Description
Technical field
The utility model relates to Valve EGR, especially relates to a kind of Valve EGR that is subjected to vehicle electronic control unit and the common control of engine intake manifold degree of vacuum.
Background technique
At present; existing automobile canister solenoid valve is mounted in the gasoline boil-off gas of automobile and recycles in the control system; gasoline in the fuel tank easily evaporates; steam output raises with temperature and increases; in order to guarantee that gasoline vapour does not enter befouling environment in the atmosphere; people utilize active carbon good adsorption ability; making canister temporarily stores gasoline vapour; when treating engine operation; the electronic control unit of automobile sends different electrical pulsing signal according to the operating mode of motor; opening or closing of control Valve EGR burnt thereby the gasoline vapour in the canister is sent into cylinder by Valve EGR, and the protection environment has been saved fuel again.But existing automobile canister electromagnetic valve structure, just under the automobile electronic controller effect, single control, electromagnetic force size by coil bag in the control Valve EGR, control the aperture size of valve port, thereby gasoline vapour enters the flow of motor in the control canister, is difficult for reaching the optimum flow state under the Under Different Work Condition of Engine.
For example, China Patent No. is that the patent documentation of ZL02210729.0 discloses a kind of Valve EGR, it comprises housing and the skeleton of coiling electromagnetic coil is arranged in housing, one secured core and the movable core that sealing gasket is arranged are arranged in the axis hole of skeleton, movable core and skeleton matching hole are the gap assemblings, Returnning spring is enclosed within on the movable core, Returnning spring one end withstands on the skeleton, one end withstands on the sealing gasket, and also the signalization socket receives the pulse signal that control unit sends by the signal socket, come control coil to produce the electromagnetic force size, the power size of control action on movable core, and then the size of control valve port opening are come control flow rate.
The model utility content
The purpose of this utility model provides a kind of automobile canister solenoid valve that is subjected to vehicle electronic control unit and the common control of engine intake manifold degree of vacuum.Reach the optimum flow state that gasoline vapour under the Under Different Work Condition of Engine enters motor.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of automobile canister solenoid valve, be provided with the suction port and the air outlet that is connected engine intake manifold that connects canister in valve body one side, and suction port is communicated with the air outlet by the valve body air flue; In valve body, be provided with the coil bag, be provided with secured core and movable core at coil bag endoporus, be provided with stage clip and rubber pad between secured core and the movable core, an end of movable core is by sealing gasket and the driving fit mutually of valve body intake duct, and the valve body bottom is provided with the electric mortiser sheet of promising coil bag power taking; It is characterized in that: also be included in the valve gap that valve body is provided with by the air outlet channel upper end, described valve gap top is provided with the hole that communicates with atmosphere; Be provided with the diaphragm plate assembly that opens and closes air outlet channel between described valve gap and the valve body air outlet channel, a compression spring that is in compressive state is set between diaphragm plate assembly and the valve body air outlet channel.
In order to play better sealing and sound deadening shock absorption effect, described sealing gasket and rubber pad are the two ends that are fixed on the active iron core iron by the vulcanization of rubber.
In order to filter out impurity in the air,, be provided with the sponge filter in the chamber that between described valve gap and diaphragm plate assembly, forms to the solenoid valve protection.
Assembling for convenience, described valve gap is to be connected by the buckle that is arranged on the valve gap with valve body.
In order to reach better damping effect, the arranged outside of described valve body has block rubber.
The beneficial effects of the utility model: owing to set up the valve gap that valve body is provided with by the air outlet channel upper end, described valve gap top is provided with the hole that communicates with atmosphere; Be provided with the diaphragm plate assembly that opens and closes air outlet channel between described valve gap and the valve body air outlet channel, a valve member that is in this form of compression spring of compressive state is set between diaphragm plate assembly and the valve body air outlet channel.Make it control the gap length of diaphragm plate assembly and valve body air flue, thereby control the flow of gasoline vapour under the Under Different Work Condition of Engine more accurately by different degree of vacuum in the intake manifold of motor generation.This valve arrangement is simple, low cost of manufacture.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
