Abstract:
An arrangement in fluid jet printers for ejection of a fluid in the form of droplets on a recording medium so as to generate characters thereon, such as bar codes (2), comprises a housing wall in which are formed a number of holes for reception in each one thereof of a valve body, a valve plate connected to the housing wall and formed with fluid passageway apertures in front of and in alignment with the valve bodies, said valve bodies sealingly cooperating with valve seats surrounding the apertures, and a nozzle plate (10) connected to the valve plate and provided with fluid channels the ends of which are positioned in front of the fluid passageway apertures, some of said fluid channels being branched off so as to form branch channels, the free ends of which are connected to jet nozzles directed towards the recording medium.
Abstract:
Arrangement for a valve (2) intended for the discharge of a high-viscosity medium (3), which valve comprises a regulator arrangement (4) for a valve body (5) capable of connection to an outlet (6). A fluid supply passageway (7), which is separate from the receiving space (9) for said medium, leads to the outlet (6), by means of which passageway distinct interruptions can be achieved in the medium (3) distributed from the valve (2) thanks to the presence of a fluid-containing accumulation in the medium (3), for example an air bubble.
Abstract:
An arrangement (1) for a liquid supply channel (5) for deflecting the flow before it is discharged via an outlet channel (3) in a liquid jet printer. The arrangement permits the smooth deflection of a liquid flow between two liquid channels situated in a liquid jet printer. The liquid supply channel (5) extends tangentially to the outlet channel (3).
Abstract:
The present invention relates to an arrangement (1) for a valve assembly which acts with a movable valve body (4), such as a piston, for the purpose of feeding a liquid in a liquid jet printer, the valve assembly including a valve seat (5) which extends around a liquid discharge opening (6) and interacts with said valve body to form a seal. The invention permits, amongst other things, the simple production of components parts of the valve assembly, and also permits the accurate feeding of liquid from the liquid jet printer. Said valve seat (5) is made of a flexible material (5A) capable of interacting with the moving valve body (4).

Abstract:
La présente invention se rapporte à un agencement pour une soupape (2) destiné à décharger un milieu à indice de viscosité élevé (3), ladite soupape comprenant une unité de régulation (4) pour un corps de soupape (5) pouvant être relié à un orifice de sortie (6). Un passage d'amenée de fluide (7), qui est séparé de l'espace (9) recevant le milieu, conduit à l'orifice de sortie (6). Des interruptions distinctes peuvent être obtenues dans le milieu (3) distribuées depuis la soupape (2) au moyen de ce passage grâce à la présence dans le milieu (3) d'une accumulation contenant du fluide, constituée par exemple par une bulle d'air.
