Definitions

  • a vacuum lifting device preferably for flat objects, wherein an outer cylinder, adapted to be placed on an object to be lifted, has in its interior a piston and thereabove an inner cylinder of a diameter leaving an annular chamber between both cylinders into which a U-shaped flexible sheet gasket extends from above.
  • a cover provided with a non-return valve and an air discharge valve closes the annular chamber on top.
  • the piston has a geared down piston rod in the lower end of which a reversing valve including an operating cylinder is provided which automatically opens and closes.
  • a vacuum lifting device preferably for flat objects, which comprises an outer cylinder, a holding ring and a sealing ring surrounding the lower circumference of said outer cylinder, an inner cylinder of a length shorter than that of the outer cylinder and arranged in the upper part of the latter so as to leave an annular chamber between itself and the upper wall portion of the outer cylinder, an annular cover for sealing said annular chamber on top, a piston arranged in the lower part of the outer cylinder and open on top and having a cylindrical wall adapted to be pushed into the annular chamber from below, and a movable sheet gasket secured to the upper end of the cylindrical wall of the piston to seal the annular chamber from below.
  • a vacuum lifting device wherein a non-return valve and an air discharge valve with a whistle are secured in boreholes passing through the annular cover.
