In the present embodiment, because the end of filter component 5a, 5b is positioned at identical position with the end of first protuberance 7a, 7b, therefore the bottom surface of first recess 10a, 10b is exposed to the bottom of groove 2a, 2b throughout the roughly whole region of the width of groove 2a, 2b, only have the part of the edge near the side contrary with first recess 10a, 10b more outstanding to the surface side of sleeve 1 than the bottom surface 101 of first recess 10a, 10b in groove 2a, 2b, this is partly arranged at the inner side of notch part 9a, 9b.
As shown in Figure 6, recess 10a, 11a of being arranged at the first groove 2a and recess 10b, 11b of being arranged at the second groove 2b are positioned at the position circumferentially rotating 180 °.Being arranged at first recess 10a, 10b of groove 2a, 2b and second recess 11a, 11b is the symmetrical shape of centre line L 0 across extending along the diametric(al) of sleeve 1.The bottom surface 111 being arranged at the bottom surface 101 of the first recess 10a of the first groove 2a and the second recess 11a is in the same plane.One end of one end of the bottom surface 101 of the first recess 10a and the bottom surface 111 of the second recess 11a arrives the outer circumferential face of sleeve 1.Similarly, as this is shown in phantom in fig. 6, the bottom surface 111 being arranged at the bottom surface 101 of the first recess 10b of the second groove 2b and the second recess 11b is in the same plane.One end of one end of the bottom surface 101 of the first recess 10b and the bottom surface 111 of the second recess 11b arrives the outer circumferential face of sleeve 1.
The end of the inner side of sleeve 1 of leaning on of the bottom surface 101 of first recess 10a, 10b and the bottom surface 111 of second recess 11a, 11b is provided with the wall 102,112 generally perpendicularly erected from each bottom surface 101,111.Wall 102,112 is arranged in the mode of intersecting with the circumference of sleeve 1, and wall 102 engages with the edge of first protuberance 7a, 7b, and wall 112 engages with the edge of second protuberance 8a, 8b.The part of the outer circumferential side by sleeve 1 of wall 102,112 is more outstanding obliquely to the inner side of each recess than the part by side, bottom surface 101,111.
The degree of depth D1 of first recess 10a, 10b and second recess 11a, 11b is darker than the degree of depth D2 of each groove 2a, 2b, and bottom surface 101,111 is formed to the position darker than the surface of the distance from bottom sleeve 1 of groove 2a, 2b.
As shown in Figure 7, the angle part between the bottom surface 101 and wall 102 of first recess 10a, 10b is provided with the plane of inclination 103 of surface curvature.The boundary position P1 of plane of inclination 103 and bottom surface 101 to the outermost radial outside of wall 102 bight P2 between distance be exactly the degree of depth D1 of first recess 10a, 10b.Although the angle between the bottom surface 101 of first recess 10a, 10b and wall 102 is less than 90 °, the straight line connecting the bight P2 of plane of inclination 103 and the boundary position P1 of bottom surface 101 and the outermost radial outside of wall 102 also can be more than 90 ° with the angle [alpha] between bottom surface 101.In addition, identical plane of inclination 103 also can be set in second recess 11a, 11b and be greater than the angle of 90 °.Further, the degree of depth D1 of the wall 102 of first recess 10a, 10b is larger than the circumferential lengths L1 of first protuberance 7a, 7b.
As shown in Figure 8, circumferential distance Q1 between first protuberance 7a, 7b and second protuberance 8a, 8b is longer than diagonal distance Q2, described diagonal distance Q2 is the distance between the wall 112 of the bottom surface 101 of first recess 10a, 10b and boundary position to the second recess 11a, 11b of wall 102 and the boundary position P4 of sleeve outer surface, namely, in the present embodiment with bending plane of inclination 103, described diagonal distance Q2 is the distance between the wall 112 of boundary position P3 to the second recess 11a, 11b of plane of inclination 103 and wall 102 and the boundary position P4 of sleeve outer surface.
As long as the circumferential distance Q1 between first protuberance 7a, 7b and second protuberance 8a, 8b is larger than the circumferential distance Q3 between first recess 10a, 10b and second recess 11a, 11b, then when making the side face of filter component 5a, 5b and sleeve 1 move abreast, first protuberance 7a, 7b and second protuberance 8a, 8b just can enter in first recess 10a, 10b and second recess 11a, 11b respectively.But when carrying out as installed operation, owing to being inserted in groove 2a, 2b by filter component 5a, 5b of C font with the state overcoming elasticity and open laterally, therefore filter component 5a, 5b moves obliquely relative to the side face of sleeve 1.Therefore, only by the circumferential distance Q1 this point longer than the circumferential distance Q3 between recess between protuberance, be difficult to install, if the circumferential distance Q1 between protuberance is less than or equal to the diagonal distance Q2 between recess, then cannot successfully mounting filter parts.In the present embodiment, even if filter component 5a, 5b are relative to all face tilts of sleeve 1, also two protuberances can be installed in each recess.
As shown in Figure 3, first recess 10a, 10b circumferential lengths N1 than the circumference of one end to the second protuberance 8a, 8b of the circumference of first protuberance 7a, 7b the other end between distance M short.Similarly, the circumferential lengths N2 of second recess 11a, 11b also than the circumference of one end to the second protuberance 8a, 8b of the circumference of first protuberance 7a, 7b the other end between distance M short.Namely, this is in order to avoid following mistake is installed: if the circumferential lengths N1 of each recess, N2 are large and distance M between the other end of the circumference of one end to the second protuberance 8a, 8b of the circumference of first protuberance 7a, 7b is little, then when mounting filter parts 5a, 5b, both the first protuberance and the second protuberance enter in any one recess.
The circumferential lengths L1 of first protuberance 7a, 7b is less than the circumferential lengths L2 of second protuberance 8a, 8b, the circumferential lengths N1 of first recess 10a, 10b is less than the circumferential lengths N2 of second recess 11a, 11b, and therefore second protuberance 8a, 8b cannot be contained in first recess 10a, 10b.If suppose, second protuberance 8a, 8b can be contained in the size in first recess 10a, 10b, then when second protuberance 8a, 8b being embedded in first recess 10a, 10b because of faulty operation, because second protuberance 8a, 8b engages with the wall 102 of first recess 10a, 10b, therefore, it is possible to filter component 5a, 5b are installed in groove 2a, 2b.But, because second protuberance 8a, 8b does not engage with second recess 11a, 11b, therefore cannot play the function of spline, thus filter component 5a, 5b easily come off.
In the present embodiment, sleeve 1 and each recess 10a-11a being arranged at sleeve 1 are made up of cast member, and the first groove 2a and the second groove 2b is by making the all-round cutting of carrying out of the sleeve 1 as cast member.
[1.2 effect]
In the filter installation structure of present embodiment with this structure, first as shown in the sectional view of Fig. 3, Split mold is utilized to form groove 2a, 2b and recess 10a, 10b, 11a, 11b at sleeve 1.Now, even if the wall of each recess 10a, 10b, 11a, 11b 102,112 is in skewed, also by being become by the segmentation direction setting of mould and the bottom surface 101 of recess 10a, 10b, 11a, 11b, 111 parallel, avoid the molding operation of plane of inclination obstruction mould.Afterwards, sleeve 1 is rotated centered by its axis, while utilize lathe to carry out cutting to two grooves 2a, 2b, thus the shape of these two grooves 2a, 2b is become the precision of regulation with surface Machining.
In order to after valve body etc. being assembled in the sleeve 1 so obtained, filter component 5a, 5b are installed on a part of groove 2a, 2b, by filter component 5a, 5b of C shape first protuberance 7a, 7b is separately embedded in first recess 10a, 10b, and second protuberance 8a, 8b is embedded in second recess 11a, 11b, opening R2 shown in Fig. 4 is contacted, from filter component 5a, 5b of top pressing C shape with groove 2a, 2b along groove 2a, 2b.Thus, filter component 5a, 5b expand because of the elasticity of this filter component, while slide, in embedded groove 2a, 2b at the side face of groove 2a, 2b.Consequently, covered by the filtration fraction comprising multiple through hole 6a, 6b in filter parts 5a, 5b at port 3a, 3b of the bottom opening of groove 2a, 2b, filter component 5a, 5b are fixed to by each recess 10a, 10b, 11a, 11b can not move up in the week of sleeve 1 with the engagings of each protuberance 7a, 7b, 8a, 8b.
Now, the wall 102 of first recess 10a, the 10b engaged with first protuberance 7a, 7b and the wall 112 of second recess 11a, 11b engaged with second protuberance 8a, 8b engage from opposition side with each lock part in the circumference of sleeve 1.Therefore, filter component 5a, 5b can not move on which direction positive and negative of the circumference of sleeve 1.Further, it is skewed that the part due to the side face side of wall 102,112 in sleeve 1 of each recess 10a, 10b, 11a, 11b is given prominence to, and therefore prevents first protuberance 7a, the 7b be embedded in first recess 10a, 10b to tilt.Consequently, even if apply vibration to control valve unit or impact, the bottom of filter component 5a, 5b and groove 2a, 2b also can be reliably close to.
When filter component 5a, 5b are installed on two grooves 2a, 2b respectively, are arranged at the first recess 10a of the first groove 2a and the second recess 11a and are arranged at the first recess 10b of the second groove 2b and the second recess 11b and be positioned at axis across sleeve 1 and rotational symmetric position.Therefore, by filter component 5a, 5b of same shape be inverted to the first protuberance 7a of its end and the second protuberance 8a or the first protuberance 7b and the second protuberance 8b relative to axially become rightabout state and be installed in two grooves 2a, 2b any one, make being engaged by lock part of the lock part of filter component 5a, 5b and its groove 2a, 2b.
[1.3 effect]
The effect had as the present embodiment of said structure is as follows.
(1) first protuberance 7a, 7b owing to being arranged at filter component 5a, 5b gives prominence to than the width of groove 2a, 2b, and therefore first protuberance 7a, 7b of belt filter can not enter in the part not forming first recess 10a, 10b of groove 2a, 2b.Therefore, it is possible to carry out correct location to first protuberance 7a, 7b of belt filter and first recess 10a, 10b of groove 2a, 2b, and reliably can be covered the open part of port 3a, 3b that sleeve 1 is arranged by through hole 6a, 6b.
(2) owing to being set to what be arranged at groove 2a, 2b first recess 10a, the 10b expanded vertically from the edge of groove 2a, 2b by lock part, therefore can not be formed obstruction when carrying out cutting to groove 2a, 2b by lock part, thus around sleeve 1, groove 2a, 2b of ring-type can be formed simply.
(3) because the position of first recess 10a, the 10b being arranged to groove 2a, 2b of two row is positioned at the side contrary with adjacent groove 2a, 2b, even if therefore when the interval of port 3a, 3b of being arranged at sleeve 1 is little, first recess 10a, the 10b being arranged at groove 2a, 2b also can not produce obstruction, closely can configure two ports 3a, 3b.Further, due to adjacent groove 2a, 2b first recess 10a, 10b between mutual noninterference, therefore can also arrange and reliably engage so large-sized first recess 10a, 10b with filter component 5a, 5b.
(4) first recess 10a, 10b owing to being arranged at two grooves 2a, 2b is positioned at axis across sleeve 1 and rotational symmetric position, therefore, it is possible to by filter component 5a, 5b of same shape with the lock part being inverted to its end relative to axially becoming any one that rightabout state is installed in two grooves 2a, 2b.Consequently, even if the direction forming first recess 10a, 10b is different in two grooves 2a, 2b, filter component 5a, 5b of same shape can also be used, without the need to preparing special filter component 5a, 5b by each groove 2a, 2b.
(5) owing to making two of filter component 5a, 5b first protuberances 7a, 7b engage with two first recesses 10a, 10b of groove 2a, 2b, therefore become and utilize two first protuberances 7a, 7b to clamp the state of the wall between two first recesses 10a, 10b.Therefore, filter component 5a, 5b are engaged on which direction of the circumferential lengths of groove 2a, 2b, can reliably position filter component 5a, 5b.
(6) its bottom surface 101 and bottom surface 111 are disposed on the same plane by the first recess 10a and the second adjacent recess 11a owing to being arranged at sleeve 1, and its bottom surface 101 and bottom surface 111 are disposed on the same plane by the first recess 10b and the second adjacent recess 11b, and the bottom surface 101 of the first recess 10a and the bottom surface 111 of the second recess 11a are extended to the outer circumferential face of sleeve 1, therefore, when casting sleeve 1, the first recess 10a and the second recess 11a can not become the obstruction on the number of unmolulding directions of Split mold.Consequently, without the need to using complicated mould, utilize cast member to manufacture to have the sleeve 1 of the first recess 10a and the second recess 11a.
(7) because the wall of first recess 10a, 10b is skewed, therefore, when being embedded in first recess 10a, 10b from the upper opening portion of first recess 10a, 10b by first protuberance 7a, 7b of filter component 5a, 5b, the edge of first protuberance 7a, 7b engages and difficult drop-off with plane of inclination.Consequently, can prevent filter component 5a, 5b in groove 2a, 2b position skew or filter component 5a, 5b come off from sleeve 1.Especially due to the wall of two first recesses 10a, 10b is set as skewed respectively, therefore no matter filter component 5a, 5b towards which direction of the circumferential lengths of groove 2a, 2b rotates, a protuberance of two first protuberances 7a, 7b is all inevitable to be engaged with skewed wall, thus can prevent first protuberance 7a, 7b from tilting from the bottom surface 101 of first recess 10a, 10b.
(8) due to be made up of sleeve 1 cast member and be arranged at sleeve 1 by lock part, and form groove 2a, 2b by carrying out cutting to the sleeve 1 as cast member, therefore, it is possible to manufacture sleeve 1 itself simply, and the dimensional accuracy on the surface of groove 2a, 2b of mounting filter parts 5a, 5b and smoothness high.Therefore, when mounting filter parts 5a, 5b, filter component 5a, 5b can be made to slide simply along the surface of groove 2a, 2b and embed, improve workability, and the close property on filter component 5a, 5b and groove 2a, 2b surface is high, can prevent foreign matter from entering in valve from filter component 5a, 5b and the gap between groove 2a, 2b, or mounted filter component 5a, 5b come off from groove 2a, 2b.
(9) owing to being provided with notch part 9a, 9b of the width direction depression making the bight of the side contrary with lock part towards band in the end being provided with lock part of filter component 5a, 5b, therefore first recess 10a, 10b without the need to the side by being formed at groove 2a, 2b is arranged throughout the whole width of groove 2a, 2b, can in the bottom of side reserved slit 2a, the 2b contrary with first recess 10a, 10b.Consequently, first recess 10a, 10b can be deeper formed than the surface of groove 2a, 2b distance sleeve 1, the mesh volume of first recess 10a, 10b and first protuberance 7a, 7b can be increased, thus filter component 5a, 5b reliably can be fixed on groove 2a, 2b.
(10) when the filter component of C font is installed on columnar sleeve with winding method, the load that comes off when filter component comes off from sleeve is according to the material of filter component, the condition such as wall thickness and elasticity coefficient and different.If make these conditions fix, then the load that comes off described in depends on the circumferential angle of filter component cover sleeve.If circumferential angle is less than 250 °, even if then adjust other conditions, be also difficult to obtain the necessary load that comes off.If circumferential angle is more than 360 °, then the two ends of filter component are overlapping in groove, produce gap and cause foreign matter to enter at this lap, or are also difficult to the installation exercise that carries out being installed to by filter component in groove.
In the present embodiment, because filter component 5a, 5b of C font is circumferentially less than the scope cover sleeve 1 of 360 ° with more than 250 ° in groove 2a, 2b, therefore form filter component 5a, 5b and surround the shape of encircling sleeve 1 from surrounding, filter component 5a, 5b are by elasticity reliably and be stably close to the bottom of groove 2a, 2b.Consequently, even if when applying the vibration from outside to control valve unit or the inner side from sleeve 1 applies hydraulic pressure to filter component 5a, 5b, also can reliably prevent filter component 5a, 5b from coming off from groove 2a, 2b.
(11) due to dark by the degree of depth of depth ratio groove 2a, 2b of first recess 10a, 10b of lock part as first, therefore, it is possible to increase the height of the wall 102 making first protuberance 7a, 7b as the first lock part block.Consequently, first protuberance 7a, 7b and first recess 10a, 10b can be made reliably to block, and filter component 5a, 5b circumferentially can not offset in groove 2a, 2b, position exactly to filter component 5a, 5b.That is, if first recess 10a, 10b is shallow, then when carrying out the installation exercise of filter component, first protuberance 7a, 7b and first recess 10a, 10b easily comes off, and workability is poor, but eliminates this problem in the present embodiment.
(12) larger than the width X comprised as first protuberance 7a, 7b of lock part and the end of second protuberance 8a, 8b of filter component 5a, 5b by the width Y of first recess 10a, 10b of lock part and second recess 11a, 11b due to as present embodiment, therefore block deeper by lock part and lock part, make both reliably engage.If suppose, width Y is less than width X, then protuberance is blocked in the bottom of groove 2a, 2b, can not contact with the bottom surface 101,111 of recess.Consequently, the quantitative change blocked by lock part and lock part is few, is easily come off by lock part and lock part.
(13) when filter component 5a, 5b are installed in groove 2a, 2b, the end of first protuberance 7a, 7b is vertically pressed relative to the bottom surface 101 of first recess 10a, 10b, the inner side of first protuberance 7a, 7b is made to be stuck on wall 102, if but now the circumferential lengths L1 of first protuberance 7a, 7b is longer than the degree of depth D1 of first recess 10a, 10b, then the inner side of first protuberance 7a, 7b is positioned at the position higher than wall 102, is difficult to first protuberance 7a, 7b to be stuck on wall 102.In the present embodiment, it is darker than the circumferential lengths L1 of first protuberance 7a, 7b due to the degree of depth D1 of first recess 10a, 10b is set as, as long as therefore by the end of first protuberance 7a, 7b by the state being pressed in bottom surface 101 under open filter component 5a, 5b of C font, in position in the inner part, the ratio upper end that the inner side of first protuberance 7a, 7b just can be made to enter wall 102, thus the inner side of first protuberance 7a, 7b is engaged swimmingly with wall 102.
The bottom surface 101,111 of (14) first recess 10a, 10b and second recess 11a, 11b is formed to the position darker than the surface of the distance from bottom sleeve 1 of groove 2a, 2b.In the present embodiment, due to the position consistency of the end of the position and first protuberance 7a, 7b that make the end of filter component 5a, 5b, therefore, when the end of filter component 5a, 5b being pressed on bottom surface 101 of first recess 10a, 10b, first protuberance 7a, 7b can be made to engage simply with the wall 102 of first recess 10a, 10b.And, because the bottom surface of first recess 10a, 10b to be exposed to the bottom of groove 2a, 2b throughout the roughly whole region of the width of groove 2a, 2b, therefore by the end of filter component 5a, 5b is inserted into this part exposed, the engaging amount of first protuberance 7a, 7b and wall 102 can be increased, thus the elastic force of C font can be overcome and filter component 5a, 5b brute force is pressed on groove.Now, only have the part of the edge near the side contrary with first recess 10a, 10b more outstanding to the surface side of sleeve 1 than the bottom surface 101 of first recess 10a, 10b in groove 2a, 2b, but by arranging notch part 9a, 9b at filter component 5a, 5b, the end of filter component 5a, 5b can be avoided projection and being pressed in first recess 10a, 10b.
(15) owing to being provided with the plane of inclination 103 of surface curvature at the wall 102 of first recess 10a, 10b and the angle part of bottom surface 101, therefore when mounting filter parts 5a, 5b, first, the end of first protuberance 7a, 7b is while slide in bottom surface 101, while move towards the direction leaving wall 102, with this, the edge of the inner side of first protuberance 7a, 7b is along the surface sliding of wall 102 while decline.Because the lower end of plane of inclination 103 with wall 102 is arranged continuously, therefore the edge of the inner side of first protuberance 7a, 7b is moved along plane of inclination by filter component 5a, 5b are pressed on the active force from top in groove.Consequently, first protuberance 7a, 7b entirety is pressed by the direction leaving wall 102, and therefore the end of first protuberance 7a, 7b can slide like a cork on bottom surface 101, thus filter component 5a, 5b can be made easily to be close to the bottom of groove 2a, 2b.
(16) when by the straight line of the plane of inclination 103 of connection first recess 10a, 10b and the bight P2 of the boundary position P1 of bottom surface 101 and the outermost radial outside of wall 102 with the angle [alpha] between bottom surface 101 be set as be greater than 90 °, the opening of first recess 10a, 10b becomes large, first protuberance 7a, 7b can be inserted in first recess 10a, 10b simply, improve workability.
