る。 、：。DETAILED DESCRIPTION OF THE INVENTION The first invention relates to a variable orifice device used in fluid pressure equipment, and more particularly to a variable orifice device that is operated by an electric signal to change a minute orifice area almost steplessly. , :.

することが好ましい。In recent years, in the technical field of hydraulic power steering systems for automobiles, a variable A11 steering system has been developed in view of the fact that the steering wheel becomes too light when driving at high speeds, resulting in poor driving stability with systems that have constant operating characteristics. Technology is being developed to improve driving stability during high-speed driving by changing the characteristics of the vehicle according to vehicle speed. There are various methods for changing the operating characteristics, and among these methods, there is one in which the orifice area of the variable orifice device must be changed minutely and almost steplessly. It is also preferred that the variable orifice device is actuated by an electrical signal.

ない欠点がある。Once again. An example of an artificial device that can steplessly change the area of a minute orifice when operated by the Electric Hayabusa is the Japanese Patent Laid-Open No. 49
There is one example shown in Japanese Patent No. 33313. In this conventional device, an axial groove that gradually increases in width is formed on the outer periphery of the spool that is fitted into the inner hole of the valve body, while the above-mentioned axial groove is made public in the valve body. A pair of axially spaced bows in the valve steel)? In addition to regulating the rotation of the valve spool, a screw shaft is provided which is threadedly engaged with the valve steel, and this screw shaft is rotated by a DC motor via a reduction gear mechanism. However, in order to displace the valve spool to a position where the desired orifice area is achieved, a configuration is required to detect the position of the valve spool and feed it back to the DC motor control section, and the rotation of the threaded rod and valve spool must be restricted. Since this is necessary, there is a drawback that the configuration is complicated. Furthermore, it is difficult to control the position of the Hults spool with high precision due to looseness in the threaded engagement part between the draw rod and the valve spool and in the rotation regulating part of the valve spool.
Therefore, there is a drawback that the micro orifice area cannot be controlled with high precision.

し、バルブロータリをステンビングモータにより歯車減
速機構を介して回転させるようにしたものである。The present invention attempts to solve the previous drawbacks by modifying the motor and the variable orifice component. A circumferential groove is formed that increases in depth as it goes toward the valve body, and a first port that freely communicates with one end of the circumferential groove is formed in the valve body. The valve rotary is rotated by a stevening motor via a gear reduction mechanism.

置を高精度で制御でき、従って微小なオリフィス面積を
高精度で制御できる。In such a configuration, since the valve rotary is rotated by the stepping motor, a configuration in which the rotational position of the valve rotary is fed back to the stepping motor control section is difficult, and there is also a problem in that the valve rotary is rotated by the stepping motor. Since only a reduction gear mechanism is involved, the configuration is simple, and there is little play between the Stetsbinder motor and the valve rotary, so the position of the valve rotary can be controlled with high precision, and the orifice area can be minimized. Can be controlled with high precision.

In FIG. 1, a valve rotary 3 rotatably fitted into an inner hole 2 of an i-vib body 1 has a connecting protrusion 1a that projects outside the valve body 1. This protrusion 1a has one or two planes formed on its outer periphery to have a half-moon or oval cross section, and the output large gear 5 is rotatably supported by the case 4.
It engages with a hole or groove 6 (having a plane corresponding to the plane of the protrusion 1a) of the shaft part 5a. The intermediate small gear 7 that meshes with the output large gear 5 is connected to the case 4 and the motor support plate 8 fixed to the case 4.
It is rotatably supported. The intermediate large gear 9 provided on the intermediate small gear 7 so as to rotate one bit is the output shaft 10a of the step-hinder motor 10 fixed to the motor support plate 8.
