Ejector-type jet pump has at least regions forming inner surfaces of jet housing, and inner and outer surfaces of jet itself, made from sintered material

摘要

The pump (ejector) consists of a jet housing (1) containing jet and a diffuser (3) connecting to the jet housing. At least the regions forming the inner surfaces (4) of the jet housing and the inner and outer surfaces (5, 6) of the jet itself are made from a sintered material produced by the techniques of powder metallurgy.
