Limitation.
The utility model discloses a kind of solenoid valve, including：Shell 1, spool 2 and electromagnet 3.
Referring to Fig. 2 and Fig. 4, shell 1 has at least three cavitys, has accommodating chamber 14 in the both sides of cavity, it should be noted that
, being not the both sides of each cavity has accommodating chamber 14.In other words, multiple cavities (at least three cavitys) are located at two
Between accommodating chamber 14.There are two the tools of electromagnet 3, is separately positioned in accommodating chamber 14, that is, is located at cavity both sides, has per side
One electromagnet.
There are two interval setting accommodating chambers 14, the electromagnet 3 to be arranged in the accommodating chamber 14 for tool on shell 1 in other words
The interior and described shell 1 also has at least three cavitys, is respectively positioned between described two accommodating chambers 14；
Certainly, the accommodating chamber 14 of both sides is symmetrical arranged, and the electromagnet 3 in accommodating chamber 14 is also symmetrically arranged.
Also there is the first passage 15 for penetrating through each cavity, spool 2 are slidably arranged in shell 1 in first passage 15,
And it is sealed between spool 2 and first passage 15.Spool 2, can be in first passage 15 under the action of 3 electromagnetic force of electromagnet of both sides
Inside slided.The axial length of spool 2 is more than the width of each cavity.Preferably, first passage 15 is located at the cavity
Central part.
It seals, can be realized by oil sealing between above-mentioned spool 2 and first passage 15.
Preferably, referring to Fig. 3, there is spool 2 middle part 21 and end 22, the end 22 to be located at 21 both sides of the middle part,
And the diameter of the end 22 is less than the diameter at the middle part 21, is sealed between middle part 21 and the first passage 15.Accommodating chamber
There is second channel 16, the end 22 is slidably set in the second channel 16 between 14 and the adjacent cavity.
Further, the solenoid valve of the utility model further includes spring 4, is arranged at the both ends of the spool 2, each bullet
One end of spring 4 is connect with the spool 2, and the other end is connect with the shell 1.Certainly, preferred mode is to be set in end
