摘要： A closed hydrostatic circuit (10) with variable charge and variable flushing systems is disclosed. A variable displacement charge pump (47) is configured to supply charge fluid and pilot control fluid to the hydrostatic circuit. An electronically controlled pressure regulating valve (43) is in communication with an output of the charge pump (47) and is linked to a controller (41). When the hydrostatic control system (10) detects a high hydraulic temperature condition, the electronically controlled pressure regulating valve (43), that is in communication with an output of the charge pump (47) and that is linked to a controller (41), increases the charge pump (47) flow. A bidirectional variable displacement hydrostatic motor (14) is connected in parallel to two input/output lines (16). A flush valve (15) is in communication with the hydrostatic motor (14) and both input/output lines (16). The flush valve (15) and hydrostatic motor (14) are both in communication with the flush orifice and a flush relief valve (22). When the pressure regulating valve (43) causes the charge pump (47) to operate at or near a full capacity, fluid exits the flush valve (15) and passes through both the flush orifice and the flush relief valve (22). In contrast, when the pressure regulating valve (43) causes the charge pump (47) to operate at a lower or near minimum capacity, fluid exits the flush valve (15) and passes through the flush orifice only without passing through the flush relief valve (22).

摘要： A hydraulic system and methods for conserving energy in such system is disclosed. The hydraulic system includes a hydraulic actuator having a head end, a rod end and a piston disposed therebetween. The system also includes a pump that pumps fluid to the actuator, a first valve disposed downstream of the rod end, and a second valve disposed between the pump and the head end of the actuator.

The combined fluid including fluid received from the pump and fluid received from the rod end of the actuator. When the system is in the light resistive load condition, the second valve is open to allow the combined fluid to flow through the second valve.

摘要： A manner of managing operation of a machine (100) is described for preventing damage/wear to movable machine components arising from operation of the machine/parts at excessive speed while the machine (100) is traveling down a steep incline. The managing of the machine operation includes determining a downhill slope value (THETA) in a machine direction of travel and then establishing a maximum commanded transmission output speed (max commanded motor speed) in accordance with the determined downhill slope value (THETA). Thereafter a maximum commanded gear ratio is established, for a transmission having a variable gear ratio, based upon the maximum commanded transmission output speed (max commanded motor speed) and a current engine speed. A controller compares the maximum commanded variable gear ratio to an operator requested gear ratio, and a target gear ratio is established for the variable gear ratio of the transmission based upon a minimum of the compared commanded variable gear ratio and the operator requested gear ratio.
摘要翻译：描述了一种管理机器（100）的操作的方式，用于防止当机器（100）沿着陡峭的倾斜行进时以超速运转引起的对机器/部件的运动造成的损坏/磨损。机器操作的管理包括确定行进方向上的下坡坡度值（THETA），然后根据确定的下坡坡度值（THETA）建立最大指令传输输出速度（最大指令电机速度）。此后，基于最大指令传输输出速度（最大指令电机速度）和当前发动机转速，建立具有可变齿轮比的变速器的最大指令齿轮比。控制器将最大指令可变齿轮比与操作员所要求的齿轮比进行比较，并且基于所比较的指令可变齿轮比和操作者所要求的齿轮比的最小值，确定变速器的可变齿轮比的目标齿轮比。

摘要： A variable capacity plunger pump (10) includes a housing assembly (15) defining a housing bore (67) that may be configured to receive a liner (73) along at least a portion of the housing bore. An axial plunger (14) slidably disposed within the housing bore (67) to form a compression chamber disposed between a distal end (21) of the plunger (14) and the outlet (12). The compression chamber is in axial alignment with the outlet (12). The plunger (14) is configured to receive fluid from the inlet (25) and pass fluid to the compression chamber. When the plunger (14) is at a first position, the compression chamber is at a first volume to receive fluid from the plunger (14) at a first pressure. When the plunger (14) is at a second position, the compression chamber is at a smaller second volume to pressurize the fluid within the compression chamber to a higher second pressure. The fluid at the second pressure is discharged from the compression chamber into the outlet (12).

The control valve (37) also including a load signal line (45) providing communication between an outlet (18) of the control valve (37) upstream of the inlet (29) and the closed end (46) of the spool (43). Wherein high pressure in the load signal line (45) allowing the control valve (37) to move towards a closed position thereby overcoming bias of the biasing member (48) and reducing flow to the inlet (29) during a high pressure condition.
