## Abstract

A valve cartridge for insertion into a valve block for a manifold valve for accommodating a valve in the valve cartridge includes at least one through opening for the passage of fluid flowing to the valve and a filter device for filtering the fluid. The valve cartridge includes a first part and a second part, which are interconnected in such a way that the through opening is formed by the first and second part, the filter device being arranged between the first part and the second part.

## Claims

### Claim 1

A valve cartridge for insertion into a valve block for a manifold valve, which is adapted to accommodate a valve, wherein the valve cartridge comprises:
at least one through opening, which is arranged in such a way that fluid can flow through the through opening to the valve, and furthermore comprises a filter device, which is adapted to filter the fluid, wherein the valve cartridge comprises a first part and a second part, which are interconnected in such a way that the through opening is formed by the first and second part, wherein the filter device is arranged in the through opening between the first part and the second part.

### Claim 2 (depends on 1)

The valve cartridge according to claim 1, wherein the first part is at least partly accommodated in the second part and the filter device is arranged in the second part at a side of the second part, which faces the first part.

### Claim 3 (depends on 2)

The valve cartridge according to claim 2, wherein the filter device in the second part is injection-molded on a side of the second part, which faces the first part.

### Claim 4 (depends on 1)

The valve cartridge according to claim 1, wherein the through opening is a radial through opening.

### Claim 5 (depends on 1)

The valve cartridge according to claim 1, wherein the valve cartridge comprises several of the through openings as well as further through openings, which are arranged in such a way that fluid can flow through the through openings to the valve and are respectively assigned to a particular port of a valve to be accommodated, and the first and second part of the valve cartridge are interconnected in such a way that through openings that are assigned to different ports of the valve are mutually sealed.

### Claim 6 (depends on 1)

The valve cartridge according to claim 1, wherein the first part and the second part of the valve cartridge are laser-welded to each other.

### Claim 7 (depends on 1)

The valve cartridge according to claim 1, wherein the valve cartridge comprises at least three through openings and is adapted to accommodate a 3/2 directional control valve.

### Claim 8 (depends on 1)

The valve cartridge according to claim 1, wherein the filter device comprises a strainer.

### Claim 9 (depends on 1)

The valve cartridge according to claim 1, comprising:
a valve arrangement having an electromagnetically actuated valve having at least one fluid port, wherein the valve is accommodated in the valve cartridge in such a way that each port of the valve has assigned thereto at least one through opening of the valve cartridge.

### Claim 10 (depends on 9)

The valve cartridge according to claim 9, wherein the valve is a 3/2 directional control valve.

### Claim 11

A method for manufacturing a valve cartridge for accommodating a valve, comprising:
manufacturing a first part of the valve cartridge having a first opening, manufacturing a second part of the valve cartridge having a second opening that is closed with a filter device,
connecting the first and second part in such a way that the first and second opening in the valve cartridge together form a through opening through the first and second part and the filter device is arranged between the first part and the second part.

### Claim 12 (depends on 11)

The method according to claim 11, wherein the first part and the second part are manufactured by injection molding method.

### Claim 13 (depends on 12)

The method according to claim 12, wherein the connection of the first part and of the second part is effected by penetration laser welding method.

### Claim 14 (depends on 13)

The method according to claim 13, wherein the first part and the second part are laser-welded to each other at two radially circumferential places.

### Claim 15

A method for controlling a hydraulic system of a vehicle transmission, comprising:
controlling the hydraulic system with a valve cartridge for insertion in a valve block for a manifold valve, which valve cartridge is adapted to accommodate a valve, wherein the valve cartridge comprises at least one through opening, which is arranged in such a way that fluid can flow through the through opening to the valve, and furthermore comprises a filter device that is adapted to filter the fluid, wherein the valve cartridge comprises a first part and a second part, which are interconnected in such a way that the through opening is formed by the first and second part, wherein the filter device is arranged in the through opening between the first part and the second part, wherein the valve cartridge comprises a valve arrangement having an electromagnetically actuated valve having at least one fluid port, wherein the valve is accommodated in the valve cartridge in such a way that each port of the valve has assigned thereto at least one through opening of the valve cartridge.
