摘要： A hydraulic pilot valve consisting of a pair of pressure-reducing valves, wherein a stopper which can freely adjust maximum control inputs of operating levers of the hydraulic pilot valve is provided to make maximum pilot pressures output from the pair of pressure-reducing valves freely adjustable. Furthermore, in the hydraulic pilot valve, a stopper member for regulating a maximum control input of an operating lever is fixed to an operating lever, so that an operating force during a maximum operation of an operating lever is received by a member fixed to the operating lever. Furthermore, in the hydraulic pilot valve, an erroneous operation due to vibrations and the like are prevented by a damper mechanism interposed between a lever and a main body of the valve and fixed to an operating lever. Furthermore, a shuttle valve interposed between the output ports of the pressure-reducing valves can simplify the construction of the hydraulic pilot valve for taking out a maximum pilot pressure out of the pilot pressures of the output ports.

摘要： A load responsive system is provided with two synchronizing systems for positive and negative load compensation. One of the synchronizing systems varies the flow through a negative load compensator, during control of a negative load, in response to the inlet pressure of a fluid motor (10) which is controlled by a positive load compensator (51). The other synchronizing system isolates the system pump (12) from the fluid motor (10) during control of the negative load while make-up flow to the fluid motor (10) is supplied from the fluid exhaust system (11a). In a more specific arrangement, the system pump (12) is isolated from the fluid motor (10) through the use of the positive load compensator (51) and totally independant of any negative load compensating action. The synchronizing systems function in response to an external signal(s), which can be a function of any selected specific parameter of the system (SW, S2, S3, S4, S5).

摘要： A compensated direction-flow control valve assembly for control of fluid flow to and from a fluid motor, which may be of a cylinder type and is subjected to positive and negative loads. During control of negative load, the negative load compensating control (46) varies the level of the pressure differential across a metering orifice (37, 38), positioned at the outlet of the fluid motor (11), in response to pressure at the inlet of the fluid motor, while maintaining this pressure differential constant at each specific level. The pressure differential across a metering orifice (35, 36), positioned at the inlet of the fluid motor (11), is maintained at a constant preselected level by the positive load compensator control assembly.

摘要： A compensated direction-flow control valve arrangement provided with a direction control spool (19) for control of fluid flow to and from a fluid motor (11), which may be of a cylinder type and is subjected to positive and negative loads. During control of negative load the upstream of the outflow metering orifice (110), positioned at the outlet of the fluid motor (11), is maintained at a controlled constant pressure level by a pressure reducing valve (47) handling the fluid flow at negative load pressure. The outflow metering orifice (110) is made independent of the direction control spool (19) and its effective flow area is made responsive and varies with the pressure at the inlet of the fluid motor (11). The pressure differential across a metering orifice (35/36), positioned at the inlet of the fluid motor, is maintained at a constant preselected level by the positive load compensator (12).

摘要： Described is a power-assisted steering system, intended for motor vehicles, in which a pinion (2) mounted in the steering-gear housing (1) engages with a toothed rack (6). A steering valve (8) designed to control the hydraulic fluid used in the power-assisted steering system has two inlet seat valves (10, 11) and two outlet seat valves (12, 13) whose obturator elements are moved by actuator rods as a function of the rotary motion of a spindle. When the steering valve is in the neutral position, the outlet valves (12, 13) are open. The inlet valves (10, 11) are acted on by compression springs in the valve-closure direction and are not opened until after the associated outlet valve (12, 13) closes. Fitted on each side of the steering valve (8) is a limiting piston (31). Each piston (31) is acted on by one of the centering springs (30) and by a first pressure in the swept space of a servo motor on one side and by a limiting force on the other side. When the steering valve (8) is in the neutral position, the limiting force is greater than the force exerted by the centering spring (30) so that the limiting piston (31) rests against a stop shoulder when the steering valve (8) is in the neutral position. A design of this kind makes it possible to cut off or limit the actuation torque.

摘要： A hydraulic pilot valve designed so as to control the discharge rate of a pilot pressure oil at a constant level accurately in accordance with the stroke of an operating lever irrespective of the operating speed of the operating lever, and used to supply a pilot pressure oil by a pilot-operated change-over valve adapted to be switched by a pilot pressure oil. This hydraulic pilot valve has a valve spool (23) which can be slidingly moved between a first position, in which a pilot pressure oil from a pilot pressure oil supply pump (27 is discharged to an outlet port (26) formed in a valve body (1), and a second position, in which the outlet port communicates with a drainage tank port (30), and the operating power of an operating lever (38) for slidingly moving this valve spool (23) is transmitted to the valve spool (23) by utilizing the damping effect.
