    • An inflation valve (100) comprises a valve housing (101) having an inner wall (102), a cylindrical inner chamber (103) terminating in a gas outlet (110), and a gas inlet bore (104) providing fluid communication between the inner chamber (103) and a pressurized gas source. A piston (105) enclosed in the inner chamber (103) comprises at one end a head (108) directed toward the gas outlet (110) and at the opposite end a valve actuator connector (106). The piston (105) further comprises a gas inlet seal (112a,112b), positioned between the head (108) and the actuator connector (106), that releasably seals the gas inlet bore (104) from the inner chamber (103) when the piston (105) is in a normal, non-actuated position. A valve actuator (107) connected to the actuator connector (106) operates to pull the piston (105) , thereby moving the gas inlet seal (112a,112b) away from the gas inlet bore (104) and putting the inner chamber (103) in fluid communication with the gas inlet bore (104) and pressurized gas source. A regulating spring (114) contacting the piston close to the actuator connector (106) is compressible by the force of pressure exerted by gas contained within the inner chamber (103) and the gas inlet bore (104) and operates to position the piston (105) to control or regulate the outlet pressure.
    • 充气阀(100)包括具有内壁(102),终止于气体出口(110)的圆柱形内腔(103)和气体入口孔(104)的阀壳体(101),该气体入口孔 内室(103)和加压气源。 封闭在内室(103)中的活塞(105)在一端包括指向气体出口(110)的头部(108),在相对端处包括阀致动器连接器(106)。 活塞(105)还包括位于头部(108)和致动器连接器(106)之间的气体入口密封件(112a,112b),其可将气体入口孔(104)从内腔(103) 活塞(105)处于正常的非致动位置。 连接到致动器连接器(106)的阀致动器(107)操作以拉动活塞(105),从而使气体入口密封件(112a,112b)远离气体入口孔(104)并将内部腔室(103) )与气体入口孔(104)和加压气体源流体连通。 靠近致动器连接器(106)的接触活塞的调节弹簧(114)可通过由内室(103)和气体入口孔(104)中包含的气体施加的压力而被压缩,并且操作以将活塞( 105)以控制或调节出口压力。

    • A liferaft has a floor (52) surrounded by one or more inflatable tubes (50, 51). Two canopies (54a, 54b) are provided, one (54a) covering one side of the floor (52) and the other (54b) covering the other side of the floor (52). When the liferaft is deployed on water, support means, which may be an inflatable column (63), erect the canopy (54a) that is above the water. The other canopy (54b) is unerected and lies in the water. The system of weights (67) and elastic ropes (66) forms the canopy in the water into stabilizing means in the form of water pockets. Similar means are provided on the deployed canopy (54a) but, when the canopy (54a) is erected, they lie flush with the canopy surface and so do not interfere with the operation of the liferaft.
    • 救生筏具有由一个或多个可充气管(50,51)包围的地板(52)。 提供了两个顶篷(54a,54b),一个(54a)覆盖地板(52)的一侧并且另一个(54b)覆盖地板(52)的另一侧。 当救生筏部署在水面上时,支撑装置(可以是可充气柱(63))竖立位于水面上的遮篷(54a)。 另一顶盖(54b)未被修理并位于水中。 重物系统(67)和弹性绳索(66)将水中的顶篷形成水袋形式的稳定装置。 类似的装置设置在展开的顶篷(54a)上,但是当顶篷(54a)竖立时,它们与顶篷表面齐平并且因此不干扰救生筏的操作。
