摘要： Manufacturing a porous component used as flow restrictor includes a metal injection molding process enhanced to obtain a component with open porosity homogeneously distributed. The flow restrictor includes at least one porous component having at least one restricting portion with some porosity dimensioned to regulate the flow of gas to an aerostatic bearing of a mechanical system, such as a hermetic compressor. Use and production of a porous component obtained by powder injection molding or powder injection molding of multi-material parts is also described, the porous component being a flow restrictor with a layer of dense material, with no open pores, on the outer surface parallel to the flow direction in which the flow through the porous component occurs, allowing it to be inserted into the bearing system without interfering with the porous structure of the core (dual porosity). Sealing existing between the porous component and its housing is described.
