Stockholm 1940. Kuria Boktr. P. A. Norstedt & Mier 400089Patent claim: 1: o) Control device for centrifugal pumps, flats and the like with a, in cylindrical inlet space located in the immediate vicinity of the inlet to the machine's impeller, whose geonietric shaft Egger in the extension of the impeller anal, oeh with an Over the inlet opening to this space pivotable control means, characterized in that the inlet space is provided with an inlet duct of such a shape that, when the control means is located in the position in which the inlet opening to the inlet space is slightly exposed, the channel protrudes substantially tangentially relative to the inlet space is set in such a way that the contents of this of the inflowing medium are continued in a rotation in the opposite direction to the direction of movement of the wheel. 2: o) Control device according to patent claim 1: o) for a pump or the like, in which the inlet duct has a rectangular cross-section, can be characterized in that a cradle (10) of the inlet duct of the inlet duct evenly intersects in the space of the inlet chamber (6) (6) circumferential cradle (1), while the opposite cradle (11) of the channel extends in the direction of or approximately towards the geometric axis of the room (6). 3: o) Control device according to patent claims 1: o) and 2: o), characterized in that the control means is constituted by a tongue, which with its one breath is pivotally mounted at the side cradle (10) of the inlet channel around a geometric with the space (6). axis parallel, stations pin (14), while the other spirit of the tongue is free and Iran is swung after a bag concentric with said pin frail a layer adjacent to the side cradle (10) to a layer adjacent to this cradle (10) opposite side cradle (11). 1: o) Control device according to patent claims 2: o) and 3: o), can be characterized by the fact that between it. The side cradle (11) and the circumferential cradle (1) of the space (6) directed towards the geometric axis of the space (6) are arranged, a cradle (12) passing tangentially in said circumferential cradle, the tongue (13) being so challenged that it extends in a rod position. substantially parallel to the oak lies with its free spirit against this cradle (12) near the latter side cradle (11).
