251294000 FLEXIBLE ACTUATOR (E.G., BOWDEN WIRE; CHAIN) 1
20120313024Compact reed valve - Compact reeds maximize flexural length by efficiently utilizing available space surrounding the port. Maximum length arms are disposed at the perimeter of the housing inlet port. Stresses at the ends of the arms are mitigated by utilizing compound radius transitions.

The arms are disposed close to the reed sealing surface edge to orient the flow streamlines to be aligned with the arm width, thereby minimizing frontal drag area. The reduced frontal area reduces drag forces and related stresses on the arms, and reduces the overall flow related pressure drop across the reed.12-13-2012
