Abstract: The present invention refers to a flush tank providing a receptacle with a discharge valve and a triggering mechanism therefore. A first end of an adapter (5) is inserted with a press fit into a discharge projection (3) of the receptacle (2) for the flush water. A discharge tube (7) to discharge the flush water from said receptacle (2) is attached to a second end of said adapter (5), wherein a triggering mechanism (8) is arranged within said tube (7), said mechanism releasing flow of the water out of said receptacle (2). The triggering mechanism comprises a body (16) in which a first hollow piston (22) is slidably arranged whereby lifting the first piston initiates a small flush. A second piston (25) is in turn slidably arranged in the first piston whereby lifting the second piston initiates a large flush. The pistons are both actuated pneumatically.

Abstract: A device for transforming a laminar fluid flow into drops, especially infusion fluids, comprises an inlet unit tightly placed into an intermediate unit. A cylinder of the inlet unit is, on its outer circumference, provided with a screw-shaped channel extending from a through-hole leading perpendicularly to the cylinder at its first side to the area of passage of the cylinder into a bottom at its second side. A step projecting radially inwards from the cylinder comprises, on its inner circumference, a number of longitudinally running grooves connected to a number of radially running grooves arranged on a flange of the intermediate unit. A levelling nut is screwed on a thread of a socket comprising a sealing screen which, with a transition fit, is placed between the cylinder of the inlet unit and the cylinder of the intermediate unit.
