Embodiment Construction

[0016] exist figure 1 The paint spray gun shown in includes a gun body 1 with a handle 2 and an upper body 3 on which a hook 4 is (integrated). A through hole 5 penetrating from front to back and forming multi-level steps passes through the upper body 3, and a spray needle 6 can move axially in the through hole. Through-opening 5 has a diameter-enlarged front region 7 into which an oblique inlet opening 8 with an internal thread 9 for screwing on a paint storage container (not shown) leads.

[0017] An internal thread 10 is provided at the front end of the through hole 5, and the paint nozzle 11 is screwed into the upper body 3 of the gun body 1 through this internal thread. Paint nozzle 11 contains a nozzle hole 12 on its front end, and it and can pass through the shrinkage of the spray needle 6 of a discharge trigger lever 13 axial movement or the front end of a tip together form a nozzle for paint, paint or the like. Adjustable entry. In order to move the needle through ...

Abstract

The invention relates to a paint spray gun with a paint nozzle placed on a gun body, an air nozzle placed around the paint nozzle, a compressed air valve placed within a piston borehole in the gun body, a compressed air borehole running through a handgrip of the gun body to the piston borehole, and a pressure-sensing and pressure display device placed in the hand grip. For sensing and displaying the spray pressure, a tube is placed in the compressed air borehole at a distance from its inner wall. The tube forms, in the interior, a channel for the compressed air supply to a part of the piston borehole placed upstream of the compressed-air valve, and borders an intermediate space between its exterior and the inner wall of the compressed air borehole. The intermediate space is connected via a first connecting channel with a pressure chamber placed downstream of the compressed-air valve and via a second connecting channel with a pressure gauge chamber in the handgrip allocated to the pressure-sensing and pressure display device.

Description

technical field [0001] The present invention relates to a paint spray gun (Farbspritzpistole), which has: a paint spray nozzle arranged on the gun body, an air nozzle arranged around the paint nozzle, a piston hole arranged on the gun body for controlling input A compressed air valve to the compressed air of the air nozzle, a compressed air hole passing through the handle of the gun body leading to the piston hole and a pressure measurement and pressure display device arranged in the handle. Background technique [0002] In order to achieve optimum working results in paint spray guns, it is particularly important to adjust the spray pressure in such a way that optimum atomization is obtained at high working speeds and spraying efficiency. Therefore, in order to adjust the pressure accurately and monitor the input pressure, a pressure regulating valve with a pressure gauge is usually provided before the air input port of the spray gun. However, the operation of the spray gun...
