Under the action of contacted with the lower case.
Further, described device further include: the pin for being flexibly connected one end of the upper housing and the valve.
Further, when the solenoid valve is powered, the first oil circuit cutting, with entrance first oil circuit
Oil liquid increases, and the oil pressure in first oil circuit increases, and under the action of the oil pressure, the piston is transported towards the valve
Dynamic, until the mandril of the piston withstands the valve, oily page can not push the valve, valve cutting second oil open
Road.
The technical effect of the utility model is:
1, used turnover plate type valve structure meets runner and turns few demand, its runner compared with transmission control valve
Turning less, fluid circulation it is more smooth, greatly reduce flow resistance.
2, it is controlled using guide type electromagnetic valve, valve cutting closing reliability is higher, alleviates product weight, reduces
Product contour dimension.

Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples:
Such as Fig. 1, under normal circumstances, oil liquid is passed through product from product import, and little moveable door component 22, which is in, under the state opens
State, oil liquid are flowed to from the channel a-b-c-d-e-f that import is formed through lower case 1 and upper housing 5 and are exported, 8 inner cavity of diaphragm unit
Effect of the oil liquid of (Q chamber) to the not formed power of valve assembly 26, valve assembly 26 are directly opened under the action of oil liquid pressure, oil
Liquid is flowed to through A-B and is exported.
It when the oil liquid for being back to fuel tank need to be cut off, is powered to product, little moveable door component 22 acts on lower gram in electromagnet 20
23 elastic force of spring is taken, close to the valve base 5-1 (RED sector in figure) of upper housing 5, until little moveable door component 22 and valve base 5-1
Contact so that little moveable door component 22 cut off the channel a-b-c-d-e-f, due to channel be cut off, oil liquid be gathered in diaphragm unit 8 with
The inner cavity (Q chamber) that upper housing 5 is formed, Q cavity pressure constantly rises and directly acts on diaphragm unit 8, make diaphragm unit 8 along
Purple arrow direction is mobile in figure, since diaphragm unit 8 and valve assembly 26 are always that (contact position is shown in figure in clamped condition
Shown in middle arrow), the movement of diaphragm unit 8 forces valve assembly 26 to move along red arrow direction in figure, finally to live
Door component 26 contacts (contact position is as shown in arrow in figure) with lower case 1, has cut off the access between A-B, cuts off from import
Flow to the oil liquid of outlet.
Connection relationship between the device assembly, part are as follows:
Valve assembly 26 is fixed in lower case 1, is complemented one another with lower case 1.Diaphragm unit 8 be installed on lower case 1 with
Between upper housing 5, complement one another to form pressure-sensitive chamber with upper housing 5.Mandril in diaphragm unit 8 is contacted with valve assembly 26, film
The compression of piece component 8 is moved after moving by mandril promotion valve assembly 26, and valve assembly 26 and lower casing are finally made
Body 1 contacts.Little moveable door component 22 and the valve base 5-1 of upper housing 5 complement one another, and little moveable door component 22 is supported by spring 23, with
Armature contact in electromagnet 20, after energization, the armature in electromagnet 20 is moved along green arrow direction, pushes little moveable door group
22 compressed spring of part is simultaneously contacted with the valve base 5-1 of upper housing 5.
