A mechanically actuated pumping mechanism, driven by a flexible cable connected to the engine, transfers fuel from the tank to the engine. This type of system is often found in applications where electrical power is limited or unreliable, or where an explosion-proof environment is required, such as in aircraft or certain industrial settings. One example is its usage in early aircraft engines.
Such systems offer inherent safety advantages in hazardous environments due to the absence of electrical components. Their mechanical simplicity also contributes to robustness and ease of maintenance. Historically, these pumps played a significant role in the development of aviation technology, enabling reliable fuel delivery in early aircraft. This reliable operation under harsh conditions makes them suitable for specific applications even today.
