Valve assembly and apparatus for dispensing flowable materials

摘要

A valve assembly (8) for dispensing a plurality of flowable materials, such as viscous fluids or powders, comprising a valve member (9) having a plurality of inlets (11) for the plurality of flowable materials and dispense outlets (12) communicating with the inlets (11) and a closure (13) having one or more openings (16) in a pattern that corresponds to the pattern of at least some of the outlets (12). The valve member (9) and the closure (13) are movable relative to each other between a closed position in which the outlets (12) are closed and at least one dispensing position in which one or more openings (12) in the closure are at least partially in register with the dispense outlets (16) thus clearing the latter.
