Pneumatic liquid-dispensing gun

Pneumatic liquid—dispensing gun, from among the means for dispensing liquids, essentially characterised by including:

• a central body (1) and a pneumatic body (2) with a prismatic shape and made of a lightweight material
• a pin (10) with a guide (6) and a conical point that rests on the inside of the nozzle (3), closing the outlet orifice
• a conical nozzle (3) that is attacked to the central body by a nut (4)
• a sealing bellows (5) made of an elastic material that is concentrically mounted on the pin (10) inside the central body (1)
• a pneumatic rod (9) with a small diameter that increases the speed of response and reduces the size of the pneumatic body (2)
• a flow regulator (8) that is partly housed on the inside of the pneumatic body (2), above which projects the graded ruler and the knurled cylindrical part, for a precise manual adjustment of the run of the pin (10), acting as a calliper in the fine adjustment of this run, with resistance to rotation being provided by a gasket (16), in addition having a safety spring (17) mounted on the inner diameter of this regulator (8) to achieve closure in the event of lack of external pneumatic pressure.
• an element (7) on which screws the flow regulator (8) and that is in turn blocked by the flange (12)
• four screws (11) joining the central body (1), the pneumatic body (2) and the flange (12), that facilitate the assembly and disassembly of the gun.
• the O-rings (13) and (14) providing tightness between the central body (1) and the pneumatic body (2)
• a dovetail (18) on the central body(1) for installation and adjustment both on machines and other devices.
