摘要： A variable valve assembly, engine valve control system, and method of operation wherein the valve is hydraulically controlled and includes a valve piston subjected to fluid pressure acting on surfaces at both ends of the valve piston. The cavity at one end of the valve piston is connected to a source of high pressure fluid while the cavity at the other end is connected to a source of high pressure fluid and a source of low pressure fluid, and disconnected from each through action of controlling means such as solenoid valves. The valve assembly includes a damper to limit the velocity of the valve during a portion of the travel of the piston, particularly as the valve head lands on the valve seat.

摘要： A variable engine valve control system wherein each of the reciprocating intake and/or exhaust valves is hydraulically controlled and includes a piston subjected to fluid pressure acting on surfaces at both ends of the piston. The space at one end of the piston is connected to a source of high pressure fluid while the space at the other end is connected to a source of high pressure fluid and a source of low pressure fluid, and disconnected from each through action of controlling means such as solenoid valves. The controlling means may include a rotary hydraulic distributor coupled with each solenoid valve, thereby permitting each solenoid valve to control operation of a plurality of engine valves in succession. Equal air delivery to all engine cylinders having the aforementioned variable valve control system is assured by controlling electric pulses of variable duration and timing, the system involving means for making individual modifications of the durations of the electric pulses controlling each individual actuator, and the modifications being of such nature as to assure that all actuators control the engine intake (or exhaust) valves in an identical manner to assure equal valve strokes in all cylinders.
