Hydraulic pressure transducer and hydraulic system

摘要

A power station system operable to generate energy and comprising a heat engine system and a hydraulic system connected thereto. The heat engine system comprises n number of energy cells, wherein n is an integer, and n≧2, a heat source connected to the energy cells, and a cooler means connected to the energy cells. Each energy cell is operable to generate a pressurized fluid when a phase change material (PCM), comprised in each energy cell, changes from solid phase to liquid phase, and the energy cells are operable between a first phase, and a second phase. During the first phase, a first n/2 of the energy cells produce pressurized fluid, and a second n/2 of the energy cells are cooling down, and during the second phase, the first n/2 of the energy cells are cooling down, and a second n/2 of the energy cells produce pressurized fluid. The hydraulic system comprises a pressure transducer, and a hydraulic motor connected thereto, and is operable to generate a constant rotation speed.
