Umbhobho oncediswa ngumoya luhlobo lombhobho we-venturi. Umgaqo-nkqubo wayo osebenzayo kukunyusa isantya sendawo yokutshiza ngohlobo lwangaphakathi lwemilomo. Isantya sokuqukuqela okuphezulu siya kwenza indawo yoxinzelelo olubi, kwaye umoya ojikelezileyo uya kutsalwa ngumda woxinzelelo olubi, ngokwenza njalo uthathe inxaxheba kukutshiza kombhobho.

Oku kuya kuzisa izibonelelo. Umbhobho womoya uya kwandisa ukuhamba komoya kunye namandla okuvuthuza ngenxa yokuba umoya ojikelezileyo uyangeniswa ngaphakathi. Umbhobho wolwelo uya kuvelisa ifuthe elomeleleyo kuba umoya utsaliwe. Umbhobho wokuxuba uya kufakwa ngaphakathi kuba ulwelo olungqongileyo lutsaliwe. Velisa Umsebenzi wokuvuselela nokudibanisa.
