摘要： A fixed capacity pump (P) sucks working oil from a reservoir (R) through a conduit (Rp) and a suction passage (1), and discharges the pressurized working oil into a discharge passage (2) connected to an actuator (A). A choke (21) is disposed in the discharge passage (2), and a flow control valve (F) recirculates a part of the working oil in the discharge passage (2) upstream of the choke (21) to the suction passage (1) according to a pressure loss generated by the choke (21). The characteristic of the choke (21) which significantly increases the flow resistance in a low temperature state makes the flow rate of the recirculated working oil increase, thereby preventing cavitation/noise from occurring in the pump (P) when operated at high speed and in a low temperature state.
摘要翻译：固定容量泵（P）通过管道（Rp）和吸入通道（1）从储存器（R）吸入工作油，并将加压的工作油排放到连接到致动器（A）的排出通道（2）。排气通道（2）中设有扼流器（21），流量控制阀（F）将位于扼流圈（21）上游的排出通道（2）中的一部分工作油再循环到吸入通道）根据由扼流圈（21）产生的压力损失。在低温状态下显着增加流动阻力的扼流圈（21）的特征使得再循环工作油的流量增加，从而防止在高速运转时在泵（P）中发生空化/噪声低温状态。
