Abstract
Disclosed is an applicator, and a handle for an applicator. The applicator has at least one barrel and a piston moveable within the at least one barrel to stroke between a variable first position and a second position. In use, movement of the piston towards the first position can draw a first fluid into the barrel, and movement of the piston towards the second position can force the first fluid out of the barrel. The barrel has at least one fluid inlet valve to allow the fluid to flow into the at least one barrel at least under action of the piston, and at least one fluid outlet valve to allow the first fluid to flow out of the at least one barrel at least under action of the piston. A handle has a piston actuator assembly, housed at least in part within a body of the handle, operable to move the piston towards the second position to dispense the first fluid from the applicator. The piston actuator has a first actuating component driven by a user operated handle to pivot and tension a first biasing component, a second actuating component held in position against a force of the first biasing component, a first trigger component that holds the second actuating component in place until a required force is reached by the first biasing component, or a second trigger component releases the first trigger component. The second actuating component is then released and driven by the force of the first biasing component to in turn drive the piston toward the second position. The movement of the first actuating component is independent of the stroke of the piston.
