In an ejector cycle having an ejector for decompressing refrigerant, a check valve is disposed in an oil return passage through which refrigerant including a lubrication oil is introduced from a refrigerant outlet side of an evaporator to a refrigerant suction side of a compressor while bypassing the ejector. When the lubrication oil amount staying in the evaporator reduces, the check valve is automatically closed, and a normal operation mode of the ejector cycle is automatically set. On the contrary, when a large amount of lubrication oil stays in the evaporator, the check valve is automatically opened, and an oil return mode is automatically set. Therefore, the lubrication oil staying in the evaporator can be controlled equal to or lower than a predetermined amount, thereby effectively returning the lubrication oil to the compressor.

A vaporizer is provided with a vaporizing chamber heated by heaters; a primary filter positioned in a bottom end portion of the vaporizing chamber and heated by the heater; a liquid material supply portion for dropping down a flow-controlled liquid material from upper portion of the vaporizing chamber toward the primary filter; a carrier gas guiding passage for guiding a carrier gas into the underside of the primary filter; and a material delivering passage for discharging a mixed gas including the carrier gas and a vaporized liquid material from the top of the vaporizing chamber. The liquid material dropped down onto the primary filter is partially vaporized, while the rest thereof is atomized by being subjected to bubbling effect provided by the carrier gas flowing from underneath.

A liquid storage device for a propellant tank in a spacecraft includes a gas-guide tube, a cover plate, a housing, blades, a supporting column, a base, a passage-window pressing plate, a passage-window mesh piece, a liquid-storage-device mesh piece, a fixing block, and a pressing plate for the liquid-storage-device mesh piece. The blades are uniformly distributed on and fixed to the support column in a radial direction to form an integral structure, and the integral structure is mounted on and fixed to a circular partition plate in the base. The liquid-storage-device mesh piece is pressed on the circular partition plate in the base by the pressing plate for the liquid-storage-device mesh piece and then is fixed. The passage-window mesh piece is pressed on the outer side of a cylinder wall of the base by the passage-window pressing plate and then is fixed.

The pin gear-cycloid gear hydraulic pump has driving shaft, pump core and valve inside the pump body. The pump core is rotated with the driving shaft, and has drawing cavity connected to conveying pipeline via valve. The pump core is one pin gear-cycloid gear mechanism comprising inner rotor, pin gear, and inner cycloid gear; the inner rotor is set eccentrically relative to the inner cycloid gear and meshed with the pin gear and the inner cycloid gear successively. The inner rotor and the inner cycloid gear and two adjacent pin gears constitute one drawing cavity. The pin gear is eccentric and has fixed rotating shaft and rotating axis distributed on one cylindrical surface with the rotating shaft of the inner cycloid gear as the axis. The hydraulic pump of the present invention has the advantages of several drawing cavities, no fluctuation in flow rate, less liquid pressure impact, less noise, less energy loss, less wear, long service life, etc.
