Abstract
The invention is a device (1, 100, 200, 300, 400, 500, 600, 700) for converting a rotary motion into a linear motion, comprising a first threaded element (3) that defines a first axis (7), suited to be coupled with a second threaded element (4) defining a second axis (10), said axes (7, 10) being substantially parallel to each other but not coinciding with each other. The device (1) also comprises means (12) arranged between the first threaded element (3) and the second threaded element (4), suited to transmit the rotary motion imparted to one of the elements (3, 4) to the other.

A device for converting a rotary motion into a linear motion, comprising:
- at least a first threaded element that defines a first axis, said first threaded element being coupled with at least one second threaded element defining a second axis, said axes being parallel to each other but not coinciding with each other;
- and
- means arranged between said at least one first threaded element and said at least one second threaded element suited to transmit a rotary movement imparted to one of said elements to the other by friction,
- wherein said means comprise at least one annular element housed in an annular seat obtained on an annular support mounted on said at least one second threaded element.
