Abstract

PURPOSE: To absorb an imbalance between pressures of a water and an oil packed inside a high pressure water chamber and an oil chamber, respectively by enabling sliding friction of a lubricating oil contained piston secured to a piston rod as well as a main piston similarly secured to the piston rod.
CONSTITUTION: A lubricating oil containing piston 3 disposed at the site where a main piston 2 generates ultra-high pressures is so designed to make sliding friction in the both directions of the reciprocation of the main piston 2. And some part of a piston chamber 5 formed between the main piston 2 and the lubricating oil contained piston 3 is designed for a lubricating oil contained chamber 6. The other part of the piston chamber 5 is designed for a ultra-high pressure generating chamber 7.
