本発明は、接極子に結合される弁体が弁ケース内に案内
され、接極子が圧力媒体を満たされた接極子空間内を動
く、電磁弁特に圧力調節弁に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a valve body coupled to an armature is guided in a valve case, and the armature moves in an armature space filled with a pressure medium. It relates to solenoid valves, especially pressure regulating valves.

作動開始後、不充分な油充填のため依然として振動の生
ずる可能外がある。In such known valves, in which the armature moves in a pond to damp continuous vibrations, ferromagnetic particles contained in the oil chamber can be deposited at the points of the strongest magnetic field, ie at the magnetic poles. Attempts have therefore been made to prevent a constant flushing of the armature space caused by residual pressure in the lower region of the valve by trampling the armature space, for example with an O-ring. However, this results in a significant increase in the filling time, since the armature space is emptied after a certain stoppage time and oil has to be pumped into the pressure space through the gap of the plunger or support. Therefore, after the start of operation, vibrations may still occur due to insufficient oil filling.
本発明の課卵は、これらの欠点のない電磁弁を提供する
ことである。The object of the invention is to provide a solenoid valve that does not have these drawbacks.
この課題を解決するため本発明によれば、接極子空間か

られている。In order to solve this problem, according to the invention, a hole is led outwards from the armature space and likewise at least intermittently into a space accommodating the pressure medium, in which a two-way check valve is provided. .
このような電磁弁は、接極子空間が例えば長い停止時間
後再び充填されるまでの間しか、接極子空間の洗い流し

の危険は著しく減少する。Such a solenoid valve has the advantage that the armature space can only be flushed out until it is refilled, for example after a long downtime. The risk of contamination is thus significantly reduced.

You are guided inside. Inside the case IO, radially outside the right support 31, there is a coil 32 of an electromagnet. In the part of the case 10 remote from the lid 11 there is a member 33 in which an inlet hole 34 is formed which extends coaxially with the valve body 18 . A valve seat 23 is located at one end of this inflow hole. Immediately following the valve seat 23 there is an annular space 36 in the member 33, which is penetrated by a transverse through hole 37. Inside the annular space 36 is the end of the valve body 18 .

情によってはこの接極子空間を空にすることができる。An annular groove 39 is formed in the left part of the case IO, from which a stepped hole 40 leads to the left part of the armature space 15A. Smaller stride 40A to larger stride 40A
The transition to B is above the stepped bore 40 forming a valve seat 41 for a spherical valve body 42 which is supported with sufficient axial and radial play within the stepped bore 40. Part 40B
A sleeve 43 is fixedly screwed into the valve seat 41.
Similarly, the end face nearer to the valve seat 44 for the valve body 42 is formed. This valve body 42 is hollow or consists of a material that is lighter than the pressure medium contained in the armature space. If this armature space is not yet filled with pressure medium, the valve body 42 rests on the valve seat 41. The air forced by the pressure medium can flow past the valve body and reach the outside via the stepped hole 40. When the pressure medium level gradually reaches the level of the valve body 42, this valve body leaves the valve seat 41 and is pushed by buoyancy onto the valve seat 44. Flushing of the armature space is therefore substantially interrupted by such a sealing based on the float principle. When the pressure in the annular space 36 decreases, the armature space 15A is largely prevented from emptying, since the valve body 42 now rests on the valve seat 41 when the pressure medium level decreases. Thereby, the flow of pressure medium through the magnetic poles is kept very clear and the armature space remains filled with pressure medium for most of the time. Only after a long break time can this armature space be emptied under certain circumstances.
電磁石が励Ｎされていると、弁体１８はその開放位置に
あり、仕方媒体は流入穴３４から流出穴３７即ち負荷へ
流れる。When the electromagnet is energized, the valve body 18 is in its open position and the medium flows from the inlet hole 34 to the outlet hole 37, ie to the load.
