Abstract
Abstract The bearing block of a hydrostatic bearing carrying a cylindrical shaft member is, beside the main, centrally located hydrostatic pocket provided with at least two auxiliary pockets located opposite to each other, outside the main pocket. Each of these auxiliary pockets is by way a passage provided with throttling means connected to the source of fluid supply, and an adjustment of the pressure within the auxiliary pockets is automatically obtained if the bearing is subjected to an obliquely directed load.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A hydrostatic bearing designed to cooperate with a cylindrical surface of a shaft member and including at least one bearing block provided with a centrally located pocket connected to a source of pressure fluid supply in which the, or each block, is carried by a base support in such a manner that its position in relation thereto may be changed in at least one plane as a result of a possible deflection of the shaft member, and in which each block, beside the central pocket is provided with at least two auxiliary pockets located opposite to each other, outside the central pocket, each of said auxiliary pockets by way of a passage including throttling means being connected to the central pocket.
Claim 2
Dependent Claim
121 words
A hydrostatic bearing designed to cooperate with a cylindrical surface of a shaft member and including at least one bearing block provided with a centrally located pocket connected to a source of pressure fluid supply in which the, or each block, is carried by a base support in such a manner that its position in relation thereto may be changed in at least one plane as a result of a possible deflection of the shaft member, and in which each block, beside the central pocket is provided with at least two auxiliary pockets located opposite to each other, outside the central pocket, each of said auxiliary pockets by way of a passage including throttling means being connected to the central pocket.
Claim 3
Dependent Claim
121 words
A hydrostatic bearing designed to cooperate with a cylindrical surface of a shaft member and including at least one bearing block provided with a centrally located pocket connected to a source of pressure fluid supply in which the, or each block, is carried by a base support in such a manner that its position in relation thereto may be changed in at least one plane as a result of a possible deflection of the shaft member, and in which each block, beside the central pocket is provided with at least two auxiliary pockets located opposite to each other, outside the central pocket, each of said auxiliary pockets by way of a passage including throttling means being connected to the central pocket.
Claim 4
Dependent Claim
121 words
A hydrostatic bearing designed to cooperate with a cylindrical surface of a shaft member and including at least one bearing block provided with a centrally located pocket connected to a source of pressure fluid supply in which the, or each block, is carried by a base support in such a manner that its position in relation thereto may be changed in at least one plane as a result of a possible deflection of the shaft member, and in which each block, beside the central pocket is provided with at least two auxiliary pockets located opposite to each other, outside the central pocket, each of said auxiliary pockets by way of a passage including throttling means being connected to the central pocket.
Claim 5
Dependent Claim
43 words
The hydrostatic bearing according to claim 1, in which a development of the bearing surface is of basically square form and the central pOcket is circular, one auxiliary pocket being located at each corner portion of the square surface outside the central pocket.
