SU1207749A1 - Pneumatic tool - Google Patents

Description

The invention relates to percussion instruments and can be used in pneumatic tools that work with negative temperature tours.

The purpose of the invention is to increase productivity at negative temperatures by ensuring continuous heating of the handle,

Fig. 1 shows a pneumatic tool, a general view with a notch; FIG. 2 is a section A-A in FIG. 1,

The pneumatic tool comprises a cylindrical body 1 with a handle 2 rigidly connected with it and a channel 3 for supplying the working fluid, a handle 4 which encompasses the handle 2 with a blind longitudinal hole 5 expanding at the inlet in the tangential direction and connected to the channel 3 of the working fluid supply installed at the entrance, aperture aperture 6 with a hole

7, a cross 8, placed in a blind hole 5 and intended for the turbulization of the working fluid,

Pneumatic works as follows

in a way.

When the working fluid is supplied to the pneumatic tool, a small amount of it from the opening 3 enters through the expanding part 9 into the opening 5, forming an intense circular flow, which then flows through the opening 7 of the diaphragm 6 into the atmosphere. As a result, the walls of the bracket 4 are heated providing the required temperature

handles 2,

The flow rate of the working fluid through the expanding, part 9 of the hole 5 is less than 10% of the flow rate of the working fluid for the pneumatic tool. In the summertime, when there is no need to heat the handle 2, the opening 7 of the diaphragms, rags 6 is closed with a plug.

Claims (1)

(-54) A PNEUMATIC TOOL, comprising a cylindrical body with a rigidly connected handle and a channel for supplying a working fluid, characterized in that, in order to increase productivity at low temperatures, it is equipped with a bracket covering the handle with a blind longitudinal hole expanding at the entrance in the tangential direction and associated with the feed channel of the working fluid installed at the inlet of the blind hole with a diaphragm with a hole and a cross, placed in the blind hole and intended for turbulization on the body. _Q
