Abstract
A dispenser provides measured doses of at least two components using a common pump. Each of the components is stored in its own separate container; each of which is connected to the common piston pump through an inlet valve. A metering device is disposed between the inlet valves and the pump chambers. The metering device is rotatable around an axis and controls the volume of each component disposed by either changing to flow rate of the component through its inlet valve or by changing the stroke length of the piston associated with its inlet valve.
Claims9
Dispenser (1) for dosing of at least two components each contained in a reservoir (6a, 6b) by means of a common pump (2) having an inlet valve (2′) for each component, a pump volume (2b) with a piston (2a) and a dispenser head (5) for discharging of the components, wherein a metering device (3) is provided for dosage of amount ratios of each component,
- characterized in that the metering device (3) is arranged within the pump volume (2b) of the pump (2) and a rotatable metering element (3a) is provided for oppositely changing the flow section and/or flow length of the components.
