Abstract
The utility model discloses an engine valve revolution mechanic, including servo motor, pivot, advance/arrange passageway, valve, sealing washer, return spring, valve hole, support frame. The servo motor drives the rotating shaft to rotate the air valve to form an included angle with the air valve hole, and the air flow enters/exits the air cylinder in an air valve opening state; the servo motor stops driving the rotating shaft, the rotary valve returns under the return spring, and the rotary valve is in a valve closing state, so that airflow can not enter/exit the air cylinder. The utility model cancels the components such as camshaft, rocker arm, collar post and the like in the traditional valve actuating mechanism, simplifies the engine structure, saves space and weight; the problem that the seat ring is easy to wear due to impact of the closing of the traditional valve is solved, and noise is reduced; can realize automatic intelligent control, improve the dynamic property and the fuel economy of the engine and reduce the emission.
Description
Technical Field
The utility model belongs to the technical field of the engine technique and specifically relates to an engine valve revolution mechanic.
Background
At present, an engine drives a valve and a seat ring to move relatively by electromagnetism, electro-hydraulic, electric or a camshaft, so that air flow enters and exits an air cylinder. According to the valve motion in the mode, when the valve is closed and is seated on the seat ring, the valve and the seat ring are abraded due to overlarge seating impact force, so that the tightness of the valve and the seat ring is poor, and the combustion of mixed oil gas in the cylinder is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the valve and take a seat and lead to the wearing and tearing problem among the prior art, the utility model provides an engine valve revolution mechanic, the valve is under servo motor and return spring effect for the valve is opened and is closed.
The utility model provides a technical scheme that its technical problem adopted is: an engine valve rotating structure comprises a servo motor, a rotating shaft, an inlet/outlet channel, a valve, a sealing ring, a return spring, a valve hole and a supporting frame. The servo motor drives the rotating shaft to rotate the air valve to form an included angle with the air valve hole, and the air flow enters/exits the air cylinder in an air valve opening state; the servo motor stops driving the rotating shaft, the rotary valve returns under the return spring, and the rotary valve is in a valve closing state, so that airflow can not enter/exit the air cylinder.
The air valve is a small circular sheet, is integrated with the rotating shaft and is arranged on the air cylinder cover, an air valve hole matched with the air valve is arranged on the air cylinder cover, and the air inlet/outlet channel is arranged in the air cylinder cover and extends to the air valve hole.
The cylinder cover is provided with a support frame and a servo motor, and a motor shaft of the servo motor is connected with the rotating shaft.
And a sealing ring is arranged between the valve and the valve hole and is resistant to high temperature and high pressure.
The utility model discloses following beneficial effect has:
1. the utility model discloses a valve rotating mechanism has cancelled spare parts such as camshaft, rocking arm, collar post among the traditional valve mechanism, has simplified the engine structure, has saved space and weight.
2. The utility model provides a traditional valve close to the impact of seat circle and the easy wearing and tearing problem that causes, reduced the noise.
3. The utility model discloses in through servo motor drive valve, can realize automatic intelligent control, have the significance in aspects such as engine dynamic nature, fuel economy, reduction emission, the valve is opened closed constantly control accuracy height, nimble control valve opening angle.
