Abstract: A dispenser for dispensing liquid product in fine droplet form in compressed air. The dispenser has an air compressing piston cylinder means mounted on the body including a fixed member and a movable member movable relative to the fixed member through a compression stroke to compress the air, and has a valve member normally obturating a compressed air flow path to a nozzle which is opened by actuating pin means operatively associated with the movable member of the air compressing piston cylinder means and the valve member near the end of the compression stroke only when the air compressing piston cylinder means has compressed air to a predetermined pressure. A product container means for a liquid product forms part of the dispenser and a product pressurizing piston cylinder means is provided for pressurizing the product. The movable member of the product pressurizing piston cylinder means is coupled to the valve member for movement substantially simultaneously with the movement of the valve member by the actuating pin means for pressurizing the product. Product valve means is provided in the product flow path between the product pressurizing piston cylinder means and the nozzle means and which is opened at substantially the same time as the product pressurizing piston cylinder means pressurizes the product.
