ABSTRACT:
A decoupled liquid delivery system positioned within a housing for dispensing a liquid from a liquid filled canister includes a cylinder having an inlet for receiving the liquid and an outlet for dispensing the liquid, a piston moveably engaging the cylinder for exerting pressure on the liquid when the piston is actuated, a compression spring connected to the piston and the housing, and a recoil spring connected to the piston and the housing to prevent the piston from moving prior to actuation. The piston is actuated by disengaging the recoil spring from the piston which allows the compression spring to exert a force on the piston, thereby enabling the piston to exert a pressure on the liquid within the cylinder and dispense the liquid from the outlet.
