SUCTION DAMPENING DEVICE WITH INTERNAL DAMPENING FOR VEHICLE AIR CONDITIONING COMPRESSOR

A suction dampening device comprises a housing with an inlet port formed therein and a valve case disposed adjacent the inlet port. The valve case includes at least one opening formed therein. A valvecore is slidably disposed within the valve case. A lever having an axis of rotation fixed to a portion of the valve case includes a first lever arm disposed to a first side of the axis of rotation and a second lever arm disposed to a second side of the axis of rotation. The second lever arm abuts an outer circumferential surface of the valve core. A spring element is disposed between the first lever arm and the valve core. The spring element is configured to apply a force to the first lever arm to cause the second lever arm to apply a lateral force to the valve core to dampen vibrations of the spring element. 本发明提供了种抽吸式阻尼装置，其包括壳体和阀壳，其中，该壳体具有形成在其中的入口端口，阀壳临近于入口端口设置。阀壳包括形成在其中的至少个开口。在阀壳内以可滑动的方式设置有阀芯。具有旋转轴线并固定至阀壳的部分的杆包括第杆臂和第二杆臂，其中，第杆臂设置在旋转轴线的第侧，第二杆臂设置在旋转轴线的第二侧。第二杆臂抵接阀芯的外周表面。在第杆臂与阀芯之间设置有弹簧元件。弹簧元件构造成向第杆臂施加力以使第二杆臂向阀芯施加侧向
