Abstract:
A fluid injection apparatus for supplying a pressurized fluid to a permeable portion of a tree comprising:a receptacle receivingly engageable with the tree defining a chamber enclosing the permeable portion of the tree, the receptacle comprising an elastomeric member compressingly engageable against a portion of the tree extending into the chamber; a reservoir adapted for retaining a supply of the fluid in fluid communication with the chamber; a pump selectively transferring the fluid from the reservoir to the chamber, increasing the fluid pressure in the chamber; and a closure member operably coupled to the elastomeric member comprising an adjustment member selectively positionable between a first position and a second position, whereat the first position a portion of the fluid exits the chamber and enters the reservoir along a weepage flow path between the elastomeric member and the tree, and whereat the second position the chamber is substantially fluid tight between the elastomeric member and the tree.
