Abstract

An electromagnetic valve functions effectively via exhaustion of air exhaust path. A main valve shaft 17 is able to reciprocate in an axial direction and formed in a receiving hole 16 formed in a valve casing 20. An air supply port 21 and air exhaust ports 22, 23 are switched by the main valve shaft 17 to connect output ports 22, 23. By electrifying a coil of a solenoid 32, a movable core 36 reciprocates axially, and a pilot valve moving in connection with the movable core 26 switches an air supply passage 39 connecting to the air supply port 21 and an air exhaust passage 42 to connect to an output passage connecting to an air pressure chamber 29. A filter 52 is assembled in the air exhaust passage 42 to prevent dust from drifting into the passage.

In addition, inclusions are prevented from entering the exhaust passage 42 from the outside. Fig. 3 is a sectional view showing a solenoid valve according to another embodiment of the present invention, and the multi-valve base 10 shown in Fig. 1 is omitted. In addition, in FIG. 3, the same components as those shown in FIGS. 1 and 2 are assigned the same reference numerals. / 、 The solenoid valve shown in Fig. 3 is installed on both sides of the main valve part 15 which is the same as that shown in Fig. 5 and is equipped with an electromagnetic coil unit 32 as shown in Fig. 1 Part 19. Therefore, this solenoid valve is provided at both ends of the main valve shaft 17. The two solenoid valve type two-position valve of the piston 27 has the relationship of two control valves in one electric valve and two filters. Located in the exhaust passage 2: In this type of electromagnetic wide, it also prevents miscellaneous logistics. Each exhaust passage 42. Fortunately, the electromagnetic 阙 11 shown in the figure is a two-position valve, such as the main valve with spring force. The shaft is set to the neutral position 罟 ^ ^ ^ η-. When the main valve shaft 17 is moved to a position known by the stroke by each control valve, it can be a three-position valve. Alas, the control formed by the == on-off valve 37 and the tongue valve 44 is switched between the air supply passage 39 and the exhaust passage ^, and the movable iron core 36 makes the output passage valve, which can be itself a single unit. Connected direct-acting solenoid and port solenoid valves are used. In this
