Estimating the term…
There is described a regenerator (5) for an external heat engine, in particular for a Stirling engine, which is adapted for being mounted in the passageway for a working fluid moving from the hot side of the engine to a cold side of the engine and vice versa. The regenerator (5) is capable of receiving and temporarily storing heat, which is deposited by the working fluid when it passes through the regenerator (5), on its way from the hot side to the cold side of the engine, and of releasing heat to the working fluid again when it passes through the regenerator (5) on its way from the cold side to the hot side of the engine. The regenerator (5) comprises at least one through channel (50) which is tapered along an axial extension thereof from a hot side port to a cold side port of the through channel (50), so that the working fluid which flows along the through channel (50) is maintained under a generally constant pressure.
A regenerator for an external heat engine, in particular for a Stirling engine, which is adapted for being mounted in a conduit (4) for a working fluid (10) from a hot side (41) of the engine to a cold side (42) of the engine, and being capable of receiving and temporarily storing heat, which is deposited by the working fluid (10) when it passes through the regenerator (5) on its way from the hot side (41) to the cold side (42) of the engine, and being capable of releasing heat to the working fluid (10) again when it passes through the regenerator (5) on its way from the cold side (42) to the hot side (41) of the engine, characterized in that the regenerator comprises at least one through channel (50) which is tapered along a longitudinal axial extension thereof from a hot side port to a cold side port of the through channel (50) in such a manner, that the working fluid (10) flowing along the through channel (50) may be maintained under a generally constant pressure.
