Patent ID: 7102113

Claim:
A three-axis attitude control propulsion device comprising a pressure generating means and two three-way discharge changeover means connected to one end of said pressure generating means, said two three-way discharge changeover means positioned with 180 degrees between each other in a rotational symmetry around a reference of an axis of said pressure generating means, wherein one of said two three-way discharge changeover means has three discharge ports, said three discharge ports having openings having orientations including (a) an orientation at a first specific angle, (b) an orientation deviated by 90 degrees counterclockwise from said first specific angle and (c) an orientation deviated by 90 degrees clockwise from said first specific angle, the other of said two three-way discharge changeover means has three discharge ports, said three discharge ports of the other of said two three-way discharge changeover means having openings having orientations including (d) an orientation at a second specific angle that is deviated by 180 degrees from said first specific angle, (e) an orientation deviated by 90 degrees clockwise from said second specific angle and (f) an orientation deviated by 90 degrees counterclockwise from said second specific angle, and said orientation deviated by 90 degrees counterclockwise from said first specific angle and said orientation deviated by 90 degrees clockwise from said second specific angle are parallel to each other.
