    • A pressurised fluid cylinder (1) having a shut-off valve, comprising a valve element (6) on a valve stem which is linearly movable. A biasing member (15) exerts a biasing force on the valve element and a crank moves the valve stem. The crank comprises a first linkage (37) pivotally attached at one end to the valve stem and a second linkage (50) pivotally attached at one end to the second end of the first linkage and being positionally fixed but rotatable about the opposite end. Rotation of the first linkage (37) in a first rotational direction initially causes biasing of the biasing member and further rotation of the second linkage causes the linkage to pass a top or bottom dead centre position, at which point a proportion of the energy stored in the biasing member during its biasing causes the first linkage to be biased further in the first rotational direction after the top or bottom dead centre position.
    • 一种具有关闭阀的加压流体缸(1),其包括可直线运动的阀杆上的阀元件(6)。 偏置构件(15)对阀元件施加偏置力,并且曲柄移动阀杆。 曲柄包括在一端枢转地连接到阀杆的第一连杆机构(37)和在一端可枢转地连接到第一连杆机构的第二端的第二连杆机构(50),其位置固定,但可围绕相对端旋转。 第一连杆机构(37)在第一旋转方向的旋转最初引起偏压部件的偏置,并且第二连杆的进一步转动使连杆机构通过顶部或下部死点位置,在该点处存储的能量的一部分 偏置构件在其偏置期间使得第一连杆机构在顶部或底部死点位置之后沿第一旋转方向被进一步偏置。

    • A valve for a pressurised fluid cylinder. The valve comprises a shut off valve (22) biased against a seat (26) to seal the cylinder. An actuation element (31) is movable linearly to open the valve (22) against the biasing force. A linkage element (28) couples the actuation element (31) to the shut off valve (22) and comprises a first piston (30) towards its top and a second piston towards its bottom (34). The valve also comprises a gas refill inlet (14) between the pistons (30; 34) such that refill gas pressure biases the linkage element (28) away from the valve (22). The actuation element (31) in a depressed position pushes against the linkage element (28) to hold the linkage element (28) down and the valve (22) open so that the cylinder can be refilled. When the actuation element (31) is in a non-depressed position, the linkage element (28) is free to move with the refill gas pressure so that it is spaced from the valve (22).
    • 用于加压液压缸的阀。 阀包括偏压阀座(26)以密封气缸的截止阀(22)。 驱动元件(31)可以线性移动以克服偏压力打开阀(22)。 联动元件(28)将致动元件(31)连接到截止阀(22),并且包括朝向其顶部的第一活塞(30)和朝向其底部(34)的第二活塞。 阀还包括在活塞(30; 34)之间的气体再充填入口(14),使得再填充气体压力使连接元件(28)偏离阀(22)。 处于按压位置的致动元件(31)推动联动元件(28)以将联动元件(28)保持在下方并且阀(22)打开,使得气缸可被重新填充。 当致动元件(31)处于非压下位置时,连接元件(28)随着再填充气体压力自由移动,使得其与阀(22)间隔开。
