  • Connecting rod for changing a compression ratio of an internal combustion engine
    Patent number: 11635019
    Abstract: A connecting rod for changing a compression ratio of an internal combustion engine includes a connecting rod head, a connecting rod pin, and an interlock. The connecting rod pin is supported by an eccentric of the connecting rod at a variable distance within the connecting rod head. The connecting rod head or the connecting rod pin includes a fluid chamber and the eccentric has a projection extending into the fluid chamber. In the alternative, the eccentric delimits a fluid chamber and the connecting rod head or the eccentric has a projection extending into in the fluid chamber. A fluid pressure in the fluid chamber exerts a force on the projection to change the position of the eccentric. In a locking position, the interlock inhibits rotation of the eccentric relative to the connecting rod head and the interlock is configured to be releasable.
