Abstract: A turbo device provides a flow-path arrangement in a generator device. Part of a working fluid are used to lubricate at least one of a first bearing part, a second bearing part and a bearing assembly, or the working fluid of an auxiliary flow channel is led to a generator housing for cooling the generator device. In addition, a circulatory system is also provided to include bearing loops and auxiliary loops for leading the working fluid to lubricate at least one of the first bearing part, the second bearing part and the bearing assemble part, and to cool the generator device.

Abstract: A hydrostatic bearing assembly including a bearing and two membrane throttles is provided. The bearing is adapted to be movably disposed on a slide rail and includes two sub-bearing portions that are disposed opposite to each other on two opposite sides of the slide rail. The two membrane throttles are adapted to be connected to a pump. The pump is adapted to supply a fluid through the two membrane throttles to flow between the two sub-bearing portions and the slide rail, and each of the membrane throttles includes a casing and a throttling membrane piece. At least one of the casing and the corresponding sub-bearing portion includes a chamber, an inlet and an outlet communicating with the chamber, and an outlet surface, wherein the pump is adapted to be connected to the inlet, and the slide rail is adapted to be disposed adjacent to the outlet. The throttling membrane piece is being positioned in the chamber covers on the outlet surface.

Abstract: A membrane restrictor adapted to be connected to a pump and a bearing is provided. The pump is adapted to supply fluid to a location between the bearing and the rail through the membrane. The bearing is adapted to be disposed on a rail. The membrane restrictor includes a casing and a membrane. The casing has a chamber, an inlet and an outlet communicating with each other through the chamber, and a restricting plane. The pump is adapted to be connected to the inlet; the bearing is adapted to be connected to the outlet. The membrane is disposed in the chamber. The restricting plane is an inner surface of the casing adjacent to the outlet and towards the membrane. Dimensionless stiffness of the membrane is Kr*, and 1.33?Kr*?2. Kr*=KrL0/(psAr). Here, Kr is stiffness of the membrane, L0 is a distance from the membrane to the restricting plane when no fluid is supplied by the pump (i.e., assembling clearance of the membrane), ps is pressure supplied by the pump, and Ar is an effective area of the restricting plane.
