Patent number: 9486617Abstract: A rotary valve body for a dispensing device is arrangable 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. At least one sealing cam is arranged on the rotationally symmetrical jacket surface of said region and is raised above the radius of the rotationally symmetrical jacket surface such that the sealing cam renders the circumference of the rotary valve body larger than the internal diameter of the valve seat. At least one feed-through is arranged in the rotary valve body and extends from a first opening in the rotationally symmetrical jacket surface into a second opening in the rotationally symmetrical jacket surface.Type: GrantFiled: September 17, 2013Date of Patent: November 8, 2016Assignee: Heraeus Medical GmbHInventors: Sebastian Vogt, Clemens Greiner, Rudolf Hein

Publication number: 20140077115Abstract: A rotary valve body for a bone cement dispensing device is arrangeable 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. At least one sealing cam made of an elastic plastic material is arranged on the rotationally symmetrical jacket surface of said region and is raised above the radius of the rotationally symmetrical jacket surface such that the sealing cam renders the circumference of the rotary valve body larger than the internal diameter of the valve seat. 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 sealing cam into a second opening in the rotationally symmetrical jacket surface of the rotary valve body.Type: ApplicationFiled: September 17, 2013Publication date: March 20, 2014Applicant: Heraeus Medical GmbHInventors: Sebastian Vogt, Clemens Greiner, Rudolf Hein
