1. A fluid machine comprising:
- a housing;
a shaft supported on the housing, wherein the shaft is capable of being rotated by a driving force from a driving source;
an expansion-and-compressor device housed in the housing, the expansion-and-compressor device being capable of operating as a compressor device in a pump mode operation in which the expansion-and-compressor device is rotated by the driving force from the driving source via the shaft to compress working fluid, and of operating as an expansion device in a motor mode operation in which fluid pressure of the working fluid is converted into kinetic energy; and
a transmission device housed in the housing and located between the shaft and the expansion-and-compressor device, for transmitting rotation from the shaft to the expansion-and-compressor device, the transmission device being capable of increasing the rotational speed of the expansion-and-compressor device to be transmitted from the shaft to the expansion-and-compressor device, when the expansion-and-compressor device is operated in the pump mode operation.

Abstract
An expansion-and-compressor device of a fluid machine has a pump mode operation in which the expansion-and-compressor device is rotated by a driving force from a driving source to compress working fluid, and a motor mode operation in which the fluid pressure is converted into energy of movement to output kinetic energy. The fluid machine further has a transmission device for transmitting the driving force from the driving source with increased rotational speed, when the expansion-and-compressor device is operated in the pump mode operation.
