Description
Technical field
The present invention relates to a kind of electromagnetic valve with valve body; In said valve body, have one can with packing element osed top valve seat, part at least that at least one leads to electromagnetic valve hold packing element fluid cavity escape route and one at least part surround the diversion member of packing element; Said packing element effectively is connected with armature during armature chamber is set, and said armature chamber is built into a side of the fluid cavity dorsad of diversion member.The invention still further relates to a kind of driver assistance device.
Background technology
The electromagnetic valve of the above-mentioned type is that prior art is known.This type of electromagnetic valve does not for example have the stream two-position two-way solenoid valve of closing or does not have the two-position two-way solenoid valve that stream closes and can in ABS system, TCS system or ESP system, use.These electromagnetic valves all have can use packing element osed top valve seat.Packing element can move between off position and open position at least for this reason.Thereby packing element is arranged in off position makes it hide valve seat its sealing.In the open position packing element for example with valve seat separately, thereby make fluid can pass valve seat.Electromagnetic valve does not allow to pass through for fluid in off position, and fluid then can be crossed electromagnetic valve by percolation in the open position.With packing element at least part be arranged among the fluid cavity of electromagnet.Valve seat also can be positioned among the wall portion of fluid cavity.In addition, also have at least one escape route to lead to fluid cavity, wherein between fluid cavity and escape route, can exist lasting fluid to connect.Fluid is transferred to electromagnetic valve through access passage, and wherein fluid is drawn towards valve seat through access passage.When packing element was in the open position, fluid just can enter into fluid cavity via valve seat so, was derived through escape route then.
In the open position, packing element is disposed in the valve seat top usually, packing element or connected armature thereby the feasible fluid that flows through valve seat is also flowed through.In addition, the flow direction of the fluid of inflow deviates from escape route usually, thereby can before fluid flows into escape route, at first in fluid cavity, be slowed down.At this, fluid also can arrive the zone between armature and the electromagnetism valve housing.All can the mobility of packing element be impacted at circulation that causes around packing element and/or the armature and the fluid that gets between armature and the housing by the fluid that flows into because fluid can with add axial force be applied to packing element or with armature that packing element links to each other on.In some cases, this may cause adverse effect to the quality of regulation of electromagnetic valve.This causes by following situation, and promptly this subsidiary load can impact the force balance between the fluid pressure of being considered at the reset force of spring element with when acting on the magnetic force that is used for the hydrodynamic reciprocating sealing element on the armature and design electromagnetic valve.In electromagnetic valve, be such a case especially, promptly the aperture arrangement of escape route is disposed in by the valve seat in fluid cavity, thereby realizes inflow and realization fluid process escape route in the opposite direction the outflow of fluid through valve seat.
In principle advantageously, rotational symmetric diametral load only occurs and act on the subsidiary load on packing element or the armature vertically, because this can not influence axial force balance to substitute.In view of this reason, a kind of diversion member can be set, this diversion member for example has a guide face, can be so that the fluid that flows into makes fluid be drawn towards this escape route towards the directional steering of escape route in other words through this guide face.Said guide face part at least is crooked, and is advantageously crooked towards the direction of escape route.At this, said diversion member separates the armature chamber of electromagnetic valve with the fluid cavity that valve seat belongs to.Forming effective bonded assembly armature with packing element is disposed among the armature chamber.Through this effective connection, packing element can move by means of armature, and wherein this can carry out between off position and open position at least.
