Italian to English Tech/Engineering Mechanics / Mech Engineering Cross-cutting saw

It's from a list of machine (spare?) parts.
The little context I have:
"CILINDRO – CAPPA PRESSORE
SENSORE PNEUMATICO CAPPA PRESSORE
VALVOLA 5/2 BISTABILE – CILINDRO CAPPA PRESSORE"


As I said, very little context. The whole text is in a sort of Italo-English (probably translated to English by client), with a few tables and sentences left in Italian; I'm supposed to translate the Italian bits into Estonian, and as usual, I have to work through English-Estonian dictionaries (there are no good it-et dictionaries) and look for English terms first. Now, the surrounding English text would be of some help if I were sure I could trust the terminology there - but I'm not (it's full of words like "bifore" and sentences like "The cutting tool is made by a circular blade, the whose rotation movement is supplied directly from an electrical motor and the whose feed movement towards the piece to work is assured by a pneumatic cylinder" - not exactly trustworthy, see what I mean? I'd rather have the whole text in Italian.

In English text there is a "pressure hood" - in "the movement of the pressure hood is also assured by a pneumatic cylinder, that allows whether the lifting of the hood or the blocking of the piece into the table to assure a suitable grade of stability during the work phase" - but the sentence itself doesn't look too good and the term looks suspiciously like a simple literal translation (I do NOT envy the translator that has to work on the English part of the document, given the quality). So, I'm open to alternative versions. And, as always, just explanations are welcome as well.
