The disclosure concerns an applicator (e.g. printhead) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having at least one nozzle row with a plurality of nozzles for dispensing the coating agent in the form of a jet in each case, the nozzles being arranged along the nozzle row and in a common nozzle plane, and having a plurality of actuators for controlled release or closure of the nozzles. The disclosure provides that the individual actuators each have an outer dimension along the nozzle row which is greater than a nozzle distance along the nozzle row.

A nozzle assembly is provided that includes two sections, the first section may be contoured and the second section may be a converging and diverging section that is downstream from the second section in the direction of gas flow. The contoured section, with a range of bend angles, allows for non-line-of-sight cold spray deposition, thereby providing location-specific control of the cold spray deposition process.

A pig system for transporting liquid or pasty substances two pig stations which are connected to one another by way of a pig line. The pig system includes a number of pigs. Accordingly, the two pig stations have a number of parking positions, to which a controllable media connection is respectively assigned. Appropriate activation of the media connections allows the effect to be achieved that only some of the pigs at a time shuttle back and forth between the two pig stations. Defective pigs or operational pigs that are being kept on standby in this case remain in corresponding parking positions of the two pig stations.

A spray nozzle that includes a nozzle body defining a first surface, a cap defining a second surface able to define an annular nozzle opening therebetween, a turbine having a plurality of radially extending fins circumferentially positioned about the nozzle opening for directing the flow of fluid exiting the nozzle opening, and a reverser member including a cup portion positioned below the cap to intercept the flow of fluid from a flow passage of the cap. The reverser member coupled to the turbine such that the reverser member is caused to rotate in response to rotation of the turbine.

A ball swivel of the configuration typically utilized for pool cleaners includes male and female portions featuring an interposed stopper to reduce friction and prevent the male and female portions from binding under load, while improving sealing and continuing to allow rotational and pivotal motion.

The disclosure relates to a painting system component, in particular a rotating bell (1) for a rotating atomizer, including a main body (1) and a surface coat (8) at least on a part of the surface of the main body (1). The surface coat (8) reduces the tendency of the painting system component to become dirty and/or improves the ease of cleaning of the painting system component.

Provided is a nozzle for jetting liquid in an accurate direction with respect to a nozzle mounting hole. The nozzle is mounted to a nozzle holder having a nozzle mounting hole having a right cylindrical shape, an outlet port connected to the nozzle mounting hole, and a mounting internal thread. The nozzle includes: a mounting external thread disposed at a first end, and is a parallel thread that fits with the mounting internal thread; a cylindrical portion that fits in the nozzle mounting hole; a first introducing passage disposed coaxially with the cylindrical portion; a cylindrical choke portion disposed coaxially with the cylindrical portion, and a conical portion connecting the first introducing passage to the cylindrical choke portion.

A swirl element for swirling fluid in a nozzle has a swirler body. The swirler body defines a feed channel including an axially oriented channel surface and a swirl chamber in fluid communication with the feed channel. The swirl chamber defines a radially oriented swirler surface substantially normal to the channel surface. The swirl chamber and the axially oriented channel are in fluid communication through a tangential slot for imparting swirl on fluids passing from the feed channel into the swirl chamber. The tangential slot includes a smoothly rounded surface transitioning from the channel surface to the swirler surface for providing a smooth, substantially separation free transition in fluid flow from the channel into the swirl chamber.
