Aerofluxuss (outgas) are allowed during pressure.OPR60 " splitting " (opening) is to discharge the pressure of surplus, but biased under a predetermined
Close.Also there is roll-over valve (ROV) 50 to prevent liquid fuel 22 with other in the case that fuel tank 20 is tumbled or in liquid
Mode enters tank 25 in the case of being accumulated in vapor fueled pipeline 21.During running well, such as when vehicle upright and
When liquid not yet enters ROV50, ROV50 is in the pressure allowing between fuel tank 20 and tank 25 and gives tacit consent to open position in a balanced way.
There is the under-voltage or over-pressed shape that the vapor stream do not passed through through ROV50 is otherwise remedied in MUA40 and OPR60 in fuel tank 20
It is biased into closed position during state respectively and open.MUA40 and OPR60 is designed to prevent liquid fuel from leaving through valve module 23
Unless the sealing member set point more than OPR60.
Tank 25 can be connected further using multiple substitute modes.As shown in Figure 2 B, tank can be with the air that can be air
Supply source 29 connects.Tank also can be connected with discharge duct to filter engine exhaust.Due to filtering any overpressure vent gas pair
Environment is beneficial, so tank is connected with valve module 23.Liquid fuel catcher is used for preventing liquid fuel pollution tank 25.In order to
Additional discharge steam consumption, MUA40 also can be connected with tank 25, as shown in Figure 2 C.

Fuel tank 20 is in fluid communication.Port 34 also can be connected via suitable pipeline and is connected with tank 2.To be fired via port 34 using gravity
It is beneficial that material 22 is expelled back into fuel tank 20.But, when valve module is mounted externally, port 34 is connected with fuel tank 20 to draw
Pilot material 22 returns to fuel tank 20.Port 30 and 34 for example pass through they are integrally molded in case half, by fasten,
Press-fit or welding and using or do not use one or more O-ring to be connected with valve module.OPR60 is using movably son
Structure 70 is ground integrated with MUA50 physics.MUA40 is located in OPR60 and is activated by ball 41.Upper spring 61 is against upper shell 31
Biased with moveable minor structure 70.First groove 311 around upper spring 61 and guides it.Float sleeve 32 is included for fixed
Position and the intermediate groove 325 guiding moveable minor structure 70.Moveable minor structure 70 is illustrated as to be had for ball 41
The internal path 71 of sliding cylinder.Internally path 71 includes tapering with detent ball 41 and against steam to seat 72

If exceeding first predetermined value from fuel tank 20 via the steam pressure of port 34, pressure exceedes spring 61
Spring force and moveable minor structure 70 rises, thus makes the lower inserts 73 of minor structure 70 dash forward with the upper ridge of float sleeve 32
Vapor fueled pipeline 21 between 322 is ventilated.This provides overpressure vent to prevent fuel tank swollen in such as hyperpyrexia fuel vapo(u)r
Rupture during the state that swollen or fuel tank collides.Different with existing design, no matter whether ROV50 activated, all provide overvoltage
Release, this is because the passage 324 that ROV seal member 54 is not positioned against leading to OPR the and OVR valve of one seals.Therefore, with overvoltage
Provide upset protection with crossing vacuum relief simultaneously.If user makes their vehicle in the way of the sealing triggering ROV50
Tilt, then user continues to benefit from OVR and OPR protection.Although the fuel tank that such as topples collision or overheated in the case of
A small amount of fuel is possibly off OPR60, but the instantaneous pressure through OPR60 may release and prevent and will occur with fuel tank rupture
Much bigger fuel leakage.Allow liquid fuel from the position of OPR60 and MUA40 of the one parallel to passage 317 for the ROV50
Return fuel tank 20 when OVR float 52 moves away passage 317 under gravity.Therefore, it can omit or use tank 25
Liquid header and valve module 23 between so that during overpressure vent any liquid of release can be expelled back into fuel tank 20 and
Do not pollute tank 25 and do not need to adjust the set point of MUA40 or OPR60.
When for example, mending when producing vacuum because fuel for combustion is extracted or due to fuel tank cooling in fuel tank 20
Activate to valve ball 41.That is, the ball 41 in removable Structure of mover 70 move away taper roller seat 72 so that auxiliary air or
Other gases come fuel tank 20.Replace spherical form, ball 41 can be replaced by disk or plate.In the present embodiment, feed
Air is sucked into fuel tank 20 through port 30 from tank.Different with existing design, no matter whether MUA40 ROV50 starts
All start.That is, when lifting liquid float 521 and rise seal member 54 with passage 317 thus starting and closing ROV50
When, auxiliary air still can enter tank through passage 324.Therefore, valve module 23 prevents fuel tank from making inclination of vehicle in such as user
To collapse in the state of when parking or maintenance vehicle.Due to MUA40 exist liquid or vapor fueled in the case of biased pass
Close, so not having liquid fuel to leave through MUA40 under the state that tilts or tips over.Ensure that one-way flow, because only second
Vacuum state below scheduled pressure value opens MUA40 to flow in fuel tank.
