摘要： Dynamic mixers and methods have a chamber part with a discharge opening, a mixing chamber, a closing part, first and second inlet openings, and a centrical opening. The chamber and closing parts mount against each other in a rotationally symmetric manner and the closing part has substantially parallel planes, wherein a first plane averts a rotor, a second plane faces the rotor, a first inlet opening and a passage opening form a linear duct, and the substantially parallel planes form a feeding duct. Dimensions of the feeding duct are variable depending on a relative rotationally symmetric position of the chamber and closing parts, wherein the dimensions include a length, a width and/or height, and a partial circle is formable by the feeding duct and may enclose an angle of 20-170 degrees depending on the relative rotationally symmetric position of the chamber and closing parts.

摘要： Disclosed is a two-component mixing capsule for intake and for mixing of two compositions with a capsule housing having a discharge spout at its front end, wherein the mixing capsule comprises a first mixing chamber and a second mixing chamber, wherein the two mixing chambers may be separated from each other for storage or for transport, by the first mixing chamber being rotatable into a first position in which the first mixing chamber is separated from mixing chamber, by a rotatably mounted handhold element, the rotational axis of which is approximately perpendicularly arranged to the longitudinal axis of the mixing capsule. The two mixing chambers form a common mixing chamber by rotating the first mixing chamber into a second position in which the central axes of the first and second mixing chamber are substantially coaxially arranged, wherein the composition may be discharged after mixing by attaching a squeezing piston.
