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: The disclosed subject matter relates to a measuring device for measuring the flow velocity of a flowing fluid, comprising a first measuring element, which is configured to measure the flow velocity of the fluid and includes an interface that can be exposed to the flowing fluid, a second measuring element, which is configured to measure a characteristic property of the fluid and includes an interface that can be exposed to the flowing fluid, and an evaluation unit, which is connected to the first and second measuring elements and configured to correct the flow velocity, measured by the first measuring element, by the influence of the property of the fluid, measured by the second measuring element, on the measurement of the flow velocity. The disclosed subject matter furthermore relates to a measuring probe for such a measuring device.

Abstract: The invention relates to a length-adjustable connecting rod for a reciprocating piston engine, particularly a reciprocating piston internal combustion engine, comprising a hydraulic arrangement with which a length of the connecting rod can be adjusted, and a switching valve for controlling the inflow and outflow of a hydraulic medium into or out of the hydraulic arrangement, wherein the switching valve can be actuated electromagnetically.

Abstract: The invention relates to a reciprocating-piston machine, in particular an internal combustion engine, comprising at least one length-adjustable connecting rod (1) connected to a crank pin (21) of a crankshaft (26), wherein the connecting rod (1) comprises at least one length-adjustment mechanism (6) and at least one electrically switchable and inductively actuatable control valve (7).

Abstract: The invention relates to a reciprocating piston engine, in particular an internal combustion engine, comprising at least one length adjustable connecting rod (1) connected to a crankshaft (26), which connecting rod (1) comprises at least one first rod part (2) having a small connecting-rod eye (3) and at least one second rod part (4) having a large connecting-rod eye (5), which two rod parts (2, 4) can be displaced telescopically with respect to and/or into each other by means of a length adjustment device (100), wherein the length adjustment device (100) can be fluidically connected in at least one position of a control valve (15) to at least one oil pressure line (14, 6), and can be separated from the oil pressure line (16) in at least one second position of the control valve (15), wherein the control valve (15) can be electrically switched and inductively actuated.
