Description

The subject of the invention is pneumatically operated, primarily intended to drive the mechanical wrenches of ratchet tin.

Known engines of the same kind, having a reciprocating cylinder and a fixed rod, have an essential drawback, which is that the action of their nose-distributing device is based on the principle of the engine, thus eliminating the possibility of engine operation with a small number of working strokes.

In the described pneumatic engine 1M, this drawback is absent, since it uses a distribution system using the difference in pressure in the cavities, which makes it possible to operate the engine with a very small number of working strokes.

FIG. 1 shows a schematic view of the engine section; in fig. 2 is the same section A-A in FIG. one; ia of FIG. 3-zolotnikova vtu.ka, section bb on fig. one.

The engine consists of a cylinder /, with a reciprocal reciprocating motion, a fixed hollow piston 2 and a hollow rod 5, through the cavity of which air is supplied.

In order to get more effort during the course of the work and even lower at idle and reduce the required flow rate of 150 t. T, the ear to the current 3 is given a stepped shape.

In order to control the movement in 1 in 4 and out of 5 windows of the inlet 3, the primer moves in the annular gap between the rod 3 and the pin 2 of the spool bushing 6, provided with windows 7 and cutouts 8 for the passage of keys 9, which move under the influence of end caps 10 and 11 mobile unit 1.

To ensure stable operation with a very small number of strokes (5-6 per minute), end caps 10 and 13 of the stem, 3, are opened by means of end caps 10 hours // in each stroke what creates the necessary pressure differential between the cavity of the cilice 1 at 11 intermediate positions of the gold sleeve 6.

The hub is fixed in the extreme positions with the engine vertical and positioned by a ball-shaped stop 14 with a flat spring 15 entering the recess of the rod 5.

The position of the engine shown in the chrsts-zhs corresponds to the beginning of the working stroke.

At the same time, the left cavity communicates with the atmosphere through an additional 1 nd outlet pads 13, thereby creating the necessary pressure differential between the cavities to terminate the working stroke. When moving to K: the leftmost position of the spool bushing 6 overlaps the iuiycKHbie window 4 and fully opens the main release of the 1st okpa 5 of the second band 11, etc. Under the effect of the pressure on the right side of the 10, idling occurs of which otkrpiiiots to 11 (X1ite. t: -1Ye vy1 tknye okpa J2.
