    摘要： An axial piston machine having a swashplate design includes a cylinder drum that is rotatably supported in a housing and that has a plurality of cylinder bores, which have pistons that can be slid longitudinally in said cylinder bores and that are supported on a swashplate. The aim of the disclosure is to achieve an improvement in the efficiency with a short length design by means of reducing the lost forces. The aim is achieved in that no force components act on the pistons in the radial direction.

    摘要： A fluid-working machine has a plurality of working chambers, e.g. cylinders (11), of cyclically changing volume, a high-pressure fluid manifold (14) and a low-pressure fluid manifold (16), at least one valve (13, 15) linking each working chamber to each manifold, and electronic sequencing means (20) for operating said valves in timed relationship with the changing volume of each chamber (11), wherein the electronic sequencing means is arranged to operate the valves of each chamber in one of an idling mode, a partial mode in which only part of the usable volume of the chamber is used, and a full mode in which all of the usable volume of the chamber (11) is used, and the electronic sequencing means (20) is arranged to select the mode of each chamber on successive cycles so as to infinitely vary the time averaged effective flow rate of fluid through the machine.

    摘要： An automatic bidirectional valve includes: a valve body, a central conduit that crosses the valve body and is provided with a first opening in a first end of the valve body and a second opening made in an opposite second end thereof, and a peripheral conduit made in the valve body, provided with a first opening, made in a portion of the valve body between the first and second ends, and a second opening made in the second end. A first shutter is movable between a closing position and an opening position, a first elastic element configured to generate a force adapted to maintain the first shutter in the closing position, a second shutter movable between a closing position, and an opening position, a second elastic element configured to generate a force to maintain the second shutter in the closing position, and a retaining body fixed to the valve body.

    摘要： A pumping unit for a machine to distribute concrete includes a pair of cylinders provided with a relative pumping piston movable linearly for a determinate travel to feed the concrete to a determinate circuit to distribute the concrete; and a hydraulic command circuit operatively connected to both the cylinders, to determine an alternate pumping movement of the relative pumping pistons. The pumping unit includes at least a sensor member operatively associated to at least one of the cylinders in order to detect point-by-point one or more data relating to the operating condition of the pumping piston during its movement for the whole travel. The data includes at least one of position, speed, stress and direction of movement of the relative piston.
