摘要： The present invention relates to a device for damping undesirable oscillations of a crane member (1) which is pivotally movable by means of at least one hydraulic motor (5, 5'). The hydraulic circuit (8) has a restriction (13) co-operating with a circuit-closing device (14; 18) the purpose of the restriction being to convert energy inherent in the system to heat in the hydraulic oil. The device includes means (14, 15, 16, 16') for controlling the closing device (14; 18) according to instantaneous conditions and/or changes or conditions, such as pressure and/or flow, in the hydraulic circuit (8). The energy-converting action of the restriction (13) is instantaneously activated as soon as a certain condition and/or a certain change of condition occurs. The conduit (12) in which the restriction (13) lies is completely shut off, rendering flow of oil through the restriction impossible, as long as the energy-converting action of the restriction is not called for.

摘要： In einer hydraulischen Steuervorrichtung (S) mit einem doppelt wirkenden Hydroverbraucher (V), der über zwei Arbeitsleitungen (4, 5) druckbeaufschlagbar und in zumindest einer Arbeitsrichtung durch ein hydraulisch auf- und zusteuerbares Lasthalteventil (H) abgesichert ist, mit einer an einem Steueranschluß des Lasthalteventils angeschlossenen, wahlweise beaufschlagbaren Steuerdruckleitung (12), und mit einer Dämpfdrossel (13) in der Steuerdruckleitung (12), ist ein bei der Zusteuerbewegung des Lasthalteventils (H, 6) auf eine durch die momentane Viskosität des Druckmittels und/oder eine zu stramme Einstellung der Dämpfdrossel (13) bedingte und bezüglich des Nachlaufs des Hydroverbrauchers (V) unter einer Last (F) kritische Verzögerung der Zusteuerbewegung selbsttätig ansprechendes und dann auf Durchgang steuerndes, die Dämpfdrossel (13) umgehendes Ventil (15, 15', 15'', 15''', 15 IV ) vorgesehen. Das Ventil verhindert den Einfluß zu kalten Druckmittels und/oder einer für eine gewollte Dämpfung im Hinblick auf das Zusteuern des Lasthalteventils zu strammen Einstellung der Dämpfdrossel und gewährleistet das zum Anhalten und Haltern der Last notwendige rasche Zusteuern des Lasthalteventils, insbesondere bei einer Sicherheitsabschaltung.

摘要： A hydraulic system (600) and method for reducing boom dynamics of a boom (30), while providing counter-balance valve protection, includes a hydraulic actuator (110), first and second counter-balance valves (300, 400), first and second independent control valves (700, 800), and first and second blocking valves (350, 450). The actuator includes first and second corresponding chambers. In a first mode, the second counter-balance valve is opened by the first control valve, and the first counter-balance valve is opened by the second control valve. In a second mode, at least one of the counter-balance valves is closed. A meter-out control valve (800, 700) may be operated in a flow control mode, and/or a meter-in control valve (700, 800) may be operated in a pressure control mode. Boom dynamics reduction may occur while the boom is in motion (e.g., about a worksite). By opening the counter-balance valves, sensors at the control valves may be used to characterize external loads. The control valves may respond to the external loads and at least partially cancel unwanted boom dynamics. The system may further detecting faults in actuators with counter-balance valves and prevent any single point fault from causing a boom falling event and/or mitigate such faults.

摘要： A hydraulic system (600) and method for reducing boom dynamics of a boom (30), while providing counter-balance valve protection, includes a hydraulic cylinder (110), first and second counter-balance valves (300, 400), first and second control valves (700, 800), and a selection valve set (850). The selection valve set is adapted to self-configure to a first configuration and to a second configuration when a net load (90) is supported by a first chamber (116, 118) and a second chamber (118, 116) of the hydraulic cylinder, respectively. When the selection valve set is enabled in the first and second configurations, the second and first control valve may fluctuate hydraulic fluid flow to the second and first chamber, respectively, to produce a vibratory response (950) that counters environmental vibrations (960) of the boom. When the selection valve set is not enabled, the first and second counter-balance valves are adapted to provide the hydraulic cylinder with conventional counter-balance valve protection.

The method may include measuring first pressure ripples at the second chamber and reducing a magnitude of second pressure ripples at the first chamber. The pressure ripples may be transformed into a flow command by multiplying the pressure ripples by a gain and/or phase shifting. The gain and/or the phase shifting may be adjusted by feedback. The feedback may include the second pressure ripples at the load holding chamber, a position of the hydraulic actuator, and/or an operator input. A reference signal may be filtered with a moving average filter.

摘要： A digital valve positioner for use with an actuator. The digital valve positioner includes a housing, at least one exhaust port opening formed in the housing, and a vent assembly operatively coupled to the at least one exhaust port opening. The vent assembly includes a body having a bore, a valve seat surrounding the bore, and a check valve disposed within the bore. The check valve is arranged to shift from a closed position seated against the valve seat to an open position disposed away from the valve seat. A plurality of barriers is disposed around and positioned to enclose the check valve. The plurality of barriers is arranged to prevent an external medium from entering the check valve and to provide a tortuous flow path for the exhaust medium reducing sound through the vent assembly.
