This self-guided reciprocating support crossbar (1, 31) for pistons (2, 3, 4, 5, 32, 33, 38, 39, 46, 47, 48, 49, 63, 64, 65, 66), particularly for engines, compressors and pumps, is characterised by comprising means for generating variable central thrusts (36) for counteracting its inertial forces. |
