Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
232 words
A fluid device for stabilizing the position of a movable body in relation to a fixed body, of the type comprising two opposing chambers separating said two bodies, a slide valve for supplying pressurized fluid selectively to said two opposite chambers, and a control system for said slide valve comprising an enclosure, a gas tight movable partition connected to said slide valve and separating said enclosure into a primary chamber and a secondary chamber, a primary supply line and a secondary supply line, said primary and secondary chambers being connected respectively to said primarY and secondary supply lines, said primary and secondary supply lines being connected to a pressurized gas source through two jets and open to the atmosphere through two throttles controlled by said slide valve so that the effective areas of said throttles vary together and in the same direction, said primary supply line being still open to the atmosphere by a jet measuring the proximity of the relative position of said two bodies, whilst said secondary supply line is also open to the atmosphere through a reference jet, said device being characterized by orifice means, respectively between (1) said primary line and said primary chamber and (2) said secondary line and said secondary chamber, said enclosure having a minimum volume compatible with the maximum deflections of said movable partition to limit the movement of said partition between extreme positions.
Claim 2
Dependent Claim

A fluid device for stabilizing the position of a movable body in relation to a fixed body, of the type comprising two opposing chambers separating said two bodies, a slide valve for supplying pressurized fluid selectively to said two opposite chambers, and a control system for said slide valve comprising an enclosure, a gas tight movable partition connected to said slide valve and separating said enclosure into a primary chamber and a secondary chamber, a primary supply line and a secondary supply line, said primary and secondary chambers being connected respectively to said primarY and secondary supply lines, said primary and secondary supply lines being connected to a pressurized gas source through two jets and open to the atmosphere through two throttles controlled by said slide valve so that the effective areas of said throttles vary together and in the same direction, said primary supply line being still open to the atmosphere by a jet measuring the proximity of the relative position of said two bodies, whilst said secondary supply line is also open to the atmosphere through a reference jet, said device being characterized by orifice means, respectively between (1) said primary line and said primary chamber and (2) said secondary line and said secondary chamber, said enclosure having a minimum volume compatible with the maximum deflections of said movable partition to limit the movement of said partition between extreme positions.
Claim 3
Dependent Claim
38 words
A device according to claim 1, wherein said slide valve and said two throttles controlled by said slide valve are constituted by a unit of four coaxial valves biased one against the other and against said movable partition.
Claim 4
Dependent Claim
65 words
A device according to claim 2, wherein said valves for controlling said two throttles have stems bearing respectively against the two opposite faces of said movable partition whilst the other two valves have stems bearing against said first two valves respectively under the action of the pressure of the fluid of which they control the supply towards said two opposing chambers separating said two bodies.
Claim 5
Dependent Claim
37 words
A device according to claim 1, wherein said calibrated restrictions are provided with means for regulating their effective areas and control members for actuating said regulating means, said control members being accessible from outside of the device.
