Paste application system having a two-component cartridge with two axially shiftable feed plungers; one hollow cylinder with an open front face and an at least partially closed front face, an axially mobile first plunger situated therein with two pestles attached to it; another hollow cylinder that contains a manually shiftable second plunger; and a liquid container, whereby the second hollow cylinder is connected or connectable to the liquid container in liquid-permeable manner by a first conduit means and a first non-return valve, and the first hollow cylinder is connected or connectable to the second hollow cylinder in liquid-permeable manner by a second conduit means and a second non-return valve; whereby the two-component cartridge and the first hollow cylinder, arranged axially adjacent, with the axially mobile pestles are arranged in a pressure container; and the paste application system contains a hollow space and liquid is present in said space.

Paste application system for the mixing of a paste made of two components

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.

Rotary valve body for bone cement dispensing device

A dispensing device dispenses flowable materials from cartridges, whereby the dispensing device comprises a base body, a connecting element for a gas cartridge on the base body, a valve element for controlling a gas flow from the gas cartridge, and a gas-permeable channel connecting the connecting element to the valve element. At least one evaporation container is arranged in the gas-permeable channel such that the gas flow from the gas cartridge is guided through the evaporation container, at least over regions thereof.
