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 union nut (10) accordingly in order to control the air supply to the outlet openings (14, 15) of the air cap (11) and therefore to influence the formation of the spray jet.

A spray gun for atomizing fluid with compressed air comprises a housing having a handle, an atomizer nozzle, a guide sleeve having a U-shaped cross section which engages in the atomizer nozzle and is supported in the housing, and a valve needle which can be operated by means of a trigger which is in a pivoting mounting. The valve needle is connected with the trigger in the area of the guide sleeve by means of a hinge pin. A seal disposed in the guide sleeve, the seal being located between a feed line and the hinge pin, with the valve needle being held in a movable arrangement in the seal.

An apparatus for the loosening of wallpaper or the like from a substrate by steam. The apparatus includes a steam generator and a working plate, the steam generator being connected to the working plate by a flexible steam hose. The working plate is formed as a steam bar, which includes a U-shaped housing to which a handle is attached. A cover plate or a side piece can be detachably joined to the housing at one or both ends of the housing. The cover plate or side piece is closed at the end opposite the housing, and by choosing to attach either a cover plate or a side piece to the housing, the working area provided by the working plate can be adjusted. The apparatus thus provides a tool which can be easily and quickly adapted to loosen wallpaper in a variety of situations, including making it possible to steam both entire sheets of wallpaper and small portions of wallpaper in small areas where access to the wallpaper is poor. To facilitate the attachment and detachment of cover plate or side piece, a resilient snap catch is formed on the housing, the snap catch interacting with a stop provided on the cover plate and side piece.

摘要:
An apparatus for loosening wallpaper by means of steam, consisting of a steam generator and a steam plate connected to the steam generator by a steam hose, in which the steam generator incorporates a boiler which is closeable by means of a cover provided with a carrying handle and containing an electrical heating element, the carrying handle provided on the cover being thermally separated from the cover. This embodiment ensures that if the apparatus is used correctly, an operator will not come into immediate contact with heated components or hot steam and burns and scalds will be avoided.
