間隙調整機構を調整して上記間隙を所定の間隙に高精度
に調整することが行なわれている。Generally, when a brake booster is activated, the brake reaction force applied to the output shaft is transmitted from the output shaft to the input shaft via a reaction disk and a valve plunger that constitutes a valve mechanism. In this type of reaction force transmission mechanism, it is necessary to form a predetermined gap between the reaction disk and the valve plunger in order to determine the timing for starting reaction force transmission at the initial stage of operation of the brake booster. If the gap needs to be within a predetermined range with high precision, a gap adjustment mechanism that can adjust the gap between the two is provided, and this gap adjustment mechanism is adjusted to adjust the gap to the predetermined gap with high precision. is being carried out.

を行なうことができるようにしたものである。In view of these circumstances, the present invention urges the reaction disk with a predetermined pressing force, elastically deforms it in advance to bulge toward the valve plunger side, and also deforms the end face of the bulged reaction disk. As a reference, the gap is adjusted by the gap adjustment mechanism so that, for example, the tip end face of the valve plunger comes into contact with the end face of the gap adjustment mechanism, and by such adjustment, the predetermined compression is applied to the reaction disk. When a force is applied, the reaction disc and valve plunger always come into contact and transmit the reaction force, so even if there is variation in the amount of elastic deformation for each reaction disc, the gap can always be adjusted optimally. It is designed so that it can be carried out.

ている。FIG. 2 is a partial cross-sectional system diagram illustrating a method for adjusting the gap, in which the valve body 6 is fixed to a base 35, and the input shaft 21 and output shaft 23 have separate shafts 21 and 23, respectively. Pressurizing devices 36 and 37 that apply pressing force are interlocked. Then, the opening on the constant pressure chamber 4 side of the passage 14 formed in the valve body 6 is closed by a closing member 38, and one end of a conduit 39 is connected to this closing member 38, and the other end of this conduit is connected to an on-off valve 40.

We can assemble all the parts necessary for valve body 6. Next, with the on-off valve 40 opened to introduce negative pressure into the passage 14, the input shaft 21 is gradually advanced by the pressurizing device 36, and the fluid circuit by the valve mechanism 7 is switched. When the fluid circuit is switched by this valve mechanism 7 and atmospheric air is introduced into the passage 14 communicating with the constant pressure chamber 4 via the filter 1B, the pressure inside the passage 14 fluctuates. The pressure device 36 detects the pressure fluctuation by the detector 41, immediately stops the forward movement of the input shaft 21 +f-, and holds it at that position.

止する。At this time, the reaction disk 22 is elastically deformed under the biasing force of the output shaft 23, and its right end surface is connected to the valve plunger 11.
I11 is extended to the side, and the output shaft 23 comes into contact with the left end surface of the valve plunger 11 before being biased with a predetermined pressing force. When the reaction disk 22 comes into contact with the valve plunger 11, the member 26 constituting the valve plunger 11 pushes out the adhesive 30 from inside the four parts 27 against the member 25 fixed by the input shaft 21.
Due to the elastic deformation of the action disk 22, the second
Move to the right in the diagram. Then, when the urging force of the output shaft 23 becomes a predetermined pressing force and the reaction disk 22 stops expanding due to elastic deformation, the member 26 also stops moving to the right.

Once removed, the gap adjustment work will be completed.

。As can be understood from the above description, the gap between the valve plunger 11 and the reaction disk 22 is formed when the pressing force by the other pressing device 37 is released while the pressing force by the pressing device 36 is maintained. Since δ corresponds to the gap that can transmit the reaction force to the input shaft 21 at the moment when the brake reaction force applied to the output shaft 23 reaches the above-mentioned predetermined pressing force, δ corresponds to the gap that allows the reaction force to be transmitted to the input shaft 21. Even if there are variations in the amount of deformation, etc., it is possible to reliably adjust the waiting period for starting transmission of the reaction force to a predetermined time.

Furthermore, especially when using a liquid adhesive with low viscosity, the above-mentioned adjustment work may be performed with the valve body 6 facing vertically, that is, with the adhesive not flowing out from inside the four parts 27. good. Furthermore, in the embodiment described above, it is detected that the valve body 13 and valve seat 12 of the valve mechanism 7 open due to pressure fluctuations in the negative pressure, but it is also possible to use positive pressure instead of negative pressure. Of course.

The left end surface of the valve body 6 may have a step or a spherical surface for slightly displacing the valve seat 12 of the valve plunger 11 and the valve seat 10 of the valve body 6 in the axial direction, if necessary.

ばより高精度の調整を行なうことが可能となる。Furthermore, the gap adjustment mechanism 24 is not limited to the one described in the embodiment described above, and any conventionally known appropriate mechanism can be applied. For example, a gap adjustment mechanism can be used in which the two members 25 and 260 are screwed together and the gap δ is adjusted by changing the screwing position. In that case, a predetermined pressing force is applied to the output shaft 23 in advance. In addition, by changing the screwing position in this state, fluctuations in the pressing force acting on the output shaft 23 can be detected, and from this fluctuation it is possible to detect whether the valve plunger 11 and the reaction disk 22 are in contact. Although it depends on the configuration of the gap adjustment mechanism, it is not always necessary to bring the valve plunger 11 and the reaction disk 22 into contact with each other, and the adjustment may be completed when the valve plunger 11 and the reaction disk 22 are just about to come into contact. Even in this case, it is possible to perform adjustment with higher precision than in the past.
