The latter is fitted on central shaft arranged in carcass plane with its extensions attached to air intake housing. Aforesaid shaft is made from alloy that features thermo mechanical shape memory and fixed relay twisting about lengthwise axis through 90 degrees relative to initial state when alloy reached temperature threshold of operation.
EFFECT: simplified design, reduced flow disturbances in idle conditions.
