【発明の詳細な説明】
本発明は、冷凍サイクル装置における流量制御を行う膨
張弁等において安定な弁動作特性を得ることを目的とし
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.
従来、冷凍サイクルの制御機構として用いられている熱
電膨張弁は、応答特性が悪く、かっ熱電部からの放熱に

系における不安定振動が発生しこの結果冷凍サイクル機
能をそこなう恐れがある。The thermoelectric expansion valve conventionally used as a control mechanism for the refrigeration cycle has poor response characteristics and induces a change in the state of the refrigerant due to heat dissipation from the thermoelectric part, resulting in unstable vibrations in the refrigeration cycle control system. As a result, the refrigeration cycle function may be impaired.
本発明は、か＼る問題を解決する目的として膨張弁機能
を有する流量制御装置を提供するもので、以下、本発明
の作用と効果について、図面に沿って説明する。The present invention provides a flow control device having an expansion valve function in order to solve the above problem.The operation and effects of the present invention will be explained below with reference to the drawings.

着して構成している。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 washing chamber 4. , are partitioned by a valve seat portion 6 and communicated by a valve seat opening portion 7. The valve body 10 includes a valve stopper 12 that opens and closes a passage in the valve seat opening 7, a valve shaft 13 that supports this, and is balanced and supported by springs 14 and 15 at both ends (upper and lower ends) of the valve shaft 13. It is configured to be movable. The valve shutoff element 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 shutoff element 12 is surrounded by a rigid member 16. It is structured closely.

に流れる。The lower end chamber 18 of the valve body 1o is isolated from the lower end 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
It is fixed to the body 5. The electromagnetic coil 2o 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 valve, is ejected from the valve seat opening into the secondary chamber 2, and flows toward the outlet section 23.

ると、その電流の大きさに応じて磁場の強さが変化し、
さらに弁閉止子１２内部の磁性流体１７が吸引され、か
つ、それによって生じる。Next, we will explain the action and effect.When electricity is applied from the 0 terminal 24, the strength of the magnetic field changes depending on the magnitude of the current.
Furthermore, the magnetic fluid 17 inside the valve closure 12 is attracted and generated thereby.
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。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

剛性部材でおうことによっ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, there is no problem even if the flow direction is changed from the inlet to the primary chamber, the valve seat opening, the secondary chamber, and the outlet, and the flow is reversed. However, it has the effect of effectively controlling the flow rate.

と向上するきわめて実用的効果の犬なるものである。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. The response characteristics of the valve body are quick and do not change the thermal state of the fluid, making it possible to stabilize the operation of refrigeration cycles, etc., and perform smooth flow control.Furthermore, by covering a part of the valve body with a rigid member, the valve body This has extremely practical effects, as the flow of magnetic fluid within the body becomes smoother and flow control characteristics are further improved.
