ことを目的とした電磁式膨張弁に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic expansion valve intended to obtain stable valve operating characteristics in an expansion valve or the like that controls flow rate in a refrigeration cycle device.

ある。 The thermoelectric expansion valve conventionally used as a control mechanism for the refrigeration cycle has poor response characteristics and induces changes in the state of the refrigerant due to heat radiation from the thermoelectric part, which causes unstable vibrations in the refrigeration cycle control system. As a result, the refrigeration cycle function may be damaged.

うように流れる。 In the figure, 1 indicates the main body of the device, and the entire body is composed of a body 3 forming a secondary chamber 2 and a body 5 forming a primary chamber 4.
The secondary chamber 2 is partitioned off by a valve seat part 6 and communicated with it by a valve seat opening part 7. Valve body 10
is a valve stopper 12 that opens and closes the passage of the valve seat opening 7;
The valve shaft 13 supports the valve shaft 13, and is supported in balance by springs 14 and 15 at both ends (upper and lower ends) of the valve shaft 13, and is configured to be movable. The valve obturator 12 is configured such that a magnetic fluid 17 is enclosed and sealed with an elastic member, and a part of the valve body facing the valve seat, that is, a region of the valve obturator 12 is surrounded by a rigid member 16. It is structured closely.
The lower end chamber 18 of the valve body 10 is isolated from the primary chamber 4 and communicated with the secondary chamber 2 through a pressure introduction path 19 . An electromagnetic coil 20 is disposed so as to surround a part of the valve body as a magnetic field necessary to induce the flow of the magnetic fluid 17, and is fixed to the body 5. The electromagnetic coil 20 is energized from a terminal 24 and is configured to be airtight from the outside. The fluid flows in from the inlet section 21, passes through the primary chamber, is ejected from the valve seat opening into the secondary chamber 2, and flows toward the outlet section 23.
次に作用と効果について説明する。端子２４よ

強さが変化し、さらに弁閉止子１２内部の磁性流
体１７が吸引され、かつ、それによつて生じる。
流動圧が弾性部材を変形させて、これと一体に動
く剛性部材１６にも変位を起させる。 Next, the action and effect will be explained. When electricity is applied from the terminal 24, the strength of the magnetic field changes depending on the magnitude of the current, and the magnetic fluid 17 inside the valve stopper 12 is attracted and generated thereby.
The fluid pressure deforms the elastic member and causes displacement of the rigid member 16 that moves together with the elastic member.
この場合弁閉止子１２領域を流れる流速は非常
に早いため、弾性部材のみで成形されている場合
であれば、その摩擦力が大きいことにも関連して
流体流れは滑らかに流れず、乱流を起す原因とな

生じる。そこで、弁閉止子の一部に剛性部材でお
うことによつて流れが滑らかになり、簡単でかつ
有効に流量制御特性が向上するものである。 In this case, the flow velocity in the valve stopper 12 region is very fast, so if it is made of only elastic members, the fluid flow will not flow smoothly due to the large frictional force, but will be turbulent. This causes problems with the operational stability of the refrigerant cycle. Therefore, by enclosing a part of the valve stopper with a rigid member, the flow becomes smooth and the flow control characteristics are simply and effectively improved.

ものである。 Furthermore, unlike conventional thermoelectric expansion valves, it has the effect of preventing unstable operation of the refrigeration cycle caused by slow response characteristics and changes in refrigerant state due to heat release from the thermoelectric section. In the case of the present invention, regardless of the flow direction from the inlet to the primary chamber, the valve seat opening, the secondary chamber, and the outlet, changing to the reverse flow will not cause any problems and will be effective. This has the effect of controlling the flow rate.

わめて実用的効果の大なるものである。 The flow rate control device of the present invention includes a valve body made of an elastic member that encloses a magnetic fluid and deforms in response to the flow of the magnetic fluid, and a part of the elastic member of the valve body that faces a valve seat portion. is covered with a rigid member, an electromagnetic coil is provided at a predetermined interval around the valve body, and the gap between the valve seat and the valve body is controlled by controlling the magnetic field by controlling the energization of the electromagnetic coil. A rigid member is provided in the part facing the seat, that is, the part where the flow velocity is fastest and the elastic member is likely to deform.In order to prevent deformation due to fluid pressure, the response characteristics of the valve body are quick and cause a change in the thermal state of the fluid. It is possible to stabilize the operation of the refrigeration cycle and perform smooth flow control, and by covering a part of the valve body with a rigid member, the flow of magnetic fluid inside the valve body becomes smooth and the flow control characteristics are further improved. In addition, since a rigid member is provided on the part that opposes the valve seat, the rigid member can protect the surface from deformation due to the contact of the valve body with the valve seat. This has extremely practical effects, such as preventing the valve body from remaining deformed due to its own elastic force and making accurate flow control impossible.
