    摘要: Method of manufacturing a microscale nozzle, comprising the steps of forming a microscale channel in the top surface of a substrate, said microscale channel comprising an inlet end and a nozzle-end, depositing a nozzle-forming layer in a section of the microscale channel, and removing material from the substrate at the nozzle-end of the microscale channel to expose at least a portion of said nozzle-forming layer. The manufactured microscale nozzle may be used for transferring a liquid sample form a microchip fluidic system into an external analytical device.

    摘要: The invention relates to a method of controlling flow of liquids in a micro channel structure. It comprises providing in said micro channel structure plugs (34) of polymer material in said structure, said polymer material in a first state blocking said channel from liquid flow, and in a second state providing a free path-way (32) for liquid flow. Energy is selectively applied so as to cause said polymer to enter a desired one of said first or second states. It also relates to a micro channel valve system, comprising a plurality of such plugs (34). Additionally it comprises a chemical reactor, comprising a plurality of micro chambers interconnected by micro channels, having a valve system according to the invention.

    摘要: A turbocharger system for an internal combustion engine (10) having at least one exhaust line (15, 16) for evacuating exhaust gases from the combustion chamber (11) of the engine and at least one inlet line (12) for supplying air to the combustion chamber. A high-pressure turbine (17) interacts with a high-pressure compressor (19) and hereupon forms a high-pressure turbo unit (18) with a common rotation axis. A low-pressure turbine (21) interacts with a low-pressure compressor (23) and hereupon forms a low-pressure turbo unit (22) with a common rotation axis, for extracting energy from the exhaust flow of the engine and pressurizing the inlet air of the engine. The low-pressure turbine (21) is of the axial type. The high-pressure turbo unit and the low-pressure turbo unit are serially placed with the rotation axes essentially concentric and with the high-pressure turbine (17) and the low-pressure turbine (21) placed adjacent to each other and coupled together by an intermediate piece configured as a flow duct. This is arranged to allow a certain eccentricity between the two rotation axes. The low-pressure turbo unit (22) is attached to one part of the internal combustion engine (10), while the high-pressure turbo unit (18) is attached to another part of the engine (10).
