ROTARY WORKING DEVICE HAVING PISTON-CYLINDER WITH CLOSED STRUCTURE

摘要

The present invention relates to a rotary working device having a closed structure, capable of collecting natural energy of various forms and artificial energy being wasted and converting the collected energy into mechanical energy or electrical energy, through the configuration of a cylinder engaged with a piston, and to an energy conversion device and a configuration for facilitating the driving of the device, the energy conversion device has: a plurality of compartment parts wherein at least one is a piston-cylinder type; a passageway through which a working fluid passes; and rotary working bodies such as a hydraulic motor and a turbine, wherein one overall closed structure is formed such that the entry/exit of a fluid is blocked to/from the outside.
