    • A closed hydrostatic circuit with variable charge and variable flushing systems is disclosed. A variable displacement charge pump is configured to supply charge fluid and pilot control fluid to the hydrostatic circuit. An electronically controlled pressure regulating valve is in communication with an output of the charge pump and is linked to a controller. When the hydrostatic control system detects a high hydraulic temperature condition, the electronically controlled pressure regulating valve, that is in communication with an output of the charge pump and that is linked to a controller, increases the charge pump flow. A bidirectional variable displacement hydrostatic motor is connected in parallel to two input/output lines. A flush valve is in communication with the hydrostatic motor and both input/output lines. The flush valve and hydrostatic motor are both in communication with the flush orifice and a flush relief valve. When the pressure regulating valve causes the charge pump to operate at or near a full capacity, fluid exits the flush valve and passes through both the flush orifice and the flush relief valve. In contrast, when the pressure regulating valve causes the charge pump to operate at a lower or near minimum capacity, fluid exits the flush valve and passes through the flush orifice only without passing through the flush relief valve.
    • 公开了具有可变电荷和可变冲洗系统的闭合静液压回路。 可变容量电荷泵被配置为向静液压回路供给充液流体和先导控制流体。 电子控制的压力调节阀与电荷泵的输出端连通并连接到控制器。 当静液压控制系统检测到高液压温度条件时,与电荷泵的输出连通并与控制器相连的电控压力调节阀增加了电荷泵的流量。 双向可变排量静液压马达与两条输入/输出线并联。 冲洗阀与静液压马达和两个输入/输出线路连通。 冲洗阀和静液压马达都与冲水孔和冲水安全阀连通。 当压力调节阀使电荷泵工作在满容量或接近满容量时,流体离开冲洗阀并通过冲洗孔和冲洗安全阀。 相反,当压力调节阀使电荷泵以较低或接近最小容量运行时,流体离开冲洗阀并仅通过冲洗孔而不通过冲洗安全阀。
