    Abstract: The kit of the present invention is for use in the refilling within a survival unit of a gaseous supply tank through a filler valve having a threaded stem adjacent the free end thereof and a gripping surface on the filler valve. The gas is generally oxygen although other gas may be supplied. The kit includes an adapter to provide coupling relationship with the threaded stem of the filler valve so as to permit a flow of oxygen into the supply tank such that refilling thereof may take place without removal of the supply tank from the survival kit. The adapter includes an elongated member with an aperture extending therethrough and is adapted to mate with the filler valve in sealing engagement therewith so as to permit gas flowing through the aperture to enter the filler valve. The adapter further includes a holder with a bore extending axially therethrough and the elongated member extends axially through the aperture. A gripping section is provided on the adapter so as to obtain a coupling to the threaded stem such that rotation of the holder by means of the gripping section obtains abutting sealing engagement between the member and the filler valve. A wrench adapted to be used in conjunction with the adapter is provided as part of the kit. The wrench includes a socket for enclosing the gripping surface to provide retention of the filler valve in fixed position as the member is releasably coupled to the filler valve.

    Abstract translation: 本发明的试剂盒用于通过具有邻近其自由端的螺纹杆的加注阀和填充阀上的夹紧表面在气体供应罐的存活单元内重新填充。 气体通常是氧，尽管可以提供其它气体。 该套件包括适配器，以提供与填充阀的螺纹杆的耦合关系，以便允许氧气进入供应罐，使得可以在不从存活试剂盒中取出供应罐的情况下进行再充填。 适配器包括细长构件，其具有延伸穿过其中的孔，并且适于与填充阀配合以与其密封接合，以允许气体流过孔径进入填充阀。 适配器还包括具有轴向延伸穿过其中的孔的保持器，并且细长构件轴向延伸穿过孔。 夹持部分设置在适配器上，以便获得与螺纹杆的联接，使得夹持器通过夹持部分的旋转获得构件和填充阀之间的邻接的密封接合。 作为套件的一部分提供了适合与适配器配合使用的扳手。 扳手包括用于封闭抓握表面的插座，以在填充阀可释放地联接到填充阀时将填充阀保持在固定位置。

    Abstract: A maximum liquid level control valve for limiting the flow of liquid petroleum gas into a tank having a valve body, a float pivotally attached to the valve body, a closure flap, a spring acting between the valve body and the closure flap, and a cam device movable by the float. The control valve which is mounted to a flange welded to the side wall of the tank has a valve seat and a passage for liquid to flow through the valve body into the tank. The closure flap is movable toward the valve seat to a closed position and away from the valve seat to an open position. The closure flap is movable to the closed position under incoming liquid pressure. When the liquid level in the tank is below the maximum liquid level, the cam device acts on a stem which is attached to the closure flap. With the cam acting on the stem, the closure flap cannot be moved to the closed position in response to incoming liquid pressure. When the maximum liquid level is reached, the cam device rotates unblocking the stem, the spring constant of the spring is overcome by incoming liquid pressure, and the closure flap is moved to the closed position. When the tank is filled, the source of liquid petroleum gas is shut off and any pressure trapped within the control valve and working against the closure flap is released through a bleeder hole. Then the spring returns the closure flap from the closed position to the open position.

    Abstract translation: 用于限制液体石油气流入具有阀体的罐的最大液位控制阀，枢转地连接到阀体的浮子，封闭翼片，作用在阀体和封闭翼片之间的弹簧以及凸轮 装置由浮子移动。 安装到焊接到罐的侧壁的法兰上的控制阀具有阀座和用于液体流过阀体的槽的通道。 闭合翼片可朝向阀座移动到关闭位置并远离阀座到达打开位置。 封闭翼片在进入的液压下可移动到关闭位置。 当罐中的液位低于最大液位时，凸轮装置作用在连接到封闭盖上的杆上。 当凸轮作用在杆上时，闭合翼片不能响应于进入的液体压力而移动到关闭位置。 当达到最大液位时，凸轮装置使杆脱开，弹簧的弹簧常数通过进入的液压来克服，并且闭合盖移动到关闭位置。 当罐被填充时，液体石油气源被关闭，并且在控制阀内捕获的任何压力并且抵靠闭合盖通过泄放孔释放。 然后弹簧将闭合盖从关闭位置返回到打开位置。
