Abstract

The invention relates to a device ( 1 ) for conveying an operating material, comprising a filling chamber ( 3 ) with an inlet ( 4 ) for filling the filling chamber ( 3 ) with the operating material, a conveying section ( 6 ) for conveying the operating material to an outlet ( 5 ), a transition element ( 7 ) between the filling chamber ( 3 ) and the conveying section ( 6 ) which can be switched between an open position and a closed position. The operating material which is introduced via the inlet ( 4 ) in the filling chamber ( 3 ), in the open position of the transition element ( 7 ), can be transferred in the conveying section ( 6 ) by means of a gaseous transport medium, and the operating material can be discharged from the outlet ( 5 ) from the conveying section ( 6 ) by means of a gaseous transport medium.

First claim

What is claimed is:

1. A device for conveying an operating material, the device comprising:
a head side opposing and physically separated from a base side,
an inlet in the head side of the device fluidly connected to a filling chamber,
a conveying section fluidly connected to the filling chamber and fluidly connected to an outlet,
a transition element disposed between the filling chamber and the conveying section, the transition element switchable between an open condition and a closed condition, and
an actuator physically displaceable between a first position and a second position to switch the transition element between the open condition and the closed condition, wherein the actuator in the first position is disposed between the base side and the outlet and the actuator in the second position is disposed between the outlet and the transition element,
wherein when the transition element is in the open condition a mixture of a first gaseous transport medium and the operating material can move through the inlet and the operating material can further move into the filling chamber, past the open transition element, through the conveying section and into the outlet.

2. The device according to claim 1 , wherein the first gaseous transport medium can be fed into the filling chamber for transporting the operating material into the conveying section, and a second gaseous transport medium can be fed into the conveying section for conveying the operating material away from the outlet.

3. The device according to claim 2 , wherein the first and the second gaseous transport medium can be simultaneously fed, at least intermittently, to the filling chamber and to the conveying section in the open position of the transition element in order to allow discharge of the operating material from the outlet by means of the first and also the second gaseous transport medium.

4. The device according to claim 1 , further comprising an exhaust air opening and a means for separating the gaseous transport medium from the operating material so that the operating material passes into the filling chamber and the gaseous transport medium flows through the means for separating and escapes through the exhaust air opening.

5. The device according to claim 4 , wherein the means for separating is situated between a feed section for a gaseous transport medium and the conveying section in such a way that the gaseous transport medium can alternatively flow through the means for separating to allow an option for the means for separating to be cleaned of operating material by the gaseous transport medium.

6. The device according to claim 4 , further comprising a storage chamber for the operating material for filling the filling chamber by means of a gaseous transport medium, wherein the exhaust air opening is fluidly attached to the storage chamber to optionally allow ventilating the operating material present in the storage chamber by the gaseous transport medium which is discharged through the exhaust air opening.

7. The device according to claim 4 , wherein a means for closing the exhaust air opening and/or the inlet is provided, wherein the means for closing has an actuator and is designed in such a way that the means for closing is able to close the exhaust air opening and/or the inlet by a motion of the actuator in the flow direction of the gaseous transport medium or in the direction opposite thereto.

8. The device according to claim 1 , wherein the actuator moves in a direction opposite to the transfer direction of the operating material from the filling chamber to the conveying section to switch the transition element to the closed position.

9. The device according to claim 2 , further comprising an exhaust air opening and a means for separating the gaseous transport medium from the operating material, wherein the mixture of first gaseous transport medium and the operating material is separated by the means for separating so that the operating material passes into the filling chamber and the gaseous transport medium escapes through the exhaust air opening.

10. The device according to claim 3 , further comprising an exhaust air opening and a means for separating gaseous transport medium from the operating material wherein the mixture of gaseous transport medium and the operating material is separated by the means for separating so that the operating material passes into the filling chamber and the gaseous transport medium escapes through the exhaust air opening.

11. The device according to claim 5 , further comprising a storage chamber for the operating material for filling the filling chamber by means of a gaseous transport medium, wherein the exhaust air opening is fluidly attached to the storage chamber to optionally allow ventilating the operating material present in the storage chamber by the gaseous transport medium which is discharged through the exhaust air opening.

12. The device according to claim 5 , wherein a means for closing the exhaust air opening and/or the inlet is provided, wherein the means for closing has an actuator and is designed in such a way that the means for closing is able to close the exhaust air opening and/or the inlet by a motion of the actuator in the flow direction of the gaseous transport medium or in the direction opposite thereto.

13. The device according to claim 6 , wherein a means for closing the exhaust air opening and/or the inlet is provided, wherein the means for closing has an actuator and is designed in such a way that the means for closing is able to close the exhaust air opening and/or the inlet by a motion of the actuator in the flow direction of the gaseous transport medium or in the direction opposite thereto.

14. The device according to claim 2 , wherein the actuator moves in a direction opposite to the transfer direction of the operating material from the filling chamber to the conveying section to switch the transition element to the closed position.

15. The device according to claim 3 , wherein the actuator moves in a direction opposite to the transfer direction of the operating material from the filling chamber to the conveying section to switch the transition element to the closed position.

16. The device according to claim 4 , wherein the actuator moves in a direction opposite to the transfer direction of the operating material from the filling chamber to the conveying section to switch the transition element to the closed position.

17. The device according to claim 5 , wherein the actuator moves in a direction opposite to the transfer direction of the operating material from the filling chamber to the conveying section to switch the transition element to the closed position.

18. A device for conveying an operating material, the device comprising:
an inlet in a head side of the device fluidly connected to a filling chamber,
a conveying section fluidly connected to the filling chamber and fluidly connected to an outlet, and
a transition element disposed between the filling chamber and the conveying section, the transition element movable between an open position and a closed position, and
a screen for separating the gaseous transport medium from the operating material so that the operating material passes into the filling chamber
wherein when the transition element is in the open position a mixture of a first gaseous transport medium and the operating material can move through the inlet and the operating material can further move into the filling chamber, past the open transition element, through the conveying section and into the outlet and
