Abstract
Modular positive displacement apparatus for dispensing precise quantities of a fluid product including a dispensing unit and an actuator unit. A housing of the dispensing unit defines a reservoir, a chamber and closure valve. The reservoir is divided into a plurality of sub-reservoirs, which contains the product. The walls dividing the reservoir into a plurality of sub-reservoirs provide guide surfaces for self-alignment of a product piston in the reservoir. A deformable diaphragm isolates the reservoir from the mechanism which actuates the valve to prevent undesirable entry of the product. The dispensing unit is readily removable from the actuator unit and can be readily replaced with another dispensing unit. Different nozzle sizes can also be accommodated. The extent of the closure opening is adjustable in discrete increments.
