Technical field
The utility model relates to vehicle turbine boost electromagnetic valve technical field more particularly to a kind of novel supercharger electromagnetism
Relief valve.
Background technique
Currently, turbocharging technology, due to that can effectively improve engine efficiency, increasingly by the pro-gaze of people, it is
As one of gasoline energy epoch energy-saving and environment-friendly main trend.In addition, since the engine with supercharger with air throttle is accelerating
It will form an approximate closed volume after pedal unclamps suddenly, between compressor and air throttle, easily cause turbocharger
Surge.Therefore with the development of turbocharging technology, booster is also widely used with pressure release electromagnetic valve, it can be
Quick pressure releasing is realized when release the gas pedal under ECU control, prevents turbocharger surge.However, just because of relief valve will be realized
Quick pressure releasing, therefore the impulse stroke of relief valve is longer, generally in (5.0~6.0) mm, for current electromagnetic relief valve,
There are still following problems:
1. in existing relief valve with lip-shaped ring sealing seal periphery be cylindrical surface or circular conical surface, make relief valve or
Because column sealed face makes the whole process dynamic iron core of work by the resistance of motion, starting voltage and response speed are greatly increased,
Make electromagnetism defective valve in the case that automobile engine battery voltage range is certain, pressure release speed is slow, working efficiency is low；Because of cone
Lip-shaped ring is because spring-force driven dual is always in a state of stress when face makes nature, and epipharynx size becomes larger, when relief valve is true
Just being mounted on when working on engine can not seal, and pumping rate is slow when engine needs to be pressurized or can not be pressurized.
2. dynamic iron core is mostly used with the connection of seal and is fixedly connected in existing relief valve, mobile when due to dynamic iron core work
Distance, therefore the concentricity between seal, dynamic iron core, guide rod these three parts is required quite high, connected using fixed
If concentricity when connecing between seal and armature is bad, it is easy to stuck phenomenon occur, make pressure release defective valve, booster hair
Raw surge, or even additional noise can be caused.
