Patent ID: 11812819

Abstract:
Bladder systems for footwear include: two inflation chambers; a valve body defining: (a) a bore, (b) a first fluid passage extending to the bore, (c) a second fluid passage extending between the bore and one inflation chamber, and (d) a third fluid passage extending between the bore and another inflation chamber; and a valve in the bore. The valve includes two orifices connected by a passage and rotates in the bore between two positions. In one position, a first orifice (of the “orifices”) is in fluid communication with the first fluid passage and a second orifice is in fluid communication with the second fluid passage to allow fluid flow to one inflation chamber. In another position, the first orifice is in fluid communication with the third fluid passage and the second orifice is in fluid communication with the first fluid passage to allow fluid flow to the other inflation chamber.
