ABSTRACT:
A nozzle for extruding cementitious material may include an outlet sized and configured to extrude the cementitious material, a material flow pathway configured to channel the cementitious material to the outlet, and a vibration-actuated valve interposed in the material flow pathway. The valve may include a plurality of spaced-apart plates configured to form a plurality of flow channels, and a vibration-generating device coupled to the plates and configured to controllable cause the plates to controllably vibrate. The vibration-actuated valve may be configured such that the cementitious material must flow through the channels formed by the plates in order to reach the outlet, The spacing between the plates and the surface of the plates may be in amounts which collectively cause the flow of the cementitious material though the plurality of flow channels to be blocked when the vibration-generating device is not vibrating, and the cementitious material to flow through the plurality of flow channels simultaneously when the vibration-generating device is vibrating.
