Pumpung

Pumpung is a fictional or hypothetical concept used to describe a continuous, self-regulating pumping cycle that converts mechanical energy into controlled fluid motion across a closed system. In speculative literature and theoretical discussions, Pumpung is described as a cyclical mechanism with a variable displacement chamber that alternately fills and expels fluid in response to a feedback signal.

Although the term does not denote a standard device in engineering practice, it is often treated as an abstraction for studying energy transfer, timing, and maintenance of pressure in compact systems.

In typical descriptions, Pumpung employs a compliant chamber, a drive element, and a valve arrangement that synchronizes intake and discharge. The process alternates between suction and discharge phases, with timing adjusted to minimize energy losses and pulsation.

Within fiction, Pumpung is used to explain propulsion in micro-vehicles, fluidic logic, or power storage in environments where conventional pumps are impractical. In analytical contexts, it serves as a model for examining pump efficiency, control strategies, and the impact of non-idealities, such as leakage and elastic deformation.

Variations emphasize different drive methods, such as piston-based, membrane-based, or electrohydraulic implementations. The concept remains speculative and not implemented in standard engineering practice.
