Hydraulic Pressure Transducer and Hydraulic System

摘要

The present invention relates to a pressure transducer for transforming a pressure of a fluid from one pressure level to another, comprising at least one pair of hydraulic rotating machines that are mutually mechanically interconnected in such a way that a first machine in a first pair of said at least one pair can run a second machine in the same first pair. Said first pair of machines is mounted in a first substantially closed room and each one of said first and second machines is in hydraulic connection with said first room. The present invention also relates to a hydraulic system for transferring hydraulic energy.
