摘要： In some steering systems, tractive forces occur in the hydraulic cylinder. If the cylinder is designed with a piston rod at one end only, the piston rod anticipates the steering motion in one steering direction. The result is uncontrolled steering characteristics, with all the dangers that this entails. The solution proposed to this problem consists in fitting, between the control valve (3) in the hydraulic control unit (1) and the space behind the piston head in the cylinder (2), a throttle (10) plus a by-pass line which negates the throttle function for hydraulic fluid passing towards the cylinder (2). The invention is intended for use in hydraulic steering-control units for low-speed vehicles.

摘要： A flow amplifier (1) with an inlet (4) and an outlet (5) is provided, between which a first branch (6), through which a flow of a fluid to be amplified is flowing, with a first throttling device (8), the throttle resistance of which is adjusted in dependence on the pressure across and by the flow rate through the first throttling device, and a second branch (7) with a second throttling device (11), the throttle resistance of which is adjusted in dependence on the throttle resistance of the first throttling device. In a flow amplifier of that kind, the amplification factor is intended to be made independently of pressure losses in the generation of the flow to be amplified. For that purpose, at least one pressure-divider (14, 15; 17, 18) with a central take-off point (16; 19) is provided, which is supplied by a pressure difference between inlet (4) and outlet (5), the pressure at the central take-off point (15, 19) controlling the flow rate through the second throttling device (11).

摘要： The invention relates to a device for actuating the control valve (14) of a hydraulic servo steering system for motor vehicles in which the rotary movement of a steering wheel is transmitted via a control shaft (2) and the steering moment is transmitted via a relative rotation between the control shaft (2) and a pinion shaft (4) and whereby the control valve (14) is a linear slide valve. It is the purpose of the invention to provide a simple device with few components. This is achieved in that there is a sleeve (6) surrounding the control shaft (2) and the pinion shaft (4) which converts the relative rotation between the two shafts into an axial shift owing to the fact that the sleeve (6) has a pair of axially and spirally running connecting link guides (7, 8) with which engage a pair of pins (9, 10) which are solidly secured to the control shaft (2) or the pinion shaft (4). Further embodiments of the invention concern particularly compact or low-friction arrangements. In order to compensate all actuating clearances, it is proposed in an important further embodiment of the invention to fit a prestressing spring (36) to the valve slide (12).
摘要翻译：本发明涉及一种用于致动用于机动车辆的液压伺服转向系统的控制阀（14）的装置，其中方向盘的旋转运动经由控制轴（2）传递，转向力矩通过相对位置传递控制轴（2）和小齿轮轴（4）之间的旋转，由此控制阀（14）是直线滑阀。本发明的目的是提供一种具有很少组件的简单装置。这是通过设置有围绕控制轴（2）和小齿轮轴（4）的套筒（6），其将两轴之间的相对旋转转换成轴向移动，这是因为套筒（6）具有一对轴向和螺旋运行的连接连杆导向件（7,8）与一对牢固地固定在控制轴（2）或小齿轮轴（4）上的销（9,10）啮合。本发明的其它实施例涉及特别紧凑或低摩擦布置。为了补偿所有致动间隙，在本发明的一个重要的另外的实施例中提出将预应力弹簧（36）装配到阀滑块（12）。

摘要： This invention concerns an electrohydraulic control device (10, 60) for a hydraulic control motor for controlling a flow which is built in the form of a 4/2-directional control valve module. A control valve from seat valve technology between a motor connection (B) and a return (R) form a lowering part (11), while the corresponding reset element (44) is carried out in the form of a longitudinal gate valve (45) which controls the connection between an intake connection (P) and a motor connection (A) and is actuated by a proportional magnet (16). After release of the control valve, its seat valve body (23) is mechanically taken along by the longitudinal gate valve (45), and both flows are proprotionally controlled by means of the lowering part (11) and the raising part (12), so that in a construction with little leakage, a high degree of switching control is achieved.

摘要： A hydraulic steering arrangement for vehicles is proposed, with a steering motor (5), a flow amplifier (4) in fluid connection therewith, which amplifies a fluid flow measured by a steering measuring device (1), at least one sensor (10, 11, 13), which determines a performance characteristic of the vehicle, and a control device (9), which changes the amount of fluid supplied to the steering motor in dependence on an output signal of the sensor.

For that purpose, the control device (9) changes the amplification factor of the flow amplifier (4).

摘要： A hydraulic steering mechanism of a vehicle comprises a hydraulic distributor (1) connected kinematically and hydraulically to a feed-back hydraulic machine (2). The feed-back hydraulic machine (2) comprises, evenly spaced along a circumference, peripheral gears (16, 17, 18), each being mounted on its axle and kinematically connected to a driving gear wheel (9). The system for supplying the working liquid comprises pairs of openings provided in each cover of each peripheral gear (16, 17, 18). First openings are hydraulically connected to each other and to a first hydraulic line (21) through grooves (27) in the corresponding covers. Second openings are hydraulically connected, through radial grooves (30) in each cover, to an annular cavity (31) which is formed by a central opening (32) in the driving gear wheel (9) and by a driving shaft (8) mounted inside it with an annular gap, and which is connected to a second hydraulic line (22).
