F01D 11/14 Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing (rotors with blades adjustable in operation F01D7/00)
Introduced: January 1995
Title
Titles differ between systems:
IPC: Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing
CPC: Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing (rotors with blades adjustable in operation F01D7/00)
Full Title
Full titles differ between systems:
Preventing or minimising internal leakage of working fluid, e.g. between stages > for sealing space between rotor blade tips and stator > Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing
Preventing or minimising internal leakage of working-fluid, e.g. between stages (sealings in general F16J ) > for sealing space between rotor blade tips and stator (specially-shaped blade tips therefor F01D5/20) > Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing (rotors with blades adjustable in operation F01D7/00)
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1995.
