FIELD: machine building.
SUBSTANCE: adjustment disc unit for devices of liquid medium flow adjustment comprises the first disc and the second disc. An extended cavity is formed in the surface of the first disc and the second disc. The second disc is levelled with the first disc to ensure communication by the fluid medium between the cavity of the first disc and the cavity of the second disc, at the same time the cavity of the first disc is displaced or arranged stepwise relative to the cavity of the second disc. The cavity of the first disc and the cavity of the second disc form together at least a channel for the fluid medium, having a cross section, which is characterised by increased and reduced area of cross section to form a mechanism of channel expansion/narrowing for the liquid medium.
EFFECT: reduced noise.
