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).

Abstract: A length-adjustable connecting rod for a reciprocating piston machine, which may be a reciprocating piston internal combustion engine, is disclosed as well as a reciprocating piston machine and a vehicle. The connecting rod comprises a hydraulic length-adjusting device for adjusting an effective connecting rod length and a control device that can switch between two switching states, for controlling the length-adjusting device. The length-adjusting device comprises a hydraulic cylinder with a piston and a first hydraulic working chamber and a second hydraulic working chamber, the control device comprising a first valve and a second valve, the first valve of the control device being connected to the first hydraulic working chamber of the length-adjusting device in a fluid-communicating manner, and the second valve to the second hydraulic working chamber, the first valve and the second valve each being actuatable by means of a hydraulically actuatable adjusting piston that can axially move along an adjusting axis, the adjusting axis of the first valve being different from the adjusting axis of the second valve.
