摘要： A compressor wheel for a compressor of a turbocharger has a hub (16) and a multiplicity of blades (12) on the hub (16). In intermediate spaces of the multiplicity of blades (12), a channel is in each case formed between a suction side (24) and a pressure side (26). The channel guides fluid that flows in axially in relation to a rotation axis (22) radially or radially-axially outward. The hub (16) in relation to the rotation axis (22) in at least one channel is contoured with a rotationally symmetrical portion (18′) and a non-rotationally symmetrical portion (18). The non-rotationally symmetrical portion (18) is formed by radii that are variable in the flow direction, and a transition region (28) between the hub (16) and the blade (12) adjoins the non-rotationally symmetrical portion (18).

摘要： A rotor having spiral pathways to enable liquid or gas to flow from a center to an exterior thereof. The spiral pathways increases power generated (input force) as liquid/gas travels therethrough. The spiral pathway rotor includes an inner disk and an outer disk. Inner disk includes a central opening for receiving the liquid/gas and is connected to a plurality of pathways that extend toward an outer edge in a spiral manner. Nozzles may be utilized to expel the liquid/gas. Outer disk includes an open interior having a plurality of teeth formed on an interior surface. The teeth are configured to receive the liquid/gas expelled from inner disk which causes the rotor to rotate and thus increases the input force thereof. The input force is amplified to an output force on a shaft connected thereto.

摘要： A head-mountable flow generator is configured to deliver a flow of breathable gas at a continuously positive pressure with respect to ambient air pressure to a patient interface in communication with an entrance to a patient's airways including at least an entrance of the patient's nares, while the patient is sleeping, to ameliorate sleep disordered breathing. The flow generator includes a motor, an impeller assembly and housing that encases the motor and the impeller assembly. The housing is configured to be mounted on the patient's head and comprises an inlet to receive the flow of breathable gas and a pair of opposing outlets to deliver the flow of breathable gas. In addition, the impeller assembly is configured to pressurize the flow of breathable gas received from the inlet, and the housing is configured to convey the pressurized flow of breathable gas through both outlets.

摘要： A rotary roof vent consisting of a base, an impeller, an axle holding/supporting a rotating rim with blades and a cover. The impeller is solid and formed as a rim with stiffeners, and the blades are located at the outside edges of the rim. A hollow sleeve is positioned at the central part for receiving an axle. The blades are formed having a convex shape. A protrusion positioned at an acute angle disposed at the end of each blade. Another protrusion is disposed at obtuse angle to the blade and is positioned closer to the center. The blades are inserted into the impeller by 20% in relation to the base diameter. The impeller stiffeners having arch shaped configuration are adapted to follow a contour of the blades.

摘要： A compressor control device includes: an inlet guide vane disposed in an inlet section of a compressor; a variable stationary blade disposed downstream of the inlet guide vane; a rotor blade disposed between the inlet guide vane and the variable stationary blade; a first actuator for adjusting a first opening degree of the inlet guide vane; a second actuator for adjusting a second opening degree of the variable stationary blade; a compressor inlet temperature detection part for detecting a compressor inlet temperature in the inlet section; and a control part for controlling the first actuator and the second actuator. The control part controls the first actuator and the second actuator such that an opening degree ratio of the first opening degree to the second opening degree increases as the compressor inlet temperature decreases, if the compressor inlet temperature is less than a threshold.

摘要： A counter-rotating supersonic compressor. A first subsonic rotor includes a plurality of unshrouded impulse rotor blades operating at sub-sonic conditions. A second, supersonic rotor includes a fixed second rotor portion and an adjustable second rotor portion. The fixed second rotor portion includes a plurality of supersonic passageways having converging-diverging sidewalls, and internal boundary layer bleed passageways. The adjustable second rotor portion includes a plurality of centerbodies which are disposed in the supersonic passageways. Helical movement (circumferential and axial) movement of the adjustable second rotor portion with respect to the fixed second rotor portion enables upstream and downstream movement of the centerbodies in the supersonic passageways. This movement facilitates ease of supersonic startup, and automatic adjustment for changes in operation conditions, such as pressure, temperature, or mass flow rate of a working fluid such as carbon dioxide.

摘要： A compressor wheel is provided for an exhaust-gas turbocharger of an internal combustion engine. The compressor wheel has a hub, which extends around a central axis of the compressor wheel, and compressor wheel blades, which are connected to the hub and the blade leading edges of which extend in a radial direction and have a hub-side end region and an end region that is radially remote from the hub. The blade leading edges are blunt in their end region that is radially remote from the hub.
