    • A communication control method accomplishes minimum bandwidth guarantee and maximum bandwidth restriction and further allocates an extra-bandwidth in accordance with user's contact bandwidth. Fixed-length packets are once stored in corresponding partitions of a buffer in accordance with connection information contained in the packets and then transmits the packets from the storage sections in succession. Retrieval of a connection where the number of transmitted packets does not reach a lower-limit throughput and a packet to be transmitted exists in the corresponding partition is made with first priority, and retrieval is further made in order for a connection where the number of transmitted packets does not reach an intermediate throughput and a connection where the number of transmitted packets does not reach an upper-limit throughput. If the retrieval shows a hit connection, the packets are transmitted from the corresponding partition and one-time retrieval comes to an end.
    • 通信控制方法实现最小带宽保证和最大带宽限制,并根据用户的接触带宽进一步分配额外带宽。 固定长度的数据包根据数据包中包含的连接信息一次存储在缓冲器的相应分区中,然后连续发送存储部分的数据包。 在对应的分区中存在传送分组数目未达到下限吞吐量和分组的连接的检索以第一优先级进行,并进一步进行检索,以进行连接,其中发送的数量 分组没有达到中间吞吐量和传输分组数未达到上限吞吐量的连接。 如果检索显示命中连接,则从相应的分区发送分组,一次性检索结束。

    • A first bleed passage and a second bleed passage each connect a crank chamber of a compressor with a suction chamber of the compressor. A first supply passage and a second supply passage each connect the crank chamber with a discharge chamber of the compressor. A first control valve adjusts the opening size of the first supply passage in response to the pressure in the suction chamber. A second control valve includes a ball valve and an electromagnetic actuator. The ball valve adjusts the opening size of the second supply passage and the opening size of the first bleed passage. The electromagnetic actuator moves the ball valve. The ball valve is moved to a first position and to a second position. At the first position, the ball valve closes the second supply passage and opens the first bleed passage. At the second position, the ball valve opens the second supply passage and closes the first bleed passage. A displacement control device, which includes the first and second control valves, readily and reliably changes the displacement of the compressor.
    • 第一排放通道和第二排放通道各自连接压缩机的曲轴室和压缩机的吸入室。 第一供给通路和第二供给通路将曲柄室与压缩机的排出室连接。 第一控制阀响应于吸入室中的压力来调节第一供给通道的开口尺寸。 第二控制阀包括球阀和电磁致动器。 球阀调节第二供给通道的开口尺寸和第一排出通道的开口尺寸。 电磁执行器移动球阀。 球阀被移动到第一位置和第二位置。 在第一位置,球阀关闭第二供给通道并打开第一排出通道。 在第二位置,球阀打开第二供给通道并关闭第一排出通道。 包括第一和第二控制阀的排量控制装置容易且可靠地改变压缩机的排量。
