1. An apparatus comprising:

  • at least one pair of opposing surfaces formed on a support structure for movement relative to one another;

    an actuator operably engaging the support structure for driving the at least one pair of opposing surfaces relative to one another in response to an electrical activation of the actuator;

    at least one fluid flow passageway extending through at least a portion of the support structure and defining an inlet, an outlet, and a valve seat disposed within the passageway and positioned with respect to one of the at least one pair of opposing surfaces; and

    a valve surface supported with respect to the other of the at least one pair of opposing surfaces for regulating fluid flow through the at least one passageway at the valve seat in response to an electrical activation of the actuator.
