Actuation and valve mechanism

An apparatus comprising:

• a fluid control barrier member;
• and
• a cable drive device, for moving the fluid control barrier, the cable drive device comprising:
• a linear drive member having opposite ends;
• a single cable drum;
• a support bracket comprising:
• first and second opposing face plates, which guide the linear drive member through the support bracket, between the first and second face plates and adjacent the cable drum;
• and
• at least one element extending from the first face plate to the second face plate such that the linear drive member is positioned between the single cable drum and the at least one element to retain the linear drive member adjacent the single cable drum;
• and
• a cable;
• at least one of the ends being attached or attachable to the fluid control barrier;
• the single cable drum being attached to the support bracket;
• the single cable drum having an axle with a portion extending between and supported by the first and second face plates to allow rotation of the single cable drum;
• the cable being affixed at each of the ends and tautly wrapped around the single cable drum;
• the single cable drum being located between the ends to move the linear drive member longitudinally through the support bracket when the axle is rotated.

A cable drive device comprising:

• a linear drive member having opposite ends;
• a support bracket adapted to be affixed to a surface and having first and second opposing face plates which guide the linear drive member through the support bracket between the first and second face plates and adjacent the cable drum;
• and
• a single cable drum attached to the support bracket, said single cable drum having an axle with a portion extending between and supported by the first and second face plates to allow rotation of said single cable drum, said single cable drum having a cable affixed at at least one of the ends of said linear drive member and tautly wrapped around said single cable drum, said single cable drum being located between said ends of said linear drive member to allow said linear drive member to be guided longitudinally through said support bracket to move said linear drive member longitudinally when said axle is rotated,
• wherein the support bracket comprises at least one element extending from the first face plate to the second face plate such that the linear drive member is positioned between the single cable drum and the at least one element to retain the linear drive member adjacent the single cable drum.
