Patent ID: 8656873

Claim:
An oil control valve assembly for an engine with an engine component, a cam phaser valve, and a valve lift switching component, comprising: a control valve having a manifold defining a control passage in fluid communication with the valve lift switching component and an exhaust passage for exhausting fluid from the control valve; wherein the control valve is controllable to selectively direct fluid from a feed passage in fluid communication with the supply source to the control passage to actuate the valve lift switching component; wherein the feed passage is in fluid communication with the cam phaser valve so that pressure in the feed passage varies; an elongated tubular member positioned adjacent the engine component and operatively connected to the exhaust passage such that fluid flows from the exhaust passage to the elongated tubular member and through the elongated tubular member onto the engine component; a pressure relief valve in fluid communication with the exhaust passage and configured to open when pressure in the exhaust passage reaches a predetermined pressure that is less than a minimum pressure required to actuate the valve lift switching component; and a pressure regulator valve configured to regulate fluid pressure provided to the supply passage and the bypass passage via the feed passage.
