摘要： A method for forming a housing for a flow-conducting component includes forming at least two functional regions of the housing having different material properties using at least one of radiation-induced melting and solidification of a build material and a process gas jet. Each functional region of the housing may be generated from a different construction material, and at least one functional layer may be formed with a reduced weight structure such as a honeycomb structure.

摘要： A fan includes an inlet part disposed to form a fan inlet, a base disposed to form, together with the inlet part, a fan outlet, and a blade. The blade extends from the base to the inlet part, and includes a first guide surface having an inclination toward an outside of the fan in a radial direction of the fan which changes in a direction from the inlet part toward the base, and a second guide surface having an inclination toward the outside of the fan in the radial direction which changes in a direction from the base toward the inlet part.

摘要： A centrifugal compressor includes a compressor impeller attached to a rotary shaft and a housing accommodating the rotary shaft and the compressor impeller. The housing includes a suction portion formed upstream of the compressor impeller and a high pressure part formed on a rear face side of the compressor impeller and having a pressure higher than a pressure in the suction portion during rotation of the compressor impeller. The housing has a discharge passage formed for connecting the high pressure part to a low pressure part including the suction portion and a gas flow path upstream of the suction portion.

摘要： The catheter device comprises a drive shaft connected to a motor, and a rotor mounted on the drive shaft at the distal end section. The rotor has a frame structure which is formed by a screw-like boundary frame and rotor struts extending radially inwards from the boundary frame. The rotor struts are fastened to the drive shaft by their ends opposite the boundary frame. Between the boundary frame and the drive shaft extends an elastic covering. The frame structure is made of an elastic material such that, after forced compression, the rotor unfolds automatically.

摘要： Disclosed invention is an improved sealing system for axially split, centrifugal pumps. The improved sealing system eliminates the need for a gasket between casing halves. In the improved sealing system, a fluid tight seal is provided by an elastomeric cord positioned within a groove carried by the flange of at least one half of the axially split pump casing.

摘要： A support housing for a turbocharger is provided. The support housing may include an end wall with a first side and a second side, and a protrusion extending from the first side of the end wall in a first direction and configured to receive the turbocharger. The support housing may also include a plurality of side walls extending from the second side of the end wall in a second direction opposite the first direction. The plurality of side walls together with the end wall may form a generally hollow enclosure. The support housing may also include a first mounting flange disposed at distal edges of the plurality of side walls and configured to engage an engine, and a first center opening disposed in the end wall and passing from the first side to the second side.

摘要： A support housing is disclosed for use with a turbocharger. The support housing may have an end wall, a semi-cylindrical protrusion extending from the end wall in a first direction, and a plurality of side walls extending from the end wall in a second direction. The plurality of side walls together with the end wall may form a generally hollow enclosure. The support housing may also include a mounting flange disposed at distal edges of the plurality of side walls, and a center opening disposed in the end wall. The support housing may further include a collection cavity formed at a gravitationally lowest corner of the end wall below the center opening and substantially isolated from the enclosure formed by the plurality of side walls and the end wall, and a gutter passage formed in the end wall and extending from the center opening to the collection cavity.
