Abstract
An aerosol-generating device includes a pump. The pump includes a first pump chamber and a second pump chamber on opposing sides of a separation element. Each of the first pump chamber and the second pump chamber have an inlet valve and an outlet valve configured to establish a pumping direction. The pump also includes a first actuator and a second actuator. The first actuator is associated with the first pump chamber and the second actuator is associated with the second pump chamber. The first actuator and the second actuator are each configured to change a chamber volume of the respective pump chamber. The pump further includes a common inlet, and a common outlet. The common inlet and common outlet are in fluid communication with the first pump chamber and the second pump chamber and are configured to establish a flow direction. The pumping direction is aligned with the flow direction.
