Molecular pump
First Claim
1. Molecular pump, which makes it possible to evacuate a gas from a chamber and to thus create a high vacuum, that comprises a substantially sealed box (1) having on one of its sides an intake orifice (2) to be connected to said chamber and, on the opposite side, an outlet orifice (3), to be preferably connected to a discharge pump, whereby elements (4) are mounted between those two orifices (2) and (3) at some distance from one another in substantially fixed sites inside said box (1) for the gas to pass through, said elements (4) being of such a nature as to impart to said gas molecules, coming from said chamber and coming into contact with said elements (4), a speed whereof the resultant is oriented towards the outlet orifice (3).

Abstract
The invention concerns a molecular pump for evacuating a gas from a chamber, comprising a substantially sealed box (1) having on one of its sides an intake orifice (2) to be connected to said chamber and, on the opposite side, an outlet orifice (3), to be preferably connected to a discharge pump, whereby elements (4) are mounted between those two orifices (2) and (3) at some distance from one another in substantially fixed sites inside said box (1) for the gas to pass through, said elements (4) being of such a nature as to impart to said gas molecules, coming from said chamber and coming into contact with said elements (4), a speed whereof the resultant is oriented towards the outlet orifice (3).

- 17. Molecular pump, which makes it possible to evacuate a gas from a chamber and to thus create a high vacuum, that comprises a substantially sealed box (1) having on one of its sides an intake orifice (2) to be connected to said chamber and, on the opposite side, an outlet orifice (3), elements (4) being mounted between those two orifices (2) and (3) at some distance from one another on fixed supports (5) inside said box (1) for the gas to pass through, characterized in that said elements (4) are mounted on the fixed supports (5) on the side of the latter directed towards the outlet orifice (3), in such a way as to determine with these supports a succession of dipoles, whose active sides, formed by these elements, are also oriented towards the outlet orifice and to allow implying an acceleration of the gas molecules, coming from said chamber and coming into contact with these elements, towards the outlet orifice.
