SEALLESS MODULAR DISPENSER

摘要

Modular 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 which contains the product under pressure. Within the housing is a ball-type valve mechanism, A deformable diaphragm isolates the reservoir from the mechanism which actuates the valve to prevent undesirable entry of the product. The diaphragm may be of a number of shapes, depending upon the length of the stroke desired for the ball mechanism. 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 valve opening is adjustable in discrete increments.
