The air valve, the air valve guide rod, the armature, the electromagnet, the coil and the spring are arranged in the air cylinder cover. The air valve, the air valve guide rod and the armature are connected in sequence. The electromagnet is arranged below the armature. The coil is nested in the electromagnet. The spring is arranged between the armature and the air cylinder cover. The armature moves up and down in the air cylinder cover under the effect of the electromagnet. When the armature moves up, the upper end of the armature and the air cylinder cover form a first air chamber. When the armature moves down, the lower end of the armature and the air cylinder cover form a second air chamber. According to the diesel engine air spring solenoid drive air valve mechanism, a one-way valve and an adjustable throttle valve are used for closing and opening of the air valve in a matching mode, the adjustable throttle valve controls air flow to achieve soft landing of the air valve during falling back, and the diesel engine air spring solenoid drive air valve mechanism is convenient to use and easy to implement. The air spring provides reset force for closing of the air valve, consumption of the spring can be lowered, and economy and convenience are achieved.
Description
Technical field
The utility model relates to 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 purpose of this utility model 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 purpose of this utility model is achieved in that
The utility model diesel air air spring Electromagnetic Drive valve mechanism, 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 utility model 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 utility model is: the utility model 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 the utility model valve-closing.
Embodiment
For example the utility model is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～2, the utility model comprises: 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 10 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 utility model, 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 6.Active force lower armature 4 at pneumatic spring and spring 8 after coil 6 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.
