Internal combustion engine camshaft phase shift control system
This patent describes an internal combustion engine, a rotary coupling for varying the timing of at least one camshaft relative to a crankshaft, the rotary coupling. It comprises a drive flange adapted to be coupled to the crankshaft for rotation about an axis; a driven flange adapted to be coupled to the at least one camshaft for rotation about the axis; a hydraulic coupling including a housing means connected to one of the flanges and a piston means cooperating with the housing means and connected to the other of the flanges, valve means for regulating the flow of fluid in the conduit means in response to a control signal; each the shuttle plunger member storing a predetermined volume of fluid under pressure to be selectively transferred to a respective one of the fluid chambers in response to a control signal; and control valve means within the conduit means.
