Fluid separator for a displacement machine and a method for separating lubricant and working fluid in a displacement machine
A displacement machine is for acting on a working fluid and is provided with a lubricant and working fluid separator. The fluid separator has a separator volume constrained by a shielding member, a first fluid channel providing fluid communication between a first and second inner volumes and the separator volume, a second fluid channel providing fluid communication between the separator volume and a working fluid return volume. The fluid separator, the first fluid channel and the second fluid channel are fully contained within a full volume of the displacement machine. A method is for separating lubricant and working fluid in a displacement machine.
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.
