    • An apparatus and method are disclosed to dispense a product out of a receptacle by moving a free-floating piston back and forth within the receptacle. Pressurized gas is used to move the piston toward the product, thereby forcing the product out of the receptacle. The pressure on the piston is released by exhausting the pressurized gas out of the receptacle through a release valve. To retract the piston away from the product, the pressurized gas is sent through a venturi that connects to the receptacle via the same aperture that is used to deliver the pressurized gas to the receptacle. The flow of pressurized gas through the venturi creates a vacuum in the receptacle that pulls the piston away from the product.
    • 公开了一种通过在容器内来回移动自由浮动活塞将产品从容器中分配出来的装置和方法。 加压气体用于将活塞朝向产品移动,从而迫使产品离开容器。 活塞上的压力通过排出阀将压缩气体排出容器而被释放。 为了将活塞缩回产品,加压气体通过文丘里管传送,该文丘里管通过用于将加压气体输送到容器的相同的孔连接到容器。 通过文氏管的加压气体流在容器中产生真空,将活塞拉离产品。
