Description
Background technology
In transmission equipment, such as in the membrane pump for transmitting working media, work thin film is main using elasticity
Material is made.Using described transmission equipment, especially membrane pump, such as work materials/auxiliary material or work can be transmitted
Make medium, such as, as the reducing agent of watery urea liquid, described watery urea liquid is used for reducing in exhausted gas post-processing system
NO in waste gasXComposition.
However, the work thin film mainly made with elastomeric material is limited in in the at most about low pressure range of 6bar.
In principle, the purpose of this work thin film is can oscillatorily and constantly by coupling the mechanical component that is connected with actuator
Produce the low pressure for drawing or the alternation for transmitting the pressure of volume.
The work thin film using for this typically passes through backing plate and case lock and to external seal.
From work thin film this known to DE 41 19 228 C2 and its operation principle.In order to avoid in pressure alternation condition
Under be corrected, proposed according to the technical scheme of DE 41 19 228 C2, the elasticity of described work thin film, motion (get final product pivot
Turn) region by cushioning add ons apply prestressing force.Especially, using the supporting element being made of a foam material, with slow
Rush the intrinsic vibration that described work thin film forms noise.
In order to execute transmission motion, described work thin film must have the Hookean region deforming in execution transmission motion.
However, this proposes very high mechanical requirements to the Hookean region of described work thin film, and only there is the limited use longevity
Life.Additionally, when there is pressure differential, the Hookean region of described work thin film is heaved as balloon, so that described transmission body
Amass and depend on pressure.
Content of the invention
The present invention propose, for volume delivery fluid media (medium) and be configured on substantially disc-shaped work thin film by means of
Holding element makes following regional stabilities, and described thin flexible film deforms and highest when transmitting stroke in this region
Mechanical load.
Using described supporting element can the work thin film that used of local strengthening, and thus so that it is applied to higher
Operating pressure.Avoid described work thin film particularly in higher operating pressure that balloon-like occurs by described strengthening to become
Shape.This deformation makes the stereomutation of the component space by described work thin film gauge, and thus impact transmission quantity.Additionally, institute
The service life stating work thin film is obviously prolonged by using supporting element.
The stability of described work thin film can be improved further, and wherein, the stability of described work thin film is additionally led to
Cross metal insert, fiber and/or fabric insert to be strengthened.
Supporting element according to the present invention is embodied as support disk in one embodiment.
In another enforcement modification of the present invention, described supporting element is embodied as mushroom or Flos Tulipae Gesnerianae shape support
Structure.
In an advantageous manner, by described support disk or by using supporting collar, to work thin film, especially in institute
State the Hookean region of thin film underneath with being used for stable strengthening part.Described support disk or the manufacture material supporting collar
Can be metal material, such as plate, rare metal alloy steel or plastics, such as thermoplastic.Past in described work thin film
In multiple motion, when pressure increases, component space is constant big, and the volume of described component space keeps equal, because described
Support disk prevents the deformation of soft elastic part.
Supporting element, such as support disk or support collar are passed through according to thin film proposed by the present invention, supports and be clamped in
Two parts, between housing parts and intermediate plate.The sealing of described work thin film can be by the edge of described work thin film
The raised realization of radial seal that region is constituted.In order to make described elastomeric material expand when temperature improves, utilize in the present invention
The work thin film that supporting element is supported has expansion space.This expansion space is arranged on seal convexity in an advantageous manner and divides
Between rib and can make described elastomeric material temperature raise and receive medium when expand.Additionally, the unit in described thin film
Part space top, arranges an additional volume in an advantageous manner in its upside, to ensure described work thin film here
The expansion space of material.
Described supporting element, such as support disk or support collar, can be extruded, screwed tight, welding or also can quilt
Bonding.Described supporting element is expressed to from below on armature or piston, is described thin film in its upside, and therefore not
Must be injected in elastomeric material or be arranged in component space.Thereby eliminating the cloth in being generally disposed at component space
Put middle appearance sealing to interrupt, described sealing interruption leads to force to leak or damage.Actuator described in described armature or piston
A part, move back and forth and produced using described actuator and be delivered on described work thin film.
Preferably, by rounding, wherein, described circular radius is chosen as making described work thin film at the edge of described support disk
Launched on a radius by described armature or piston when moving back and forth.
In a favourable enforcement modification, downside is supported the supporting element of described thin film allows to be configured to support
Collar.This part can use metal material, such as to rush curved technology manufacture.The described advantage supporting collar is mainly to improve
Install, because pliable and tough wall expansion is possible.It is provided with additional gap, described peace in the described wall region supporting collar
Dress power alterable.In addition, this results in adding that the setting of the inner side of described Flos Tulipae Gesnerianae shape supporting element is located in radius region
Embossing, and the additional hardening in the face of the pressure that is therefore absorbed.
Feature according to work thin film proposed by the present invention in particular, in that, it can use in the case of pressure >=6bar,
And especially there is when for automotive field long service life.It can carry out volume delivery such that it is able to save pressure
Sensor.By allowing to obtain not relying on temperature by the work thin film that supporting element, such as support disk or support collar are supported
, there is not above-mentioned balloon effect, especially in high temperature and high pressure in the transmission performance of degree.
By the rolling radius of setting on support disk, described thin film is close to by described armature in whole reciprocating motion
To on described support disk.Thus obtain described Stabilization in each stage of described motion.
Additionally, described work thin film allows to be strengthened by introducing metal insert, fiber and/or fabric insert.This
Further improve the resistance to pressure of described thin film, and significantly extend the service life of described work thin film.
Keep equal using transmission volume is capable of according to work thin film proposed by the present invention, that is, do not rely on described thin
The expansion of membrane material and temperature impact.Equally, the dependency of described transmission volume versus pressure reduces.
