Claim 15:
16. An aircraft comprising:
a fuselage (102);
a first hydraulic braking system (114), connected to the fuselage (102); and
a shuttle valve (200, 600), operably connected to the first hydraulic braking system (114), the shuttle valve (200, 600) comprising:
a first inlet (604);
a manifold chamber (608) in fluidic communication with the first inlet (604);
a second inlet (606) in fluidic communication with the manifold chamber (608);
an outlet (610) in fluidic communication with the manifold chamber (608); and
a spool-sleeve assembly (300), positioned inside the manifold chamber (608) and comprising:
a sleeve (302), comprising a first end (304, 704), a second end (306, 706), a first inner radius (310), a second inner radius (338), and a third inner radius (342);
a spool (348, 702), slidably located inside the sleeve (302) and comprising a third end (350, 748) and a fourth end (352, 750);
a first flange (312), integrally formed with the sleeve (302) and outwardly extending from the first end (304, 704) of the sleeve (302);
a second flange (324), integrally formed with the sleeve (302) and outwardly extending from the second end (306, 706) of the sleeve (302);
a first press fitting (336), located on a first inner wall (308) of the sleeve (302);
a second press fitting (340), located on the first inner wall (308) of the sleeve (302);
a first hole (344), located through the sleeve (302) between the first flange (312) and the second flange (324);
a first ridge (358, 752), outwardly extending from the spool (348, 702) proximate the third end (350, 748) of the spool (348, 702); and
a second ridge (364, 754), outwardly extending from the spool (348, 702) proximate the fourth end (352, 750) of the spool (348, 702),

wherein:
the first flange (312) is segmented into a first plurality of flange segments (707) via a first slit (318), located in the first flange (312);
the second flange (324) is segmented into a second plurality of flanges (717) via a second slit (330), located in the second flange (324);
the first press fitting (336) is inwardly located on the first inner wall (308) of the sleeve (302) proximate the first end (304, 704) and the first slit (318);
the second inner radius (338) of the sleeve (302) is at the first press fitting (336);
the second inner radius (338) of the sleeve (302) is smaller than the first inner radius (310) of the sleeve (302);
the second press fitting (340) is inwardly located on the first inner wall (308) of the sleeve proximate the second end (306, 706) and the second slit (330);
the third inner radius (342) of the sleeve (302) is at the second press fitting (340);
the third inner radius (342) of the sleeve (302) is smaller than the first inner radius (310);
the third end (350, 748) is sized and dimensioned to block the first inlet (604) and the fourth end (352, 750) is sized and dimensioned to block the second inlet (606);
the first ridge (358, 752) comprises a first outer diameter (360, 1200), which is greater than the second inner radius (338) of the sleeve (302), and a first groove (362, 760), located in the first ridge (358, 752);
the second ridge (364, 754) comprises a second outer diameter (366, 1202), which is greater than the third inner radius (342) of the sleeve (302), and a second groove (368, 762), located in the second ridge (364, 754);
the first press fitting (336) is sized and dimensioned so that at least a first portion of the first press fitting (336) fits in the first groove (362, 760); and
the second press fitting (340) is sized and dimensioned so that at least a second portion of the second press fitting (340) fits in the second groove (368, 762).
