1. A fluid distribution device comprising:
a distributor housing having at least one fluid inlet opening and at least one fluid outlet opening; and
at least one rotary, elongated hollow element having a wall that has one or more fluid-passage openings, wherein a fluid flow through the distributor housing is changed by rotating the at least one rotary, elongated hollow element, wherein the at least one rotary, elongated hollow element has a length that extends along its longitudinal axis, and wherein the wall of the at least one rotary, elongated hollow element has a plurality of axially spaced fluid-passage openings;
wherein the at least one rotary, elongated hollow element includes a first rotary, elongated hollow element and a second rotary, elongated hollow element, each having a wall that includes one or more of the one or more fluid-passage openings, wherein the fluid flow through the distributor housing can be changed by rotating the first, rotary elongated hollow element and the second rotary, elongated hollow element; and
wherein the distributor housing has at least one first fluid outlet opening and at least one second fluid outlet opening, wherein the fluid flow through the at least one first fluid outlet opening and the fluid flow through the at least one second fluid outlet opening can be individually controlled by rotating the first, rotary elongated hollow element and the second rotary, elongated hollow element
wherein in one operating condition, the fluid flow is configured to:
enter the distributor housing through the at least one fluid inlet opening;
enter the first rotary, elongated hollow element;
enter the second rotary, elongated hollow element;
be redirected in opposing lateral directions;
be redirected to re-enter the first rotary, elongated hollow element; and
exit the distributor housing through the at least one first fluid outlet opening.
