Injection gun (spray gun) for injecting (spraying) liquid or plastic materials |
摘要 |
The injection gun has a housing (1) with a handle (2) and an attachment (3) for connection to a tank for material to be sprayed (injected). On the front part of the housing (1) there is attached a nozzle arrangement (8) which contains a tube (12) which is flexible essentially without kinking, a nozzle head (13) and a protective jacket (14) surrounding the tube (12). In the nozzle arrangement (8) there is arranged a nozzle needle-valve (17) which is flexible essentially without kinking and extends from the nozzle orifice to the nozzle head (13) and through a connection part (5). In the attachment there is mounted a non-return valve (27) so that a chamber closed with respect to the atmosphere is produced between the nozzle orifice and the non-return valve (27) to prevent reaction of the material to be injected with the ambient air. This injection gun is suitable for foam-filling cavities. To carry out surface coating, a second nozzle arrangement may be fitted on the injection gun to obtain an atomisation effect by means of compressed air which is fed via the handle (2). <IMAGE> |
