Oil-feed closure part 212a roughly is in same cross section with each oil-feed runner, and oil-feed closure part 212a coordinates with mounting hole 23 inwalls, and when switching shaft 21 rotated vertically, oil-feed closure part 212a can the arbitrary oil-feed runner of shutoff and being communicated with of oil suction chamber 231.Certainly, it is also feasible that each oil-feed runner is not in same cross section, and this moment, oil-feed closure part 212a needed to lengthen, so that rotation angle is when changing, and can each oil-feed runner of shutoff.Obviously, each oil-feed runner is in same cross section and makes total more compact.
In Fig. 8,10, three oil-feed runners are followed successively by the first oil-feed runner 2c, the second oil-feed runner 2d, the 3rd oil-feed runner 2e from left to right, oil-feed closure part 212a rotates with the rotational synchronization of switching shaft 21, inwall along mounting hole 23 slides, oil-feed closure part 212a turns to interface position with the first oil-feed runner 2c at once, can block the first oil-feed runner 2c.Suppose that the switching shaft 21 in Fig. 8 rotates counterclockwise, oil-feed closure part 212a can be from left to right shutoff the first oil-feed runner 2c (Figure 10), the second oil-feed runner 2d, the 3rd oil-feed runner 2e successively so that change with by filter cylinder 3 corresponding to the oil-feed runner of shutoff.When switching shaft 21 was in Fig. 8 state, oil-feed closure part 212a was all not corresponding with all oil-feed runners positions, and all oil-feed runners all can be communicated with all normal oil-feeds of 231, three filter cylinders 3 of oil suction chamber.
This embodiment only arranges an oil suction chamber 231, and during rotating shaft, its oil-feed closure part 212a can be with the arbitrary oil-feed runner of the variation shutoff of rotation angle.And the switching shaft 21 in background technique needs to arrange plugging part, the oil-feed cavity corresponding with filter cylinder 3 numbers, as seen, this example has been simplified the structure of switching shaft 21, thereby has further simplified filter seat 2, when being provided with a plurality of filter cylinder 3, still be of compact construction, less volume.It is also feasible that as stated in the Background Art the mode of being appreciated that designs switching shaft 21.
Can form in the following manner above-mentioned oil suction chamber 231:
As shown in Fig. 4-7, be axially arranged with the first annular protrusion 211 and the second annular protrusion 213 along switching shaft 21, two annular protrusions all coordinate with the inner wall sealing of mounting hole 23, in this embodiment, the periphery wall of the first annular protrusion 211 and the second annular protrusion 213 is equipped with circular groove, to put seal ring, guarantee the sealing effect with mounting hole 23 inwalls.Switching shaft 21 parts between the first annular protrusion 211 and the second annular protrusion 213 form oil suction chamber section 212, has the gap between oil suction chamber section 212 and mounting hole 23 inwalls to form oil suction chamber 231, as shown in Figure 5, at this moment, oil-feed closure part 212a is formed at the outer wall of oil suction chamber section 212, and oil-feed closure part 212a is roughly concordant with the periphery wall of annular protrusion.According to this mode, switching shaft 21 inserts in mounting hole 23 and can form oil suction chamber 231, and processing is simple.At this moment, each oil-feed runner of filter seat 2 processing is communicated to mounting hole 23 places of oil suction chamber section 212 correspondences.
On this basis, also can form between switching shaft 21 and mounting hole 23 and be communicated with total return opening 2b and the oil back chamber 232 isolated with oil suction chamber 231, as shown in 7,9.Each oil return runner all is communicated with total return opening 2b by oil back chamber 232.
At this moment, the part outer wall of switching shaft 21 can form oil return closure part 214a, when switching shaft 21 rotated, oil-feed closure part 212a can the arbitrary oil-feed runner of shutoff and being communicated with of oil suction chamber 231, while oil return closure part 214a can shutoff with by oil return runner corresponding to the oil-feed runner of shutoff.Be that switching shaft 21 rotates so that oil-feed closure part 212a when blocking an oil-feed runner, the oil return closure part 214a of switching shaft 21 rotates same angle and correspondingly blocks the oil return runner corresponding with this oil-feed runner, and the stream of the import of filter cylinder 3, outlet and filter seat 2 all is truncated.
As shown in figure 11, three oil return runners are followed successively by the first oil return runner 2f, the second oil return runner 2g, the 3rd oil return runner 2h from left to right, oil return closure part 214a rotates with the rotational synchronization of switching shaft 21, inwall along mounting hole 23 slides, oil return closure part 214a turns to interface position with the first oil return runner 2f at once, can block the first oil return runner 2f.Suppose that the switching shaft 21 in Fig. 9 rotates counterclockwise, oil return closure part 214a can be from left to right shutoff the first oil return runner 2f (Figure 11), the second oil return runner 2g, the 3rd oil return runner 2h successively.When switching shaft 21 was in Fig. 9 state, oil return closure part 214a was all not corresponding with all oil return runners positions, and all oil return runners all can be communicated with all normal oil returns of 231, three filter cylinders 3 of oil suction chamber.
During design, oil return closure part 214a and oil-feed closure part 212a can be positioned at same straight line, this straight line is parallel with axis, correspondingly, the interface of oil-feed runner, oil return runner and mounting hole 23 also is in same straight line, when switching shaft 21 rotates, can guarantee to block simultaneously a pair of oil-feed runner and oil return runner.Certainly, it is also feasible that the position of oil return closure part 214a and oil-feed closure part 212a is designed not according to this mode, as long as a pair of oil-feed runner, oil return runner are made corresponding shift in position.
When changing filter cylinder 3, block simultaneously the oil return runner of correspondence on filter seat 2, can guarantee all normal oil returns of energy of fluid after other filter cylinders 3 filter, prevent the oil return leakage.In addition, with above-mentioned oil suction chamber 231 that effect is set is similar, so design oil back chamber 232, also make switching shaft 21 that a plugging part only is set and can realize that structure is simplified to the shutoff of arbitrary oil return runner.
The generation type of the generation type of oil back chamber 232 and oil suction chamber 231 is similar.Please continue the 4-7 with reference to figure, axial the 3rd annular protrusion 215 that coordinates with the inner wall sealing of mounting hole 23 that also is provided with along switching shaft 21, the 3rd annular protrusion 215 and the second adjacent setting of annular protrusion 213, switching shaft 21 parts between the second annular protrusion 213 and the 3rd annular protrusion 215 form oil back chamber section 214, have the gap between oil back chamber section 214 and mounting hole 23 inwalls and form oil back chamber 232, oil return closure part 214a is formed at the outer wall of oil back chamber section 214.At this moment, oil return closure part 214a is also roughly concordant with the periphery wall of annular protrusion.
From Fig. 7, after switching shaft 21 plug-in mountings enter mounting hole 23, from top to bottom form successively by oil suction chamber 231 and the oil back chamber 232 of the second annular protrusion 213 isolation.So design, separately establish the 3rd annular protrusion 215, can form oil back chamber 232, utilized the second annular protrusion 213 that forms oil suction chamber 231, processing is simple, be convenient to the layout optimization of oil-feed closure part 212a and oil return closure part 214a, the size of oil suction chamber 231 and oil back chamber 232 is also unified, and is conducive to that filter cleaner advances, the stability of oil return.
In above-described embodiment, the oil suction chamber section 212 of switching shaft 21 and the cross section of oil back chamber section 214 are quadrilateral, wherein, on one side corresponding to oil-feed closure part 212a or oil return closure part 214a, and be the arc suitable with mounting hole 23 inwalls, in Fig. 8,9, with the corresponding oil-feed of arc-shaped side difference closure part 212a, the oil return closure part 214a of mounting hole 23 inwalls applyings; Another three limits and mounting hole 23 inwalls have the gap, to form oil suction chamber 231 or oil back chamber 232.The oil-feed closure part 212a of arc or oil return closure part 214a can block corresponding oil-feed runner or oil return runner preferably, and it is mild to slide, and weares and teares less, in the rotation process of switching shaft 21, the constancy of volume of oil suction chamber 231 or oil back chamber 232, avoid to advance, oil return causes interference.
Be appreciated that oil return closure part 214a and oil-feed closure part 212a are not limited to the above-mentioned arc design adaptive with mounting hole 23 inwalls.It is also feasible that shape both is spherical, and just the shutoff wall of this shape is when shutoff oil-feed runner or oil return runner, and in rotation process, frictional force is larger, and in long-term using process, the sealing of shutoff can reduce, and sealing effect will be inferior to above-mentioned arc design.
For above-described embodiment, filter seat 2 also can arrange relief hole 24, and relief hole 24 is connected with atmosphere, has buck functionality.Filter seat 2 is provided with pressure Control Shaft 22, and pressure Control Shaft 22 is plugged in switching shaft 21, and as shown in Fig. 3,7, switching shaft 21 has hollow cavity.
