摘要： A hydraulic circuit on a harvesting machine for controlling the movement of a knife sharpening arrangement. The circuit comprises a pressure source, a pressure sink, a multi port valve, a first hydraulic cylinder which moves a knife sharpening device and a second hydraulic cylinder which moves a flap of a housing in which the knife sharpening device is housed. Each cylinder is connected to a respective valve arrangement and each respective valve arrangement will conduct fluid when a predetermined fluid pressure is reached. Movement of the multiport valve moves the first or second hydraulic cylinder so that when one of said first or second cylinders reaches a maximum deflection, the pressure in said circuit is greater than the predetermined fluid pressure of the respective valve arrangement of the other of said first or second cylinders so that said other first or second cylinder moves.

摘要： An inexpensive engine assist device capable of performing stable energy regeneration from an accumulator and a working machine on which the engine assist device is mounted are provided. A variable capacity type main pump (7, 8) and a variable capacity type assist pump (16) having a motor function and a pump function are directly connected to an engine (6). A return pressure oil flowing out from a fluid pressure actuator (3a, 9) is temporarily accumulated by a sub-accumulator (18) and is supplied to an inlet of the assist pump (16), and the assist pump (16) pressurizes the return fluid pressure oil and supplies the return fluid pressure oil to a main accumulator (17). A controller calculates and controls an assist pump swash plate angle using an engine load torque, and assist starting torque or charge starting torque set by engine speed setting means, and introduces a pressure-accumulated fluid discharged from the main accumulator (17) to the inlet of the assist pump (16) or introduces a pressurized fluid discharged from an outlet of the assist pump (16) into the main accumulator (17).

摘要： A method for transforming pressures of a system operating with pressure medium to optimize the travel speeds and/or forces of tasks utilizing pressure, area and flow ratios, employing valve structures, in which method, transforming with pressure transformers the pressure of the actuators differ from system pressure. A device implementing the method includes valve structures and pressure transformers. In the method, pressure transformers are switched when going above or below a set limit value controlling valves of actuators which requires the transformation of travel speed or force. In the device, pressure transformers are arranged to be switched when going above or below a set limit value controlling the valves for the actuator which requires higher travel speed or force.

摘要： Disclosed is a hydraulic circuit for controlling booms of construction equipment, wherein working oil which is relieved from a large chamber of a boom cylinder passes through an orifice so as to prevent the boom from lowering if an overload is applied when the boom is not being operated. The hydraulic circuit for controlling booms of construction equipment includes: a boom cylinder which is connected to a hydraulic pump via a first path and a second path; a boom control valve which is mounted on the path between the hydraulic pump and the boom cylinder; a holding valve which is mounted between the boom control valve and the first path of the boom cylinder and prevents the natural lowering of a boom when the boom control valve is in a neutral position; a port relief valve which is mounted to the first path at the lower side of a holding poppet and relieves working oil when an overload is generated at the first path; and an orifice valve which is mounted at the lower side of the port relief valve, relieves the working oil which passes through the port relief valve when the boom control valve is neutral so as to relieve the working oil through an orifice, and discharges the working oil which passes through the port relief valve to a hydraulic tank at the time of conversion due to boom-up pilot signal pressure which is applied to the boom control valve.
