Description
Affiliated technical field
The utility model relates to a kind of variable air inlet solenoid valve, is particularly useful for the engine air inlet tube variable technique of automobile.
Background technique
The engine air inlet tube variable technique has appearred recently, low speed torque and high speed output power to the raising motor are very effective, promptly with the rotating speed of motor and the length in changing load air inlet path, when making high rotating speed, gas-entered passageway shortens, and improves high-speed power, when making the slow-speed of revolution, gas-entered passageway is elongated, increases torque.Yet the intake manifold length of the motor of automobile is changeless at present, has influenced the power performance of automobile.
Summary of the invention
The purpose of this utility model is to overcome the immutable shortcoming of intake manifold length of present motor, and the variable air inlet solenoid valve that a kind of volume is little, can realize the automobile engine intake tube variable technique is provided.
The technical solution adopted in the utility model is: the skeleton that the coiling electromagnetic coil is housed in housing, secured core and the inner movable spool of inlaying sealing gasket are housed in the center hole of skeleton, Returnning spring is contained between secured core and the movable spool, its end leans in the spring base hole of secured core, the other end leans in the spring base hole of movable spool, the outer cover of electromagnetic coil is equipped with iron yoke shell, directly upwards insert iron yoke sheet at skeleton, and overlap with iron yoke shell, one side of housing is provided with two interfaces, and opposite side is provided with an interface of cover fixed filter.
Advantage of the present utility model is: simple in structure, volume is little, use is reliable, easy for installation, the variable air inlet solenoid valve that can realize the automobile engine intake tube variable technique.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
By Fig. 1 and Fig. 2 as seen, the skeleton (8) of coiling electromagnetic coil (7) is housed in housing (6), the movable spool (4) that sealing gasket (2) is inlayed in secured core (15) and inside is housed in the center hole of skeleton (8), Returnning spring (5) is contained between secured core (15) and the movable spool (4), its end leans in the spring base hole of secured core (15), and the other end leans in the spring base hole of movable spool (4).The outer cover of electromagnetic coil (7) is equipped with iron yoke shell (12), upwards inserts iron yoke sheet (16) in skeleton (8) footpath, and overlaps with iron yoke shell (12).One side of housing (6) is provided with two interfaces (1), (3), and opposite side is provided with an interface (11) of cover fixed filter (9).
Described variable air inlet solenoid valve, its secured core (15) have a vent (14) that passes core center, on secured core (15) and skeleton (8) fitting surface groove (13) of inlaying O-ring seal are arranged.
Described variable air inlet solenoid valve has airspace (18) on its skeleton (8) and movable spool (4) fitting surface.
Described variable air inlet solenoid valve is provided with signal socket (10) and draw-in groove (17) is installed on its housing (6).
The connection relation of three interfaces (1) of the utility model variable air inlet solenoid valve, (3), (11) is controlled by electrical signal.When electrical signal was arranged, secured core (15) had produced electromagnetic attraction, and movable spool (4) moves to the direction that deviates from interface (1) under the electromagnetic attraction effect, connected interface (1) and interface (3), cut off the connection of interface (11) and interface (1), (3).When electrical signal disappeared, because the tension force effect of Returnning spring (5), movable spool (4) moved to the direction of interface (1) and is blocked on interface (1) interior edge face, cuts off the connection of interface (1) and interface (3), the connection of connection interface (3) and interface (11).Realized the variable technique of suction tude thus.
Claims (4)
