ABSTRACT:
An engine is disclosed having at least one piston in operative connection with a crankshaft. A bearing member which defines an elongated, curved bearing surface, is pivotally attached at one end to an eccentrically-mounted member on the crankshaft. The bearing surface of the bearing member is positioned to be intermittently in power-transmitting, sliding relationship with a connection to the piston such as a piston rod. The bearing member is adapted to be rotatable about said pivotal attachment, for transverse displacement by the piston rod relative to the crankshaft, to absorb any shock generated against the piston and the crankshaft, such as by "engine knock." The bearing member is also adapted to return to its pre-displacement position after absorbing the shock.
