Classification: CPC F  B | IPC B  F

Claim 31:
32. An actuator for the pump according to claim 8, the actuator comprising a piezoelectric disc including a surface which comprises:
a first electrode region for electrical connection with a first conductive region of the conductive layer of the resilient isolator; and
a second electrode region for electrical connection with a second conductive region of the conductive layer of the resilient isolator,
wherein:
the first and second electrode regions are distinct from each other and the first and second conductive regions are distinct from each other, such as to provide electrical continuity between the first electrode and the first conductive region and between the second electrode and the second conductive region while providing electrical isolation between the first electrode and the second conductive region and between the second electrode and the first conductive region; and
the piezoelectric disc comprises an alignment feature for rotational alignment of the piezoelectric disc to ensure the electrical connection between the first electrode region and the first conductive region and between the second electrode region and the second conductive region.
