Description

./

The invention relates to a manual tool for adjusting the valves of an internal combustion engine.

The purpose of the invention is to enhance ease of operation by providing communication between the keys.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG.

The fixture contains two nut spanners V and 2, each of which has, respectively, a head 3 and 4 with a gap 5 and 6, as well as a handle 7 and 8. On the head 3 there is an open shoulder 9, and on the head 4 - bead 10. Both beads are of equal height and coaxially arranged. The key 1 has a dial 11 with a scale of 12 and a groove 13 in which the viewfinder 14 is mounted so that it can be moved. In the axial rotation of the latter, there is a spring-loaded handle 8 of the key 2 ,. On the handle 1 there is an axial groove 15 in which a magnetic plate 16 is installed, in which a key 2 borrows from the end face of the collar 10, which has the possibility of axial movement relative to the reticle 14. Limb 11 is hinged on the key 1 using

axes 17.

The device works as follows

in a way.

Holding the device by the handle 7. pulling the key 8 back to the handle 8. The end face of the shoulder 10 slides along the magnetic plate 16, which provides the connection between the heads 3 and 4 in the vertical direction. Having installed the key 1 with the shed 5 on the lock nut (not shown), loosen it, and then, releasing the handle B, return the key 2 to the initial position and install its shed 6 on the adjusting head

bolt (not shown) and unscrew it before contact with the brisk rocker arm of the gas distribution mechanism (not shown). In this case, the key 1 holds the lock nut.

The process of unscrewing the adjusting bolt is carried out in such a way that after turning the key 2 at a certain angle, it is moved by the handle 8 in the direction of the sighting 14, the shed 6 is removed from contact with the edges of the adjusting bolt, then it is turned to its original position and the shed is set again 6 on the head of the adjusting bolt. When the key 2 is axially displaced, the end of the collar 10 slides along the magnetic plate 16, attracting it, excluding the accidental movement of the head 6 vertically.

Then the zero division of the scale 12 leads to the risk of the reticle 14 and, holding the lock nut with key 1, the key 2 tightening the adjusting bolt until the risk of the crosshead 14 coincides with the division showing the necessary clearance. .After this, lock the locknut with the key.
