    • The present invention describes, generally, a method and system for controlling the dynamics of an actuatable load functioning or operable within a servo or servo-type system, wherein the dynamics of the load are controlled by way of a unique pressure control valve 10 configured to provide intrinsic pressure regulation. The pressure control valve 10, which may be referred to as a dynamic pressure regulator because of its capabilities, utilizes dual spools 40 and 50 that are physically independent of one another and freely supported in the valve body 12 to regulate the pressures acting within the overall system between the control or pilot pressure and the load or load pressure. The dual spools 40 and 50 of the pressure control valve 10, although physically independent of one another, function in cooperation with one another in an attempt to maintain a state of equilibrium in the system, namely to keep pressure acting on or within the actuator 220 (the load pressure), or the feedback force corresponding to the load pressure, the same as the control or pilot pressure. Moreover, pressure regulation and control is intrinsic to the pressure control valve 10 because of the configuration and function of the dual spools 49 and 50 and the mechanical feedback system acting on the spools 40 and 50, thus eliminating the need for electronically or mechanically user controlled systems.
    • 本发明总体上描述了一种用于控制在伺服或伺服型系统中起作用或可操作的可致动负载的动力学的方法和系统,其中负载的动力学通过独特的压力控制阀10来控制,压力控制阀10构造成 提供内在的压力调节。 压力控制阀10由于其能力而被称为动态压力调节器,利用彼此物理上独立并且自由地支撑在阀体12中的双线轴40和50,以调节作用在总体上的压力 系统控制或先导压力与负载或负载压力之间。 压力控制阀10的双线轴40和50虽然在物理上彼此独立,但彼此配合起作用,以保持系统中的平衡状态,即保持作用在致动器220上或其内的压力 (负载压力)或对应于负载压力的反馈力,与控制或先导压力相同。 此外,由于双线轴49和50以及作用在线轴40和50上的机械反馈系统的结构和功能,因此压力调节和控制是压力调节阀10所固有的,从而消除了对电子或机械用户控制的需要 系统。

    • An arrangement for supplying pilot oil to a servo-valve arranged to activate a main valve of a hydraulic system. The hydraulic system also includes a hydraulic oil pump, a valve located between the pump and the main valve, and a pressure reducing valve located between the pump and the servo-valve, and one or more auxiliary assemblies arranged to deliver an electric signal to electromagnetic means arranged to activate the servo-valve. In accordance with the invention, the valve (5) located between the pump (2) and the main valve (3) is arranged to be substantially or fully closed when standing at a given, pre-determined pressure corresponding to the servo pressure required by the servo-valve (4) in order to carry out its intended function, and is arranged to be open when the pressure slightly exceeds the aforementioned pre-determined pressure. According to a preferred embodiment of the invention, there is located between the pump (2) and the pressure reducing valve (6) electromagnetically operable shunt valve (38) which, when open, is arranged to pass oil direct from the pump (2) to a tank (7). The shunt valve (38) is arranged to take its closed position upon receipt of a signal delivered from the auxiliary assemblies (13-17) when one of these assemblies is activated so as in turn, to activate the servo-valve (4).
