Abstract: 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.

Abstract: The present invention relates to an anti-shake flow-limiting cutoff valve, comprising a flow stop valve, a cutoff valve and a check structure. Said flow stop valve comprises a valve body, a valve seat, a piston and a biasing component. The check structure is arranged downstream said flow stop valve to prevent fluid from flowing back. In case of a sudden excessive water flow, the flow stop valve is closed under impact of excessive water pressure to block the water flow. At this time, since the liquid flow in the pipeline is suddenly blocked, the liquid flow remaining in a pipeline downstream the flow stop valve tends to form a reverse flow to impact the flow stop valve, thus shaking the flow stop valve, which may further lead to insufficient close or damage of the flow stop valve.

Abstract: The invention relates to a device for using flow energy, in particular wind energy, comprising elements (2) that have incident-flow surfaces (1) and that are guided so as to circulate on a track at a distance to each other, wherein a rotational axis about which the elements (2) move is arranged perpendicularly to the flow direction, and comprising an apparatus (5) for transmitting the flow energy captured using the elements (2) to a generator (15). According to the invention, the apparatus (5) and the elements (2) are connected to each other in such a way that forces acting tangentially to the track (3) are transmitted and forces acting in other directions are not transmitted or are transmitted only in an attenuated manner.
