Title:
METHOD FOR OPERATING EXHAUST VALVE FOR INTERNAL COMBUSTION ENGINE AND ITS EXHAUST VALVE
Document Type and Number:
Japanese Patent JP3857081
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for accurately controlling exhaust valve, including control during operation.
SOLUTION: To control an exhaust valve, a spool 21 of a control valves displaced in a longitudinal direction so that a low pressure port 8 or a low pressure port 11 can be connected to a first pressure chamber 29 in an actuator, and an actuator piston can be displaced in the first pressure chamber. An exhaust valve spindle 4 is longitudinally proportionally displaced in a ratio of 1:1 based on displacement in a longitudinal displacement. The spindle can be positioned between a complete release position and a complete closed position and is moved substantially simultaneously with the spool 21 between the closed position and the release position of the exhaust valve.
