Torus

 

a geometric solid formed by the rotation of a circle about a line lying in the plane of the circle but not intersecting the circle (see Figure 1). A torus is shaped approximately like a doughnut or a life ring. If the radius of the rotating circle is r and

Figure 1

the distance from the center of the circle to the axis of rotation is a, then the area of the surface of the torus is 4π2ar and the volume of the torus is 2π2ar2. The term “torus” is also applied to the surface bounding such a solid.

Differences in these two designs of the inside pipe drives include: a torus has closed cavity, while a sleeve has an open one; in the torus, three different modes of air pressure are used (before, inside and behind it) while in the sleeve, two modes of pressure are applied (inside and behind it); the torus operates due to difference in air pressure before and behind it, while the sleeve operates due to difference in pressure inside and behind it and can serve both as a device and as a technological material for the restoration of the pipeline while the torus can serve only as a device as it has rather small dimensions (usually not more than 3 diameters of a pipe) and all of them are alike.
