valve is a variable timing valve and the controller causes the valve to open or close at a time determined taking into account one or more properties of the performance of the fluid working machine measured during an earlier cycle of working chamber volume.
