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.
Claims14
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 radial through opening, which is arranged in such a way that fluid can flow through the at least one radial through opening to the valve, and furthermore comprises a first 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 at least one radial through opening is formed by the first and second part, wherein the first filter device is arranged in the at least one radial through opening between the first part and the second part, wherein the valve cartridge comprises an axial through opening that is formed by the first and second part and has a second filter device, wherein the first part has webs supporting the second filter device.
A method for manufacturing a valve cartridge for accommodating a valve, comprising:
- manufacturing a first part of the valve cartridge having a first radial opening and a first axial opening,
- manufacturing a second part of the valve cartridge having a second radial opening and a second axial opening that are closed with a first and a second filter device, respectively,
- connecting the first and second part in such a way that the first and second radial openings in the valve cartridge together form a radial through opening through the first and second part, and the first filter device for the radial through opening is arranged between the first part and the second part and the first and second axial opening together form an axial through opening through the first and second part, wherein the first part has webs supporting the second filter device.
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 radial through opening, which is arranged in such a way that fluid can flow through the at least one radial through opening to the valve and furthermore comprises a first 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 at least one radial through opening is formed by the first and second part, wherein the first filter device is arranged in the at least one radial through opening between the first part and the second part, wherein the valve cartridge comprises an axial through opening that is formed by the first part and second part and has a second filter device, 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, wherein the first part has webs for supporting the second filter device.
