<p>The invention relates to a longitudinally adjustable connecting rod (1), in which a piston part (2) and a shaft part (9) are telescopically inserted one inside the other. Piston part and shaft part can be locked together at certain lengths by pins (5a, 5a', 5b, 5b') supported in the piston part skirt (8), which engage in associated recesses (4a, 4a', 4b, 4b') on the shaft part skirt (3). Every two pins (5a, 5a'; 5b, 5b') are pushed apart by springs (11a, 11b) situated between them. Through corresponding feed ducts (7a) a hydraulic medium can be purposely delivered to the recesses in the piston part skirt (3), in order to push pins situated therein back into the shaft part skirt (8).</p> |
