Abstract
A tight control device (1) for the transmission of a rotary motion from a primary shaft (3) to a secondary shaft (5), allowing the volume (P) housing the primary shaft (3) to be separated in a tightly manner from the volume (S) housing the secondary shaft (5), said device comprising a couple of sloped parallel rotating plates (7, 11), each one being fixed to a corresponding one of said shafts (3, 5), interconnected by means of oscillating parallel rods (9), articulated to corresponding C-shaped cages (13, 21) arranged around said plates (7, 11), in order to allow said plates (7, 11) to rotate therein.
Claims26
A tight control device comprising:
- a rotating primary shaft;
- a rotating secondary shaft being coaxial to said primary shaft;
- a first circular plate slopingly fixed to said primary shaft;
- a second circular plate fixed to said secondary shaft and parallel to said first plate;
- a first plurality of cages circumferentially arranged around said first plate and relative to which said first plate can rotate and a second plurality of cages circumferentially around said second plate and relative to which said second plate can rotate, each of said first cages being interconnected to a corresponding one of said second cages by means of an oscillating rod which is parallel to said shafts, hinged to said cages;
- a partition between said sloping plates provided with holes through which said oscillating rods pass;
- a sealing sleeve arranged around each of said oscillating rods in correspondence with said holes to prevent gas from flowing through said holes during the oscillating motion of said oscillating rods imparted by the rotation of said first plate caused by the rotation of said primary shaft, said oscillating motion being transmitted to said second cages to cause the rotation of said second plate and, consequently, of said secondary shaft.
A valve for fluids characterised in that it comprises a tight control device including:
- a rotating primary shaft;
- a rotating secondary shaft being coaxial to said primary shaft;
- a first circular plate slopingly fixed to said primary;
- a second circular plate fixed to said secondary shaft and parallel to said first plate;
- a first plurality of cages circumferentially arranged around said first plate and relative to which said first plate can rotate and a second plurality of cages circumferentially around said second plate and relative to which said second plate can rotate, each of said first cages being interconnected to a corresponding one of said second cages by means of an oscillating rod which is parallel to said shafts, hinged to said cages;
- a partition between said sloping plates provided with holes through which said oscillating rods pass;
- a sealing sleeve arranged around each of said oscillating rods in correspondence with said holes to prevent gas from flowing through said holes during the oscillating motion of said oscillating rods imparted by the rotation of said first plate caused by the rotation of said primary shaft, said oscillating motion being transmitted to said second cages to cause the rotation of said second plate and, consequently, of said secondary shaft.
