DIFF Subclass Not Allocatable
G05G

CONTROL DEVICES OR SYSTEMS INSOFAR AS CHARACTERISED BY MECHANICAL FEATURES ONLY ("Bowden" or like mechanisms F16C1/10; gearings or mechanisms not peculiar to this purpose F16H; speed changing or reversing mechanisms for gearings conveying rotary motion F16H59/00 - F16H63/00)

Introduced: September 1968

Description

G05G covers mechanical control devices and systems where the controlling function is achieved through purely mechanical means, without electrical or electronic components. This includes mechanical governors, mechanical regulators, mechanical feedback systems, and mechanical servo mechanisms used in engines, turbines, and industrial machinery. The classification encompasses devices such as centrifugal governors, mechanical linkages for control purposes, and mechanical threshold or limit devices. Adjacent electrical or electronic control systems are classified separately in G05B and related subclasses.
