A compressed air-actuated valve means useful for attachment to devices used in chemical analysis wherein a piston actuates a suitably positioned slide member in the piston thrust direction. The slide member glides on a base member provided with spaced-apart holes that extend approximately perpendicular to the glide surface of the base member. The holes are connected to one another on the side of the base member facing the slide member via at least one appropriately arranged groove positioned in the slide facing the base member. Intake and discharge nozzl...
In a compressed air-actuated valve means for attachment to various devices, such as useful in chemical analyses, wherein a piston means actuates a slide member in the piston thrust direction and said slide member linearly glides on a base member having at least two spaced-apart apertures extending approximately perpendicularly to the gliding surface of said slide member, said apertures being connectable with one another on one side of said base member via at least one groove correspondingly arranged on a surface of said slide member and being connectable...
