G05D16/0663 - CPC Classification

Classification description:

Control of fluid pressure without auxiliary power the sensing element being a flexible membrane, yielding to pressure, e.g. diaphragm, bellows, capsule the sensing element being a membrane the membrane acting directly on the obturator using a spring-loaded membrane with a spring-loaded slideable obturator

Sub-classes:

G05D16/0666 » {characterised by the form of the obturator} 36
G05D16/0669 » {characterised by the loading mechanisms of the membrane} 18
