7, 8, 9; a spacer 10; a leaf spring 11, one end of which is fixed to one end of the shaft 5 by the above-mentioned portion of the special nut 32; A cartridge 12 to be formed, a cover 15 including a coil of a differential transformer, a bearing box 17 containing a ball bearing 16 for supporting the other end of the shaft 5, an O-ring 13,
14, the leaf spring 1
The other end of the shaft 1 is fixed in contact with the main body 19 with the mounting bolt 18 so that one end of the shaft 5 is centered. Here, the movable portion 48 of the linear motor 20 is formed by the movable iron core 4, the shaft 5, the leaf spring 11, and the portion of the special nut 32. Hole 4 with bottom leading to
3, an end surface 47, cylindrical portions 44 and 45, a hexagonal column portion 46, and holes 40 and 41 which are perpendicular to each other and pass through the hole 43 in the cylindrical portion 44 through the axis of the movable portion 48. . The spool 21 has a plurality of lands 25, ‥‥ and a plurality of rods 26, に on an outer peripheral portion, and has a through hole 22 therein and a plug 37 for screwing a left end thereof therein. The special nut 3 at the right end of the hole 22
The right end of the rod portion 26 is connected to an enlarged hole 42 larger than the cylindrical portion 44 and has a hole 39 that passes through the enlarged hole 42 that is perpendicular to the center of the axis of the spool 21. The connecting portion 23 includes a connecting member 30 integrated with the spool 21, a connecting member 31 integrated with the movable portion 48 of the linear motor 20, and a spring 3 mounted on the hole 22.
6 and a cap 38 having a window.
Reference numeral 0 denotes a portion of the spool 21 including the plug 37 and a cylindrical pin 33 which is loosely fitted in the hole 39, and the connecting member 31 has a play in a portion other than the portion of the special nut 32 and the hole 41. At the same time, the cylindrical pin 33 passes through the hole 39 of the special nut 32 with a play, and the cap 38 is connected to the cylindrical pin 34 with respect to the cylindrical pin 33. On the other hand, the above-mentioned enlarged holes 42 are each provided with flexibility to prevent them from coming off, and the connecting member 30 and the connecting member 31 penetrate each other in a chain shape and become caught. On the other hand, the spring 36 to be press-fitted is the plug 3 serving as the spring contact inner surface of the connecting member 30.
7 and, on the other hand, the connecting member 3
1 is pressed against the end surface 47, which is the outer peripheral portion of the front end, and as a result, an opposing inner surface portion is formed on the cylindrical pin 33 facing the spring contact inner surface portion of the connecting member 30. The inner surface of the connecting member 31 is formed and pressed against each other to form a point contact, thereby maintaining a working point. The operation of the method for connecting the spool having the above configuration will be described below. When the connecting member 31 is operated to the left by one of the excitations of the linear motor 20, the end surface 47, which is the outer peripheral portion of the distal end of the connecting member 31, contacts the spring contact inner surface of the connecting member 30 via the ball 35 and the spring 36. Is pushed to the left, and the spool 21 of the electromagnetic control valve is operated to the left. At this time, the cylindrical pin 33 which is the opposed inner surface of the connecting member 30 is always held at the inner surface of the connecting member 31 by the spring 36. A cylindrical pin 34
And keep it pressed. When the connecting member 31 is operated to the right by the other excitation of the linear motor 20, the connecting member 31 operates the connecting member 30 to the right together with the spring 36 via the pressure contact portion. Here, the shape of the two inner surface portions in the above-mentioned press contact portion, which is the point of action of the connecting member 30 and the connecting member 31, is a cylindrical surface and is orthogonal to each other, and thus a point contact. The connecting members 30 and 31 are not in contact with the holes 40.
The linear motor can slide slightly perpendicular to each other, tilt slightly relative to each other, and rotate slightly in the twisting direction of each other, so that it does not cause any trouble as an electromagnetic control valve. The movable portion 48 of the unit 20 can freely operate the spool 21 without any backlash or backlash. Further, since the moment force exerted by the spring 36 and the action point can be almost neglected, the spool 21 does not have a twist, and there is no cause for inducing the fluid sticking. Further, the ball 35 may not be provided, the cylindrical pin 34 may be a sphere in contact with the hole 43, and the cylindrical pin 33 may be press-fitted into the hole 39. Further, the function and effect of the present invention are not lost as long as one or both of the connecting members 30 and 31 can be formed into a ring shape and can accommodate the spring 36. In addition, the connecting members 30 and 31 having a hook may be partially opened to form a C-shape or a U-shape. Further, the press contact portion, which is the point of action, can be brought into line contact or surface contact by an appropriate method (not shown). FIG. 2 shows another embodiment in which the spool connecting method of the present invention is applied to the movable portion 48 'of another linear motor 70, and the same members are denoted by the same reference numerals and detailed description thereof will be omitted. In the linear motor 70 of this embodiment, two permanent magnets 71 and 72 are accommodated between the coil 73 and the movable iron core 4, and the movable portion 48 'is constructed and supported in substantially the same manner as in the case of the linear motor 20. Therefore, the position can be controlled autonomously. FIG. 3 shows another embodiment in which the spool connection method of the present invention is applied to another electromagnetic actuator. A torque motor 80 capable of autonomously controlling the position is used as the electromagnetic actuator. In this embodiment,
One end of the connecting rod 81 is fixed to the special nut 32 with the hole of the cap 38 interposed therebetween, and the other end of the connecting rod 81 can be rotated on the swing shaft 85 of the torque motor 80 with slight play and on the paper. As described above, a spring 82 surrounding the connecting rod 81 is press-fitted on a side of the swing shaft 85 via a spring receiver 83 while the connecting rod 81 is connected. Here, the connecting rod 81 becomes an end of the movable portion 48 ″ of the torque motor 80 and is integrated with the connecting member 31.
