Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A device for distributing a gas in ionization chambers, for space thrusters and other uses, comprising at least one nozzle with a calibrated hole for the discharge of the said gas into the said ionization chamber, wherein the calibrated hole (1512; 1524; 1532) is formed in a component made of hard material (1510; 1522; 1530) which is inserted in the wall (11) of the distributor at the position of a passage (1514; 1524; 1534) formed in the wall.
Claim 2
Dependent Claim
24 words
The device as claimed in claim 1, wherein the said component (1510; 1522, 1530) is fixed to the wall (11) with an adjustable orientation.
Claim 3
Dependent Claim
32 words
The device as claimed in claim 2, wherein the said component (1522; 1530) and the wall have, for mutual contact, complementary surfaces of revolution, which permit variations of orientation of the component.
Claim 4
Dependent Claim
22 words
The device as claimed in claim 3, wherein the said component and the wall have, for mutual contact, portions of spherical surfaces.
Claim 5
Independent Claim
24 words
The device as claimed in at least one of claims 1-4, wherein the said component is made of ruby or other equivalent hard material.
Claim 6
Dependent Claim
38 words
The device as claimed in at least claim 1, with a plurality of nozzles with calibrated holes, wherein each nozzle has a pierced component made of hard material to provide calibrated holes of different sections and/or different orientations.
Claim 7
Independent Claim
38 words
The device as claimed in at least one of claims 1-6, wherein a pierced component (1510, 1522, 1530) is applied by puttying and/or by mechanical forcing on the outside of the wall forming the support and main duct.
Claim 8
Independent Claim
33 words
The device as claimed in at least one of claims 1-6, wherein a pierced component (2003) may be inserted through a passage (2005) and is positioned in the said passage from the inside.
