Be equipped with the movable armature of the described type of beginning by the solenoid valve of the known the above-mentioned type of DE102009022538A1, armature works as the valve member of solenoid valve.Can to be transferred armature or valve member by operation calutron, to occupy different running positions, it is for affecting the flowing of fluid, the especially flowing of pressure air.This solenoid valve relates to such as a kind of 3/2 selector valve, its valve member or armature can be positioned on two different running positions, a valve passage that can be connected with load or provide the supply passage of pressure medium with or be connected with an exhaust passage on this running position.In order to closed channel connects, arrange the seal element be made up of elastomeric material in the armature body be made up of ferromagnetic material, it is forced on the valve seat of solenoid valve on the corresponding running position of armature under sealing.Together with seal element to be stretched in armature body by spring mechanism, this spring mechanism is made up of the supported spring of the machinery be arranged in armature body inside.
The solenoid valve known by DE8530286U1 is also equipped with a movable armature, and its armature body comprises the seal element of a loading of the spring element by machinery.
Have a movable armature by the solenoid valve that DE102006022561A1 is known, it remains on a position and by means of permanent magnet by means of spring element and remains on another position.Armature has armature body, inserts one and the coefficient Sealing of valve seat wherein an end.
DE102010026548A1 discloses a kind of solenoid valve, and it has by the pre-tensioned push rod of spring element, in push rod, insert a seal element in end face side.Seal element remains on push rod in this wise by means of supporting element, and namely it is movable about push rod and discharges according to the relative position between push rod and seal element or close a passage through seal element.
By the known a kind of solenoid valve of DE102006053314A1, its valve member is made up of movable armature, and armature has ferromagnetic armature body, imbeds two seal elements be made up of 2 elastomeric materials in armature body.According to the running position of armature, or one or another seal element are forced on a valve seat.Because the elastomeric material of seal element trends towards expanding under the impact of oil with other liquid, therefore may function be produced in solenoid valve runs impaired, if the fluid that will control is infiltrated corresponding liquid, such as lubricant oil.The expansion of elastomeric material causes, and the total length of armature increases and armature lift reduces thus, and this reduces releasable channel cross-section.
The present invention is based on of task is taken measures, and overcomes the problem of the expansion of the parts be made up of elastomeric material of the movable armature of solenoid valve.
In order to solve this task, specify a kind of beginning in the movable armature of described type, spring mechanism is also made up of elastomeric material and is combined into sealing and the spring body of the one that is made up of elastomeric material together with seal element.
Not only start in the movable armature of described type but also at a kind of solenoid valve starting described type a kind of, this task is so solved, and namely spring mechanism is also made up of elastomeric material and is combined into sealing and the spring body of the one that is made up of elastomeric material together with seal element.
The volume that spring mechanism together with being stretched in armature body by seal element allows the seal element be made up of elastomeric material to carry out producing by expanding increases, and does not affect armature lift and therefore at a channel cross-section from releasable fluid passage on the position that valve seat rises.Changed by the length of the seal element limited that expands and compensated by spring mechanism, spring mechanism correspondingly bends.Unaffected in the case for the relative position required by seal action between seal element and armature body, because armature body is still crushed on by spring mechanism in the backstop that is arranged on armature body.The project organization of the particularly advantageously one of seal element and spring mechanism in the present invention, they are the sealing of the combination of the one that is made up of elastomeric material and the constituent element of spring body.Simplify manufacture and the installation of armature by this way significantly.Sealing and spring body can as element of construction manufactures and be also combined into armature with armature body as element of construction in a unified installation process in a unified manufacture process.Sealing and the integrated mode of structure of spring body also can realize very little size, even if this permission is applied in very little the solenoid valve built with very little armature type of building.The present invention such as can realize under being combined with the armature become by clavate armature or plate shape armature or pivot armature structure.In plate shape armature, sealing and the compact structure size of spring body also prove favourable especially, because the general very flattened structure of the armature body of plate shape armature and being therefore only seals and spring body provides very little installing space.

Below term " armature " is usually only used, although also refer to the function of armature 2 as valve member 3 thus.
The armature 2 of exemplary solenoid valve 1 is designed to clavate armature and has microscler, rod shapes, has longitudinal axis 6.The armature being designed to pivot armature is comprised according to the alternative structural type do not illustrated of solenoid valve 1 of the present invention, its motion switch is flip-flop movement or pivot movement, or comprise plate shape armature as armature, it substantially has plate shape shape and wherein motion switch 5 is directed at a right angle with board plane.
Solenoid valve 1 have one have calutron 4, usually by the elementary cell that reference character 7 represents, armature 2 can move relative to this elementary cell in the scope of its motion switch 5, wherein, motion switch is linear motion in an embodiment.Exemplarily, motion switch 5 is oriented in the longitudinal axis 6 of armature 2 axially.
Elementary cell 7 is passed by multiple valve passage 8, and they can be controlled by valve member 3 with being separated about the connection on its mutual fluid.
First valve passage 8a and the second valve passage 8b is set below valve passage 8.On first running position can seen from figure of armature 2, at these two valve passage 8a, the fluid connection between 8b is interrupted.Armature 2 can occupy on second running position different from the first running position in addition, and the fluid herein between the first valve passage 8a and the second valve passage 8b connects and is released.
Two can be restricted to by the quantity of the controllable valve passage 8 of armature 2.In this, solenoid valve 1 is now especially made up of 2/2 selector valve.In a kind of structural type favourable equally, this structural type realizes in an embodiment, solenoid valve 1 is 3/2 selector valve, it is except two already mentioned first and second valve passage 8a, the 3rd valve passage 8c is also had beyond 8b, it is connected and valve passage 8a other with two on the second running position of armature 2 with the second valve passage 8b separated from the first valve passage 8a on the first running position of armature 2, and 8b divides out.Advantageously utilizing valve passage 8 times, first valve passage 8a is the supply passage that can be connected with the pressure source of outside, second valve passage 8b is the service aisle 8b that can be connected with the load of the outside that will operate and the 3rd valve passage 8c is the relief passage be connected with air, it is exhaust passage, if solenoid valve 1 is used to pilot pressure air, this is the preferred application target of solenoid valve 1.But unlike this, solenoid valve 1 also may be used for controlling liquid pressure medium.
Armature 2 is contained in a valve chamber 9 be constructed inside in elementary cell 7 movingly.Whole valve passage 8 passes in this valve chamber 9.
Armature 2 has two mutually on the contrary at the first and second axially directed end faces 10,11 of longitudinal axis 6.The passway of opposite with the first end face 10 is the first valve passage 8a, its is surrounded by the first valve seat 12 in the face of armature 2.The passway of opposite with the second end face 11 is the 3rd valve passage 8c, it is surrounded by the second valve seat 13, and it is also in the face of armature 2.Two valve seats 12,13 are configured to and relative to axially the giving prominence to of longitudinal axis 6 of armature 2 at it with respectively meeting destination flange-shaped.
?in the design proposal as 2/2 selector valve of solenoid valve 1, naturally cancel the second valve seat 13.
Each valve seat 12,13 is assigned sealing and the spring body 14,15 of an one of armature 2.Armature 2 comprises two sealings and spring body 14,15, and one of them (14) coordinate with the first valve seat 12 and second (15) coordinate with the second valve seat 13.If solenoid valve 1 only has an only valve seat, armature 2 meets the destination sealing that also only equipment one is only and spring body.
Each sealing and spring body 14,15 be positioned at armature 2 with valve seat 12, one of 13 opposite those end face 10,11 places.Each sealing and spring body 14,15 comprise a seal element be made up of elastomeric material 16, and it has and the valve seat 12 distributed, sealing surface 17 faced by 13, when armature 2 occupies a corresponding running position, sealing surface is fitted in valve seat 12 opposite respectively hermetically, on 13.
Except two one, the sealing of rubber elasticity and spring body 14, beyond 15, armature 2 yet comprises one at least in part and in an embodiment at its on the whole ferromagnetic the armature body 19 be configured to.Armature body 19 is equipped with each the space 20,21 that sealing and end face 10,11 place of spring body 14,15 have a blind-hole type, and the sealing of distribution and spring body 14,15 meet destination and be accommodated in space on the whole at it.
In motion switch 5, armature body 19 and two sealing and spring body 14,15 moved uniformly respectively.
In order to seal the space 20 remaining on each distribution with spring body 14,15, in 21, armature body 19 will be furnished with corresponding backstop 22,23.Best backstop 23 is formed by a radial protrusion 24 respectively, it surrounds the space 20 distributed, one of 21 is arranged in corresponding end face 10, the opening 25 at 11 places, its diameter is slightly smaller than space 20, the diameter of the accommodating section 26 then in the axial direction of 21, sealing and the spring body 14,15 of distribution are contained in this space.
Sealing and spring body 14,15 be supported on by its seal element 16 backstop 22,23 of distribution with on the surface of its axially facing.At this, seal element 16 is forced into backstop 22, on 23 constantly by spring mechanism 18 on the direction of the valve seat 12,13 distributed.Spring mechanism 18 is so designed to, and seal element 16 and the running position of armature 2 to be pressed in backstop 23 and to keep in touch with this backstop 23 by independently.Do not specify seal element 16 from backstop 22 in solenoid valve 1 runs, 23 lift.
In an advantageous manner, spring mechanism 18 is the same with seal element 16 is made up of elastomeric material.They are the same with the seal element 16 distributed is seal and the interconnective integratedly constituent element of spring body 14,15 or portion's section.Therefore can say, sealing and spring body 14,15 are elastomeric elements of an one, it has the seal section forming seal element 16 and the spring section forming spring mechanism 18, wherein, these two portion's sections are constituent elements of the component of the one of a sealing and spring body 14,15 form.
Spring mechanism 18 is effective between seal element 16 and armature body 19.The action direction of spring mechanism 18 and the moving direction of motion switch 5 and axial consistent exemplarily with longitudinal axis 6.In addition also ground identical with the action direction of spring mechanism 18 is directed for sealing surface 17.
Preferably sealing and spring body 14,15 have microscler shape.Sealing and spring body 14,15 have longitudinal axis 27, and its orientation is consistent with the direction of motion switch 5.Sealing surface 17 meets the axially orientation of destination at this longitudinal axis 27.
Spring mechanism 18 being axially forced into backstop 23 at longitudinal axis 27 of seal element 16 by distributing.
In order to support relative to armature body 19, spring mechanism 18 coordinates with the bottom surface 28 of the axis in the space 20,21 of the blind-hole type distributed in an embodiment.Meet destination, sealing and spring body 14,15 are arranged on space 20 in this wise, in 21 or in its accommodating section 26, spring mechanism 18 is by pre-tensioner or have certain precompression, thus sealing and spring body 14,15 flexible pre-tensioner under be clamped in the axis in backstop 23 and space 20,21 bottom surface 28 between.In the case, sealing surface 17 be arranged in opening 25 region or with faced by it.Sealing surface 17 can be close by corresponding opening 25.
On the first running position can seen from figure, armature 2 is positioned such, it seal with the first valve seat 12 distributes first and spring body 14 is fitted on the first opposite valve seat 12 with its sealing surface 17 under sealing.By this way, the first valve passage 8a is closed.On this first running position, the second sealing and spring body 15 lift from the second valve seat 13 distributed, and the 3rd valve passage 8c and valve chamber 9 are fluidly connected and fluidly can be communicated with the second valve passage 8b by valve chamber 9 from armature 2 side in side thus.
On the second running position, situation is just in time contrary.Second sealing and spring body 15 are now fitted on the second valve seat 13 with the sealing surface 17 of its seal element 16 under sealing herein, and side by side armature 2 and therefore first sealing and spring body 14 lifted from the first valve seat 12, thus by valve chamber 9 set up between the first valve passage 8a and the second valve passage 8b fluid connection.
In order to obtain the airtight quality of pursuit, armature 2 at its valve seat 12 in order to the running position of sealing purpose being crushed on distribution by certain confining force each, on 13.Confining force neutralizes from outside importing armature body 19 and is delivered to the seal element 16 of each distribution via spring mechanism 18 from armature body.The elasticity of spring mechanism 18 is so selected, the pretightening force be applied on seal element 16 by them is greater than confining force respectively, ensures thus, when seal element because the confining force of effect is crushed on opposite valve seat 12, time on 13, seal element 16 does not lift from the backstop 23 of distributing.
But on the other hand, spring mechanism 18 can the stereomutation of compensation sealing element 16, it produces in the elongation axially of its longitudinal axis 27 along with seal element 16.Elastomeric material is trending towards expanding when such as oil contact with liquid medium, and this so shows in an embodiment, and namely seal element 16 and sealing surface 17 are at a right angle, namely at longitudinal axis 27 axially, experiences the increase of length.But based on according to design proposal of the present invention, this length of seal element 16 changes the such elongation not causing armature 2 because seal element 16 and especially sealing surface 17 be prevented from opposite valve seat 12,13 by backstop 23 direction on expand.On the contrary, the elongation of seal element 16 acts on the direction of spring mechanism 18 or on the direction of the axial bottom surface 28 in space 20,21.Therefore the axial spacing when seal element 16 extends between seal element 16 and the bottom surface 28 of working as the axial support surface 28a being used for spring mechanism 18 in space 20,21 reduces.This expansion becomes possibility due to the elasticity of spring mechanism 18.Represent at 29 place's dotted lines in the Local map of the amplification of Fig. 1, how seal element 16 axially extends with how floor spring mechanism 18 related to this has experienced a distortion or compression owing to expanding.
Although therefore the expansion of seal element 16 still realizes: seal element 16 can be fitted in the valve seat 12 of distribution with the sealing force limited, on 13.In addition realize, although the relative position of the axis of the expansion of seal element 16 between sealing surface 17 and armature body 19 does not still change, all the time the flow cross section of constant size is discharged thus, if armature 2 is positioned such, namely seal element 16 is from the words that the valve seat 12 or 13 distributed lifts.
In order to obtain the function of hope, seal element 16 arranges the ratio elasticity that the spring mechanism 18 implemented together with seal element 16 is less in the element of construction of one in the destination that axially meets of longitudinal axis 27.This can such as so realize, and namely use an elastomeric elements formed by multiple parts as sealing and spring body 14,15, the portion's section wherein forming spring mechanism 18 is made up of the elastomeric material softer than the seal section limiting seal element 16.But simpler and more advantageously, realize different flexibilitys by the mutually different structuring of seal element 16 and spring mechanism 18.In this case, sealing and spring body 14,15 can be made up of consistent elastomeric material on the whole, and this is this situation in an embodiment.
In an embodiment, to be configured to seal element 16 pieces of shapes or plate shape.It meets destination and has circular cross-sectional profiles in outside.Preferably it cylindrically constructs.In addition advantageously seal element 16 is made up of solid material.
Spring mechanism 18 is connected on axially contrary with sealing surface 17 end face in an embodiment, is namely integrally connected on seal element 16 dorsally.They meet destination sleeve ring shape ground structure, and wherein, they especially axially go from seal element 16 is outstanding on flange-shaped ground.Under uninstalled state, spring mechanism 18 meets destination on outer circumferential face, has moulding that is columniform or a little concavely arch, and wherein, they are after being installed in armature body 19, as seen from figure, because the pre-tensioner of axis is also radially retracted a little further.
Best spring mechanism 18 is arranged coaxially with seal element 16.
In addition advantageously, the spring mechanism 18 be configured to as sleeve pipe or ring structure is segmented under each single spring section 18a of formation in the circumference of longitudinal axis 27.This is for this embodiment and is especially clearly from Fig. 2.Each independent spring section 18a by comparison axially going from seal element 16 is outstanding and one after the other arranges at intervals on the circumference of longitudinal axis 27 with arm on dorsal part, wherein, meet destination between adjacent in the circumferential spring section 18a and an air gap 30 is set respectively.
Obviously, especially spring mechanism 18 also can be structured with method in another manner, such as bellow type or spiral coil.
Based on one mode of structure, sealing and spring body 14,15 can manufacture very simply and in armature body 19 installation.This embodiment illustrates sealing and the possible mounting type of two of spring body 14,15.Armature body 19 constructs in the mode of multiple part in this embodiment on the whole, and wherein, it has the main body 31 limiting corresponding space 20,21.Backstop 23 is passable, and as illustrated in conjunction with the second sealing and spring body 15, be the constituent element of the one of this main body 31, the space 21 of whole blind-hole type is by main body 31 thus, is namely limited by the constituent element of an one of armature body 19.In order to install in the space 21 distributed, sealing and spring body 15 are radially compressed in short time and are pressed in the space 21 of distribution by opening 25 herein.Sealing and spring body 15 are especially buckled into.When sealing and spring body 14,15, especially in the region of its seal element 16, when having enough sheatheies, this is possible.
Alternatively, also there is possibility, as illustrated in conjunction with the first sealing and spring body 14, the constituent element of backstop 22 as the backstop 32 separated about main body 31 being realized, previous by sealing with after spring body 14 inserts in the space 20 of distribution, backstop is fixed in main body 31.Backstop 31 is such as that annular solid is received in main body 31 with being inserted into coaxially and/or twisting.
