Abstract

The invention relates to a switch ( 1 ) for an operating material, comprising an inlet opening ( 3 ) for introducing an operating material into an inlet side ( 2 ), and several outlet openings ( 5 ) for discharging the operating material to an outlet side ( 4 ). An actuator ( 6 ) comprising a connecting channel ( 7 ) is arranged between the inlet side ( 2 ) and the outlet side ( 4 ), said actuator can be adjusted such that the connecting channel ( 7 ) can connect the inlet opening ( 3 ) to one of the outlet openings ( 5 ). Said actuator ( 6 ) consists of at least two parts ( 9, 10 ), and the connecting channel ( 7 ) is defined, at least in sections, by both parts ( 9, 10 ) of the actuator ( 31, 32, 33, 34 ).

First claim

What is claimed is:

1. A switch for an operating material, comprising an inlet opening for supplying an operating material at an inlet side, and a plurality of outlet openings for discharging the operating material at an outlet side, wherein an actuator having a connecting channel is provided between the inlet side and the outlet side, and is adjustable in such a way that an option for connecting the inlet opening to one of the outlet openings can be provided via the connecting channel, wherein the actuator is made up of at least two parts, each part will contact the operating material when the operating material is discharged, the connecting channel being defined, at least in areas, by both parts of the actuator.

2. The switch according to claim 1 , wherein the connecting channel is defined by at least one recess in one of the parts of the actuator.

3. The switch according to claim 1 , wherein the connecting channel is defined, at least in sections, by recesses in two adjoining parts of the actuator.

4. The switch according to claim 2 , wherein the recesses of both parts are mirror-symmetrical, at least in areas.

5. The switch according to claim 1 , wherein the recesses extend from a contact surface of the parts into at least one of the parts in a direction of extent, wherein the clearance of the recess from the surface in the direction of extent is constant or becomes smaller.

6. The switch according to claim 1 , wherein the actuator is rotatable about a rotational axis.

7. The switch according to claim 6 , wherein the contact surface of the parts extends in parallel to the rotational axis.

8. The switch according to claim 6 , wherein the rotational axis extends through the opening of the connecting channel at the side of the actuator facing the inlet side.

9. The switch according to claim 6 , wherein the connecting channel extends from the side of the actuator facing the inlet side to the opposite side of the actuator facing the outlet side, such that the distance of the connecting channel from the rotational axis increases, at least in areas.

10. The switch according to claim 1 , wherein the actuator has at least one pressure medium channel which opens into the connecting channel via a channel opening to be able to supply a pressure medium into the connecting channel.

11. The switch according to claim 2 , wherein the connecting channel is defined, at least in sections, by recesses in two adjoining parts of the actuator.

12. The switch according to claim 2 , wherein the recesses extend from a contact surface of the parts into at least one of the parts in a direction of extent, wherein the clearance of the recess from the surface in the direction of extent is constant or becomes smaller.

13. The switch according to claim 3 , wherein the recesses extend from a contact surface of the parts into at least one of the parts in a direction of extent, wherein the clearance of the recess from the surface in the direction of extent is constant or becomes smaller.

14. The switch according to claim 4 , wherein the recesses extend from a contact surface of the parts into at least one of the parts in a direction of extent, wherein the clearance of the recess from the surface in the direction of extent is constant or becomes smaller.

15. The switch according to claim 2 , wherein the actuator is rotatable about a rotational axis.

16. The switch according to claim 3 , wherein the actuator is rotatable about a rotational axis.

17. The switch according to claim 4 , wherein the actuator is rotatable about a rotational axis.

18. The switch according to claim 6 , wherein the actuator is rotatable about a rotational axis.

19. The switch according to claim 7 , wherein the rotational axis extends through the opening of the connecting channel at the side of the actuator facing the inlet side.

20. The switch according to claim 1 , comprising:
a rear plate disposed around the inlet opening, the rear plate having a face adjacent the actuator at the inlet side, the rear plate face defining a gap radially spaced from the inlet opening and extending circumferentially around at least part of the inlet opening;
a pressure medium channel disposed within the actuator and fluidly connected to the connecting channel and the rear plate gap.
