Abstract
An irrigation system includes an activator that increases or decreases its weight respectively in response to an increase or decrease of pressure in the system. The activator biases a valve that controls the fluid pressure in the system.
Claims19
An irrigation system comprising an activator,
- the activator comprising a vessel and a tube that meet at a join,
- at least a section of the system holds fluid and the vessel is in fluid communication with the section via the tube, wherein
- a rise of fluid pressure in the section above a predetermined level urges fluid to flow via the join into the vessel to increase the weight of the vessel and move the vessel.
An irrigation system comprising a valve and an activator,
- at least a section of the system holds fluid wherein a rise of pressure in the section increases a weight of the activator which biases the valve to decrease a fluid passage therethrough.
An irrigation system assembly, comprising:
- a valve having a movable member configured to control a flow of fluid;
- a vessel mechanically coupled to the movable member of the valve;
- and
- a tube in fluid communication with the vessel, wherein:
- an increase in fluid pressure in the tube urges a fluid in the tube to flow into the vessel, thereby increasing a weight of the vessel and altering a position of the movable member of the valve.

An irrigation system, comprising:
- an irrigation pipe configured to deliver fluid to a crop in a field;
- and
- an irrigation system assembly comprising:
- a valve having a movable member;
- a vessel mechanically coupled to the movable member of the valve;
- and
- a first tube in fluid communication with the vessel, wherein:
- an increase in fluid pressure in the first tube urges a fluid in the tube to flow into the vessel, thereby increasing a weight of the vessel and altering a position of the movable member of the valve to thereby control fluid flow through the irrigation pipe.
