Patent ID: 8256472

Claim:
An auxiliary device comprising a housing, wherein the housing comprises: a holder for holding a fluid-containing reservoir, said fluid-containing reservoir including a movable actuator for activating a pressure unit to dispense a quantity of fluid; an actuator driver for activating the movable actuator of the fluid-containing reservoir when the fluid-containing reservoir is connected to the holder so as to transfer the quantity of fluid to an outlet of the auxiliary device and from the outlet to the a refillable container connectable to outlet through a conduit; a powered driver configured to drive the actuator driver; and a transmission for drivingly coupling the actuator driver to the powered driver, wherein the transmission comprises a cam-shaped wheel and a lever rotatable around an axis of rotation of the lever and mounted to the housing at a distance from an axis of rotation of the cam-shaped wheel as seen in a direction perpendicular to a direction of the reciprocating motion so that vibration near the axis of rotation of the lever is reduced compared to a vibration near the cam-shaped wheel, wherein the outlet of the auxiliary device is located near the axis of rotation of the lever, and wherein the cam-shaped wheel contacts the lever and the actuator driver is releasably mounted to the lever, and the conduit is releasably connected to the lever so that the conduit moves together with the lever when the auxiliary device is in operation.
