  • Method for flushing out a narrow gap
    Patent number: 4257819
    Abstract: Difficult flushing of a very narrow gap between a first member having a bore with a closed end and a second member inserted and fixed in the bore can be easily achieved by connecting the gap with a container filled with a pressurized flushing liquid and locally heating the closed end of the gap. Preferably, while locally heating the blocked end of the gap the pressure of the pressurized liquid is reduced to cause the liquid to boil, and if necessary, the pressurizing and pressure reduction are repeated to enhance the flushing effect.
