摘要： Provided is a rail having a simple structure and capable of stably supporting a load caused by a drawer and accommodated matters. The rail has a structure having a resistance against a torsional load that twists the rail in a central direction of the drawer and configured to prevent interference between components of the rail even when the torsional load occurs.

摘要： A vacuum apparatus for easily forming a vacuum in any bottle, container or the like and for providing a stable sealing. A lower cylindrical member together with a disc member forms a space portion in which a vacuum or an atmospheric pressure is applied, and the lower portion of an upper cylindrical member is inserted in the space portion and divides the space portion into upper and lower spaces. With a downward movement of the upper cylindrical member, the upper space expands and draws air inside of a bottle, and with an upward movement thereof, the air introduced into the upper space is vented outside. At this time, a check valve is selectively opened and closed and is operated by a pressure difference applied thereon. By repetitive reciprocating movement of the upper cylindrical member, a high vacuum is formed in the bottle and is sealed by the check valve. The apparatus is adaptable in a vacuum bottle, a medical suction instrument or the like.

摘要翻译： 用于在任何瓶子，容器等中容易地形成真空并提供稳定密封的真空装置。 下部圆柱形构件与盘构件一起形成其中施加真空或大气压力的空间部分，并且上部圆柱形构件的下部插入空间部分中并将空间部分分成上部空间和下部空间。 随着上部圆柱形构件的向下运动，上部空间膨胀并吸入瓶子内的空气，并且随着其向上运动，引入上部空间的空气被排出到外部。 此时，单向阀选择性地打开和关闭，并通过施加在其上的压力差来操作。 通过上部圆柱形部件的重复往复运动，在瓶子中形成高真空度，并由止回阀密封。 该装置适用于真空瓶，医用抽吸器具等。
