Abstract

The invention relates to hydrostatic bearings and seeks to provide a bearing design which affords a reduced consumption of pressure medium without increased risk of bearing breakdown as a result of inlet path blockage. According to the invention an hydrostatic bearing comprises a bearing portion (1) provided with bearing pockets (6), and a mounted portion (2) with a bearing surface (3). Pressure medium is supplied through an inlet duct (7), which extends towards the bearing surface (3) of the mounted portion (2). The end faces (10) of the inlet duct (7) and the corresponding surface (3<1>) of the mounted portion (2) form an annular throttle gap (11). A choke valve (12) may be mounted in series with the throttle gap (11) in the inlet duct (7). Because of the throttle gap (11), the effective cross section of the inlet duct (7) or choke valve (12) if used, can be made larger, thus reducing the risk of blockage of the inlet path. The annular throttle gap (11) is self-cleaning, since it consists of two parts (1) and (2) moving relative to each other.
