Classification Context

Section:: MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
Class:: FLUID-PRESSURE ACTUATORS; HYDRAULICS OR PNEUMATICS IN GENERAL
Subclass:: FLUID-CIRCUIT ELEMENTS PREDOMINANTLY USED FOR COMPUTING OR CONTROL PURPOSES

Description

Covers fluid-based logic and control systems employing hydraulic or pneumatic circuit elements designed to perform computational, control, or decision-making functions. This includes fluidic logic gates, fluid amplifiers, fluid oscillators, and integrated pneumatic/hydraulic control circuits that process signals or regulate system behavior without electronic components. Distinct from general fluid power transmission (F15B) and standard actuators (F15B, F15D), this class focuses on elements where fluid dynamics itself implements the control logic or signal processing function.
