Abstract

A valve actuator for a valved container containing a pressurized fluid, the actuator comprising a mounting to attach the actuator to the container, and characterized by a post-expansion chamber in communication with the outlet of the actuator in which residual fluid remaining in the outlet after use can expand, and a separate suction chamber in communication with the outlet conduit via a suction opening to suck residual fluid back toward the expansion chamber.
