Alternatively, however, the cleaning chamber 20 may have any cross-sectional shape, for example, the cross section may be approximately circular, oval, quadrangular, be formed trapezoidal or polygonal and each having an upwardly open section area. For example, it may be at the

Cleaning chamber 20 by a continuous, chamber, continuous cycle or

Diving facility act.

Furthermore, the cleaning chamber 20 may have at least one opening on one of the two end faces 2 ', 2 "which is closable, for example, by a closure lid which is not shown in greater detail on the respective end face 2', 2", so that an open top is closed , trough-like cleaning chamber 20 is formed for receiving a cleaning and / or rinsing medium. Preferably, an opening can be provided on each end face 2 ', 2 ", and in this case the opening

Cleaning chamber 20 on both sides with a dense the respective opening

be equipped closing cap. The respective closure lid can be designed, for example, by means of a pneumatic device sealing against the corresponding opening, in particular liquid-tight, hinged.

The workpiece carrier 23 provided in the cleaning chamber 20 is designed to receive at least one workpiece or machine component 22 or the like which is to be sucked off. This can, for example, by an arrangement of several support elements / recordings or a receiving basket and / or

Receiving container, preferably a grid box may be formed, wherein the

Receiving basket and / or the receptacle for receiving present in the form of bulk material workpieces or machine parts is provided. The workpiece carrier 23 can preferably be provided in the cleaning chamber 20 in a rotatable and / or pivotable manner by means of a rotary arrangement 24. The

Rotating assembly 24 may, for example, by two interconnected

preferably 360 ° degrees are movably attached to each other and thus a

three-dimensional turning / pivoting of the received workpiece carrier 23 allow. The rotational mobility of the guide elements 24 ', 24 "is indicated by corresponding arrows in Figure 1. For example, the guide elements 24', 24" of the rotary assembly 24 for their respective rotational mobility can be controlled independently by means of continuously pulse-controlled servo valves. Alternatively, it is also possible for the workpiece or machine component 22 on a linear unit 27, which is in particular formed horizontally and / or vertically movable within the cleaning chamber 20 to introduce. Again, alternatively, it is possible to clean the workpieces or

Do not introduce machine component 22 on the workpiece carrier 23 in the cleaning chamber 20, but to attach directly to the rotating assembly 24 by means of appropriate brackets or fixing pins and bring with the rotating assembly 24 in the cleaning chamber 20.

For introducing the workpieces or machine components 22 to be cleaned into the cleaning chamber 20, a cleaning system conveyor 25 may be provided, which may be designed, for example, as a belt and / or chain conveyor and which is adapted to engage the workpiece carriers 23 in and at least in the at least one cleaning chamber 20 / or contrary to a transport direction in a timed and / or defined constant transport speed to promote, so to move.

It can be provided that in particular the suction unit 1 within the

Cleaning chamber 20 fixed, that is stationary, is arranged, and the

be sucked workpiece or machine component 22 to the suction unit 1 is provided relatively movable by the workpiece or machine component 22nd

For example, on the cleaning system conveyor 25 and / or the

Workpiece carrier 23 and / or the rotary assembly 24 and / or the linear unit is arranged. Advantageously, the suction unit 1 above the

Cleaning plant conveyor 25 may be provided and the workpiece or machine component 11 within the cleaning chamber 20 on at least one

Workpiece carrier 23 are moved below the suction unit 1. Alternatively, it is also possible, the workpiece or machine component 11 by means of

Suction unit 15 to suck, in particular by suction unit 1 ... Γ "" manually, ie manually, is performed.

Again alternatively, the suction system 15, in particular the suction unit 1 can be automatically guided or moved by the suction unit 1...

For example, is arranged on a guide and movement device 26, by means of a controlled guidance and / or movement, in particular the suction unit. 1 he follows. For example, the suction unit 1 can be arranged on a guiding and moving device 26 which is designed as a robot kinematics having a plurality of rotating and / or moving axes, which has a plurality of

Robot arms 26.1 which are each rotatably or pivotally connected to each other about an axis of rotation 26.2.

According to a further preferred embodiment, the suction unit 1 is arranged on a guide and movement device 26, which is designed as a pivotable about at least one axis, preferably a vertical axis pivoting arm, in such a way that the suction unit 1 by means of the pivot arm in a to the outer contour of the workpiece or machine component 22, preferably in parallel spanned plane at least partially over the outer contour of the workpiece or machine component 22 can be pivoted. FIG. 10 shows, in a schematic cross-section, a front view of a further embodiment of an intake system 15 with a suction unit 1 according to the invention. In this case, a plurality of suction units 1 are provided, which surround the workpiece or machine component 22 at least partially, such that at least the top and bottom and the two longitudinal or broad sides of the workpiece or machine component 22 each have a suction unit 1 according to the invention is associated with corresponding suction 7 , The individual suction units 1 are connected to each other via Saugluftführungselemente 6. To initiate a suction flow, a suction device 16 is provided, which may be arranged, for example, on the upper side of the cleaning chamber 20. In this case, the workpiece or machine component 22 on the linear unit 27, in particular the horizontal and / or vertically movable within the cleaning chamber 20th
