FLUID MACHINE

摘要

PROBLEM TO BE SOLVED: To provided a fluid machine provided with both of a pump mode compressing and delivering fluid and a motor mode converting fluid pressure at a time of expansion to kinetic energy and outputting mechanical energy, capable of satisfying capacity at a time of pump mode execution and improving efficiency at a time of motor mode execution. SOLUTION: This fluid machine includes a pump motor mechanism 100 provided with both of the pump mode receiving rotation force from a drive source 20 and compressing and delivering fluid and a motor mode converting fluid pressure at a time of expansion to kinetic energy and outputting mechanical energy. A transmission mechanism 400 increasing rotation speed of rotation force from the drive source 20 and transmitting the same to the pump motor mechanism 100 before execution of the pump mode is provided.
