Abstract: There is disclosed a system and dispensing unit for the controlled and metered dispensing of a liquid product, or of two or more liquid products, which should be combined in the right proportions only shortly before ultimate usage. The basic system, as disclosed, employs a single pressure source for pressurization of the liquid product and the pressurized dispensing of the liquid product from the dispensing unit, per se. In addition to the basic illustrated system, there are disclosed novel dispensing units which enables the dispensing of a uniform or proportioned amount of liquid upon each operation thereof. Further, these units are constructed so as to permit the dispensing of several different liquids simultaneously from the same unit, or the selected dispensing of the individual liquid.

Abstract: There is disclosed a novel dispensing unit and system for the controlled, metered dispensing of one or more liquid products. The unit which serves to provide an important part of the system is designed for use with an arrangement wherein pressurized liquid products are delivered to the unit for controlled, metered dispensing. The unit is characterized primarily by the employment of metering chambers defined partially by flexible diaphragms. In conjunction with each said chamber, there are provided an inlet and outlet passage arrangement and a valve arrangement for controlling the supply and discharge of liquid product from said metering chamber. The unit includes a selectively operable control arrangement provided for opening and closing the valving arrangement, and also alternately pressurizing and venting the metering chamber diaphram with respect to a pressurized medium. When pressurized the metering chamber diaphragm will move relative to the remainder of the metering chamber to expel a predetermined quantity of liquid product from said chamber. The liquid product thus expelled will correspondingly replace liquid product in the discharge passage of the unit and will ultimately result in dispensing of a similar quantity of product from the dispensing head or outlet ports for the unit.

Abstract translation: 公开了一种用于一个或多个液体产品的受控定量分配的新型分配单元和系统。 用于提供系统的重要部分的单元被设计用于将加压液体产品输送到单元以进行受控定量分配的装置。 该装置的特征主要在于使用由柔性隔膜部分限定的计量室。 结合每个所述室，设置有入口和出口通道布置以及用于控制从所述计量室供应和排出液体产品的阀装置。 该单元包括用于打开和关闭阀装置的选择性可操作的控制装置，并且还相对于加压介质交替地加压和排出计量室。 当加压时，计量室隔膜将相对于计量室的其余部分移动，以从所述室排出预定量的液体产品。 因此排出的液体产品将相应地替代单元的排出通道中的液体产品，并且最终将导致从用于该单元的分配头部或出口端口分出类似数量的产品。
