A portable, handheld breath actuated inhalator, to aerosolize and distribute a
pressurised liquid, including a breath flow path defined between an air inlet (132)
and a mouthpiece (131) outlet, a container (30) for the liquid, an
aerosolizing element (115) for introducing the aerosolized liquid into the
breath flow path, a valve element (113) between the container and the aerosolizing
means for allowing fluid communication between the container and the aerosolizing
element, and an actuator to regulate the valve element. The actuator is mechanical
and is energized by the flow of inhaled air.
