Abstract
A hand operated piston displacement-type pump having a one-piece valve body retaining a removable cylinder and discharge tube, for dispensing prescribed portions of complex fluids, such as food products or liquids with suspended solids, at a desired point outside of a storage container. Valve ball control of the flow of the product is obtained with the combination of the precision channels in the valve body and in the bottom of the cylinder and discharge tube. The valve body includes structure necessary for seal and connection to allow the cylinder and discharge tube to be removed, without tools, for cleaning.
