Entrance sleeve 3 enters, and flows out along the left groove 612 of sliding block 6 from first outlet adapter tube 4.
In the present embodiment, when sliding block 6 rises to extreme position, the first sealing 61 is by 412 envelope of the first recirculation hole
Stifled, when sliding block 6 drops to extreme position, the second envelope portion 62 blocks the second recirculation hole 422, therefore, positioned at 6 two sides of sliding block
The distance of first sealing 61 and the second sealing 62 on longitudinal cross-section, as movement of the sliding block 6 in whole work process
Stroke.
In order to guarantee the validity of the closure of sliding block 6, there are same apertures in the first recirculation hole 412 and the second recirculation hole 422
In the case where, only need to the movement travel of sliding block 6 be equal to or is slightly less than the first recirculation hole 412 or the second circulation 422
Diameter.When the movement travel of sliding block 6 is slightly less than the diameter of the first recirculation hole 412 or the second recirculation hole 422, although when first
When sealing 62 blocks the second recirculation hole 422, the first sealing 61 can block a part of first recirculation hole 412 simultaneously, however,
Due to the presence of groove 612, fluid still can be flowed out along groove 612 from first outlet adapter tube 4.
And in the case that the first recirculation hole 412 is different with the aperture of the second recirculation hole 422, then it need to only guarantee sliding block 6
Movement travel is equal to or slightly less than biggish circulation bore dia in two recirculation holes.The diameter of even the first recirculation hole 412 is greater than
The movement travel of sliding block 6 is then equal to or is slightly less than the diameter of the first recirculation hole 412 by the diameter of the second recirculation hole 422；
Conversely, setting the movement travel of sliding block 6 to if the diameter of the second recirculation hole 422 is greater than the diameter of the first recirculation hole 412
In or be slightly less than the diameter of the second recirculation hole 422.
It should be noted that " being slightly less than " of the present invention, which refers to, can make suitable subtract to the movement travel of sliding block
It is small, it will be understood by those skilled in the art that above-mentioned can be in right amount because of the mistake within the allowed band caused by being machined
Difference is also possible to the setting made intentionally to be further reduced electromagnetic force.
It in actual processing, can according to need, design the first sealing 61 and the second sealing 62 in the longitudinal direction
Then the distance being staggered is formed by modes such as injection moldings.Obviously, this structure in terms of existing technologies, sliding block 6
Movement travel can greatly reduce, since core iron 24 is moved simultaneously with sliding block 6, the stroke of core iron also accordingly subtracts
It is small, in this way, the electromagnetic force that driving core iron 24 moves also can reduce, therefore can be can be realized as using low power coil.
