    摘要： A turbomachine of this disclosure includes a rotation shaft, a first impeller, a first bearing, and a second bearing. The first impeller is fixed to the rotation shaft and includes a low-pressure-side surface. The first bearing is adjacent to the low-pressure-side surface of the first impeller and supports the rotation shaft. The second bearing is disposed on an opposite side of the first impeller from the first bearing and supports the rotation shaft. The rotation shaft includes a first tapered portion gradually increasing in diameter toward the first impeller. The first bearing includes a first support surface supporting the first tapered portion.

    摘要： A turbomachine of the present disclosure includes a rotating shaft, an impeller, a bearing, and a casing. The casing is arranged around the impeller in a circumferential direction of the rotating shaft. A volute is defined in the casing as a passage of a working fluid that is compressed or expanded by rotation of the impeller. The casing includes one or more ribs. The one or more ribs are arranged only in a diagonal area, or the one or more ribs are a plurality of ribs and a degree of reinforcement of the diagonal area by the plurality of ribs is larger than a degree of reinforcement of a tongue portion area by the plurality of ribs.

    摘要： A turbo machine according to the present disclosure includes a rotating shaft, an impeller, a first bearing, and a first supply passage. The rotating shaft includes a first taper portion and a first cylindrical portion. The first bearing includes a first taper support surface and a first cylindrical portion support surface, the first taper support surface including a first taper hole forming surface and rotatably supporting the first taper portion, the first cylindrical portion support surface rotatably supporting the first cylindrical portion. The first supply passage is open to a space formed between the first cylindrical portion and first cylindrical portion support surface. An inclination angle of the first taper hole forming surface with respect to the axial direction of the first bearing is greater than an inclination angle of an outer surface of the first taper portion with respect to the axial direction of the rotating shaft.

    摘要： A rotary compressor (100) includes a closed casing (1), a cylinder (15), a piston (28), a lower bearing member (7), a vane (33), a suction port (20), a discharge port (41), and a partition member (10). The partition member (10) is attached to the lower bearing member (7) so as to form a refrigerant discharge space (52) serving as a flow path of a refrigerant discharged from a discharge chamber (26b) through the discharge port (41). The lower bearing member (7) is provided with a first recess (7t) on the same side as the suction port (20) with respect to a reference plane, the reference plane being a plane including a central axis of the cylinder (15) and a center of the vane (33) when the vane (33) protrudes maximally toward the central axis of the cylinder (15). A portion of oil stored in an oil reservoir (22) flows into the first recess (7t), and thereby an oil retaining portion (53) is formed.
