Abstract

A hydraulic distributor block for fluid guidance, having at least two port surfaces which each have at least one port opening. The port openings of the port surfaces are connected by a flow duct, with the flow duct having at least one bend which is continuously curved and the port surfaces being spatially separated from one another.

First claim

The invention claimed is:

1. A hydraulic distributor block for fluid guidance, comprising:
at least one first port surface defining at least one consumer port opening configured to connect to at least one consumer;
at least one second port surface defining at least one port opening, the at least one first port surface and the at least one second port surface being spatially separated from one another; and
at least one flow duct defined in the hydraulic distributor block and connecting the at least one port opening and the at least one consumer port opening, the at least one flow duct having at least one continuously curved bend.

2. The hydraulic distributor block according to claim 1 , wherein the flow duct has at least one bend of at least 180° and/or at least two bends of at least 90°.

3. The hydraulic distributor block according to claim 1 , wherein the at least one continuously curved bend is surrounded by material in one piece.

4. The hydraulic distributor block according to claim 1 , wherein the at least one first port surface and/or the at least one consumer port opening is configured to connect to the consumer directly, via a multistation plate, or via a base plate.

5. The hydraulic distributor block according to claim 1 , wherein:
a first flow duct of the at least one flow duct connects a first consumer port opening of the at least one consumer port opening to a first pump port opening of the at least one port opening, and
a second flow duct of the at least one flow duct connects a second consumer port opening of the at least one consumer port opening to a second port opening of the at least one port opening, the second port opening being a tank port opening.

6. The hydraulic distributor block according to claim 1 , further comprising:
at least one valve opening configured to receive a valve, the at least one valve opening connected to one or more flow ducts of the at least one flow duct.

7. The hydraulic distributor block according to claim 1 , further comprising:
at least one filter receptacle configured to at least partially receive a filter.

8. The hydraulic distributor block according to claim 7 , wherein the filter receptacle ( 34 ) is connected to a first flow duct of the at least one flow duct.

9. The hydraulic distributor block according to claim 1 , further comprising:
at least one detection opening configured to receive at least one of a sensor and a measurement device, the at least one detection opening connected to one or more flow ducts of the at least one flow duct.

10. The hydraulic distributor block according to claim 1 , wherein at least one surface of the at least one first port surface and/or of the at least one second port surface is inclined at an angle between 0° and 90° with respect to an adjacent surface.

11. The hydraulic distributor block according to claim 1 , wherein an outer basic shape of the distributor block is at least partly matched to at least one of (i) the at least one flow duct, (ii) a valve opening, (iii) a sensor opening, (iv) a measurement port, and (v) a filter receptacle.

12. A hydraulic assembly comprising:
a hydraulic distributor comprising:
at least one first port surface defining at least one consumer port opening configured to connect to at least one consumer;
at least one second port surface defining at least one port opening, the at least one first port surface and the at least one second port surface being spatially separated from one another; and
at least one flow duct defined in the hydraulic distributor block and connecting the at least one port opening and the at least one consumer port opening, the at least one flow duct having at least one continuously curved bend.

13. A method of producing a hydraulic distributor block comprising:
forming at least one consumer port opening in at least one first port surface, the at least one consumer port opening configured to connect to at least one consumer;
forming at least one port opening in at least one second port surface, the at least one first port surface and the at least one second port surface being spatially separated from one another; and
forming at least one flow duct in the hydraulic distributor block connecting the at least one port opening and the at least one consumer port opening, the at least one flow duct having at least one continuously curved bend.

14. The method according to claim 13 , further comprising:
providing a casting mold for an outer basic shape of the distributor block;
creating a core casting mold of a negative of the at least one flow duct by 3D printing;
assembling the casting mold and the core casting mold; and
casting in the casting mold around the core casting mold so as to form the at least one consumer port opening, the at least one port opening, and the at least one flow duct.

15. The method according to claim 13 , further comprising:
providing a casting mold for an outer basic shape of the distributor block;
creating the at least one flow duct from pipe parts;
arranging the at least one flow duct into the casting mold; and
casting in the casting mold around the pipe parts so as to form the at least one consumer port opening, the at least one port opening, and the at least one flow duct.

16. The method according to claim 13 , further comprising:
3D metal printing the hydraulic distributor block so as to form the at least one consumer port opening, the at least one port opening, and the at least one flow duct.
