Title:
流体機械
Document Type and Number:
Japanese Patent JP4111901
Kind Code:
B2
Abstract:
A fluid machine for a gas compression refrigerating system comprises a first and a second working for performing a pump mode operation, in which working fluid of low pressure is sucked into and compressed by the working chambers. The fluid machine further comprises valve mechanism for selectively forming a motor mode passage in combination with a fluid passage change-over device, so that super heated working fluid of high pressure is introduced into at least one of the working chambers to perform a motor mode operation, in which the high pressure working fluid is expanded in the working chamber to obtain mechanical energy. The fluid machine according to the invention, therefore, performs the pump mode operation at one of the working chambers and at the same time the motor mode operation at the other working chamber.
