摘要： A pressure control valve for at least one of controlling and/or regulating a pressure level in a hydraulic circuit. The control valve comprises a valve housing (1) in which a control element (2), that can be acted upon by a system pressure (P_Sys), is arranged to move. The control element (2) is coupled to a drive mechanism in order to set an operating pressure (P_Kpl). At least one linear motor (3) is provided as the drive mechanism which can be controlled at least by a signal feedback (4) acting as a control circuit as a function of the operating pressure (P_Kpl) actually set at the time.

摘要： An electro-hydraulic control system for actuating a control valve includes a control module. The control module is coupled to the surface via at least one hydraulic line and two electrical power lines. The control module uses one of the hydraulic lines as a “supply” line and the other line as a “return” line if included. Each hydraulic line of the at least one hydraulic lines can be used as an “open” line or a “close” line to open or close the control valve. The control module includes two normally closed (NC) solenoid valves (SOVs) that are coupled to the electrical power lines and can be controlled from the surface to open or close. The opening or closing of the NC SOVs in cooperation with hydraulic pressure on a “supply” line of the hydraulic lines operates (i.e., closes or opens) the control valve.

摘要： An actuation pressure to actuate one or more hydraulic actuators may be determined based on a load on the one or more hydraulic actuators of a robotic device. Based on the determined actuation pressure, a pressure rail from among a set of pressure rails at respective pressures may be selected. One or more valves may connect the selected pressure rail to a metering valve. The hydraulic drive system may operate in a discrete mode in which the metering valve opens such that hydraulic fluid flows from the selected pressure rail through the metering valve to the one or more hydraulic actuators at approximately the supply pressure. Responsive to a control state of the robotic device, the hydraulic drive system may operate in a continuous mode in which the metering valve throttles the hydraulic fluid such that the supply pressure is reduced to the determined actuation pressure.

摘要： In a capacity control valve, a position of a valve element is changed by drawing a movable iron core to a fixed iron core with magnetic force by energization of an electromagnetic coil. The iron core on one side includes a projected portion on the radially outer side, the iron core on the other side includes a projected portion on the radially inner side, and these projected portions are capable of being loosely fitted to each other when the movable iron core is drawn to the fixed iron core. The projected portion is formed to be smaller than an opposing surface of the iron core facing an effective magnetic force surface of a distal end of the projected portion and formed in a tapered shape.
