longitudinal axis, a first side wall and a second side wall arranged opposite the first side wall, a deflection element arranged adjacent to the first wall element, the deflection element having a deflection surface extending in a transverse direction to the first wall element at both sides of the wall element, the deflection surface having a first opening at a side facing the first side wall of the first wall element, a second wall element and a third wall element arranged adjacent to the first opening, the second and third wall elements extending in the direction of the longitudinal axis, each of the second and third wall elements having an inner wall and an outer wall extending substantially in the direction of the longitudinal axis, each of the inner walls and outer walls including an angle between 20° and 160° with one of the first and second side walls of the first wall element, the first opening of the deflection surface being arranged between the inner walls of the second and third wall elements, a second opening arranged outside one of the outer walls of one of the second and third wall elements, the second opening being disposed on the deflection surface at a side facing the second side wall of the first wall element, a first wall element of a second installation body adjoining the second and third wall elements, the first installation body being connected to the second installation body via a common bar element; and at least two separation elements connected to the bar element, the separation elements being located next to one another with respect to the longitudinal axis of the mixing element, and being formed as a projection extending only partially circumferentially around an inner wall of the mixer housing, each separation element of the separation elements defining a plane that is substantially perpendicular to the bar element. ### Claim 2 (depends on 1) The mixing element in accordance with claim 1, wherein each of the separation elements is formed as one of a strip and a rib having an angle, at least partly, of more than 45° with respect to the longitudinal axis of the mixer. ### Claim 3 (depends on 1) The mixing element in accordance with claim 1, wherein each of the separation elements is one of a strip and a rib. ### Claim 4 (depends on 1) The mixing element in accordance with claim 1, wherein a free cross-sectional area of the mixer housing is reduced by 5 to 12.5% by the separation elements. ### Claim 5 (depends on 1) The mixing element in accordance with claim 1, wherein a wall thickness of each of the separation element differs by a maximum of 10% of a mean wall thickness of one of the wall elements and the deflection elements. ### Claim 6 (depends on 5) The mixing element in accordance with claim 5, further comprising the plurality of separation elements are arranged along the longitudinal axis of the mixing element such that a distance between adjacent pairs of separation elements is not equal to a distance between subsequent pairs of adjacent separation elements. ### Claim 7 (depends on 1) The mixing element in accordance with claim 1, wherein each of the separation elements is one of a strip and a rib extending at least partly at an inner wall of the bar element. ### Claim 8 (depends on 7) The mixing element in accordance with claim 7, wherein the deflection element is one of a plurality of deflection elements, the bar element is one of a plurality of bar elements, and each of the separation elements is a strip extending from a respective bar element to a respective deflection element. ### Claim 9 (depends on 1) The mixing element in accordance with claim 1, wherein each of the separation elements has an arm projecting into the mixer space. ### Claim 10 (depends on 8) The mixing element in accordance with claim 8, wherein each of the separation elements is connected to the respective bar element and to the respective deflection element. ### Claim 11 (depends on 8) The mixing element in accordance with claim 8, wherein a first bar element and a second bar element of the plurality of bar elements are connected to one another via one of the separation elements. ### Claim 12 (depends on 1) The mixing element in accordance with claim 1, wherein the second installation body has the first wall element extending in the direction of the longitudinal axis, the second installation body having a first side wall and a second side wall arranged opposite the first side wall, a deflection element being arranged adjacent to the first wall element and the deflection element having a deflection surface extending in the transverse direction to the wall element at both sides of the wall element, the deflection surface of the second installation body having a first opening at a side of the deflection surface facing the second side wall of the wall element, a second wall element and a third wall element being arranged adjacent to the first opening and extending in the direction of the longitudinal axis, each of the second and third wall elements having an inner wall and an outer wall extending substantially in the direction of the longitudinal axis, each of the inner walls and outer walls including an angle between 20° and 160° with the first or second side walls of the first wall element, the first opening of the deflection surface being arranged between the inner walls of the second and third wall elements and a second opening being arranged outside one of the outer walls of the second or third wall elements, the second opening is provided in the deflection surface of the second installation body at side facing the second side wall of the first wall element, the second installation body containing the first wall element, the deflection element and the second and third wall elements being rotatably arranged about the longitudinal axis by an angle between 10° and 180° with respect to the first installation body. ### Claim 13 (depends on 12) The mixing element in accordance with claim 12, wherein the second installation body has the same structure as the first installation body. ### Claim 14 (depends on 12) The mixing element in accordance with claim 12, wherein the bar element is arranged at an outer periphery of the deflection element. ### Claim 15 (depends on 4) The mixing element in accordance with claim 4,
