Opening and closing of the valve are matched through a one-way valve and an adjustable throttle valve, and the adjustable throttle valve controls air flow to achieve soft landing when the valve falls back, so that the air spring electromagnetically-driving valve mechanism of the diesel engine is convenient and feasible; and the air spring supplies a resetting force for the closing of the valve, so that consumption of the spring can be reduced and the air spring electromagnetically-driving valve mechanism of the diesel engine is economical and convenient.
Description
Technical field
What the present invention relates to is a kind of motor, specifically the valve mechanism of motor.
Background technique
The distribution device of diesel engines at present adopts the mechanical device of the direct or indirect driving valve of cam more.In running, the impacts such as the mechanical wear of camshaft, gap, circular runout cause the valve impact noise; Valve timing is subjected to the impact of cam face and machining accuracy, is difficult to directly perceived the correction.Simultaneously, valve is slowly opened and is taken a seat, and causes the valve wide-open time short, and intake efficiency is low.And actuated by cams distribution device processed complex, technical requirements and cost are high.
Application number is: 201110101673.2, name is called in the patent document of " electric control air valve driving mechanism for automobile engine " and discloses a kind of electric control valve driving mechanism, by the switch of the control of the pressure difference between plunger intracavity liquid and return spring electro-hydraulic actuator, the switching that the pressure of plunger intracavity liquid changes by solenoid valve realizes.The moment that engine valve is opened is controlled constantly by the energising of high-speed electromagnetic valve, and the close moment of valve is by the power-cut time control by high-speed electromagnetic valve.Its shortcoming is: complex structure, be difficult for maintenance, and the break-make by changing solenoid valve and the pressure of liquid could be realized the switching of valve, the valve response time is long.In sum, its performance and reliability can not satisfy diesel engine to the requirement of valve mechanism.
Anti-air-stop gate falls excessive velocities after rise; the protective gear of impingement cylinder lid has had relevant research; such as Chinese patent application number be in 201010105591.0 the patent document; propose a kind of air valve seating control device for hydraulic drive air valve mechanism of engine, have the structures such as hydraulic piston, hydraulic pressure oil duct, one-way valve, hydraulic piston, variable restrictor passage.It is control media that this structure adopts hydraulic oil, and the cleaning cost of upkeep is high.Need the devices such as hydraulic pressure oil duct, hydraulic oil container, increased unnecessary load.
Summary of the invention
The object of the present invention is to provide valve to begin the diesel air air spring Electromagnetic Drive valve mechanism that Timing is convenient, can control valve crash speed.
The object of the present invention is achieved like this:
Diesel air air spring Electromagnetic Drive valve mechanism of the present invention, it is characterized in that: comprise cylinder head and be installed in valve in the cylinder head, valve guide rod, armature, electromagnet, coil, spring, valve, valve guide rod, armature links to each other successively, electromagnet is installed in the below of armature, coil is nested in the electromagnet, mounting spring between armature and the cylinder head, armature is done in cylinder head under the electromagnet effect and is moved up and down, when armature moves up, the upper end of armature and cylinder head form the first air chamber, when armature moved down, the lower end of armature and cylinder head formed the second air chamber.
The present invention can also comprise:
1, also comprise one-way valve, adjustable restrictive valve, one-way valve and adjustable restrictive valve are connected with the first air chamber.
Advantage of the present invention is: the present invention cooperates the switching of valve by one-way valve with adjustable restrictive valve, and the soft landing when adjustable restrictive valve control air mass flow realizes that valve falls after rise is convenient and easy.Pneumatic spring provides reposition force for valve-closing, can reduce the consumption of spring, and is economical convenient.

Structural representation when Fig. 2 is valve-closing of the present invention.
Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～2, the present invention includes: one-way valve 1, adjustable restrictive valve 2, air chamber (1) 3, armature 4, electromagnet 5, coil 6, air chamber (2) 7, spring 8, valve guide rod 9, valve 10, one-way valve 1, adjustable restrictive valve 2 are connected with air chamber (1) 3.Coil 6 is nested in the electromagnet 5, and the two places armature 4 belows.Coil 6, electromagnet 5, armature 4 form electromagnetic actuator.Electromagnetic actuator cooperates control valve 9 to open and close with spring 8.Spring 8 is arranged in air chamber (2), is connected with armature 4 bottoms.Valve guide rod 9 guarantees the straight line motion of valve 10.Valve 10 is connected with armature 4 by valve guide rod 9.
Diesel air air spring Electromagnetic Drive valve mechanism of the present invention, electromagnet 5 produces electromagnetic force after coil 6 energisings, attracts armature 4 to move downward after electromagnetic force is greater than initial tension of spring.At this moment air chamber (1) 3 is in sealing state, and air enters air chamber (1) 3 from one-way valve 1, prevents from forming in the air chamber (1) 3 negative pressure and hinders armature 4 declines.Armature 4 declines drive valve and open, and cylinder and air flue are open-minded, such as Fig. 1.Increase coil 6 electric current electromagnetic forces and increase, overcome more big spring elastic force, armature 4 bottoms were with air chamber (2) 7 sealings after electromagnet 5 attracted armature 4 to continue to descend.Air chamber (2) 7 interior air compressings form pneumatic spring, cooperate control valve 10 apertures with spring 8.Can freely control opening time and valve 10 lifts of valve 10 by the size of current in the control coil 4.Active force lower armature 4 at pneumatic spring and spring 8 after coil 4 outages moves up.Open when rising to certain displacement rear gas chamber (2) 7, air stream suction chamber (2) 7 is so that pneumatic spring is effective when valve 10 is opened next time.Behind armature 4 top seal air chambers (1) 3, air in the air chamber (1) 3 flows out from adjustable restrictive valve 2, regulate throttle valve 2 apertures control air flow rate, making has enough pressure-actings in armature 4 tops in the air chamber (1) 3, and anti-air-stop gate 10 falls excessive velocities impingement cylinder lid after rise.The rising of armature 4 drives valve 10 by valve guide rod 9 and closes, such as Fig. 2.
