Tramp material is caught and to be reduced with the pressure loss of the pressure loss of filter element 21,24 and a plurality of dispersion intercommunicating pore 26 all (aggregate value) littler than the pressure loss of throttling passage member 23 with filter element 20 and the fluid sound that flows.Like this, correctly set the throttle degree (amount of restriction) of throttle valve gear 10 according to the basal area of the throttling passage 22 that is formed at throttling passage member 23.
Below, the action of the throttle valve gear 10 of above-mentioned formation is described.
Under the state of o device 30 not being switched on, spring force by the compression helical spring 37 of o device 30 lifts valve body 17 with plunger 32 and leaves from seat portion 16, obtains to open fully the valve state of opening that does not have throttling action in fact of the standard-sized sheet of valve opening 15.
When to 30 energisings of o device, the elastic force of resistance compression helical spring 37 is attracted to plunger 32 with magnetic force the 35A of hypopleurite portion one side of outer container 35, drive valve body 17 towards closing the valve direction, as shown in Figure 1, valve body 17 is seated to seat portion 16 with front end outer peripheral face 17A.
Close under the valve state at this, catch with filter element 20 by tramp material, disperse intercommunicating pore 26, the mobile sound of fluid reduces with filter element 21, the throttling passage 22 of throttling passage member 23, the mobile sound of fluid reduces with filter element 24, valve opening 15 is communicated with valve chamber 14 and the 2nd flow hole 13, the 1st flow hole 12 is the high-pressure side, the 2nd flow hole 13 is a low-pressure side, at this moment, catch with filter element 20 → dispersions intercommunicating pore 26 → fluid sound that flows by tramp material and reduce the reduction of flowing of throttling passage 22 → fluid with filter element 21 → throttling passage member 23 and make fluid such as cold-producing medium mobile with the order of filter element 24.
When fluid flows as described above, at first, catch the seizure of carrying out the pollutant of fluid in mobile with filter element 20 by the big tramp material of surface area cylindraceous, simultaneously, carry out the refinement of the bubble (gas grain) in the liquid stream, then, fluid by a plurality of dispersion intercommunicating pores 26 respectively disperse flow in flow into the fluid sound that flows and reduce with filter element 21, reduce throttling passage 22, fluid with filter element 21, throttling passage member 23 sound that flows and reduce by the fluid sound that flows successively with filter element 24.Like this, can obtain needed restriction effect, obtain rectification by the mobile sound reduction of the fluid of its front and back with filter element 21,24 and turn usefulness into, turn into making fluid reduce the raising quietness for mobile by rectification by throttling passage 22.
In addition, owing to catch with the pollutant in the filter element 20 seizure fluid streams with tramp material, so, even long-term the use yet can not obtain stable effect in blocking pollution thing ground in throttling passage 22, since tramp material catch with filter element 20 be cylindric, surface area is big, so,, can stand long-term use for the mesh blocking problem.
When the fluid that flows in catching with filter element 20 at tramp material is gas liquid mixture, catch by tramp material and to pass through to make gas grain refinement in the gas-liquid mixture fluid with filter element 20, the flow velocity resistance ratios liquid of the gas grain after the refinement is big, be easy to be stuck in top by buoyancy function, in the stagnation process gas grain again in conjunction with making it be easy to become big, produce noise (creak creak) by the just swelling fracture at the intermittence by the gas grain behind the throttle orifice.
At this point, catch from tramp material by making that with filter element 20 fluid to be guided to the fluid sound reduction of flowing be the dispersion intercommunicating pore 26 that is dispersed into a plurality of minor diameters with the passage of filter element 21, throttling passage member 23, each disperses intercommunicating pore 26 not to be big channel space, so, do not disperse intercommunicating pore 26 to be detained gas grain, the not alligatoring of gas grain at each.Like this, can avoid just the swelling fracture at the intermittence by the gas grain behind the throttle orifice to produce noise, further improve quietness.
In addition,, there is not such large space of the gas grain alligatoring in the gas-liquid mixture fluid in the upper portion of valve chamber 14 because the external diameter that tramp material is caught with filter element 20 equates substantially with the external diameter of plunger 32, so, be not detained the gas grain in the upper portion of valve chamber 14.Also can prevent the alligatoring of gas grain thus, avoid producing noise, further improve quietness by the just swelling fracture at the intermittence by the gas grain behind the throttle orifice.
Fig. 6 illustrates the form of implementation 2 of throttle valve gear 10 of the present invention.In Fig. 6, the part corresponding with Fig. 1 has the identical symbol of symbol that adopts with Fig. 1, omits its explanation.
In this form of implementation, the downstream installation that reduces with filter element 24 at the mobile sound of the fluid in throttling passage member 23 downstreams has the dispersion injection member 28 (with reference to Fig. 7) of a plurality of spray-holes 27.
When for dispersion injection member 28, owing to spray fluid respectively from a plurality of spray-holes 27, so, compare with the occasion of single hole, reduce the flow path length increase of using the fluid that flows in the filter element 24 at the mobile sound of fluid, the fluid availability that sound reduces with filter element 24 that flows increases, and in addition, can obtain the effect that shock wave is cancelled out each other by the mutual interference of the injection stream of the spray-hole 27 of adjacency.Like this, can further improve quietness.
In addition, in this form of implementation 2, be provided with at all grooves 19 of valve body 17 peripheral parts and be used for catching inner peripheral surface and the recess 19A that disperses formation minim gap between the intercommunicating pore 26 with filter element 20 at tramp material.
By this recess 19A being set to all grooves 19 of valve body 17 peripheral parts, disperse intercommunicating pore 26 and tramp material to catch to have minim gap ground with filter element 20 to be communicated with thereby make, the flow velocity of the cold-producing medium by dispersion intercommunicating pore 26 can be owing to the existence maximum can be slowed down with filter element 20 by these dispersion intercommunicating pore 26 low tramp materials seizure of flow-rate ratio.
Therefore, even the solid shape tramp material that is called as pollutant that is blended in the cold-producing medium is attached to the inwall that disperses intercommunicating pore 26, flow velocity also be can't help tramp material and is caught and to reduce with filter element 20, can prevent from actually disperseing intercommunicating pore 26 inwalls to adhere to by the force and velocity of a current of the cold-producing medium by disperseing intercommunicating pore 26 like this, can prevent to disperse the mesh of intercommunicating pore 26 to stop up.
The recess 19A of all grooves 19 of above-mentioned valve body 17 peripheral parts also can similarly be located in the throttle valve gear 10 of form of implementation shown in Figure 1, on the contrary, the recess 19A of all grooves 19 of valve body 17 peripheral parts that are provided with in the throttle valve gear 10 of the form of implementation 2 that is shown in Fig. 6 is not as there being special problem, then also as shown in Figure 1 the throttle valve gear 10 of form of implementation omit like that.
