摘要： Methods and systems for operating an absorber-replenisher to supply fluid to a low pressure circuit in a hydrostatic circuit or recover surplus energy usually wasted across a pressure relief valve in the low pressure side by intensifying it for use in a high pressure circuit in the hydrostatic circuit. The absorber-replenisher 1) allows fluid flow through a high pressure motor-pump section of the absorber-replenisher from a high pressure circuit source causing a low pressure motor-pump section to turn providing additional fluid flow to the hydrostatic circuit, or 2) allows increased fluid flow from the low pressure portion of the hydrostatic circuit to increase pressure until the higher pressure induces a higher net torque of the low pressure motor-pump section to reverse the direction of the absorber-replenisher and pump fluid flow into a high pressure circuit through the high pressure motor-pump section.

摘要： A hydraulic motor is driven by a fixed displacement, three stage gear-type pump. The three equal displacement sections provide 3 equally-stepped flows so that the hydraulic motor can have three speeds. Valving and controls are provided for remote on-the-fly shifting of the speeds, automatic pump unloading in neutral, and adjustable maximum pressure. A closed loop system permits use of a relatively small reservoir. The contamination tolerance of the system is greater than that of variable displacement piston-type pumps typically used. Direct recirculation of hydraulic fluid is provided for unused speeds to permit hydraulic fluid to recirculate in the pump without doing work. A unique control circuit is provided to control the first speed valve in conjunction with a logic cartridge which controls hydraulic motor direction to permit fluid flow to the hydraulic motor to be stopped when coming to neutral without slamming the hydraulic motor and rotating drill pipe to a stop. The first speed valve also acts as a relief valve to provide a mechanism for adjusting maximum system pressure.

摘要： A machine includes a hydraulic fan system for circulating cooling air through an engine compartment. Periodically, the fan rotation direction is briefly reversed in order to dislodge any material debris that may have accumulated at the inlet to the engine compartment. When a fan reversal event is initiated, the fan motor will continue to rotate due to angular momentum even after the pump output flow has been switched from a first motor port to a second motor port. During this continued rotation as the fan decelerates to zero speed, vacuum pressure levels can arise at the first motor port, and a pressure spike can develop at the second motor port. In order to alleviate these conditions, a pressure transfer valve briefly opens to facilitate fluid flow directly from the second motor port to the first motor port as the fan motor decelerates towards zero speed before reversing direction, simultaneously alleviating vacuum and pressure spike conditions.
摘要翻译：机器包括用于使冷却空气通过发动机室循环的液压风扇系统。周期性地，风扇旋转方向被短暂地反转，以便消除可能在发动机舱的入口积聚的任何材料碎屑。当启动风扇反转事件时，即使在泵输出流量从第一个电机端口切换到第二个电机端口之后，风扇电机也会由于角度动量而继续旋转。在风扇减速到零速度期间的持续旋转期间，在第一马达端口处可能产生真空压力水平，并且可以在第二马达端口处产生压力尖峰。为了减轻这些条件，压力传递阀短暂地打开，以便随着风扇马达在反转方向之前向零速度减速，同时减轻真空和压力尖峰条件，便于流体从第二马达端口直接流到第一马达端口。

摘要： A pressure selector valve (13) is provided between a hydraulic motor (1) and a directional control valve (5) to connect one of the main conduits (4A), (4B) on a high pressure side to a high pressure conduit (14) while connecting the other of the main conduits on a low pressure side to a low pressure conduit (15). As an inertial body approaches a stop position, a spool valve (16) is switched to an open position (e), bringing a branch passage (14A) of the high pressure conduit (14) into communication with the low pressure conduit. When the pressure difference between the main conduits becomes small, the pressure selector valve is automatically returned to a neutral position to cut off communication between the main conduits, suppressing a reversing movement of the hydraulic motor so that an inertial body can be brought to a stop smoothly.

摘要： A hydrostatic drive system has a consumer (7), in particular a hydraulic motor, located in the open circuit. Associated with the consumer (7) is at least one pressure limiting device (11a; 11b) that can be actuated in the braking phase for the generation of a braking pressure that is present on the discharge side of the consumer (7) from a minimum response pressure in the direction of an increase of the response pressure. A feeder device (12a; 12b) provides a feed of pressure fluid into the admission side of the consumer (7). The pressure limiting device (11a; 11b) and the feeder device (12a; 12b) are integrated into a valve unit (10a; 10b).
