    • PROBLEM TO BE SOLVED: To make it possible to lower power consumption, and to simultaneously provide optimized control characteristics.
      SOLUTION: In a low speed mode, a directional valve 050 is closed which is disposed in a main line 050L of a low pressure section LPS for leading oil to a lubrication and cooling section LCS of the clutches of a DCT, and two outlets X, Y of a pump means 020 are operated at the same time so that the oil forcibly flows through a check valve 060 disposed in a first branch line 060L of the low pressure section that leads to a high pressure section. In a medium speed mode, on/off pilot pressure for the directional valve is generated, and an on/off valve 040 is operated which is disposed in a connection line 040L branching from the first branch line, to open the directional valve in a main line of the low pressure section LPS. In a high speed mode, the on/off valve of the directional valve is operated to keep the first outlet X of the pump means at a high pressure level and the second outlet Y of the pump means at a low pressure level.

    • 要解决的问题:能够降低功耗并同时提供优化的控制特性。 解决方案:在低速模式下,方向阀050关闭,该方向阀050设置在低压部分LPS的主线路050L中,用于将油引导到DCT的离合器的润滑和冷却部分LCS,以及两个 泵装置020的出口X,Y同时工作,使得油强制地流过设置在低压段的第一分支管线060L中的止回阀060,该第一分支管线060L通向高压段。 在中速模式中,产生用于方向阀的开/关先导压力,并且操作开/关阀040,其设置在从第一分支管分支的连接管线040L中,以主要方式打开换向阀 线的低压部分LPS。 在高速模式中,方向阀的开关阀被操作以将泵装置的第一出口X保持在高压水平,并且泵装置的第二出口Y在低压水平。 版权所有(C)2008,JPO&INPIT
