    Abstract: Methods and systems for a variable displacement bent axis piston motor are described. In one example, a variable displacement bent axis piston motor comprises a bent axis unit (BAU) rotary group including a cylinder block coupled to a drive shaft of the bent axis piston motor, and an electric actuator coupled to a servo piston of the bent axis piston motor, wherein a displacement of the BAU rotary group is controlled by an inclination angle between the drive shaft and a valve plate of the BAU rotary group coupled to the cylinder block, the inclination angle controlled by the servo piston, the servo piston controlled by the electric actuator. The servo piston is controlled by the electric actuator based a feedback control system, which may switch between various control strategies for adjusting the inclination angle based on different driving scenarios.

    Abstract: A steering system for vehicles with independent axles is disclosed. The system may have a second circuit for control of a second cylinder. The second circuit may have a solenoid valve, with at least four ways and three positions. The solenoid valve may be interposed between a second hydraulic liquid inlet line, a second hydraulic liquid outlet line, and a third operating duct and a fourth operating duct for the passage of hydraulic liquid. The system moreover envisages an electronic unit for management and control of the directional-control solenoid valve, which is operatively connected to a device for detecting the steering angle imposed by the first cylinder and is designed to manage the directional-control solenoid valve as a function of the data detected by the device.

    Abstract: A valve assembly and a hydraulic circuit including the valve assembly are provided. The valve assembly comprises a hydraulically actuated valve configured to be biased from a first control position to a second control position by a hydraulic pressure applied to a first fluid port of the hydraulically actuated valve. A first switching threshold pressure required to switch the hydraulically actuated valve to its second control position when applied to the first fluid port of the hydraulically actuated valve in its first control position differs from a second switching threshold pressure required to keep the hydraulically actuated valve in its second control position when applied to the first fluid port of the hydraulically actuated valve in its second control position.

    Abstract: The present disclosure relates to an expansion plug assembly, comprising a body with a channel to be plugged, the channel being defined by a channel wall which has a circumferential groove, a diameter of the groove being larger than a diameter of the channel, and a bushing for inserting into the channel of the body. The bushing comprises an orifice with a partially surrounding bushing wall, the bushing wall having a first bushing wall section having at least a bendable fin for forming a form-fit connection with the circumferential groove, and a tapered pin configured to bend up the bendable fin when inserted into the orifice of the bushing such that the bendable fin forms the form-fit connection with the circumferential groove when the bushing is inserted into the channel.
