摘要： The present application discloses a compressor including a crank shaft, a first reciprocation converter, a first cylinder body, a first pressurizing portion, a second reciprocation converter, which is connected to the crank shaft with a phase different by 180 degrees from the first reciprocation converter, a second cylinder body, a second pressurizing portion, and a connecting portion configured to interconnect the compression chambers. The compression chambers are arranged so that a timing at which the gas is discharged from a specific compression chamber among the compression chambers becomes the same as a timing at which the discharged gas is suctioned into another compression chamber at a higher side by one stage than the specific compression chamber.

摘要： A thermal energy recovery device includes: a circulating flow path connected to a heater, an expander, a condenser and a circulating pump for circulating a working medium; a bypass valve in a bypass path connecting the upstream side region and the downstream side region of the expander in the circulating flow path; a power recovery machine connected to the expander; a circulating pump sending the working medium condensed in the condenser to the heater; a cooling medium pump sending a cooling medium to the condenser; an upstream side sensor detecting the pressure/temperature of the working medium on the expander upstream side in the circulating flow path; and a controller controlling the bypass valve and the cooling medium pump. The controller opens the bypass valve after stopping the circulating pump, and drives the cooling medium pump if the pressure/temperature of the working medium on the expander upstream side exceeds a threshold.
