Description
Technical field
The utility model relates to a kind of check-valves including valve chest, valve seat and flexible valve membrane.
Background technique
This check-valves with flexible valve membrane is particularly useful in automotive, and for example in brake boosterUpper use, wherein these check-valves are mounted between vaccum memory and vacuum source.In
This, check-valves prevents direction reflux of the fluid (especially air) from vacuum source towards vaccum memory, so that even if closing
Also negative pressure is kept when vacuum source and guarantees brake force power-assisted (Bremskraftunterst ü tzung).
On the one hand, this check-valves should usually have low cracking pressure, to ensure quickly to open valve, so that fluid can be with
Check-valves is flowed through along circulating direction.On the other hand, it needs that there is good resistance to pressure on cut-off direction, to ensure for example to exist
It provides to adequately protect when failure igniting (Fehlz ü ndung) and prevents compression shock.
To open and close check-valves, valve seat inside valve chest, being disposed with valve film on it is constructed with multiple
Outlet opening, these outlet openings are closed by valve film on cut-off direction and open on circulating direction.For example, having circle
The valve seat of outlet opening is known.This valve seat 28 on valve chest 2a is for example shown in FIG. 1.The valve seat has six
A circular through-hole is as outlet opening 30.However, this has the drawback that, on the one hand, flow cross section is not by ideal land productivity
With, and the high pressure loss is therefore generated in check-valves.But it is then cannot ensure in the case where expanding outlet opening in event
It provides and is adequately protected to prevent compression shock when barrier igniting.In the lesser situation of outlet opening, these outlet openings are very big
Renitency is impacted in degree, however flow resistance but dramatically increases.
Utility model content
Therefore, the task of the utility model is to propose a kind of check-valves, which is improved at above-mentioned aspect.
The task is achieved by the check-valves with features described below.Advantageous form of implementation is from as described below
Content in learn.
Check-valves includes valve chest and valve seat, which has cylindrical part, and the valve seat is in the cylindrical part
It is formed, perpendicular to the longitudinal axis orientation of the cylindrical part.Valve seat has outlet opening.Flexible valve membrane is arranged on valve seat,
The flexible valve membrane is configured at least partly opening outlet opening, to allow fluid in a first direction, i.e., only
It returns on the circulating direction of valve and flows through cylindrical part, or be configured for closure outlet opening, to prevent fluid second
On direction, i.e., cylindrical part is flowed up through in the opposite direction of check-valves or cut-off side.According to the utility model, outlet opening
It is defined by two relatively parallel curved sections.
In the valve seat with good compression resistance impact so far, outlet opening selects to obtain very little.Make us frightened
With being surprised, it can determine that now, low flow resistance be both able to achieve by the outlet opening defined by two relatively parallel curved sections,
It is able to achieve good compression resistance impact again.
According to the utility model, " two relatively parallel curved sections " further includes these following situations, and middle conductor is not
The bending radius deviation slightly from one another of accurately parallel extension and/or curve.Particularly, curved section is the line segment of conic section,
That is circle, oval, parabola or hyp a part.
In preferred form of implementation, outlet opening is configured to fan ring (Kreisringsektor).In such case
Under, curved section is round a part.
Advantageously, valve seat and valve chest are configured to one.
Outlet opening can be arranged at least one circumscribed circle (Umfangskreis).In this form of implementation, discharge
The partition (Steg) for being open and being disposed there between forms full circle.
In one embodiment, outlet opening is arranged at least two circumscribed circles.
Advantageously, outlet opening has the extension than smaller outlet opening in a circumferential direction in radial directions." row
The extension being open out in radial directions " is understood as that the spacing of relatively parallel curved section." outlet opening is in a circumferential direction
Extension " be understood to be in the arc length of the line medially extended between parallel curved section.It is improved by this structure type
The compression resistance impact strength of check-valves.
In one embodiment, valve seat has eight outlet openings.In this case, valve seat can be radially inner
Tool is there are four outlet opening in week, and in excircle tool there are four or eight outlet openings.
Partition can extend radially outwardly between outlet opening.
Spacing between the outlet opening of two radially adjoinings can be less than the extension of outlet opening in radial directions.
Particularly, the spacing between two outlet openings adjacent in a circumferential direction is less than outlet opening in circumferencial direction
On extension 50%.
