  • Patent number: 7628174
    Abstract: A hydraulic control arrangement is disclosed for the load-independent control of a consumer with a continuously adjustable distribution valve having a pressure compensator down the line. According to the invention, the pressure compensator has a single-sided damping such that the movement in the opening direction is damped and the movement in the closing direction is substantially undamped. Furthermore, a control arrangement is disclosed in which a load-holding function is integrated in the pressure compensator.
    Type: Grant

  • Patent number: 7213501
    Abstract: A hydraulic control arrangement is disclosed for the load pressure independent control of a consumer, comprising a distribution valve forming an inlet metering orifice, a corresponding individual pressure compensator, a stop valve provided for each consumer connection which may be released by means of a pilot valve and an anti-cavitation valve by means of which pressure medium can be drawn from a reservoir to avoid cavitation. According to the invention, the distribution valve and the stop valves are arranged along two parallel axes, while the axes of the two pilot valves are arranged perpendicularly to these two axes. The anti-cavitation valves in turn extend perpendicularly to the axes of the distribution valves, the stop valves and the anti-cavitation valves.

  • Patent number: 7080663
    Abstract: A valve assembly for load pressure-independent control of consumers is disclosed, which includes a main valve having a directional element and a metering throttle part. The valve assembly includes a shut-off valve for leakage-free shutting off of a work line leading to the consumer. This shut-off valve is designed with a pilot valve whereby a pressure chamber of the shut-off valve acting in the closing direction may be relieved towards a tank or a low-pressure source. The pilot valve is, in accordance with the invention, controlled open by a main slide of the main valve.
