摘要： A valve assembly for regulating the pressure of a pressure medium (2) of a pressure medium pump (3) to at least one first consumer (4) includes a pilot-controlled pressure control valve (5) with a main piston (6) acted on by the pressure medium (2) and a pilot piston (7). A pressure chamber (8) between a piston back side (9) of the main piston (6) and the pilot piston (7) can be relieved. A relief valve (10) is connected in a fluid-conducting manner to the pressure chamber (8), opens when pressure at the load sensor (LS) represents an out-of-operation mode of the consumer (4), and recirculates pressure medium (2) having a low pressure to a pressure medium reservoir (11) or to the pressure medium pump (3). The relief valve (10) closes when the pressure at the load sensor (LS) represents an in-operation mode of the consumer (4).

摘要： A pressure controlling valve includes a slidable spool arranged to be spring loaded towards a neutral position. A first port and a second port are connected to allow a fluid flow through the valve. A first and a second pilot port are connected to a cavity adjacent a respective first and second end surface of the spool. The pilot ports are connected to a fluid conduit on either side of a fluid device causing a pressure drop in the fluid conduit and the fluid device is connected to one of the first or second ports. The spool is displaced against the spring load in response to a pressure difference between the first and the second pilot port, whereby a control surface of the spool is arranged to restrict the fluid flow through the valve when the control surface approaches a central cavity.

摘要： The invention concerns a hydraulic valve arrangement (1) with a supply connection arrangement comprising a high-pressure connection (P) and a low-pressure connection (T), a working connection arrangement comprising two working connections (A, B), which can be connected to a motor (4), a directional valve arrangement (5) located between the supply connection arrangement (P, T) and the working connection arrangement (A, B), and a compensation valve (15) acted upon in a first activation direction by a pressure in a first pressure chamber (33), which is connected to a load-sensing pipe (LS), and, if required, by a spring (32), and in a second activation direction opposite to the first activation direction by a pressure downstream of the directional valve arrangement (5), said pressure acting in a second pressure chamber (34), the compensation valve (15) having an inlet (14) and an outlet (19). In connection with a post-compensated valve, it is endeavored to adjust the load pressures at the working connections (A, B) in dependence of the direction. For this purpose, each working connection (A, B) is connected to a control system, which amplifies the effect of the pressure in the first pressure chamber (33) on the compensation valve (15) in dependence of a pressure ruling at the working connection (A, B).

摘要： A valve arrangement has an adjustable control valve (10) including a control slide (12) for actuating at least one consumer connection (A, B) and an LS control line. The differential pressure of two actuating pressures (xa, xb) serves for the actuation of the control slide (12). Since the actuating pressures (xa, xb) also actuate a logic valve, which in turn influences an additional valve, and/or actuates a pressure compensator connected upstream to the control valve (10), the difference of the two actuating pressures (xa, xb) initially displaces the control slide of the control valve. The higher or the lower of the two actuating pressures (xa, xb) either actuate the further valve in the form of the additional valve, and/or influences the pressure compensator.

摘要： A hydraulic control device of construction machinery having a main merging/diverging valve interposed in a connecting oil path connecting discharge oil paths of first and second hydraulic pumps in a merging position, operating levers for corresponding works operated to actuate plural actuators, an operating condition judging section judging a lever operating condition of each operation lever, a pattern collating section selecting an operating pattern matching an actual operation pattern from set and stored various operation patterns corresponding the operating conditions in a controller. When a load pressure of each actuator is high, a discharge pressure of each discharge oil path is also high, and when a total of the discharge pressures exceeds a predetermined set pressure, the main merging/diverging valve is switched to a diverging position, and when the total of the discharge pressures drops to below the set pressure, the main merging/diverging valve is switched to the merging position.
