Introduced: September 1968

Title

Titles differ between systems:

IPC: characterised by the input flow of inducing fluid medium being radial or tangential to output flow

CPC: characterised by the input flow of inducing fluid medium being radial or tangential to output flow (cyclones B04C)

Full Title

Full titles differ between systems:

IPC:

Jet pumps, i.e. devices in which fluid flow is induced by pressure drop caused by velocity of another fluid flow > characterised by the input flow of inducing fluid medium being radial or tangential to output flow

CPC:

Jet pumps, i.e. devices in which flow is induced by pressure drop caused by velocity of another fluid flow (diffusion pumps F04F9/00; combination of jet pumps with pumps of other than jet type F04B; use of jet pumps for priming or boosting non-positive-displacement pumps F04D) > characterised by the input flow of inducing fluid medium being radial or tangential to output flow (cyclones B04C)
