Dispenser

A dispenser for dosed dispensing of at least two components received in a plurality of reservoirs, wherein the dispenser comprises:

• (a) a plurality of pumping devices, wherein a separate pumping device is assigned to each reservoir of the plurality of reservoirs, wherein the pumping devices are provided with an actuation device for axial displacement of plungers acting on pumping pistons of the pumping devices in order to dispense the at least two components from an output device connected to the plurality of reservoirs;
• and
• (b) a dosing device, wherein the actuation device acts on the plungers indirectly via the dosing device, and the dosing device is provided with a setting device that is actuatable to change a position of a transmission element acting on the plungers for setting a quantity ratio of the at least two components, wherein the setting device is rotated in order to set the quantity ratio of the at least two components, and the actuation device is rotated as well in order to axially displace the plungers of the pumping device,
• wherein the setting device of the dosing device has an adjusting housing that is rotatable about a longitudinal axis of a reservoir housing of the dispenser, wherein the plurality of reservoirs for receiving the at least two components and the pumping devices are received in the reservoir housing, and the transmission element is disposed in the reservoir housing so as to be rotationally fixed with respect to the adjusting housing and so as to be axially displaceable on a longitudinal axis of the adjusting housing for actuating the plurality of pumping devices, wherein the transmission element comprises a contact surface of an annular configuration or that is formed as a ring segment having a surface contour changing in shape along a circumference and that interacts with the pumping pistons of the plurality of pumping devices,
• wherein the actuation device for dispensing the at least two components has an actuating housing that is rotatable about the longitudinal axis of the dispenser relative to the adjusting housing, wherein the actuating housing is equipped with a guide arrangement that enables axial displacement of the transmission element, wherein a first guide device of the guide arrangement is formed in the actuating housing and interacts with a second guide device of the guide arrangement, wherein the second guide device is formed independently of the actuating housing, for converting a rotary movement of the actuating housing into an axial movement of the transmission element,
• wherein the second guide device has a guide section having an axially oriented guide slot and a pin arrangement positioned at the transmission element with at least one radial guide pin that penetrates through the guide slot and a contact end of the at least one radial guide pin interacts with the first guide device of the actuating housing, and
• wherein, for forming the second guide device, the guide section is connected to the reservoir housing in a rotationally fixed manner, and the pin arrangement comprises a guide ring having the at least one guide pin, and the transmission element is received in the guide ring so as to be rotatable and is connected to the adjusting housing in a rotationally fixed manner by a radial engagement device so that when the adjusting housing is rotated, a relative rotation of the adjusting housing is effected with respect to the guide section.
