Abstract

See full text

The embodiments of the present disclosure provide a valve actuator for a specialized stationary two-piston hydraulic engine, including a specialized drive cam, an actuator, an oil drive line, and a control valve. A hydraulic linkage is maintained between a primary piston and a secondary piston when the control valve is open, and the oil drive line is drained through the control valve when the control valve is closed. In the present disclosure, by integrating the primary piston and the secondary piston in a specialized actuator, oil consumption is reduced, and with a design of the specialized drive cam, an optimized design of the valve actuator that operates independently of a positive valve mechanism is realized, thus reducing interference and influence of the valve actuator on an operation of the positive valve mechanism.
