Abstract:
To prevent water or liquid containg the water from being polluted even if a static pressure feed screw machanism is used in the water or the liquid containing the water.
This static pressure feed screw mechanism is provided with a male screw 1 made of a material insoluble in water and nuts 2, 3 which are screw-fitted in the male screw 1 and are made of a material insoluble in water. This static pressure feed screw mechanism is immersed in water.
