Summary of the invention

The object of the invention is at least to reduce the shortcoming of prior art level.

This problem solves by the feature of claim 1 and 15.

According to the present invention, at valve actuating device, especially in the hydraulic circuit of door closer or swing door leaf operator, be provided with valve, be specifically used for blocking and/or the motion of damper door.This valve actuating device is suitable for the door that open and/or closed connects.Valve actuating device has housing.Valve is suitable for use in valve actuating device, to affect the flowing of hydraulic fluid of valve actuating device, thereby it can block or discharge flow of hydraulic fluid.

Valve of the present invention especially comprises lining and sliding part.Sliding part is directed in lining, so that can length travel and by longitudinally movable path pre-tension of back-moving spring.Sliding part has the stop surface for hydraulic fluid, and this stop surface is configured to make flow of pressurized physical efficiency to be pushed against described stop surface.This stop surface is a part for sliding part, is correspondingly a part for valve body, and it is pushed the opposite edges that are resisted against in the lining that is arranged on valve by means of back-moving spring.This means, due to the effect of back-moving spring, stop surface is pressed against in opposite edges with fluid sealing mode and thereby blocks flowing of hydraulic fluid.According to the present invention, sliding part is set to from outside and mechanically loads, to resist the effect of back-moving spring.This means, for example, in the time closing connected door, sliding part can be pushed by the working piston of valve actuating device in the direction of back-moving spring, makes stop surface be lifted away from opposite edges, and thereby makes at least in part the mobile blocking action of hydraulic fluid be eliminated.This means, sliding part is set to from outside and mechanically loads, to resist the effect of back-moving spring and away from opposite edges.Because the spring of sliding part loads supporting role, in the time stopping mechanical load, sliding part by back-moving spring in the direction of opposite edges by automatically toward pushing back, if make active force or the non-existent words of mechanical load lower than back-moving spring, the stop surface of sliding part finally can arrive contact position again, with fluid sealing mode against opposite edges.

The housing that valve is inserted to valve actuating device allows valve to be arranged in the valve actuating device having assembled, and if necessary, allows to remove it, and therefore for example allows to change it.

Preferably, valve body and back-moving spring are contained in lining.

Favourable other development of the present invention is the theme of dependent claims.

Preferably, sliding part is set for from lining outstanding, wherein one end back-moving spring dorsad.This has superiority, because the motion path of working piston in the direction of back-moving spring can for example limit by lining.In this meaning, sliding part can only move upward in the side of back-moving spring, until it is concordant with lining on outside.In this case, the actuating device of machinery is possible, for example above-mentioned working piston, and its external dimensions exceedes the external dimensions of sliding part.For especially this situation of the working piston in the valve actuating device of hydraulic pressure, working piston moves in its corresponding housing along inwall in a fluid tight manner.As a result, for constrained motion path, do not need extra safety precaution.

Especially, (hydraulic fluid need to the flow through) distance between sliding part and lining can be dimensioned, and makes in the time that opposite edges are lifted away from, and flowing of hydraulic fluid is still obstructed.Thereby, the damping of the door being connected is opened and/or damping is closed and become possibility in very simple mode.

Preferably, stop surface is arranged to tilt at angle with respect to the longitudinal movable path of sliding part.Thereby, produce a kind of tapered slope for hydraulic fluid.The advantage of this generation is, opposite edges and tapered slope be always punctually along straight line or the mutual butt of curve, compared with flat butt, and the sealing function that this causes better, correspondingly more easily realizes.Preferably, in the direction of sliding part, correspondingly the angle in the direction of valve body is acute angle and is advantageously approximately 60 °.

In the side towards lining, sliding part preferably has recess, and this recess is limited by stop surface in a side, extends along the longitudinal movable path of sliding part, surround out a cylindrical hollow space for hollow preferably together with lining, and be hydraulically connected to the hydraulic connecting portion of lining.The advantage that recess has is that sliding part can move along the longitudinal extension part of lining, and can not interrupt the fluid communication between sliding part and lining.

In addition or as selecting, valve also comprises attached, lining inserts this attached and attached and sets for and insert regularly hydraulic door actuating device.Therefore, attached this means for valve of the present invention is fastened to valve actuating device, and with respect to the housing of valve actuating device, attached represents the parts of the fixed and arranged of valve.

In a side of the housing towards valve actuating device, preferably, attached has recess equally, this recess along in attached direction of insertion in the housing of valve actuating device, correspondingly extend in fastening direction, equally with together with the housing of valve actuating device, surround out a hollow circle tube hollow space preferably, and be hydraulically connected to the fluid pressure line of attached and housing fluid pressure line the two.The advantage of recess is to allow attached to insert valve actuating device, and the fluid pressure line that is wherein connected to valve may be positioned on the corresponding opposite side with respect to valve, and is still hydraulically connected to the recess of attached.Thereby, improved the range of application of valve, and thereby its application be widely.

Preferably, valve of the present invention also comprises adjusting part, and this adjusting portion is divided and is arranged in attached, to vertically move and to engage with lining, if it is vertically moved in attached, it pulls lining.Therefore, the position of lining and sliding part can regulate with respect to corresponding valve actuating device in attached.Sliding part for example activates by the working piston of valve actuating device.This moment, if working piston is further arranged on valve actuating device inner side with respect to attached, the above-mentioned arrangement being made up of sliding part and lining can move upward in the side of working piston, although attached does not change its position.In addition, lining as above can limit the motion path of the mechanical load element of valve actuating device.By regulate, correspondingly make lining attached middle displacement, the displacement path of described loading element from but adjustable.Therefore the range of application of valve is also enhanced, and thereby its application be widely.

According to the present invention, regulate part and lining energy unitary construction, thereby simplify the structure of valve.

Adjusting portion is divided and is arranged in attached, to preferably can rotate freely.Thereby, by adjusting portion is divided with respect to attached rotation, can use for example screwdriver to regulate part to move into the inner side of valve actuating device or to make to regulate part to move in the opposite direction, this simplifies the operability of valve.

In the side towards attached, lining preferably has recess equally, recess extends along the longitudinal removable path that regulates part, surrounds out a hollow space together with attached, and be hydraulically connected to the hydraulic connecting portion of lining and attached fluid pressure line the two.The advantage of recess is that lining can the motion in attached by regulating part, and the fluid that can not interrupt between lining and attached flows.This situation meets the extensive use of valve of the present invention equally.

Preferably, to be configured to be circumferential to one of above-mentioned recess.Thereby, between each recess and the part of direct neighbor, form hollow circle tube hollow space.This has superiority, and can in each adjacent part, rotate, and can not unclamp each hydraulic connecting portion because have the part of recess.This means, hydraulic connecting portion is maintained the position of rotation that is independent of the part with recess, thereby and always can ensure hydraulic connecting, this has increased processing safety.

Preferably, sliding part also has through hole, the space hydraulic connecting between this through hole and sliding part and lining and extending in the direction of the actuation element of valve actuating device or in the direction of closing sequence control.Through hole guides the fluid stream between described space and the exterior lateral sides of valve, and wherein stop surface can be arranged in described space.This exterior lateral sides is the another location compared with the position of the housing that is hydraulically connected to valve actuating device with attached.

In the one end in space dorsad, sliding part preferably has a continuous recess or hole, and this recess or hole are substantially in the transversely extension in longitudinal movable path of sliding part and be configured to guide continuously and leave through hole.Thereby, produce fluid passage, even the working piston butt sliding part of for example valve actuating device, this fluid passage has also ensured the fluid communication between through hole and valve actuating device, this has increased processing safety.This hole is easy to realize by holing.

Preferably, in the one end in space dorsad, lining also has a continuous recess or hole, and this recess or hole are arranged essentially parallel to the continuous recess at sliding part place or the longitudinal extension part in hole extends.Thereby, also in lining, produce fluid passage, even the working piston butt sliding part of for example valve actuating device, this fluid passage has also ensured the fluid communication between sliding part and valve actuating device, this situation further increases processing safety.

Brief description of the drawings

According under regard to the explanation of some embodiments and with reference to accompanying drawing, further details of the present invention, advantage and feature will become obviously, in the accompanying drawings:

Fig. 1 shown according to the diagram simplified cross-sectional view of half portion of the valve at the first operating position of first embodiment of the invention,

That Fig. 2 has shown is corresponding with valve in Fig. 1, at the second operating position and be the diagram of the valve of modification slightly,

That Fig. 3 has shown is corresponding with valve in Fig. 1, in the 3rd operating position and the same diagram of the valve of modification slightly that is,

Fig. 4 shown according to the sectional view of the valve of second embodiment of the invention, and

Fig. 5 has shown the valve according to third embodiment of the invention.

Detailed description of the invention

In Fig. 1 to Fig. 3, show in a simplified manner respectively the valve 1 according to first embodiment of the invention, wherein according to diagram, only the first half is selected also illustrates in the drawings, half portion of the visible valve in longitudinal axis L top, represents with valve 1 below.

Correspondingly, valve 1 has lining 2, and sliding part 3 is directed in lining 2.In this case, sliding part 3 in the direction of longitudinal axis L that is parallel to lining 2 by means of back-moving spring 4 by prestressing, thereby and be pushed against opposite edges 6, these opposite edges 6 are arranged on lining 2 inner sides and are positioned at lining 2 places.

For this reason, sliding part 3 has stop surface 5, the angle [alpha] indicating according to Fig. 3, and this stop surface 5 is arranged to tilt with respect to longitudinal axis L.Due to the effect of back-moving spring 4, the stop surface 5 of sliding part 3 is with fluid sealing mode butt opposite edges 6.This means, the sealing contact between stop surface 5 and opposite edges 6 produces the blocking action of valve 1.

Lining 2 also has hydraulic connecting portion 7, and in this example, hydraulic connecting portion 7 is set as passing completely through the flow channel of lining 2.Outer recess 8 in lining 2, through the pipeline portions of attached 10 9, and through attached 10 another recess 11 now, hydraulic connecting portion 7 and fluid pressure line 12 hydraulic communication, fluid pressure line 12 leads to hydraulic power source, and hydraulic power source does not illustrate in greater detail in the drawings.Hydraulic channel 12 is preferably arranged in the housing 13 of the valve actuating device (being door closer or swing door leaf operator) not being shown specifically, because under installment state, valve 1 is attached in the hydraulic circuit of this valve actuating device.

The conventional flow direction of the hydraulic fluid H of valve actuating device 1 in valve 1 is by arrow represent.Flow direction preferably, corresponding to the direction of opening of valve actuating device (door that correspondingly connected), wherein valve 1 blocks flowing of fluid.This for example in fact under any circumstance prevents that connected door from exceeding maximum open angle.If exceeded maximum angle, valve actuating device is by destroyed or for example collide on wall.

In Fig. 1 to Fig. 3, arrow H represents the flow direction of hydraulic fluid H, if the door for example connecting or valve actuating device are carried out closing movement, hydraulic fluid H can be introduced into when through hydraulic connecting portion 7, is correspondingly introduced in the outer recess 14 of sliding part 3.By hydraulic fluid H is introduced in recess 14, hydraulic fluid H is pulled on stop surface 5.

Under the state shown in Fig. 2, for example, wherein door is opened, and flowing of the hollow space of fluid through sliding part 3 and lining 2 exists more slowly or not.This means, the common closer spring of valve actuating device can utilize its whole active force to start bolt down procedure, and this initial acceleration for needs door is favourable.

For example, due to the motion away from valve 1 related to this of (being configured to piston 24) actuating device of the gradual motion of door and valve actuating device, the stop surface 5 that back-moving spring 4 makes sliding part 3 moves up in side near opposite edges 6 more and more.As especially seen better in Fig. 3, in the region of opposite edges 6, the hollow space between sliding part 3 and lining 2 is narrower.This narrows and hinders flowing of fluid, and thereby causes the slower speed of door.Closing velocity for example thereby in the time that closing movement finishes is obstructed, and this has caused that damping closes.

Significantly, valve 1 can be inserted into equally, because in the time that door is just being opened, stop surface 5 is pushed away opposite edges 6 by piston 24.In this case, in the time that door is opened motion end, having realized damping opens.

Especially as shown in Figure 2, valve 1 preferably has bolt portion 15, for example, be the shape of soket head cap screw head.At outside place, bolt portion 15 at least preferably has male thread portion 15a on some parts, and bolt portion 15 is screwed in the negative thread part 10a being arranged in attached 10 by this male thread portion 15a.Connect and be penetrated into outside in order not make hydraulic fluid pass this screw, preferably, bolt portion 15 can have around groove 15b on outside, and seal 16 (for example shape of O type circle) is inserted into this around in groove 15b.Therefore, seal 16 inserts between attached 10 and bolt portion 15 with fluid sealing mode because advantageously seal be configured to be flexible and be compressed in groove 15b and the opposite inner face of attached 10 between.

Make bolt portion 15 rotations cause that bolt portion 15 is the attached 10 interior translational motions along longitudinal axis L.

Through spline adapter, for example lining 2 preferably utilizes anti-rotation protection to be accommodated in the housing 13 of valve actuating device.For example, as seen in Figure 2,, housing 13 has the protuberance 13b for this object, and protuberance 13b extends and gives prominence in the direction of lining 2 along longitudinal axis L.2 of linings have the groove shape guidance part that is track or guiding recess 2d shape.Guiding recess 2d thereby only can move along protuberance 13b, thus lining 2 only can be in attached 10 translation mobile, according to Fig. 2, this is translation on left and right directions.Another advantage of this linear guide of lining 2 is, fluid pressure line 9 and hydraulic connecting portion 7 can only change their position toward each other along straight line, and for example, along the straight line parallel with longitudinal axis L, this increases processing safety.

As shown in Figure 3, the linear guide of lining 2 also can be realized by attached 10.For this reason, compared with Fig. 1 and 2, attached 10 is set to longlyer, and for example has guiding recess 10d, and lining 2 is directed to can vertically move along longitudinal axis L by means of constructed guiding protuberance 2h in guiding recess 10d.

Set the reception space for back-moving spring 4 lining 2 with the part place away from bolt portion 15 sliding part 3.For this reason, on the inner side of lining 2 and on the outside of sliding part 3, both have respectively recess 2a or 3a, and recess 2a or 3a are set as respectively around recess.Thereby, the cylindrical hollow space that has produced hollow between lining 2 and sliding part 3.As selection, recess 3a is removed, and recess 2a is by self producing this hollow space, or turns around.Back-moving spring 4 be inserted into this hollow space and with it that end towards bolt portion 15 prop up the abutment surface 2b by lining 2.This for example means that back-moving spring 4 is set to helical spring.Abutment surface 2b preferably constructs by the wall that limits recess 2a of lining 2.Back-moving spring 4 utilizes it to prop up by spring fitting 17 that end of bolt portion 15 dorsad.In the example depicted in fig. 1, spring fitting 17 is constructed by means of inserting the circumferential hoop of sliding part 3 ring in groove 3b.Ring preferably has the cross section of rectangular shape, to provide good abutment surface for back-moving spring 4.Groove 3b prevents that the left and right directions in hoop Fig. 1 and Fig. 2 from moving.

As selection, spring fitting 17 is only supported in the direction of back-moving spring 4, example as shown in Figure 2, because back-moving spring 4 is by pre-tensioner, so it prevents that spring fitting 17 from moving up in the side of back-moving spring 4.In the example shown, it is upper that spring fitting 17 is placed in recess 3a, and it is upper that back-moving spring 4 is also placed in recess 3a, therefore makes spring fitting 17 not need extra reception space.

As selection, as shown in Figure 3, sliding part 3 has male screw portion 3f in the end of bolt portion 15 dorsad, is nut or the annular spring fitting 17 with negative thread and is swirled to male screw portion 3f.Thereby, regulate pre-tensioning and thereby to regulate the homing action of back-moving spring 4 be possible.Advantageously, the cross section of ring has non-circular outline, for example, be outer-hexagonal shape shape, ring can for example be rotated by open-end wrench, thereby move in the direction of abutment surface 2b or away from abutment surface 2b translation, and can regulate thus the pre-tensioning of back-moving spring 4.

For maximum possible degree reduce the leakage loss in the direction of back-moving spring 4, sliding part 3 preferably further has circumferential hoop around groove 3c, seal 18 to be to insert circumferential hoop around groove 3c with the similar mode of seal 16, thereby and is arranged between lining 2 and sliding part 3 with fluid sealing mode.

And, similarly in that side relative with bolt portion 15 of fluid pressure line 9, lining 2 preferably has with the similar circumferential hoop of groove 3c, 15c around groove 2c, seal 19 inserts circumferential hoop around groove 2c to be similar to the mode of seal 16,18, be therefore arranged in attached 10 with fluid sealing mode and lining 2 between.

For keep leakage loss between housing 13 and the valve 1 of valve actuating device as far as possible low, preferably on the both sides of hydraulic channel 12, be all provided with seal 20,21, seal 20,21 is preferably arranged between housing 13 and attached 10 in clamped mode.For this reason, preferably in position locate to there is circumferential hoop around groove for attached 10, be respectively recess 10b, 10c.But at the relative position place corresponding with groove 10b, 10c, housing 13 also can have recess or groove 13a, in this case, recess or groove 13a be positioned at inner side and around.

Preferably, in the right side of fluid pressure line 9 and/or the region in left side, attached 10 has external diameter, and this external diameter is less than the internal diameter of housing 13 in the region being associated, and forms thus recess 11.Thereby, the cylindrical hollow space of hollow be for example formed on attached 10 and housing 13 between.Due to this hollow space, for fluid is flowed, fluid pressure line 9 needn't be aimed at fluid pressure line 12.But fluid pressure line 9,12 can be about arranged offset each other.Thereby, can make valve 1 standardization, standardized valve 1 can be used for heteroid valve actuating device, and this contributes to again to reduce manufacturing cost.

In order to make bolt portion 15 can not only move up and promote lining 2 but also mobile lining 2 in the opposite direction in the side of valve actuating device, bolt portion has block device (catch device) towards a side of lining 2.

In the example depicted in fig. 1, block device is constructed by means of the block part 15c of annular preferably, and it sets transversely outstanding and outstanding towards lining 2 in the direction of longitudinal axis L preferably for.Lining 2 preferably has the recess 2e complementally constructing with block part 15c.This means, block part 15c can say the breech lock by recess 2e.From certain consumption of power, block part 15c and recess 2e are constructed to be permeable to engage and/or be disengaged, thereby are conducive to dismounting and install.

As selection, although do not illustrate in figure, bolt portion 15 has the recess that is similar to recess 2e, and lining 2 has substantially and the protuberance of this recess complementation.

As selecting, as shown in Figure 2, block part 15c constructs by means of the protuberance lying on lining 2 with clamping mode again.This means, pull lining 2 by means of bolt portion 15 and realize by clamping or rubbing action.

As selecting, as shown in Figure 3, block part 15c constructs by means of recess equally, makes to form hollow space between recess 2e and 15c again.The block part 23 preferably with the shape of ring is inserted this advantageously in the hollow space of ring-type.

Because bolt portion 15 is rotated with respect to lining 2, so annular shape is favourable.

Now the task of bolt portion 15 will be explained based on Fig. 2 and Fig. 3.If bolt portion 15, under the condition shown in Fig. 2, can almost flow from the hydraulic fluid H of fluid pressure line 9 in the clear in hydraulic connecting portion 7, because the almost alignment mutually of fluid pressure line and hydraulic connecting portion.But under the condition shown in Fig. 3, wherein bolt portion 15 further moves up in the side of fluid pressure line 9, initially must be through the narrower space 22 attached 10 and lining 2 before arriving hydraulic connecting portion 7 from the hydraulic fluid H of fluid pressure line 9.Thereby flowing of fluid is obstructed significantly.As a result, back-moving spring 4 need to apply less power the stop surface of sliding part 35 is pressed against with fluid sealing mode the opposite edges 6 of lining 2.In addition, this narrows and makes the motion of the door leaf can damping connecting.Obviously, space 22 can be configured to make flowing hardly of fluid or not interrupted.Therefore, provide wherein damping and blocked the valve 1 that action can be conditioned.The bolt portion 15 thereby come-at-able simple selection from outside is provided, allows valve 1 to be suitable for each valve actuating device.

Bolt portion 15 also has another conclusive advantage.Within 10 o'clock, move simply removing attached from housing 13 in the time being inserted into housing 13 and if necessary for attached 10.In other respects, attached 10 is fixedly arranged about housing 13.This means, seal 20,21 slips along housing are low to negligible degree.This means, seal 20,21 is subject to hardly or is not subject to mechanical wear, thereby last very long.Not at least this situation for seal 18.During each open and/or closed program, the piston 24 of the illustrated valve actuating device of part in the drawings, for example working piston, pushes the abutment surface 3g of valve body 3, and necessary time, pushes abutment surface 3g in the direction of bolt portion 15.Between each moving period of valve body 3, thus seal 18 along lining 2 towards contact surface slide and thereby be subject to higher wear.Result is that if necessary, seal 18 need to be replaced.Due to bolt portion 15, not whole valve 1, and be only that bolt portion 15 need to be unscrewed with lining 2 and valve body 3.Therefore, maintenance cost reduction and self maintained are simplified.

As shown in Figure 3, housing 13 is modified slightly.As can be seen, housing 13 is substantially similar to the housing 13 of Fig. 1 and Fig. 2.But compared with these figure, fluid pressure line 12 is set skew to the right for.Importance along the wider recess 11 of longitudinal axis L becomes obvious this moment.Due to this width, valve 1 can use in the housing 13 with heteroid fluid pressure line 12, as long as inserting under the state of valve 1, each fluid pressure line 12 and recess 11 hydraulic communication of attached 10, thereby hydraulic fluid between fluid pressure line 12 and recess 11 to exchange be possible.This means, recess 11 has improved the versatility of valve 1.

Because the operation between stop surface 5 and opposite edges 6 connects, provide the valve 1 that can insert valve actuating device and remove from valve actuating device with plain mode.Thereby valve 1 can be together with closing sequence controller have not only used as check mechanism but also as blocking device.In this case, piston 24 is replaced by the actuation member (not detailed icon) with closing sequence controller, or foundation can be by this actuating device of the valve actuating device startup being associated with inactive door leaf, therefore make the valve 1 of swing leaf that flowing of hydraulic fluid can maybe can not be carried out, thereby the valve actuating device that is associated with swing leaf of realization and braking or release.

As shown in Figure 1, flow or flow in the opposite direction from the hydraulic fluid H of fluid pressure line 12 in the direction of piston 24, this being configured within being present in space 25 between lining 2 and sliding part 3 and sliding part 3 of flowing is that continuous through hole 3d carries out.Through hole 3d in the direction of recess 14 from exterior guiding hydraulic fluid H, or turn around.If piston 24 is in the position shown in Fig. 2, likely, it makes hydraulic fluid flowing in this region be obstructed significantly or get clogged straightly against the external surface 2f relative with piston of lining 2.For fear of this situation, according to Fig. 1, for example piston has through hole 24a, and through hole 24a sets about through hole 3d, makes hydraulic fluid H can flow through through hole 24a.Hydraulic fluid H represents through the double-head arrow that flows through of piston 24.

As selection, as shown in Figure 3, piston 24 has the recess 24b of groove shapes, hydraulic fluid H from through hole 3d is laterally discharged from piston 24 by the recess 24b of this groove shapes, correspondingly guided by recess 24b and be directed to through hole 3d by recess 24b from the hydraulic fluid H of the side of piston 24, as represented with double-head arrow equally.

As selection, in the end towards piston 24, as shown in Figure 2, sliding part 3 has the recess 3e that is similar to recess 24b setting.In addition or as select, in the end towards piston 24, equally as shown in Figure 2, lining 2 also have be similar to recess 24b set recess 2g.The fluid stream that flows through sliding part 3 and lining 2 in this stub area is represented by double-head arrow equally.This structure is allowed for having had the valve actuating device of hermetic piston 24, and this has widened application.

Particularly, as seen in Fig. 1, attached 10 preferably has male screw portion 10e, in the negative thread part 13c of the complementally structure of the housing 13 that is screwed into door actuator by means of this male screw portion 10e for attached 10.For this reason, attached 10 also preferably has bolt portion 10f, and this bolt portion 10f preferably has non-circular exterior contour, for example, adopt outer-hexagonal shape shape.Thereby, can for example be screwed to securely housing 13 by box spanner by attached 10 with plain mode.This means, attached 10 is fixed on valve 1 in door actuator, and bolt portion 15 makes valve can be suitable for door actuator together with lining 2, as described above.As further seen in Fig. 1 to Fig. 3, bolt portion 10f transversely has an external dimensions larger than the external dimensions of male screw portion 10e longitudinal axis L.Thereby, form abutting part, bolt portion 10f can not be moved in the negative thread part 13c of housing 13 too much, thereby attached 10 can not move in housing 13 too much.In addition, because only needing to be tightened, this bolt portion needn't consider any size, so bolt portion 10f has simplified installation.

Fig. 4 shown according to the valve 1 of second embodiment of the invention with the similar sectional view of Fig. 1 to Fig. 3.This valve is different from embodiment above substantially due to the back-moving spring 4 of difference layout.Spring with pre-tensioned state in the direction away from bolt portion 15 along the longitudinal movable paths arrangement of valve body 3 in the space 25 between valve body 3, lining 2 and bolt portion 15.This means, back-moving spring 4 is same by valve body 3, its stop surface 5 is pressed against the opposite edges 6 of lining 2.This means, spring fitting 17 and recess 2a and 3a can be removed.Therefore, valve body 3 and lining 2 can be configured to shortly more remarkable than the variation of describing before.The remainder of valve 1 is constructed according to above-described embodiment.For example, Fig. 4 has shown the structure according to Fig. 3.
