Abstract
A drench gun having at least one interacting bore and piston to define a variable volume working space, a liquid exit from the working space, a liquid inlet to said working space, and a dose adjustment mechanism to vary the volume swept by the piston to adjust the dosage delivered by the gun. The dose adjustment mechanism comprises a body plug formed in two halves having a passage extending longitudinally therethrough, a movable sleeve located in the passage to abut the piston to adjustably limit movement thereto, and an adjustor projecting into the sleeve and adapted to rotate around the axis thereof. The adjustor and body plug are adapted to engage the sleeve so that upon rotation of said adjustor said sleeve is moved along longitudinally relative to the piston.
