Abstract

PURPOSE:To enable selecting the direction in one way or another of a moving member and controlling the dimension of the movement by moving the member due to the difference of the polarity of a current applied to a coil and making the dimension of the movement proportional to the value of the current applied to the coil. CONSTITUTION:If a current is applied through a course from a terminal 24a passing coils 22, 23 to a terminal 24b, a magnetic flux as shown by an arrow is generated and a moving member 26 is moved to the right direction. In other words, a pole piece 32 repulses a magnetic pole 19 and attracts a magnetic pole 17. On the other hand, a pole piece 31 repulses a magnetic pole 21 and attracts a magnetic pole 20. Consequently, the moving member 26 is moved to the right direction. This moves a spool 4 to the right direction by a connecting rod 37 and connects a port 5 with a port 7 and a port 6 with a port 8 respectively. When the current is cut off, the moving member 26 returns to the neutral position by the force of a spring 36 and the spool 4 is also returned to the neutral position. On the other hand, if the current is applied in reverse polarity, the moving member 26 is moved to the left direction in the same way and the spool 4 is also moved to the left direction by the connecting rod 37. This connects the port 5 with the port 8 and the port 6 with the port 7.

正しく対応（また１１ｆ４となる。To explain this current flow in detail, first, as shown in (A) in FIG.
From gL source 52 to transistor l8d1 coil O, B,
A current flows through the entire transferer 48C1 resistor 5cIa (see Figure S (b) h) in the path that returns to the power supply 52. Next, when the signal e becomes H level as shown in e→, the transistors 48a and 48'b become conductive, so the coils n and
6 i, the current tries to flow in the opposite direction to 1. 17
Since the coil ρ, 7.3 generates a back electromotive force, the resulting current (current in the direction of the arrow g) flows from the power supply 52 through the transistor 48a'1 to the coil B (in the direction of the arrow A current in the opposite direction to g) is passed from coil 4 to quasiode 49a, ? (52, resistor 50b, Gr-ord 49b) It flows in a path that curves to coil B. Therefore, it is difficult to flow to 1)b."El: i'
Ac becomes a negative value as shown by (-). Immediately, a current flows in the direction opposite to the arrow. The current due to this back electromotive force decreases with the passage of time as shown in Figure 1. When the signal f becomes H level again, a current flows in the path passing through the transistors 48c and 48d'1.This current increases with time as shown in (G).Such an operation is repeated,
Eventually, when the time that the signal e is at the H level becomes longer than the time that the signal f is at the H level, the current from the power supply 52 will flow through the transistors 48a and 48b6 to the coil/l/JZ3. The time becomes longer, and a current flows in the direction opposite to the arrow g in the coils n and 23 (the current in the direction of the arrow g has a negative value as shown in (g)). The current flowing as described above is detected by the circuit 51 and a current signal j is output. The signal is passed to the error amplifier 4
2, and the signal is then subjected to a known correction in a proportional solenoid circuit.As a result,
The current (average current) flowing through Koi/L'JF correctly corresponds to the control signal (also becomes 11f4).

。As mentioned above, when a current g of 6L is applied to the coil/l/'J 23, the electromagnetic force applied to the movable body by the average current value g' and the return force applied to the movable body by the barb 35 or 30 are affected. MJ Yuka moves until it fits. For example, if the above average current value is 0.2A, the force will be balanced at point p in Figure 3, so the movable body will move from the neutral position to the left -0.2 IIIm point in Figure 1. do. As a result, the swab/lz 4 is also moved by the same dimension, and the space between the boats 5 and 8 and between the Horotro and the boat 7 is opened by a value of 7 corresponding to the above-mentioned movement dimension.

る。If the above-mentioned average current value g' changes from this state, (1) the magnetic force also changes accordingly, so the position where the ever-changing electromagnetic force and the repelling force of the driving body are balanced. 3 along the dashed line of the splash characteristic in FIG. In this case, the referee moves to accurately follow the change in the current value g'. This is because the value of the current g flowing through the coil is constantly increasing and decreasing as shown by C and (g) in Figure S, so the moving object I is at a position determined by the above average current value g'. There is a constant slight vibration in Zenchu/B. Therefore, when the above-mentioned current iri g' changes and the movable body I and spool 4 move, are they? It can move without being caught by frictional force against the supporting member, and can move by 10 degrees while following changes in the current value g'.
