  • Length-adjustable piston rod with a control device that can be hydraulically actuated and a switching valve that can be electromagnetically actuated, a reciprocating piston engine and a vehicle
    Patent number: 11199130
    Abstract: The invention relates to a longitudinally adjustable connecting rod (7) for a reciprocating piston engine, in particular a reciprocating piston internal combustion engine, a reciprocating piston engine, and a vehicle comprising a reciprocating piston engine. The longitudinally adjustable connecting rod (7) comprises a longitudinal adjusting mechanism (8) for adjusting an effective length (L) of the connecting rod, a hydraulically actuated control device (12), switchable at least between two control modes, for controlling the longitudinal adjustment, and an electromagnetically actuated hydraulic switching valve (9) for hydraulically actuating the control device (12).

  • MIXER ASSEMBLY
    Publication number: 20110249528
    Abstract: A mixer assembly for generating and maintaining a motion within a volume of liquid, the mixer assembly including a motor, a drive shaft and a propeller connected to the drive shaft. When the propeller is in operation, it is driven by the motor and rotates about a propeller axis. The mixer assembly's motor comprises a stator and a hybrid type rotor. The hybrid rotor includes a rotor core comprising an annular radially outer section of asynchronous type and an annular radially inner section of synchronous type arranged radially inside the annular radially outer section.
