Abstract
The control actuator in accordance with the invention comprises a first part with a first wall arrangement and a bottom that circumscribe an inflow volume. The first wall arrangement comprises at least one flow opening through which fluid from the inflow volume can flow. Furthermore, the control actuator comprises a second part with a second wall arrangement that is arranged so as to be adjustable along the first wall arrangement. As a result of this, the fluid flow through a flow opening can be gradually cleared or limited. Preferably, the bottom is arranged in such a manner that the bottom breaks a basic inflow direction Se into the inflow volume and shields the second part against inflow pressure surges.
Claims16
Control actuator (10), comprising
- a first part (24) with a closed bottom (16) as well as a first wall arrangement (12) having at least one flow opening (20, 22), wherein the bottom (16) and the wall arrangement (12) delimit an inflow volume (18),
- a second part (28) arranged outside the inflow volume (18) and a second wall arrangement (30) with at least two wall sections (32, 34), wherein the wall arrangement (30) is arranged so as to be adjustable along the first wall arrangement (12) in an adjustment direction in order to gradually clear or close the flow opening (20, 22) by means of the wall sections (32, 34), and
- an adjustment drive (50) that is connected to the second part (28) in order to move said second part in the adjustment direction (R).
