摘要： The invention relates to a river turbine (1) which comprises a fairing (3), a generator (22) that is driven by a first turbine wheel (5) and is housed in a volume formed by the fairing so as to generate an electric current when a first stream of water (9) sets the first turbine wheel in rotation, a passage for a second stream of water (10) that passes through the fairing (3) without passing through the first turbine wheel, and also a second turbine wheel (7) designed to exert a pumping action on this second stream of water (10). The passage of the second stream of water (10) is designed to cause the water to accelerate through the first turbine wheel.

摘要： Disclosed is an underwater turbine comprising a casing (3) in which a generator is arranged, and a shaft (5) that connects the generator to a turbine rotor (6). The shaft (5) extends at an angle from the horizontal and projects downward out of the casing through a shaft opening (15) in such a way that water is prevented from penetrating into the casing (3) by a gas volume compressed in the casing (3). At least one insulating element is provided across at least part of the inner surface.

摘要： Disclosed is an underwater turbine comprising a waterproof casing (3) in which a generator is arranged, and a shaft (5) that connects the generator to a turbine rotor (6). The shaft (5) extends at an angle from the horizontal and projects downward out of the casing through a shaft opening (12) in such a way that water is prevented from penetrating into the casing (3) by a gas volume compressed in the casing (3). The underwater turbine further comprises a gas inlet through which the casing (3) can be filled with a gas volume. The gas inlet is formed by a gas supply line (10) which is connected to a constant-pressure gas supply, in particular ambient air, and the inlet port (20) of which is arranged in the bottom region of the casing (3), above the shaft opening (12).
