Abstract
A pneumatic system includes a first line, a second line, and a valve. The first line is configured to be connected to a container, and to convey a flow of gas from a source to the container. The second line is arranged co-axially with the first line and is in communication with gas in the container. The valve is connected in series with the first line, between the source and the container. Furthermore, the valve is in communication with the second line and is configured to control the flow of gas through the first line as a function of a characteristic of the gas in the container, as communicated by the second line.
Claims20
A pneumatic system, comprising:
- a first line configured to be coupled to a container, and to convey a flow of gas from a source to the container;
- a second line arranged co-axially with the first line and in communication with gas in the container;
- and
- a valve coupled in series with the first line, between the source and the container, wherein the valve is in communication with the second line and is configured to control the flow of gas through the first line as a function of a characteristic of the gas in the container.
The pneumatic system of claim 9, wherein the valve is a spool valve having a valve plug translatable upon an air bearing.
A pneumatic system, comprising:
- a first line configured to be coupled to a container, and to convey a flow of gas from a source to the container;
- a second line configured such that when the first line is coupled to the container, the second line is simultaneously placed in communication with gas in the container;
- and
- a valve coupled in series with the first line, between the source and the container, wherein the valve is in communication with the second line and is configured to control the flow of gas through the first line as a function of a characteristic of the gas in the container.
A pneumatic system, comprising:
- a first line configured to be coupled to a lower-pressure container, and to convey a flow of gas from a higher-pressure source to the lower-pressure container;
- a second line coupled to the first line and in communication with gas in the lower-pressure container, wherein the second line projects from an end of the first line such that when the first line is coupled to the lower-pressure container, the second line extends into the volume of the lower-pressure container;
- and
- a valve coupled in series with the first line, between the higher-pressure source and the lower-pressure container, wherein the valve is in communication with the second line and is configured to control the flow of gas through the first line as a function of a characteristic of the gas in the lower-pressure container.
