Title:
Power generator
Document Type and Number:
Japanese Patent JP6321569
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power generation device capable of reducing mechanical loss of a sliding portion and loss by wetting of an adjacent expansion space, and improving cycle efficiency, in the power generation device using a displacement power recovery machine.SOLUTION: In a power generation device 1 using a heat cycle, a gas-liquid separator 20 is disposed at a downstream side of an evaporator 2, a gas phase part of the gas-liquid separator 20 is connected to a gas supply passage 11 at an upstream side of a scroll expander 3, a liquid phase part is connected to a bypass passage 13 bypassing to a gas discharge passage 12 at a downstream side of the scroll expander 3, an expansion valve 6 is disposed in the bypass passage 13, and a branch passage 13a for allowing a part of liquid phase working fluid flowing in the bypass passage 13 to flow to the gas supply passage 11 at the upstream side of the scroll expander 3, is disposed between the bypass passage 13 at the upstream side with respect to the expansion valve 6 and the gas discharge passage 11 at the upstream side of the scroll expander 3.SELECTED DRAWING: Figure 1
