Abstract
A hydrostatic bearing device for two machine areas moving relative to each other and having faces parallel to each other with a fluid space delimited by parts of the two different machine areas and forming a gap. The fluid is under pressure in the fluid space. The gap between the two machine areas is blocked by means of a seal having a tapered end against one machine area and wherein the pressure reservoir maintains the fluid under pressure in the fluid space.
Claims7
A hydrostatic bearing device for first and second machine areas moveable relative to each other and having faces parallel to each other and having a fluid chamber defined by parts of the two different machine areas which form a gap, wherein fluid in the fluid chamber and the gap between the two machine areas is blocked by means of at least one seal, the bearing device comprising:
- at least one seal disposed in the first machine area and having a tapered contact area in contact the second machine area;
- and
- a fluid pressure reservoir in fluid communication with said gap, said fluid pressure reservoir having a pre-pressurized piston adapted to slide in a cylinder chamber, wherein said pre-pressurized piston biases against said fluid in said gap to generate and maintain the pressure in the gap.
