摘要： PROBLEM TO BE SOLVED: To provide an improved fluid jetting apparatus, and a method for cleanly maintaining a fluid jetting apparatus.
SOLUTION: A fluid jetting head surface includes one or more orifices 220 for jetting a fluid therethrough. The orifices are formed through a projecting ridge on the surface of a head 200. The air flows over the ridge and the orifices so as to eliminate dusts and the residue from the orifices. The air flow, the ridge shape and the vicinity of the materials for printing are provided and disposed so as to provide the air covering the orifices or the laminar flow of another gas. The ridge downstream side 253 from the orifices has an inclination gentler than the upstream side 251.

摘要： Un cabezal de impresión de inyección de tinta por impulso (10) que incluye una cámara solidaria (49) acoplada entre un suministro de tinta (72) y una cámara de tinta (48). El cabezal de impresión también incluye una válvula de comprobación (32). La cámara solidaria (49) atenúa las variaciones de presión de duración corta. La válvula de comprobación (32) evita el flujo inverso de tinta.

摘要： An improved fluid jet device and method of keeping a fluid jet head clean are provided. The face of the fluid jet head includes one or more orifices, through which fluid is jetted. The orifices are formed through convex ridges at the surface of head. In a preferred embodiment of the invention, the slope from the face to the orifice is either generally constant or decreasing, to provide the convex shape. In an embodiment of the invention, air is blown over the ridge and over the orifice, to keep dust and debris away from the orifice. The flow of air, the shape of the ridge and the proximity of material on which printing occurs can be constructed and arranged to provide laminar flow of air or other gas over the orifice. The downstream side of the ridge from the orifice can have a shallower slope than the upstream side. A vacuum port can be provided on the downstream side.
