ABSTRACT:
Dispensing apparatus for semi-fluid material includes a housing having a vertical bore and a second bore connecting with this vertical bore. A piston is slidably mounted within said second bore and is movable between a first position spaced from the vertical bore and a second position adjacent to the vertical bore. Fluid pressure is applied through a first channel to a first piston surface to cause the piston to move from a first to the second position. Fluid pressure is applied through a second channel to a second piston surface to cause the piston to move back to the first position from the second position. An input aperture connects the vertical bore in the housing to an interconnecting array of branching channels which are in turn connected through a plurality of apertures to dispensing members. The channels in this array are configured such that the pressure drop between the input aperture to the array and the inputs of each of the dispensing members is equal.
