Abstract
A mixing device exhibiting a mixing chamber, feed and recirculation lines for components and for the component mixture. A control piston reciprocates inside the mixing chamber between a recirculation position where the feed and recirculation lines are in fluid communication and a mixing position where the components impinge and mix in the mixing chamber. At least one component has a straight line recirculation path from its feed to return line through a radial slot in the control piston. A bypass line branches off from at least one feed line and opens into the mixing chamber at a mixing input duct in the same radial plane as a mixing input duct for a second component.
