摘要： Disclosed is an energy-recycling hydraulic control main valve, which is provided with end covers, a valve core, a left one-way valve and a right one-way valve, ; the left one-way valve is composed of a left valve seat, a left cone valve core and a left spring; a conical surface of the left cone valve core is closely attached to a left conical surface of the valve core by the spring force; the right one-way valve is composed of a right valve seat, a right cone valve core and a right spring; and a conical surface of the right cone valve core is closely attached to a right conical surface of the valve core by spring force. The hydraulic main control valve can not only limit the falling speed of a piston, but use the potential energy generated by the gravity action on the piston, thereby achieving energy recycling.

摘要： A control valve includes a signal pressure passage that transmits a pilot pressure of first and second pilot chambers as a signal pressure of another device, a connecting groove that is formed in a spool and connects the first pilot chamber to the signal pressure passage when the spool is in a neutral position, a connecting hole that is formed in the spool and connects the second pilot chamber to the signal pressure passage, and a check valve that is interposed in the connecting hole and permits a flow only from the second pilot chamber to the signal pressure passage. The connecting groove connects the first pilot chamber to the signal pressure passage when the pilot pressure is led into the first pilot chamber, and blocks communication between the first pilot chamber and the signal pressure passage when the pilot pressure is led into the second pilot chamber.

摘要： A pressure control valve for heavy equipment is disclosed, which can smoothly operate a working device having a high load pressure by limiting a supply of hydraulic fluid to a working device having a low load pressure in the case of simultaneously operating a plurality of working devices in a hydraulic circuit in which a plurality of control valves (e.g., a boom control valve and a bucket control valve) are connected in parallel to a single hydraulic pump. The pressure control device includes a valve body (5), a spool (13) slidably installed in the valve body and shifted to connect an input port (1) to an output port (2) or to disconnect the input port from the output port, and a signal pressure port (4) for applying a signal pressure to a diaphragm (D2) of the spool located in a third back chamber (14) formed in the valve body, disconnecting the input port (1) from the output port (2), and returning the pressure in the output port (2) to the drain port (3). The spool (13) is shifted, corresponding to the signal pressure applied from an outside to the third back chamber (14), to control the operating pressure being applied from the input port (1) to the output port (2).

摘要： A valve includes a valve body including a main passage defining a first volume and a second volume. The valve also includes a valve spool moveable relative to the valve body. The valve spool includes a central vent passage capable of fluid communication with each of the first volume and the second volume. Air flows between the first volume and the second volume through the central vent passage as the valve spool moves relative to the valve body and as the valve changes between an actuated position and a non-actuated position.
