    • PROBLEM TO BE SOLVED: To provide a cylindrical screen which is easily inserted into a horizontal well or an inclined well, and prevents damage or clogging of slits formed therein. SOLUTION: The cylindrical screen (1) is formed of a plurality of support rods (2), and a spiral wire (3). The support rods (2) extend in a screen axial direction and arranged at predetermined intervals in a screen circumferential direction. The spiral wire (3) is arranged on the outside of the support rods (2) and wound about the same in a manner forming slits at predetermined intervals. The cylindrical screen (1) has a plurality of skin rods (4) welded to an outer peripheral surface of the spiral wire (3) in a manner extending in the screen axial direction and being arranged at predetermined intervals in the screen circumferential direction. Each skin rod (4) is formed of a metal. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:提供一种易于插入水平井或倾斜井的圆柱形筛网,并且防止在其中形成的狭缝的损坏或堵塞。 解决方案:圆筒形筛网(1)由多个支撑杆(2)和螺旋丝(3)形成。 支撑杆(2)在丝网轴向延伸并且以丝网周向的预定间隔布置。 螺旋线(3)布置在支撑杆(2)的外侧上,并以预定间隔形成狭缝的方式缠绕在其上。 圆筒形筛网(1)具有多个在丝网轴向延伸的方式焊接在螺旋丝(3)的外周面上的表皮杆(4),并且以规定的间隔配置在丝网圆周方向上。 每个皮肤杆(4)由金属形成。 版权所有(C)2004,JPO

    • PURPOSE: To form a filter having first and second filter elements and a heat exchanger into an integral body by forming in a heat exchange a sub-flowpath which communicates with the second filter element of the filter.
      CONSTITUTION: In a heat exchanger B are formed an oil communication passage C, a main oil flow-in path D for introducing a lubricating oil which has been filtrated and become pure by a first filter element 1 to carry out heat exchange in the heat exchanger B, and sub oil flow-in path E which introduces the lubricating oil which has been filtrated by the second filter element 4 of the filter A. The lubricating oil containing carbon minute particles in the lubricating part of an internal combustion engine reaches an oil flowpath of the filter A from an oil flow-in path 57a of a mounting member 57 via the oil communication path C. A part of oil passes through a communicating hole 3b of the member 3 and flows into the first filter element 1, and another part of oil passes through a filter paper 21 on the upstream end and flows into the second filter element 4. Thereafore, a pipe which prevents the integral loading of the heat exchanger and the filter, can be removed and the heat exchanger and the filter can be formed into an integral body.
