ABSTRACT:
An improved fluent product dispenser in which the product is dispensed by means of compressed air has a dispenser body having a dispensing means therein for mixing and dispersing the fluent product and compressed air and has a piston-cylinder means thereon by which the air is compressed, and when it reaches a certain predetermined pressure, is suddenly released. The fixed member of the piston-cylinder means has a fluent product containing recess opening toward the movable member of the piston-cylinder means, and a product pressurizing piston in the product containing recess has an end exposed toward the movable member or the piston-cylinder means. A product control valve means controls the flow of product from the product containing recess to the dispensing nozzle through the body. Likewise, a compressed air valve opens to permit flow of compressed air through a compressed air path in the body to the nozzle when the compressed air reaches a certain predetermined pressure. A product valve actuator is coupled to the product valve and is mounted in a flexible diaphragm sealed at the edge thereof, and the compressed air flow path opens into the space beneath the diaphragm so as to open the product valve in a predetermined time relationship to the opening of the compressed air valve means, so that when the movable member of the piston-cylinder means is moved toward the fixed member for compressed air, the compressed air acts on the product pressurizing piston for pressurizing the product, and when the compressed air is released from the piston-cylinder means, it acts on the product valve actuator to actuate the product valve and releases the product only upon release of compressed air.
