The additive dispensing device further includes a thermal expanding member disposed in the dispensing chamber. The thermal expanding member is configured to expand and contract between expanded and contracted positions, respectively, in response to temperature. The thermal expanding member decreases a pressure in the dispensing chamber as the thermal expanding member moves toward the contracted position, such that additive is drawn from the reservoir into the dispensing chamber through the first one-way valve. The thermal expanding member increases the pressure in the dispensing chamber as the thermal expanding member moves toward the expanded position, such that additive previously drawn from the reservoir chamber into the dispensing chamber is dispensed through the second one-way valve. | 08-20-2009 |
