Abstract
The present invention relates to an actuator of an electronic governor having a mechanical return device, and more particularly, to an actuator of an electronic governor having a mechanical return device and, more particularly, And more particularly, to an actuator of an electronic governor having a mechanical return device for safely shutting off the fuel supply by the electromagnetic valve.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuator of an electronic governor having a mechanical return device and more particularly to an actuator of an electronic governor, To an actuator of an electronic governor having a mechanical return device which is capable of shutting off the fuel supplied to the engine by a mechanical mechanism for a stable stop of the engine when the engine is stopped.
The conventional mechanical governor generally includes a flywheel which is hinged to a camshaft and opens and closes in accordance with the centrifugal force of the camshaft, a governor sleeve which slides and receives the movement of the flywheel by a linear movement force, An idle spring which is brought into contact with the sleeve and which provides an elastic supporting force in a direction to unwind the fly weight, and a control rack connected to the governor sleeve and connected to the control rack for controlling the injection amount of the plunger pump, And a link mechanism for transmitting the force.
The governor configured as described above controls the fuel injection amount according to the load variation of the engine by using the principle that the flywheel is opened or closed by the centrifugal force that is changed while the camshaft is rotated by the rotational force transmitted from the crankshaft of the engine .
On the other hand, in the case of an electronic governor that controls an amount of fuel supplied to an engine by receiving an electronic signal with respect to the state of the engine, the amount of fuel is controlled using data collected by the ECU, .
However, if the power supplied to the electronic governor is suddenly shut off, the electronic governor can not shut off the fuel flowing into the engine, which may cause malfunction of the engine.
As a prior art related to this, there is a domestic registered patent No. 10-0268657 (an electronic burner of an electronically controlled fuel injection device, registered on July 14, 2000).
SUMMARY OF THE INVENTION It is an object of the present invention to provide an actuator of an electronic governor having a mechanical return device capable of shutting off the fuel supply using a mechanical mechanism even when sudden power supply is interrupted during operation of the electronic governor.
Another object of the present invention is to provide an electronic control device for an internal combustion engine in which an elastic member provided outside the Governor housing for operating the electronic governor to cut off fuel supply is provided with a shaft for adjusting the amount of fuel supplied to the engine, And an indicator for confirming that the fuel supply is cut off visually.
In order to solve the above problems,
The present invention relates to an electronic governor, comprising: a governor housing which forms a body of the electronic governor and is provided on a plate for installing the electronic governor; A movable bracket coupled to a distal end of a shaft extending outwardly from one side of the Governor housing, and a movable bracket coupled to the end of the shaft, And an elastic member connected to the movable bracket and the fixing bracket at both ends to elastically deform and resiliently rotate according to the rotation of the shaft.
An indicator protruding from an outer surface of the movable bracket; and a display unit displaying a scale corresponding to the amount of opening of the electronic governor near the indicator on the outer surface of the Governor housing.
The elastic member includes a rod connected to the fixed bracket by a hinge shaft, a cylinder connected to the movable bracket by a hinge shaft to insert a distal end of the rod, and an elastic spring provided inside the cylinder and elastically deformed by the rod. .
When the electronic governor is operated to supply fuel to the engine, the elastic member is compressively deformed in accordance with rotation of the shaft.
The elastic member elastically restores to rotate the shaft to an initial position when power supply to the electronic governor is interrupted.
According to the solution of the above problems,
The present invention has the effect of improving the operational stability and reliability of the engine because the electronic governor can shut off the fuel supply even if the power supply is suddenly interrupted during operation of the electronic governor.
When the electronic governor cuts off the fuel supply, the elastic member provided outside the Governor housing returns the shaft to the initial position to adjust the amount of fuel supplied to the engine, and the effect of visually confirming that the fuel supply is blocked have.

In the state of FIG. 2, when the power is cut off to the electronic governor, the fuel can be safely shut off even if there is no power supply.
This is because the power supply is interrupted and the
Accordingly, the
As described above, by using the actuator of the electronic governor provided with the mechanical return device according to the present invention, when the power is supplied and the fuel is supplied to or blocked from the engine, the power supply is abruptly cut off, It is possible to safely shut off the fuel by using the circular restoring force of the elastic spring.
It is also possible to visually confirm whether the fuel supply is safely shut off from the outside of the
