A compressor includes a tilting pad bearing supporting a rotating shaft in a casing. The tilting pad bearing includes a bearing pad being in sliding contact with an outer circumferential surface of the rotating shaft and a pivot supporting the bearing pad in a swingable manner. The casing includes a groove portion having an annular shape recessed in the axial direction and extending in the circumferential direction, and a connection portion configured to connect an inner circumferential region of an inner side in the radial direction with respect to the groove portion to an outer circumferential region of the outer side in the radial direction with respect to the groove portion. The connection portion overlaps with the pivot as viewed from the axial direction.

A vacuum device, in particular to a vacuum pump, includes a reservoir for an operating medium; an outlet connector arranged at or in the reservoir; and a selection device that selectively closes or opens the outlet connector or an outlet line, which is connected via the outlet connector to the reservoir, in dependence on whether the operating medium or water is present at the outlet connector.

An axial flow fan with high-temperature resistance for a ship desulfurization system includes a fan casing, axial flow fan blades, a high-temperature resistant bearing, and a cold water pipe. The axial flow fan blades are coaxially configured at an inner front end of the fan casing, and a rotating shaft is inserted in a middle of the axial flow fan blade. A middle part of the rotating shaft is sleeved with two high-temperature resistant bearings, and outsides of the two high-temperature resistant bearings are fixedly provided with a cruciform axis support. A rear end of the rotating shaft is sleeved with a worm gear, and an upper end of the worm gear is provided with a worm. The worm gear meshes with the worm. The worm gear and the worm are configured inside a lubricating oil casing, and the lubricating oil casing is covered with the insulating layer.

A turbomachine arrangement includes a housing, a turbo-expander formed with an expander rotor, a turbo-compressor formed with a first compressor rotor, and a shaft that is rotatably mounted on the housing. The shaft connects the expander rotor to the compressor rotor. The first turbo-compressor can be driven exclusively by the turbo-expander. A second turbo-compressor having a second compressor rotor is disposed on the housing such that the second compressor rotor is connected to the first turbo-compressor in parallel or in series. The second compressor rotor is driven via a transmission accommodated in the housing and via a drive shaft connecting the transmission to the second compressor rotor.

An assembly is provided that includes a shaft, a bearing, a stator seal element, a rotor seal element and a shield. The shaft extends along an axis. The bearing supports the shaft and receives lubrication fluid. The stator seal element circumscribes the shaft. The rotor seal element is mounted on the shaft axially between the bearing and the stator seal element. The rotor seal element forms a seal with the stator seal element. The shield substantially prevents the lubrication fluid from traveling axially away from the bearing onto the rotor seal element.

There is provided a turbocharger bearing housing having no necessity to use a core and capable of achieving cost reduction. A bearing housing of a turbocharger contains a shaft connecting a turbine and a compressor and turnably supports the shaft. The bearing housing of the turbocharger is divided into a turbine-side housing disposed at a turbine side and a compressor-side housing disposed at a compressor side. The turbine-side housing and the compressor-side housing is subjected to machining to thereby form a cooling water passage for supplying cooling water and a lubricating oil passage for supplying lubricating oil.
