Abstract
A suction tube arrangement includes a suction tube having a suction tube opening and an actuating shaft which is received in the suction tube. The actuating shaft has a base body made of a first material and an actuating shaft body made of a second material and at least partially applied on the base body. The base body or the actuating shaft body forms at least one cover element to open or close the suction tube opening as a function of a rotation of the actuating shaft. An actuating element is at least partially enclosed by the actuating shaft body for actuating the actuating shaft.
Claims15
A suction tube arrangement, comprising
- a suction tube having a suction tube opening;
- an actuating shaft rotatable around a rotation axis and received in the suction tube, said actuating shaft having a base body made of a first material and an actuating shaft body which is made of a second material different from the first material and which is at least partially applied on the base body and forms at least one cover element to open or close the suction tube opening as a function of a rotation of the actuating shaft;
- and
- an actuating element for actuating the actuating shaft, wherein said actuating shaft body at least partially encloses the actuating element along its axial length from outside in a circumferential direction, wherein said actuating element comprises a recess configured to at least partially receive the base body, said actuating element having at least one region which at least partially circumferentially surrounds the base body of the actuating shaft.
A suction tube arrangement, comprising
- a suction tube having a suction tube opening;
- an actuating shaft rotatable around a rotation axis and received in the suction tube, said actuating shaft having a base body made of a first material and an actuating shaft body which is made of a second material different from the first material and which is at least partially applied on the base body and forms at least one cover element to open or close the suction tube opening as a function of a rotation of the actuating shaft;
- and
- an actuating element for actuating the actuating shaft, wherein said actuating shaft body at least partially encloses the actuating element along its axial length from outside in a circumferential direction, wherein the actuating element comprises at least one tongue-and-groove element engaging in the actuating shaft body.
