DISPOSITIVO PER DOSARE COMPONENTI DI UNA COMPOSIZIONE LIQUIDA,IN PARTICOLAR VERNICI

摘要

A device for metering paint components comprises a number of metering valves (3) disposed annularly and movably on holder (2) and connected to a line (4) for the infeed of the particular component. Displacement means for shifting each of valves (3) to the centre of the circle and back comprise a holder (5) coaxially rotatable inside annular holder (2) and bearing a movable displacement element (12), with holds and moves the metering valve (3) by means of connector (13). A control device (16) is disposed in the centre of the circle for operation of a valve positioned there. Holder (5) preferably comprises a radial arm (11) over which the displacement element (12) moves. Rotatable holder (5) also bears a cleaning element (20) movable in the vertical direction relative to the holder and which can be placed against the lower side of each of the metering valves to spray them with cleaning solvent which drains away through a funnel and hose.
