Abstract
Official abstract text for this publication.
In a pressure controller for adjusting a pressure in a container connected downstream of the pressure controller and in fluid communication therewith, the pressure controller includes a main fluid duct having a fluid input and a fluid output leading to the container and a control valve for adjusting a fluid pressure at the fluid output, a bypass duct branching off from the main fluid duct downstream of the control valve, configured for venting of the main fluid duct, and a flow cross-section of the bypass duct being smaller than a maximum flow cross-section of the main fluid duct.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pressure controller and a container connected downstream of the pressure controller and in fluid communication with the pressure controller, wherein the pressure controller includes a main fluid duct having a fluid input and a fluid output leading to the container and includes a control valve for adjusting a fluid pressure at the fluid output, wherein the pressure controller further includes a bypass duct branching off from the main fluid duct downstream of the control valve, configured for venting of the main fluid duct, and wherein a maximum flow cross-section of the bypass duct is between 0.1% and 10% of a maximum flow cross-section of the main fluid duct. 2. The pressure controller and container according to claim 1 , wherein the pressure controller includes an electromagnetically actuatable vent valve, the flow cross-section of the bypass duct being adjustable by the vent valve. 3. The pressure controller and container according to claim 1 , wherein the pressure controller includes a control unit for controlling the control valve, the control unit being configured to adjust an output pressure at the fluid output to a desired value by appropriately controlling the control valve. 4. The pressure controller and container according to claim 1 , wherein the pressure controller comprises a pressure sensor which is arranged downstream of the control valve and in fluid communication with the main fluid duct to measure an actual pressure in the main fluid duct downstream of the control valve. 5. The pressure controller and container according to claim 2 , wherein the pressure controller includes a control unit for controlling the control valve, the control unit being configured to adjust an output pressure at the fluid output to a desired value by appropriately controlling the control valve. 6. The pressure controller and container according to claim 1 , wherein the pressure controller includes a carrier plate in which the main fluid duct extends, and a housing cover placed on the carrier plate, the housing cover together with the carrier plate limiting an electronics chamber of the pressure controller. 7. The pressure controller and container according to claim 6 , wherein the housing cover has electrical interfaces of the pressure controller arranged thereon. 8. The pressure controller and container according to claim 1 , wherein the pressure controller is formed as a piping-free system. 9. The pressure controller and container according to claim 1 , wherein the vent valve is formed as a control valve.
