Patent ID: 8656872

Claim:
A variable lift hydraulic valve train, further comprising: a variable camshaft that upon rotation adjusts the location of a stroke limiter piston that is in fluid communication with a hydraulically operated valve; wherein the variable camshaft rotates independent of an engine RPM, and adjusts the location of the stroke limiter piston to thereby adjust the lift of the hydraulically operated valve; wherein a top housing supports the variable camshaft; wherein the top housing is mounted atop a bottom housing, which includes the hydraulically operated valve; wherein the hydraulically operated valve further comprises a master piston that moves up and down in mechanical connection with a camshaft; wherein a master piston cylinder contains hydraulic fluid that is in fluid communication with a stroke limiter cylinder containing the stroke limiter piston; wherein a channel is in fluid communication between the master piston cylinder and a valve piston cylinder containing a valve piston; wherein the valve is driven up and down via the valve piston and a spring.
