In a spray gun (1) for spraying paint with a gun housing (2) provided with a handle (3) with a union nut (10) screwed onto it that holds an air cap (11) provided with offset outlet openings (14, 15) for compressed air, the union nut (10) is positively connected to the air cap (11) in a circumferential direction. This embodiment makes it possible for the spray jet to be set in a brief time and without difficulties without having to put up with getting dirty. It is merely necessary to turn the uni...

A method for producing a mist in a spray head (1), especially for fire-fighting purposes or for humidification of intake air, in which method a medium, preferably an extinguishing medium, is supplied under pressure into the chamber (2) of the spray head via an inlet (3) and through at least one first channel (4) into at least one nozzle (5), which comprises at least one channel zone (6) narrower in a direction transverse to the flow of medium and after that in the direction of flow of medium a c...

The invention relates to a spray head, preferably for extinguishing fire, comprising a frame (1""), an inlet (2"") and a passage (7""a, 7"") leading to at least one nozzle (6""a, 6""b) with an opening (3""a) including a first boring (4""a, 4""b) and a second boring (5""a, 5""b), the first boring comprising a first diameter and the second boring a second diameter. In order for the spray head to have a good efficiency and a very simple construction and to be able to deliver medium in the form of m...

A spray catheter includes a flexible member having a spray tip and a fluid path through the flexible member to the spray tip. The catheter can be deformable and may include a mechanism for varying the spray geometry of the spray tip.

An applicator for applying a multi-component bio-material including at least two containers. Both containers are held in a structure or oriented in a structure such that material contained in the containers can be expressed from oriented outlets simultaneously. The applicator includes a graspable member which allows the material to be expressed from all containers of the applicator substantially simultaneously. The applicator may be constructed such that a pre-selected and substantially differen...

A spray booth has an enclosure structure, a ventilation system and overhead lighting. An upper region of the structure defines an air inlet plenum. Air exits the inlet plenum into the work area of the booth through an array of filter elements. The resistance to airflow of the filter elements may be tuned to encourage non-uniform airflow in the workspace, and, in particular, to create a proportionately large inflow in a central region, and a flow near the walls. Part of the inflow may be located ...

The invention relates to a spray gun with a handle part (3) comprising a safety switch (6). A nozzle tube (1) is connected on one end of said handle and a feed line (2) is connected to the other end thereof. Said spray gun, which can be actuated in a contactless manner by means of an actuating element (5) and a switch surface (4), is characterised in that the switch surface (4) contains an emitting and receiving unit, whereby the active area thereof is disposed in the antenna field (8) of the sw...

A spray gun having a gun body; a nozzle assembly arranged on the gun body; a compressed air supply channel located in the gun body, controlled by a valve assembly, a regulator for adjusting the supply of the spray material, an actuating element for actuating the valve assembly) and the regulator and a pressure measuring device. A pressure measuring device, resistant to dirt, that contains a pressure sensor integrated into the gun body and is connected to the compressed air supply channel via a c...

A spraying apparatus for spraying liquid surface treatment material which includes a gas inlet, a liquid inlet and an outlet nozzle. The apparatus also has a needle valve for regulating the supply of surface treatment material to the nozzle. The needle valve is at least partially located within a gas outlet chamber and is adapted so as to cause minimal disruption to the gas flow from the gas inlet to the nozzle. To further aid gas flow efficiency, the gas supply passage is substantially straight...

The present invention relates to a spray head for spreading liquid or semi-liquid products, preferably foodstuff. A product feeder (5) is provided to feed or convey a product (2) through a feed conduit (3) from a product container (4) to the spray head (1) and spraying nozzles (18) are provided to spread the product (2) when it is discharged from the spray head (1). The spray head (1) comprises three separate members, namely an upper coupling member (7), a lower coupling member (8) and a nozzle ...
