Abstract
Abstract A bearing which ensures automatic alignment of a part to be guided and comprises a stationary supporting frame, a core which is placed within the frame and provided with elements for securing the part, pistons fitted within cylinders which are formed in the frame and each open on the core. Each piston is applied against an oil chamber of small width by means of the piston face which is remote from the core. Each chamber is connected through a high pressure drop inlet to a reservoir which contains oil under pressure and is fitted with a compensation system for maintaining the pressure at a practically constant value.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
A bearing which ensures automatic alignment of a part to be guided, wherein said bearing essentially comprises a stationary supporting frame, a core which is placed within said frame, a bore in said core receiving the part to be guided, pistons located in each case in a cylinder which is pierced in said supporting frame and has its opening on said core, an oil chamber having a small width and each piston face remote from the face which is directed towards said core being applied against said oil chamber, each chamber being connected by means of a high pressure drop inlet orifice to a reservoir which contains oil under pressure and is fitted with a compensation system for maintaining the pressure at a practically constant value.
Claim 2
Dependent Claim
126 words
A bearing which ensures automatic alignment of a part to be guided, wherein said bearing essentially comprises a stationary supporting frame, a core which is placed within said frame, a bore in said core receiving the part to be guided, pistons located in each case in a cylinder which is pierced in said supporting frame and has its opening on said core, an oil chamber having a small width and each piston face remote from the face which is directed towards said core being applied against said oil chamber, each chamber being connected by means of a high pressure drop inlet orifice to a reservoir which contains oil under pressure and is fitted with a compensation system for maintaining the pressure at a practically constant value.
Claim 3
Dependent Claim
51 words
A bearing according to claim 1, wherein the core of said bearing is movable with respect to the stationary supporting frame (guiding in translational motion), said supporting frame being fitted with shoes and each shoe being applied against one of said pistons, guiding in translational motion being effected by said bearing.
Claim 4
Dependent Claim
23 words
A bearing according to claim 2, wherein said shoes are roller-type shoes, said rollers being displaceable on a track of the movable core.
Claim 5
Dependent Claim
12 words
A bearing according to claim 2, wherein said shoes are sliding shoes.
Claim 6
Dependent Claim
29 words
A bearing according to claim 1, wherein the core of said bearing is stationary with respect to the supporting frame and serves to guide a part in rotational motion.
