Which of the following is an example of a three-position actuator?
A) Recirculation door
B) Blend door
C) None of these options
D) Bi-level air door
Answer (2)
A three-position actuator allows for three distinct airflow settings, usually found in automotive systems. The Blend Door is an example as it mixes hot and cold air, providing three operational states. Other options like the recirculation and bi-level doors, while functional, typically operate differently. ;
The correct example of a three-position actuator from the options provided is the Blend Door, as it can control air temperature in three distinct modes: full hot, full cold, and a mix of both. The other options mainly operate in two positions. Therefore, the answer is B) Blend Door.
