摘要： A scroll-type compressor includes: a movable scroll including a low-stage movable tooth portion having a spiral shape and protruding from a first side of a movable substrate portion in an axial direction, and a high-stage movable tooth portion having a spiral shape and protruding from a second side of the movable substrate portion in the axial direction; and a shaft arranged to extend through the movable substrate portion and causing the movable scroll to undergo revolution motion. A low-stage compression mechanism and a high-stage movable compression mechanism are provided on opposite sides of the movable substrate portion in the axial direction. The numbers of curling of the low-stage movable tooth portion and the high-stage movable tooth portion are set to be one.

摘要： An energy conversion device includes a first acoustic wave generator, a second acoustic wave generator, and an output unit which are provided in a pipe member. The first acoustic wave generator has a thermal energy generator configured to generate thermal energy from electric energy, and converts the thermal energy generated by the thermal energy generator into acoustic energy to generate acoustic wave in working gas by a self-excited thermo acoustic vibration. The second acoustic wave generator converts thermal energy supplied from a heat supply source into acoustic energy and generates acoustic wave in working gas by a self-excited thermo acoustic vibration. The output unit converts the acoustic energy of the acoustic waves from the first acoustic wave generator and the second acoustic wave generator into cold energy to output.

摘要： A primary groove, into which a primary vane is slidably fitted, and a primary rotor-side suction passage, which conducts refrigerant of a shaft-side suction passage of a shaft to a primary compression chamber, are formed at a primary rotor. The primary groove is shaped into a form that extends from an inner peripheral side toward an outer peripheral side and extends toward a rear side with respect to a rotational direction, and the primary rotor-side suction passage is shaped into a form that extends from the inner peripheral side toward the outer peripheral side and extends and tilts toward a front side with respect to the rotational direction. A fluid outlet of the primary rotor-side suction passage opens at a location that is immediately after the primary groove on the rear side of the primary groove with respect to the rotational direction.
