Abstract
A variable compression ratio (VCR) phaser configured to control a compression ratio of an engine having a crankshaft and a control shaft. The variable compress ratio phaser comprises: i) a control shaft gear configured to mesh with a gear on the control shaft of the engine and to receive torque from the control shaft; ii) a crankshaft gear configured to mesh with a gear on the crankshaft of the engine and to deliver torque to the crankshaft; and iii) a torque conversion mechanism configured to receive torque from the control shaft and to convert the torque to a linear force that changes the compression ratio of the engine.
