Jet pipe servo with flexure pivot

A jet pipe servo device, comprising:

• an electromagnet assembly including a coil and an armature;
• a seal tube receiving the armature and disposed between the coil and the armature fixed with respect to the coil;
• a flexure pivot having a first part fixed with respect to the coil and second part linked to the armature and movable therewith with respect to the first part;
• a jet pipe linked to the second part of the flexure pivot;
• and
• a jet receiver having first and second orifices, the first orifice receiving media from the jet pipe when the armature is in a first position and the second orifice receiving media from the jet pipe when the armature is in a second position;
• wherein the first and second parts of the flexure pivot are joined by struts defining passages for communicating media passing through the first and second parts to a passageway of the jet pipe.

A jet pipe servo device, comprising:

• a servo valve, including:
• an electromagnet;
• a flexure pivot having:
• first and second parts movable with respect to one another, the first part having one or more first openings therethrough;
• struts joining the first part to the second part;
• and
• passages for communicating media through the flexure pivot, the passages extending through the struts from at least one of the first openings of the first part to the second part;
• a jet pipe fixed to the second part of the flexure pivot and movable with respect to the first part of the flexure pivot;
• and
• a jet receiver having first and second orifices, the first orifice receiving media from the jet pipe when the armature is in a first position and the second orifice receiving media from the jet pipe when the armature is in a second position;
• and
• an actuator, including:
• a cylinder and a piston arrangement and wherein the media from the jet pipe passing through the first orifice actuates the piston and media from the jet pipe passing through the second orifice retracts the piston.
