摘要： A chair elevating/lowering hydraulic device includes at least a foot pump 3 which absorbs oil by an ascent of an operation lever 1, which discharges oil stored by a stepping-on of the operation lever, and which discharges stored oil by a stepping-on of the operation lever to a lowest position, a check valve 5 which is opened by the oil pressure of the oil discharged from the foot pump, which is opened when the foot pump is lowered to the lowest position, and which allows the oil from the non-return side to pass to allow it to return to an oil tank through the foot pump, an elevating/lowering cylinder 7, and an accumulator 6.

摘要： In order to solve a problem in a conventional device in which an operation lever is stepped on by a foot to supply oil to an elevating/lowering cylinder, in that since oil supply to the elevating/lowering cylinder is stopped every time the operation lever is stepped on, a seat part stops every time oil supply to the hydraulic cylinder is stopped, and in that such a device gives the person who receives technician's work shock and an uncomfortable feeling, a chair elevating/lowering hydraulic device is composed of a foot pump 3 which absorbs oil by an ascent of an operation lever 1, which discharges oil stored by a stepping-on of the operation lever, and which discharges stored oil by a stepping-on of the operation lever to a lowest position, a check valve 5 which is opened by the oil pressure of the oil discharged from the foot pump, which is opened when the foot pump is lowered to the lowest position, and which allows the oil from the non-return side to pass to allow it to return to an oil tank through the foot pump, an elevating/lowering cylinder 7 which is for elevating/lowering a seat part and which is coupled with the non-return side of the check valve through flow rate regulating means such as an orifice or the like, and an accumulator 6 coupled in parallel with the flow rate regulating means in the non-return side of the check valve.
摘要翻译：为了解决在操作杆由脚踩踏以向升降缸供给油的传统装置中的问题，因为每当操作杆为止时，停止向升降缸的供油停止踩踏时，每当液压缸供油停止时，座椅部分停止，并且由于这种装置给予接收到技术人员的工作震动和不舒服的感觉的人，所以升降升降液压装置由脚踏泵 3，其通过操作杆1的上升吸收油，其通过操作杆的踩踏而排出储存的油，并且通过操作杆的步进将储存的油排出到最低位置;止回阀5 其由从脚泵排出的油的油压打开，当脚泵下降到最低位置时，其被打开，并且允许来自不返回侧的油通过以允许其返回到通过脚泵的油箱，用于升降座椅部件的升降缸7，其通过诸如孔口等流量调节装置与止回阀的止回侧联接，以及与止回阀的止回侧中的流量调节装置并联连接的蓄能器6。

摘要： A plurality of first joint tubes 40 connected to a plurality of heat transfer tubes 3 and a plurality of second joint tubes 50 provided at a header 5B are connected to each other at joints J. The joints J include at least one slide joint Ja at which respective ends of the first and the second joint tubes 40 and 50 are fitted to each other slidably in a predetermined direction. The joints J further include at least one butt joint Jb at which an end of either one of the first and the second joint tubes butts against a sealing surface provided at the other one of the first and the second joint tubes. The butt position of the sealing surface and the end is variable in a direction crossing the predetermined direction. With this arrangement, the influence of an error in the arrangement of the first and the second joint tubes 40 and 50 is reduced, so that the header 5B is properly connected to the heat transfer tubes 3 detachably, and the maintenance of the heat exchanger HE is facilitated.
摘要翻译：连接到多个传热管3的多个第一接合管40和设置在集管5B处的多个第二接头管50在接头J处彼此连接。接头J包括至少一个滑动接头Ja，其中第一和第二接头管40和50的相应端部沿预定方向可滑动地彼此嵌合。接头J还包括至少一个对接接头Jb，其中第一和第二接头管中的任一个的端部抵靠设置在第一和第二接头管中的另一个上的密封表面。密封面和端部的对接位置在与规定方向交叉的方向上是可变的。利用这种布置，减小了第一和第二接头管40和50的布置中的误差的影响，使得集管5B可拆卸地适当地连接到传热管3，并且热交换器HE的维护方便了
