After vehicle opens merit, hydraulic power supply operates, from fuel tank oil suction, by the oil-out P mouth of hydraulic power supply to system fuel feeding, hydraulic oil flows simultaneously into hand-operated direction valve P mouth and overflow valve P mouth (because overflow valve now main valve plug cuts off), and hydraulic oil can only enter hand-operated direction valve P mouth；
If do not operated hand-operated direction valve (spool returns to middle position), hydraulic oil is returned directly to fuel tank from hand-operated direction valve T mouth；
When hand-operated direction valve pushes second to, hand-operated direction valve P mouth is connected with A mouth, B mouth is connected with T mouth, hydraulic oil simultaneously enters hydraulic control one-way valve V mouth and the first sequence valve V mouth, now the first sequence valve V mouth cannot connect (being dissengaged positions because having check valve and main valve plug from V mouth to C mouth direction in sequence valve) with C mouth, and hydraulic oil can only pass through hydraulic control one-way valve, flows out from hydraulic control one-way valve C mouth, enter locking cylinder cavity of resorption, promote piston action；The hydraulic oil of locking cylinder epicoele flows out simultaneously, flow into hydraulic control one-way valve Pil mouth and the second sequence valve C mouth (because hydraulic control one-way valve Pil mouth is without oil-out), so hydraulic oil can only flow into sequence valve through the second sequence valve C mouth, flow out from V mouth through sequence valve internal one-way valve, entering hand-operated direction valve B mouth, now hand-operated direction valve B mouth connects with T mouth, and hydraulic oil outflows back to fuel tank from T mouth, (now locking cylinder piston rod promotes latch hook action by connecting fork and connecting rod, it is achieved back door unlocking motion)；When locking cylinder piston shifts extreme position onto, hydraulic fluid pressure in locking cylinder cavity of resorption to this section of loop of oil pump P mouth gradually rises, when this force value reaches the force value that the first sequence valve is arranged, internal main valve plug will be promoted to open by the pressure feedback mouth in the first sequence valve, so that the V mouth of the first sequence valve connects with C mouth, now hydraulic oil flows out from the first sequence valve C mouth, enter enabling oil cylinder cavity of resorption, flow out with the hydraulic oil of enabling cylinder upper cavity oil, flow into the second sequence valve V mouth and hand-operated direction valve B mouth (being dissengaged positions because having check valve and main valve plug from V mouth to C mouth direction in sequence valve), hydraulic oil can only enter from hand-operated direction valve B mouth, now hand-operated direction valve B mouth connects with T mouth, hydraulic oil outflows back to fuel tank from T mouth.(now enabling cylinder piston rod promotes back door hinge arm, it is achieved back door breakdown action).When enabling oil cylinder reaches the limit of position; the pressure of oil pump P mouth is gradually increasing; and hydraulic oil cannot release; now hydraulic oil can only promote overflow valve main valve plug by overflow valve internal feedback mouth; overflow valve P mouth is made to connect with T mouth; hydraulic oil outflows back to fuel tank from overflow valve T mouth, to reach the effect of protection system.
When hand-operated direction valve pushes first to, hand-operated direction valve P mouth is connected with B mouth, A mouth is connected with T mouth, hydraulic oil simultaneously enters enabling cylinder upper cavity oil and the second sequence valve V mouth, now the second sequence valve V mouth cannot connect (being dissengaged positions because having check valve and main valve plug from V mouth to C mouth direction in sequence valve) with C mouth, hydraulic oil can only enter enabling cylinder upper cavity oil, promotes piston action；The hydraulic oil of enabling oil cylinder cavity of resorption flows out simultaneously, enter the first sequence valve C mouth, flow through sequence valve internal one-way valve, flow out from the first sequence valve V mouth, simultaneously enter hydraulic control one-way valve V mouth and hand-operated direction valve A mouth, (because locking cylinder cavity of resorption has hydraulic oil in one section of loop of hydraulic control one-way valve V mouth, and without oil-out), hydraulic oil can only flow into hand-operated direction valve A mouth, and now hand-operated direction valve A mouth connects with T mouth, and hydraulic oil outflows back to fuel tank from T mouth.(now enabling cylinder piston rod pulls back door hinge arm, it is achieved back door closed action)；nullWhen enabling oil cylinder reaches the limit of position，Hydraulic fluid pressure in enabling cylinder upper cavity oil to this section of loop of oil pump P mouth gradually rises，When this force value reaches the force value that the second sequence valve is arranged，Internal main valve plug will be promoted to open by the pressure feedback mouth in the second sequence valve，So that the V mouth of the second sequence valve connects with C mouth，Now hydraulic oil flows out from the second sequence valve C mouth，Enter locking cylinder epicoele and hydraulic control one-way valve hydraulic control mouth Pil，Because the oil circuit between locking cylinder cavity of resorption to hydraulic control one-way valve V mouth is closing oil path，The piston akinesia of locking cylinder，The hydraulic fluid pressure flowing simultaneously into locking cylinder epicoele and hydraulic control one-way valve Pil mouth gradually rises，When force value reaches when arranging value of hydraulic control one-way valve，Hydraulic oil opens hydraulic control one-way valve by Pil mouth，Hydraulic control one-way valve C mouth is connected with V mouth，Now locking cylinder piston starts action，The hydraulic oil of locking cylinder cavity of resorption flows out through hydraulic control one-way valve V mouth，Enter and manually change A mouth，Now hand-operated direction valve A mouth connects with T mouth，Hydraulic oil outflows back to fuel tank from T mouth.(now locking cylinder piston rod pulls latch hook action by connecting fork and connecting rod, it is achieved back door locking action).When locking cylinder reaches the limit of position; the pressure of oil pump P mouth is gradually increasing; and hydraulic oil cannot release; now hydraulic oil can only promote overflow valve main valve plug by overflow valve internal feedback mouth; overflow valve P mouth is made to connect with T mouth; hydraulic oil outflows back to fuel tank from overflow valve T mouth, to reach the effect of protection system.
