Abstract: A refrigeration apparatus includes a container such as an evaporator for holding refrigerant, and a compressor for compressing refrigerant vapor. The compressed vapor is returned to the container, and stored as liquid. The liquid refrigerant is withdrawn from the container and then returned to the container via a first path through a heat exchanger for cooling a space, or a second path that does not pass through the heat exchanger. Upon returning to the container, the liquid refrigerant is at least partly evaporated due to the reduced pressure in the container caused by the operation of the compressor, and the container is cooled by the latent heat of evaporation. Thus, the container can act as a cold storage unit. The cold storage effect is increased when the refrigerant is returned to the container via the second path.

Abstract: A turbo machine of the present disclosure includes a rotation shaft, a first bearing, a casing, an impeller, a first space, a second space, a storage tank, a first outlet passage, a supply passage, a pump, a main passage, and a sub-passage. The second space is in communication with a space formed between a bearing surface of the first bearing and an outer surface of the rotation shaft. The main passage is in communication with the second space and extends in the rotation shaft from an end of the rotation shaft in an axial direction of the rotation shaft. The sub-passage is formed in the rotation shaft and allows communication between the space between the bearing surface of the first bearing and the outer surface of the rotation shaft and the main passage.

Abstract: 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.

Abstract: A turbo machine of the present disclosure includes a cylindrical bearing housing, a rotation shaft, a bearing, a bearing holder, and an end elastic body. The rotation shaft is located in the bearing housing. The bearing rotatably supports the rotation shaft at least in a radial direction of the rotation shaft. The bearing holder faces one end of the bearing and is fixed to the bearing housing. The end elastic body is disposed between the one end of the bearing and the bearing holder in the axial direction of the bearing and is in contact with the bearing and the bearing holder. The end elastic body is formed of a material having a lower modulus of elasticity than a material forming the bearing holder.
