    • A control valve is configured such that as a position of a high pressure-side valve body positioned by a solenoid is closer to one side, a degree of opening for communication of a high pressure valve portion is more widened and a pressure on the side of a discharge flow path acting on the high pressure-side valve body is weakened. Further, the control valve is configured such that as a position of a low pressure-side valve body positioned by the solenoid is closer to the other side, a degree of opening for communication of a low pressure valve portion is more widened. When the high pressure-side valve body and the low pressure-side valve body are integrally positioned on the one side by the solenoid and the low pressure-side valve body is positioned on the other side by the solenoid, the high pressure-side valve body and the low pressure-side valve body are separated from each other.
    • 控制阀被构造成使得当由螺线管定位的高压侧阀体的位置更靠近一侧时,高压阀部分的连通的开度更加扩大,并且在侧面的压力 作用在高压侧阀体上的排出流路变弱。 此外,控制阀被构造成使得当由螺线管定位的低压侧阀体的位置更靠近另一侧时,低压阀部分的连通的开度更大。 当高压侧阀体和低压侧阀体通过螺线管一体地定位在一侧时,低压侧阀体由螺线管位于另一侧时,高压侧阀 主体和低压侧阀体彼此分离。
