Abstract
An aerosol generating system includes a heater assembly and a manually operated pump. The pump includes a hollow member with an inlet portion and an outlet portion. The inlet portion of the hollow member is configured connectable with a liquid storage portion. The outlet portion of the hollow member is in fluid communication with a dispensing assembly. The pump is configured to dispense a liquid material onto the heater assembly. The pump is configured to pump the liquid material from the liquid storage portion via the dispensing assembly and onto the heater assembly.

An aerosol generating system comprising:
- a heater assembly, and
- a manually operated pump including,
- a hollow member including,
- an inlet portion, the inlet portion being connectable to a liquid storage portion, the liquid storage portion configured to store a liquid material, and
- an outlet portion, the outlet portion being in fluid communication with a dispensing assembly, the dispensing assembly configured to dispense the liquid material onto the heater assembly, the inlet portion and the outlet portion each including a one way valve, the one-way valve at the inlet portion configured to allow the liquid material to flow from the liquid storage portion into the hollow member only, and the one-way valve at the outlet portion configured to allow the liquid material to flow from the hollow member to the dispensing assembly only, and
- a volume modifier including a moveable element, the volume modifier being configured to change an internal volume of the hollow member.
