Claims (4)

1. Gegossenes Gehäuse aus insbesondere Kunststoff für fluidführende Vor­ richtungen, hauptsächlich für Kreiselpumpen, wobei das Gehäuse (1) wenigstens einen Einlaßkanal (4) und wenigstens einen Auslaßkanal (6) für ein Fluid aufweist, wobei wenigstens einer der Kanäle einen räumlich gekrümmten Verlauf hat, dadurch gekennzeichnet, daß der räumlich gekrümmte Kanal (4, 6) in Form einer Wendel mit gleichbleibender Steigung ausgebildet ist.1. Cast housing made in particular of plastic for fluid-carrying devices, mainly for centrifugal pumps, the housing ( 1 ) having at least one inlet channel ( 4 ) and at least one outlet channel ( 6 ) for a fluid, at least one of the channels having a spatially curved profile , characterized in that the spatially curved channel ( 4 , 6 ) is designed in the form of a helix with a constant slope. 2. Gehäuse nach Anspruch 1, dadurch gekennzeichnet, daß die Wendel (4, 6) eine zylindrische Wendel ist.2. Housing according to claim 1, characterized in that the helix ( 4 , 6 ) is a cylindrical helix. 3. Gehäuse nach Anspruch 1, dadurch gekennzeichnet, daß die Wendel (4, 6) eine konische Wendel von maximal einer vollen Windung ist.3. Housing according to claim 1, characterized in that the helix ( 4 , 6 ) is a conical helix of at most one full turn. 4. Gehäuse nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, daß der durch den Windungsverlauf der Wendel (4, 6) gebildete Strömungsweg des wendelförmi­ gen Kanales sich in seinem Strömungsquerschnitt von seinem gehäusefernen Ende in Richtung seines gehäuseinneren Endes stetig verkleinert.4. Housing according to claim 1, 2 or 3, characterized in that the flow path formed by the winding course of the helix ( 4 , 6 ) of the wendelförmi gene channel is steadily reduced in its flow cross-section from its distal end towards its inner end.
