Abstract
A variable length connecting rod includes a connecting rod body, an eccentric member, a first piston mechanism, a second piston mechanism and a flow-direction switching mechanism. The eccentric member, the first piston member, the second piston member and the flow-direction switching mechanism are provided in the connecting rod body. The first piston mechanism and the second piston mechanism are configured to pivot the eccentric member. The connecting rod body has a control oil passage that communicates with a first opening of the connecting rod and the flow-direction switching mechanism. The flow-direction switching mechanism is switched between the first state and the second state by switching pins. The switching pins are disposed in the connecting rod body such that directions in which the switching pins are operated are angled with respect to a plane perpendicular to an axis of the first opening.
