摘要： An Active Roll Control System for a motor vehicle that utilizes small valves to control large flows. Flow is supplied by a hydraulic pump which is powered in some fashion by the motor vehicle. Flow is directed to the actuators by a threeposition four-way valve that is controlled by two pairs of small ABS style solenoid valves. This allows for a minimum of power to be supplied by the vehicle to operate the system. Also, this valve arrangement allows a desirable failure mode whereby hydraulic fluid is locked into the hydraulic actuators, there by locking in the anti-roll bar in case of a system failure.

摘要： The invention relates to a hydraulic steering system (1) with a hydraulic steering unit (2), a priority valve (4), a pump (3), which is connected with the steering unit (2) via a supply line (16), in which the priority valve is arranged (4), and with a load-sensing system and at least one additional pressure sink (5), which is connected with the priority valve (4). In this connection it is endeavoured to ensure the steering, also when the pressure sink has a consumption of load-sensing pressure. For this purpose, the load-sensing system has a first load-sensing line (9), with a pressure (LS) determined by the steering unit, which pressure determines the position of the priority valve (4), and a second load-sensing line (13), which is connected on the one side with the control input (6) of the pump (3) and the additional pressure sink (5) and on the other side with a point in the supply line (16), means being provided for the adaptation of the pressure in the second load-sensing line (13) to the pressure in the first load-sensing line (9).

摘要： The device designed to be fitted on the compressor actuating system of vehicle air-conditioning units has been conceived as a new system to actuate the compressor of vehicle air-conditioning units and it affords incredible additional advantages as it provides a uniform temperature inside the vehicle because the compressor (4) is not actuated by the engine of the vehicle but rather by the pump of the hydraulic steering system (3) as such the speed or the rotation of the motor will not influence the performance of the equipment; a further advantage is that the new system utilises a small hydraulic motor (1), which is turn is actuated by the excess oil pressure generated by the pump of the hydraulic steering system (3), which at present is systematically purged through relief valves and this, in fact, is a waste of power. As already mentioned, the load on the engine will be smaller and consequently its power will increase. This will result in greater economies and improved performance. All the advantages mentioned above have not take into account the fact that the compressor (3) and hydraulic motor (1) set are not installed in the engine compartment where very high temperatures occur, and as such the durability and efficiency of the system are considerably increased.
摘要翻译：设计为安装在车辆空调单元的压缩机致动系统上的装置已经被认为是用于致动车辆空调装置的压缩机的新系统，并且它提供了令人难以置信的附加优点，因为其在车辆内部提供均匀的温度，因为压缩机（4）不由车辆的发动机驱动，而是由液压转向系统（3）的泵致动，因此电机的速度或旋转不会影响设备的性能; 另一个优点是新系统使用小液压马达（1），该液压马达（1）由液压转向系统（3）的泵产生的过量油压致动，液压转向系统（3）的泵当前通过溢流阀被系统地清除，这其实是浪费权力的。如已经提到的，发动机上的负载将更小，因此其功率将增加。这将导致更大的经济和更好的表现。上述所有优点没有考虑到压缩机（3）和液压马达（1）的组合没有安装在发生非常高的温度的发动机室中，因此系统的耐久性和效率显着增加。

摘要： In vehicles including both a hydraulic actuated fuel injection system (A-10) and a traditional power steering system (A-24), the present invention utilizes a single hydraulic pump (A-42) to power both systems to increase engine efficiency and reduce engine part count. Likewise, the present invention utilizes a single hydraulic pump to power both a hydraulic system and a fan drive system in engines including both engine subsystems. Further, for vehicle engines including passenger compartment heating systems, the present invention increases engine efficiency by allowing the heating system to operate effectively, even shortly after a cold start.

摘要： Known priority valves comprise a control valve for damping the movement of a regulating piston. A piston of this type has a very complex construction and is expensive to produce. The invention therefore proposes a selectable control valve (29), whose non-spring loaded side is connected to the feed line (13) and whose spring loaded side is connected to the pressure chamber of the non-spring loaded side of the regulating piston (22).

摘要： The invention starts from a hydraulic system for a motor vehicle and comprises the following elements: a hydraulic pump (10) which has a hydraulic steering device (21) comprising a steering motor (26) and a steering valve (25) which can move from an intermediate position in opposing directions and by which hydraulic fluid lines to and from the steering motor (26) can be controlled; a ventilator motor (17) which is circumvented by a bypass line and fitted in series with the steering device (21) between the latter and the hydraulic pump (10); and a bypass valve (32, 33) with which the distribution of fluid flow through the ventilator motor (17) and the bypass line (31) can be adjusted in accordance with the cooling power required. The aim is to achieve a particularly inexpensive design for a hydraulic system of this type. This is achieved by the feature according to which the bypass valve (32, 33) can be adjusted to allow more hydraulic fluid to flow through the bypass line (31) during actuation of the steering valve (25). This makes it possible to keep the system pressure low and thus to use a simple and inexpensive hydraulic pump (10). No additional valves are required.

摘要： A hydraulic control system (1) for work vehicles including a control unit (2) to control the steering wheels of a vehicle via a cylinder (3) and a priority valve (4) which by means of a first load-sensing system (LS1) controls the pressure fluid flow to the control unit (2) and to a subsequent proportional valve group (9a-9c). By means of a second load-sensing system (LS2) the proportional valve group (9a-9c) controls the pressure fluid flow to secondary hydraulic motors (10) or work cylinders (11, 12) to control the work tools of the vehicle. The control system (1) also includes an open-centre valve connection (6) and a fixed displacement pump (8). The first load-sensing system (LS1) is connected with a second load-sensing system (LS2), whereby drop-off of the pressure fluid flow to the control unit (2) is avoided at simultaneous operation of the latter and of one or several of the proportional valves (9a-9c) as it is the case with known control systems. Hereby a control system is provided which is particularly agreeable to operate for the driver of the work vehicle.

摘要： The proposal is for an electro-hydraulic steering assister with a measuring device to detect the steering moment applied by the driver, an electronic control device (17), a hydraulic supply unit (1), a pilot valve arrangement (7) and a working cylinder (6) coupled to the mechanical steering gear, the working chambers (10, 11) of which can be pressurised depending on the steering direction, whereby the pilot valve arrangement is controlled by the electronic control device. In order to match the hydraulic assistance simply, economically and in the best possible way to the dynamic driving conditions, a proportional pressure control valve (4) is fitted in the connection between the hydraulic supply unit (1) and the working cylinder (6) which can be controlled by the electronic control device (17).

摘要： This invention relates to a hydraulic circuit device of a construction vehicle equipped with an excessive pressure oil control circuit (50) in order to reduce a pressure loss when all the operation valves of a work machine are at neutral positions, to reduce power consumption of a hydaulic pump as a whole when a small amount of pressure oil is necessary for a hydraulic circuit of the work machine, to make it possible to effect arbitrarily an unload instruction of the excessive pressure oil and to make it easier to adjust the change of a flow rate at the time of valve switching. This excessive pressure oil control circuit includes a pilot operated unload valve (11) disposed inside an excessive pressure oil supply pipe (51) connected between a hydraulic pump (P1) dedicated to the work machine and a drain pipe (Ct) through a check valve (20) and a pilot pressure change-over valve (12) disposed inside one of pilot pipes (19) for this unload valve.
