An external-heat engine device working on a Rankine cycle, and preferably an organic Rankine cycle. The external-heat engine, which is designed to give operational advantages, includes a cylinder block, a top cover and a bottom tray with sealing surfaces arranged to be joined together and to rest against complementarily fitting covers, each sealing surface resting sealingly against only one opposite sealing surface.

A pulse-width-regulating valve is for the regulation of a fluid flow or a fluid pressure. The pulse-width-regulating valve comprises a cut-off valve connected in series with an inflow valve, at least one of the cut-off valve and the inflow valve being provided with an axially displaceable or rotatable valve element which has an opening position or a closing position at a distance from a starting position of the valve element. A method of operating a pulse-width-regulating valve comprises: regulating a valve gear device by a valve synchronizer, in accordance with at least two displacement curves; and by one or more valve actuators, displacing or rotating corresponding valve elements arranged in the pulse-width-regulating valve.

A thermal power station system has at least one heat engine connected to at least one work receiver. The heat engine is arranged to be able to utilize a working fluid alternating between liquid and gas phase. In the heat engine is arranged at least one heat exchanger in thermal contact with at least one expansion chamber. A method is for energy supply to a building or a vessel.

An inlet-valve arrangement is for an external-heat engine, which includes at least one working chamber, each one having a cooperating piston. The working chamber is supplied with a working fluid via at least one controlled poppet valve. The poppet valve is arranged to open in the opposite direction to the flow direction of the working fluid. The center axis of the poppet valve is arranged perpendicularly within a deviation of ±45 degrees relative to the center axis of the piston.

1. Abstract A method for heat exchanging in and work exchanging with a working fluid in a heat engine, or a heat pump if the method and its sub-processes are substantially reversed, is described, wherein a thermodynamic cycle for the working fluid is approximately described through the polytropic relation PV n = constant, where P is the pressure, V is the volume and n is the polytropic index of the working fluid with adiabatic index gamma (?), and wherein the engine consists of at least one working mechanism (1) provided with a first (150) and at least a second volume change chamber (151, 151'), the method comprising in sequence at least the following steps: a) in a first volume change process, to carry out a first polytropic volume change of the working fluid in a first volume change chamber (150) where n
