Abstract (en)
[origin: WO9917000A1] The invention relates to a component (1), especially for the shaft seal (9) of a fan, pump or compressor (11), made from a first cast metal material. The component (1) has at least one inner wall which is formed partially in a peripheral direction to the shaft axis, an outer wall (3) which is directed towards an outer area (16) and at least one fluid line (5,6) which is made of a second metal material. A fluid guideway (4A,4B) running at least partially in the direction of the periphery is also provided. Said guideway is flow-connected to the fluid line (5,6) and opens out towards the inner wall (2). The fluid line (5,6) is sealed into the first material and connects the inner wall to the outer area (16) by flow.
