Disclosed is a scroll compressor including stationary and movable scroll members engaged with each other. The stationary scroll member defines first and second air inlets and first and second air outlets. A first compression path is formed between the first air inlet outlet, and a second compression path is formed between the second air inlet outlet. The scroll compressor further includes a bypass passage for selectively communicating at least one of the first and second compression paths with a suction pressure area of the compressor. First and second back pressure cavities are formed on a side of the stationary scroll member facing away from the movable scroll member. The first back pressure cavity is in communication with the first compression path by means of a first back pressure passage. The second back pressure cavity is in communication with the second compression path by means of a second back pressure passage.

A radial compressor for an exhaust gas turbocharger may include a compressor housing in which a flow channel is arranged, a compressor wheel arranged in the flow channel, a device influencing a characteristic field, and a discharge channel. The flow channel may delimit a flow path of air through the radial compressor. The flow channel may have a suction section via which the compressor wheel sucks in air. The compressor housing may have a circumferential section circumferentially surrounding the compressor wheel in which a spiral channel of the flow channel may be arranged via which air compressed by the compressor wheel flows out. The device may include a cavity fluidically connected to the suction section. The discharge channel may be arranged in the compressor housing feeding, via an inlet mouth point, into the cavity and extending to an outlet mouth point fluidically connecting the cavity to the spiral channel.

A cooling system for providing streamlined airflow is provided. The system includes a fan assembly that includes an inlet side and an outlet side. The fan assembly also includes an inlet fan guard connector located at the inlet side of the fan assembly and an outlet fan guard connector located at the outlet side of the fan assembly. The fan assembly also includes a lever housings located between the inlet fan guard connector and the outlet fan guard connector and a slots oriented between the lever housings and the inlet fan guard connector and the outlet fan guard connector, the plurality of slots configured to secure an additional modular component.

A floating body for tidal current power generation of the present invention comprises: a power generation unit comprising a water wheel and a power generator connected to the water wheel; and a body part provided with tidal current inlet and outlet paths having a cross-sectional area that is gradually reduced from the front and rear surfaces thereof toward the water wheel. According to the present invention, a plurality of floating bodies for tidal current power generation are disposed in parallel so that the longitudinal direction of the tidal current inlet and outlet paths coincides with the direction of the tidal current in a terrain such as a strait with a narrow width. In addition, provided is a power generation method which is a method for adjusting the draft of a floating body for tidal current power generation depending on the flow velocity of the tidal current, thereby smoothly performing power generation even when the flow velocity of the tidal current becomes slower as tidal stand nears.
