摘要： A control valve includes: a body having a port communicating with a discharge chamber, a port communicating with a control chamber, and a main valve hole formed in a passage connecting the ports; a main valve element configured to close and open a valve section by moving toward and away from the main valve hole; a solenoid configured to generate a force for driving the main valve element in valve opening and closing directions of the valve section, power supply to the solenoid being controlled according to pulse width modulation (PWM); and a vibration absorbing structure including a spring connected with a plunger configured to be displaced integrally with the main valve element, and a weight connected with the plunger with the spring therebetween in a relatively displaceable manner, and configured to suppress vibration of the main valve element caused by the PWM control.

摘要： A control valve according to an embodiment includes a body having a valve hole and a guiding passage formed coaxially with the valve hole, an actuating rod, slidably supported along the guiding passage, which is provided with a valve element, a solenoid for applying the solenoidal force in an opening or closing direction of a valve section to the valve element via the actuating rod, and a seal section, provided between the actuating rod and the guiding passage, which houses a sealing member for restricting the leakage of refrigerant from a high pressure side to a low pressure side. The actuating rod and the guiding passage are configured such that the clearance, between the actuating rod and the guiding passage, which is at a higher-pressure side of the seal section is larger than the clearance which is at a lower-pressure side of the seal section.
摘要翻译：根据实施例的控制阀包括具有阀孔和与阀孔同轴形成的引导通道的主体，沿着引导通道可滑动地支撑的致动杆，其具有阀元件，螺线管用于施加螺线管通过致动杆将阀部分向阀元件的打开或关闭方向的力;以及设置在致动杆和引导通道之间的密封部分，其容纳用于限制制冷剂从高压泄漏的密封构件一侧到低压侧。所述致动杆和所述引导通道被构造成使得所述致动杆和所述引导通道之间在所述密封部分的较高压力侧的间隙大于所述密封部分的较低压力侧的间隙密封段。
