Abstract

The invention relates to a device for transmitting energy to a fastener, with a reaction chamber, an energy-transmission element that can move in a fastening direction for transmitting energy released in the reaction chamber to a fastener, a first supply channel opening into the reaction chamber for feeding a first reagent to the reaction chamber, wherein the first supply channel comprises a feeder device with a rotor and a feeder element for feeding the first reagent into the reaction chamber.

First claim

The invention claimed is:

1. A device for transmitting energy to a fastener comprising a reaction chamber, an energy-transmission element for transmitting energy released in the reaction chamber to a fastener, wherein the energy-transmission element can move in a fastening direction, wherein the energy-transmission element is oriented in the fastening direction with an energy-receiving face adjacent to the reaction chamber and an energy-discharge face, and a first supply channel opening into the reaction chamber for feeding a first reagent to the reaction chamber, wherein the first supply channel comprises a feeder device for feeding the first reagent into the reaction chamber and compressing the first reagent in the reaction chamber, and wherein the feeder device comprises a stator, a rotor having a rotational axis, and a feeder element for rotatingly moving the first reagent, wherein the feeder element is locked on the rotor.

2. The device according to claim 1 , comprising a rotary drive having a rotational axis for the rotor.

3. The device according to claim 2 , wherein the rotational axis of the rotor and/or the rotational axis of the rotary drive is oriented in the fastening direction.

4. The device according to claim 1 , further comprising a second supply channel for feeding a second reagent to the reaction chamber.

5. The device according to claim 4 , wherein the second supply channel opens into the reaction chamber.

6. The device according to claim 4 , wherein the second supply channels opens into the first supply channel.

7. The device according to claim 6 , wherein the second supply channel opens into the first supply channel upstream of the feeder device viewed in the direction of flow of the first reagent.

8. The device according to claim 6 , wherein the second supply channel opens into the feeder device.

9. The device according claim 6 , wherein the second supply channel opens into the first supply channel downstream of the feeder device viewed in the direction of flow of the first reagent.

10. The device according to claim 4 , wherein the first supply channel and/or the second supply channel has an inlet opening for surrounding air.

11. The device according to claim 4 , comprising a receptacle for a reagent reservoir adjacent to the first supply channel and/or to the second supply channel.

12. The device according to claim 1 , wherein the first supply channel comprises a closing device for closing the first supply channel, wherein the closing device can be opened and closed.

13. The device according to claim 1 , wherein the feeder element is arranged on the rotor so that it can move in the radial direction.

14. The device according to claim 2 , wherein the device comprises a control device for controlling the feeder device and/or the rotary drive.

15. The device according to claim 2 , wherein the first supply channel comprises a closing device for closing the first supply channel, wherein the closing device can be opened and closed.

16. The device according to claim 15 , wherein the device comprises a control device for controlling the feeder device, the rotary drive, and/or the closing device.

17. The device according to claim 1 , comprising a rotary drive having a rotational axis for the rotor.

18. The device according to claim 2 , further comprising a second supply channel for feeding a second reagent to the reaction chamber.

19. The device according to claim 3 , further comprising a second supply channel for feeding a second reagent to the reaction chamber.

20. The device according to claim 1 , wherein the feeder device comprises a screw-type compressor, a screw-spindle pump, a hose pump, a scroll compressor, or a rotary piston pump.
