F15B 9/08

controlled by valves affecting the fluid feed or the fluid outlet of the servomotor (F15B9/06 takes precedence)

Introduced: September 1968

Title

Titles differ between systems:

IPC: controlled by valves affecting the fluid feed or the fluid outlet of the servomotor

CPC: controlled by valves affecting the fluid feed or the fluid outlet of the servomotor (F15B9/06 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Servomotors with follow-up action, i.e. in which the position of the actuated member conforms with that of the controlling member > with servomotors of the reciprocatable or oscillatable type > controlled by valves affecting the fluid feed or the fluid outlet of the servomotor

CPC:

Servomotors with follow-up action, i.e. in which the position of the actuated member conforms with that of the controlling member > with servomotors of the reciprocatable or oscillatable type > controlled by valves affecting the fluid feed or the fluid outlet of the servomotor (F15B9/06 takes precedence)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
