Abstract
A dispenser comprising at least two parallel, hollow cylinders for supplying different mutually reactive components to a mixing device located downstream of the cylinders. The dispenser comprises a respective first piston moveable in each of the cylinders and displaceable by a piston rod connected to the respective piston. A component for actuating the pistons rods to perform a forward stroke of the pistons in their respective cylinders for dispensing an amount of the reactive components to the mixing device comprises at least one rotatable member biased in a rotational direction by a torsion spring, and at least one flexible string attached to the rotatable member and to an element connected to the piston rods. A manually operable brake member is arranged to normally act on the rotatable member to hold it still, but, when deactivated, adapted to release the rotatable member thereby causing the pistons to dispense the reactive components to the mixing device.
