Fluid delivery apparatus

A fluid delivery device comprising:

• a first driven element;
• a second driven element;
• and
• a drive shaft,
• the drive shaft being configured to be rotatably driven about a rotational axis,
• the first driven element being configured to be driven by the drive shaft when the drive shaft rotates in a first rotational direction and not driven by the drive shaft when the drive shaft rotates in a second rotational direction opposite to the first rotational direction,
• the second driven element configured to be driven by the drive shaft when the drive shaft rotates in the second rotational direction and not driven by the drive shaft when the drive shaft rotates in the first rotational direction,
• wherein the first driven element and the second driven element each comprise one of:
• a pump for pumping a fluid through the fluid delivery device, and
• a fluid path selector for selectively directing fluid between a selector port and one or more of a plurality of communication ports of the fluid path selector,
• wherein the second driven element comprises the fluid path selector.
