Claim Text:
1. A rotary valve body for a dispensing device that is arrangable in rotatable manner in a matching valve seat in the dispensing device, whereby the rotary valve body is rotationally symmetrical about the rotation axis of the rotary valve body at least within a region intended for the valve seat, and whereby at least one first sealing cam made of an elastic plastic material is arranged on the rotationally symmetrical jacket surface of said region and is raised above a radius of the rotationally symmetrical jacket surface such that the first sealing cam renders a circumference of the rotary valve body larger than an internal diameter of the valve seat, and whereby at least one feed-through is arranged in the rotary valve body and extends from a first opening in the rotationally symmetrical jacket surface of the rotary valve body in the region of the first sealing cam into a second opening in the rotationally symmetrical jacket surface of the rotary valve body, wherein the first sealing cam is arranged directly adjacent to the first opening at a distance from a front face of the rotary valve body that is the same distance as that between the first opening and the front face of the rotary valve body, wherein at least one second sealing cam made of an elastic plastic material is arranged on the rotationally symmetrical jacket surface and is raised above the radius of the rotationally symmetrical jacket surface such that the at least one second sealing cam renders the circumference of the rotary valve body larger than the internal diameter of the valve seat, and whereby at least a second feed-through is arranged in the rotary valve body, whereby the second feed-through extends from a third opening in the rotationally symmetrical jacket surface of the rotary valve body in the region of the second sealing cam into a fourth opening in the cover surface of the rotary valve body that is oriented outward with respect to the dispensing device, wherein the second sealing cam is arranged adjacent to the third opening at a distance from the front face of the rotary valve body that is the same distance as that between the third opening and the front face of the rotary valve body, wherein the first and second sealing cams are arranged to be diagonal with respect to each other and the first and third openings are arranged to be diagonal with respect to each other, wherein a first diagonal located between the first and third openings intersects a second diagonal located between the first and second sealing cams.
