The coil surrounds a central pin 13 and a mover 14 extending from the bottom. The pin 13 extends almost to the center of the casing. A conical counter electrode 15 is formed on the end face of the free end of the pin. The counter electrode is separated from the magnetic pole 17 formed corresponding to the counter electrode of the mover 14 with a working gap 16 therebetween. That is, the magnetic pole and the counter electrode have the same cone angle.

The part is depressed. As a result, the mover is firmly connected to the push rod. For swaging, the mover is received together with the push rod in the tool receptacle 28 and a maximum distance X from the lower edge of the tool receptacle to the tip 29 of the push rod in contact with the opposing holder 30 is defined. .

孔がタンク45に接続されている。The tip of the push rod 21 guided in the hole 49 of the pole plate 24 penetrates the hole 35 of the valve seat plate 36, and a valve for a spherical valve body 38 is provided on the surface of the valve seat plate opposite to the armature. A seat 37 is formed. The valve body is present in a chamber 39 of the valve casing, and a second valve seat 40 is formed at the bottom of the chamber 39 of the valve casing. A bag hole 41 is connected to the second valve seat, and a pump connection portion 42 is connected to the bag hole. A consumer connection 44 is also connected to the chamber 39 outside the second valve seat. A chamber 46 is provided between the valve plate 36 and the pole plate 24 in the valve casing.
This chamber is connected to a horizontal hole 47, and the horizontal hole is connected to a tank 45.

It flows through the chamber 46 and the lateral hole 47 to the tank. Pump connection
42 is closed. As is evident from this, the solenoid valve is closed without current. When the coil is excited, the mover 14 is pulled toward the counter electrode 15 against the compression spring 19 and the force. The pressure generated by the pump 43 causes the valve body 38 to abut against the valve seat 37 so that the pressure medium

構造によって理想的な形で満たされる。By forming the magnetic pole 17 and the counter electrode 15 in a conical shape, the surface of the working gap is enlarged. As shown in FIG. 2, the magnetic force / characteristic line K1 is significantly flatter than the magnetic force / characteristic line K2 of the solenoid valve having a flat counter electrode. The distance s is plotted on the abscissa, and the magnetic force F is plotted on the ordinate. Particularly, the high attraction force is satisfied in a state where the gap is large and the adhesion force when attracted is small. The center offset between the mover and the counter electrode in the casing must be small to minimize the generated magnetic lateral forces and to avoid high friction or tilting of the mover. Such requirements are met in an ideal manner by the aforementioned solenoid valves, for example by means of an integral construction of the casing.

することを阻止する。The pole plate 24 has three functions: firstly, the lines of magnetic force are guided via the pole plate and the radial gap 48 between the outer circumference of the mover and the cylindrical recess 23. Recess 23 keeps the radial gap length 1 large, which minimizes gap loss. Furthermore, the spacing between the pole plate and the mover is kept small due to the integral construction of the casing, which keeps the center offset small, which has an advantageous effect on the magnetic losses in the radial gap 48. In addition, a hole 49 in the center of the pole plate serves for guiding the push rod 21. Another important function of the pole plate is to shield the armature chamber against the ingress of ferromagnetic particles, which are present in high proportions in the drive oil, especially when used in drive transmissions. Ferromagnetic particles accumulate in the highest range of field densities, i.e., in the radial and working gaps, which will affect function over time or cause valve failure. Especially when switching the mover,
That is, when the pressure is released from the consumer connection portion 44 toward the tank connection portion (lateral hole 47), the magnetic pole plate causes the pressure medium, and thus the ferromagnetic particles contained in the pressure medium to flow into the mover chamber 26. To block.

が省略される。A further advantage of the solenoid valve according to the invention is that the valve housing is formed from a different material, for example steel or aluminum, based on the flux flow via the pole plate 24. The material of the valve housing can be selected, for example, from the same material as the control housing of the drive train, so that the gap is not changed on temperature fluctuations based on the same thermal expansion, so that the leakage flow is not increased. Due to the special structure of the solenoid valve and the good magnetic force characteristic line,
Means such as an adjusting process, a compensating plate or an adjusting screw are omitted.
