    摘要： In order to improve the mountability in an engine, an oil pressure control apparatus includes: a pump that ejects oil by being driven by rotation of an engine; a first flow passage that interconnects the pump and a first predetermined portion; a second flow passage that is branched from the first flow passage and that supplies oil to a second predetermined portion; and a flow passage area adjusting portion that adjusts a flow passage area of the second flow passage according to a pressure of oil in the second flow passage; wherein the flow passage area adjusting portion is configured including a spool that is formed such that a first pressure receiving face and a second pressure receiving face having an area smaller than that of the first pressure receiving face oppose each other with the second flow passage interposed therebetween, and that can move according to a pressure of oil in the second flow passage, and a biasing member that biases the spool in a direction from the first pressure receiving face to the second pressure receiving face.

    摘要翻译： 为了提高发动机的安装性，油压控制装置包括：通过由发动机的旋转驱动而喷射油的泵; 第一流动通道，其将泵和第一预定部分相互连接; 第二流路，其从所述第一流路分支并将油供给到第二预定部分; 以及流路面积调整部，其根据所述第二流路中的油压调整所述第二流路的流路面积; 其特征在于，所述流路面积调整部构成为包括形成为使得第一受压面和所述第二受压面的面积小于所述第一受压面的面积相对的第二流路的卷轴， 并且能够根据第二流路中的油的压力移动;以及偏压构件，其在从第一受压面朝向第二受压面的方向上偏压卷轴。
