Abstract

The utility model relates to a carbon pot electromagnet valve. A skeleton winding an electromagnetic coil is arranged in a casing which is provided with a clamping groove, a fixed iron core and a movable iron core with an airproof cushion are arranged in an axle hole of the skeleton. The movable iron core and a matching hole of the skeleton are assembled through a clearance, a replacement spring is sheathed on the movable iron core, one end of the replacement spring gores the skeleton, and the other end gores the airproof cushion. A steel yoke is wound on the outer part of the electromagnetic coil, and insulation mediums are filled in clearances among the casing, the electromagnetic coil, the skeleton and the steel yoke. The utility model has the advantages that the utility model can carry out control and application to the flow of gasoline steaming in a carbon pot under the action of a vehicle electronic controller.

Description

Valve EGR

Affiliated technical field

The utility model relates to a kind of Valve EGR, is particularly useful for controlling the fuel steam discharge system.

Background technique

State Intellectual Property Office is at the tank body internal upper part one two-way and one-way valve to be housed in the gasoline car fuel evaporation control canister utility model patent of bulletin on August 28th, 1996, and the control gas port is arranged at the bottom, and there is a hanger that is used to install in the tank body outside.Yet the canister valve that this patent relates to can not be controlled utilization to the fuel-steam that is stored in the canister.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provide a kind of volume little, install conveniently, can utilize the different duty pulse signal, the gasoline vapor in the canister is controlled the Valve EGR of utilization.

The technical solution adopted in the utility model is: in the shell that draw-in groove is installed is arranged, the skeleton that a coiling electromagnetic coil is arranged, a 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, and Returnning spring one end withstands on the skeleton, and an end withstands on the sealing gasket, at electromagnetic coil outer most surrounding iron yoke, fill insulating medium in the space between shell and electromagnetic coil, skeleton, iron yoke.

Advantage of the present utility model is: simple in structure, install convenient, use reliable, under the automobile electronic controller effect, different operating modes according to motor, give the pulse signal of Valve EGR different duty, reach flow control, adapt to the needs of engine operating condition the gasoline vapor in the canister.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a profile schematic representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

By Fig. 1-Fig. 2 as seen, in the shell that installation draw-in groove (13) are arranged (1), the skeleton (10) that a coiling electromagnetic coil (2) is arranged, a secured core (9) and the movable core (8) that sealing gasket (6) are arranged are arranged in the axis hole of skeleton (10), movable core (8) is the gap assembling with skeleton (10) matching hole, Returnning spring (7) is enclosed within on the movable core (8), Returnning spring (7) one ends withstand on the skeleton (10), one end withstands on the sealing gasket (6), at electromagnetic coil (2) outer most surrounding iron yoke (3).Fill insulating medium (11) in the space between shell (1) and electromagnetic coil (2), skeleton (10), iron yoke (3).

Described Valve EGR also has a suction port (4) and an air outlet (5), and is provided with signal socket (12) on its shell.

The utility model Valve EGR is to realize opening and closing action by electrical pulse.When electrical pulse is arranged, secured core (9) has produced electromagnetic attraction, movable core under the electromagnetic attraction effect (8) drives sealing gasket (6) and moves to the direction that deviates from air outlet (5), Valve EGR is opened, when electrical pulse disappears, because the tension force effect sealing gasket (6) of Returnning spring (7) moves on the interior edge face that is blocked in air outlet (5) to air outlet (5) direction, Valve EGR is closed.

Claims

1. Valve EGR, form by frame, it is characterized in that: in the shell that installation draw-in groove (13) are arranged (1), the skeleton (10) that a coiling electromagnetic coil (2) is arranged, a secured core (9) and the movable core (8) that sealing gasket (6) are arranged are arranged in the axis hole of skeleton (10), movable core (8) is the gap assembling with skeleton (10) matching hole, Returnning spring (7) is enclosed within on the movable core (8), Returnning spring (7) one ends withstand on the skeleton (10), one end withstands on the sealing gasket (6), at electromagnetic coil (2) outer most surrounding iron yoke (3), at shell (1) and electromagnetic coil (2), skeleton (10) is filled insulating medium (11) in the space between the iron yoke (3).

2. according to the described Valve EGR of claim 1, it is characterized in that: a suction port (4) and an air outlet (5) are arranged on the shell (1), and be provided with signal socket (12).
