A pressure compensating device for a bearing housing

The pressure-compensating device is for a bearing housing and comprises a sealed space. Pressure variations within the sealed space are compensated. It comprises a housing (5,6,7), in which a bellows of flexible material (9) is positioned. The housing has at least a first aperture (10), through whic...

Zusammenfassung:	The pressure-compensating device is for a bearing housing and comprises a sealed space. Pressure variations within the sealed space are compensated. It comprises a housing (5,6,7), in which a bellows of flexible material (9) is positioned. The housing has at least a first aperture (10), through which the interior of the bellows communicates with the side of the bearing housing where the varying pressure can be expected, and where the bellows is associated with a further aperture (8), which permits the bellows to alter its momentary shape to compensate such pressure variations.
