Abstract: The invention relates to a cleaning apparatus for cleaning, in particular, electrical components with a gaseous cleaning medium, comprising a receiving device to which the component is fixed or fixable, a nozzle device with at least one nozzle element directed or directable at the component, and a holding device for said nozzle element, wherein at least one nozzle element is adapted to at least one contour of the component, in particular an outer contour or an envelope surface, as well as a pressurization device for acting upon the nozzle device with the cleaning medium, wherein at least one nozzle element of the nozzle device is exchangeably and, in particular, releasably fixable or fixed to the holding device, and wherein the cleaning apparatus comprises at least one drive device, which is in operative connection with the component and/or with the nozzle device, for achieving a relative movement of the component and the at least one nozzle element during the cleaning. The invention also relates to a method.

Abstract: The invention relates to a cleaning apparatus for cleaning, in particular, electrical components by means of a gaseous cleaning medium, comprising a cleaning chamber with an inner space and a wall arrangement enclosing same, a receptacle for the component in the inner space and a flow device for the cleaning medium, which comprises a pressurization device and comprises or forms at least one inlet into the inner space and at least one outlet from the inner space, wherein a pressure difference between the at least one inlet and the at least one outlet is providable by means of the flow device, and wherein the flow device is formed such that the cleaning medium forms a vortex flow at least in sections in the inner space from the at least one inlet to the at least one outlet.

Abstract: The invention relates to a cleaning apparatus for cleaning workpieces, comprising a workpiece receptacle, a rotary part drivable in rotation about a main axis by way of a drive device, at least one nozzle supporting part which is drivable in rotation about an axis of rotation different from the main axis and on which at least one nozzle is arranged or formed at a distance relative to the axis of rotation, via which nozzle the workpiece can be acted upon by a cleaning medium, a charge generating device having at least one electrode for electrostatic charging and/or discharging of the workpiece and/or of the cleaning medium, wherein the at least one nozzle supporting part is held for rotation on the rotary part or wherein the workpiece receptacle is held to or formed by the rotary part.

Abstract: Methods and apparatus to treat workpieces are disclosed. A disclosed example equipment is to treat a workpiece with a process fluid, where the workpiece has a workpiece body with at least one cavity that extends from a first opening to a second opening. The example equipment includes a line system for providing the process fluid, where the line system has at least one line duct with an adapter for connecting the line system to the at least one cavity, a process chamber to receive the workpiece in treatment, where the process chamber includes an outlet to discharge a process fluid that has been induced into the cavity, and a suction installation to generate negative pressure, where the suction installation is connected to the process chamber by a suction duct to suction the process fluid from a fluid vessel through the at least one line duct and the at least one cavity into the process chamber.

Abstract: Systems and methods to dry workpieces are disclosed. A disclosed example system for drying workpieces that have been applied with a liquid medium includes a workpiece receiving region to receive at least one workpiece to be dried, where the workpiece receiving region is implemented in a vacuum chamber that is closable in a relatively fluid-tight manner, and an evacuation device to evacuate the vacuum, where the evacuation device has a suction pump that is fluidly coupled on a suction side by a fluid line to the vacuum chamber. The workpiece receiving region is positioned in the vacuum chamber of a housing for enclosing a workpiece to be dried. The housing includes a housing wall with at least one passage opening for a gaseous fluid, where the housing has a suction connection, which is fluidly coupled by a suction device to a vacuum container that is ventable by a valve via the suction line to open and block the suction line to generate negative pressure at the suction connection.

Abstract: Methods and apparatus to clean and dry cavities are disclosed. A disclosed example tool apparatus includes an inner tube to provide a fluid to the cavity when the tool apparatus is positioned relative to the cavity, and an annular tube surrounding the inner tube, where the annular tube is fluidly coupled to a suction chamber and where the suction chamber is fluidly coupled to a vacuum vessel. The example tool apparatus also includes a valve disposed between the suction chamber and the vacuum vessel.
