阀芯52下端所受液压力或推力高于阀芯弹簧53的回复力及上端液压力的合力时，阀芯52向上移动，第二通道孔522通过阀体连通孔512、第一连通透孔13与芯轴1的内腔连通，阀芯52下方的活塞腔40与芯轴1的内腔连通。
When the hydraulic pressure or pushing force on the lower end of the valve core 52 is higher than a combined force of a restoring force of the valve core spring 53 and an upper hydraulic pressure, the valve core 52 moves upward, the second passage hole 522 passes through the valve body communication hole 512 and the first communication through-hole 13 to communicate with the inner cavity of the spindle 1, and the piston cavity 40 below the valve core 52 communicates with the inner cavity of the spindle 1.

The fluid in the inner cavity of the spindle 1 applies a pressure from a pump to the interior of the piston cavity 40 via the communication valve structure 5, and the hydraulic pressure of the fluid pushes the driving cylinder downward to seal the annulus sealing device 91.
进一步，如图1所示，旋转筒33的侧壁上沿周向间隔穿设有多个能径向伸缩的弹性锁块331，在本实施方式中，旋转筒33的侧壁上沿周向间隔设置有多个旋转筒侧透孔，各旋转筒侧透孔内分别穿设一弹性锁块331，各弹性锁块331的径向内侧能径向收缩入旋转筒33的内腔，各弹性锁块331的径向外侧能径向伸出凸出于旋转筒33的外壁，悬挂筒31的内壁上设置有多个键槽，各弹性锁块331能径向伸出且各弹性锁块331的径向外侧能分别卡设于对应的键槽内，活塞41的外壁上位于键槽上方的位置设置有活塞凹槽416，各弹性锁块331能径向收缩且各弹性锁块331的径向内侧能滑设于活塞凹槽416内。
The elastic lock blocks 331 are respectively arranged within the rotating cylinder-side through-holes, radial inner sides of the elastic lock blocks 331 can be radially contracted into the inner cavity of the rotating cylinder 33, and radial outer sides of the elastic lock blocks 331 can radially protrude out of the outer wall of the rotating cylinder 33.
将旋转筒33组装于悬挂筒31内时，首先将旋转筒33沿轴向推入悬挂筒31内，此时各弹性锁块331的径向外侧被径向压缩，当各弹性锁块331与各键槽位于相同轴向位置时，旋转旋转筒33使得各弹性锁块331的径向外侧径向伸出卡设于对应的键槽内，实现旋转筒33与悬挂筒31的固定连接。
When the elastic lock blocks 331 and the key grooves 311 are located at the same axial position, the rotating cylinder 33 is rotated so that the radial outer sides of the elastic lock blocks 331 extends radially and is locked in the corresponding key grooves 311, achieving a fixed connection between the rotating cylinder 33 and the suspension cylinder 31.
深水钻井用套管头与环空密封装置下入工具100组装后，旋转筒33通过螺纹连接套设于活塞41外壁上，旋转筒33能沿活塞41旋转升降，旋转旋转筒33使其上升并使各弹性锁块331离开键槽，旋转筒33上升至各弹性锁块331到达活塞凹槽416位置时，各弹性锁块331径向收缩且其径向内侧滑设于活塞凹槽416内，旋转筒33与悬挂筒31相脱离。
When the rotating cylinder 33 raises until the elastic lock blocks 331 reach the piston grooves 416, the elastic lock blocks 331 radially contract and the radial inner sides thereof slide into the piston grooves 416, thereby the rotating cylinder 33 separating from the suspension cylinder 31.
进一步，如图1所示，旋转筒33位于悬挂筒31外部的一端能转动且轴向固定地套设于一锥套34的外壁顶部，锥套34的外径自上而下呈渐缩设置，旋转筒33能推动锥套34下移将开口锁环42顶抵张开。

锥套34下移能自顶部顶抵开口锁环42使其径向张开，锥套34上移离开开口锁环42使其径向收缩。
The tapered sleeve 34 moves downward to abut against the open type lock ring 42 from the top, to make the open type lock ring 42 radially open, and the tapered sleeve 34 moves upward away from the open type lock ring 42 to make the open type lock ring 42 contract radially.
在本实施方式中，锥套34为对开结构，旋转筒33的外壁底部设有环形凹槽部，锥套34的内壁顶部设置有能卡设于环形凹槽部内的环形凸起部，通过环形凸起部和环形凹槽部的卡设配合，实现旋转筒33转动套设于锥套34的外壁上，且二者之间轴向相对固定，旋转筒33通过该配合将轴向力传递给锥套34，从而实现推拉锥套34上下移动。
Such snap-fitting between the annulus boss part and the annulus groove part allows the rotating cylinder 33 to be rotatably sleeved on the outer wall of the tapered sleeve 34, and the rotating cylinder 33 and the tapered sleeve 34 to be relatively fixed axially.
进一步，如图1所示，锥套34上沿轴向设有至少一个底部开口的锥套豁口透槽，活塞41的外壁上固定设置有与锥套豁口透槽对应的防扭键341，在本实施方式中，防扭键341通过防转螺钉342固定连接于活塞41的外壁上。
Further, as shown in FIG. 1, the tapered sleeve 34 is provided with at least one tapered sleeve open type through slot 343 with a bottom open, in the axial direction.
锥套豁口透槽滑动套设于防扭键341的周向两侧。
The tapered sleeve open type through slot 343 is slidably sleeved on two sides of the anti-torsion key 341 in the circumferential direction.
防扭键341能够有效避免锥套34相对活塞41周向转动，锥套34能在上部旋转筒33的推拉下实现上下移动。
The anti-torsion key 341 can effectively prevent the tapered sleeve 34 from rotating in the circumferential direction relative to the piston 41, and the tapered sleeve 34 can move up and down by pushing and pulling of the rotating cylinder 33 located above the tapered sleeve 34.

Heat exchanger assembly 10 comprises a heat exchanger 12, a thermal valve integration unit 14 and a pressure bypass valve assembly 16.
热交换器12包括多个冲压的热交换器芯板18、20，它们彼此交替、堆叠、钎焊地设置以形成热交换器芯22，并且在堆叠的芯板18、20之间形成有交替的第一流体流动通路和第二流体流动通路24、26。
Heat exchanger 12 is comprised of a plurality of stamped heat exchanger core plates 18, 20 disposed in alternating, stacked, brazed relation to one another to form a heat exchanger core 22, with alternating first and second fluid flow passages 24, 26 formed between the stacked core plates 18, 20.
第一流体流动通路24用于第一热传递流体流，而第二流体流动通路26用于第二热传递流体流。
The first fluid flow passages 24 are for flow of a first heat transfer fluid, and the second fluid flow passages 26 are for flow of a second heat transfer fluid.
在本实施例中，第一热传递流体(在本文中也称为“第一流体”或“油”)是变速器油，而第二热传递流体(在本文中也称为“第二流体”或“冷却剂”)是发动机冷却剂，其通常包括乙二醇或乙二醇/水混合物。
In the present embodiment, the first heat transfer fluid (also referred to herein as the “first fluid” or “oil”) is a transmission oil, and the second heat transfer fluid (also referred to herein as the “first fluid” or “coolant”) is engine coolant, which typically comprises glycol or a glycol/water mixture.
在其它实施例中，第一热传递流体可以是发动油。
In other embodiments, the first heat transfer fluid may be engine oil.
应理解的是，取决于油和冷却剂之间的温度差，冷却剂可以从油吸收热量或将热量传递给油，这取决于机动车辆的运行状态。
It will be appreciated that the coolant may either absorb heat from the oil or transfer heat to the oil, depending on the temperature differential between the oil and coolant, which depends on the operating state of the motor vehicle.
芯板18、20可以彼此相同，其中芯板18、20的交替布置是通过使堆叠中的每隔一个芯板18、20相对于堆叠中的邻近芯板18、20转180度(即，端对端)来提供的。
The core plates 18, 20 may be identical to one another, with the alternating arrangement of core plates 18, 20 being provided by rotating every other core plate 18, 20 in the stack by 180 degrees (i.e. end-to-end), relative the adjacent core plates 18, 20 in the stack.
芯板18、20各自包括在所有侧面上由倾斜的边缘壁30围绕的总体上平面的基部28。
The core plates 18, 20 each comprise a generally planar base portion 28 surrounded on all sides by sloping edge walls 30.
芯板18、20彼此一个堆叠在另一个顶部，并且它们的边缘壁30嵌套、密封地接合。
The core plates 18, 20 are stacked one on top of another with their edge walls 30 in nested, sealed engagement.
每个芯板18、20在其四个角附近设有四个孔32、34、36、38，根据特定应用的需要，这些孔各自用作为用于第一热传递流体或第二热传递流体的入口孔或出口孔。
Each core plate 18, 20 is provided with four holes 32, 34, 36, 38 near its four corners, each of which serves as an inlet hole or an outlet hole for the first or second heat transfer fluid as required by the particular application.
