Title:
HIGH PRESSURE GENERATOR
Document Type and Number:
Japanese Patent JPS62132001
Kind Code:
A
Abstract:
PURPOSE:To enable the sliding surface of a booster to be certainly lubricated by driving the piston of a pressure transformer by means of primary liquid delivered in a boosted state from the booster in order to deliver secondary liquid supplied into the barrel of the pressure intensifier. CONSTITUTION:When a selector valve 7 is switched in order to supply pressure oil to a booster 1 by a pump 6, the operating fluid supplied in advance to a small chamber 4 from a primary liquid tank 5 is intensified in its pressure in order to be supplied to the primary liquid port 19 of a pressure transformer 13. The pressure transformer 13 delivers washing water as secondary liquid by the above mechanism. However, since pressure oil supplied to the booster 1 as well as the primary liquid delivered therefrom are operating fluids with high lubricity, even if the primary liquid leaks to a sliding surface by pressure differential due to pressure intensification, the sliding surface is enabled to be certainly lubricated.
