Patent ID: 8245729

Claim:
A fluid control device, comprising: a body including a first cavity ( 136 ), a first body end ( 106 ), and a second body end ( 108 ); a movable part ( 104 ) having a first end located inside the first cavity ( 136 ) where the first end is located at a first position inside the first cavity ( 136 ) when the movable part ( 104 ) is at an activated position and where the first end is positioned inside the first cavity ( 136 ) at a second position when the movable part ( 104 ) is at a non-activated position and where the first end displaces a first volume between the first position and the second position; a first passageway ( 139 ) in fluid communication with the first cavity; a pressure controlled first fluidic switch ( 113 ) located internally to the first body end and in fluid communication with the first passageway ( 139 ); a first signal port ( 120 ) formed in the body and coupled to the first fluidic switch ( 113 ) and a first exhaust passageway ( 141 ) formed in the body and coupled to the first fluidic switch ( 113 ) where the first fluidic switch is configured to fluidly couple the first passageway ( 139 ) with the first signal port ( 120 ) when the first signal port ( 120 ) is pressurized and where the first fluidic switch ( 113 ) is configured to fluidly couple the first passageway ( 139 ) with the first exhaust passageway ( 141 ) when the first signal port ( 120 ) is not pressurized thereby exhausting the first volume through the first exhaust passageway ( 141 ).
