Abstract
Description
- The present invention refers to a motor pump of the hydraulic-electromagnetic type with floating piston.
- More particularly, the present invention refers to a motor pump of the hydraulic-electromagnetic type with floating piston, particularly suitable for the use in the fluid motion, especially water.
- This type of motor pumps is applied to various apparatuses such as irons, electric coffee percolators, irrigation systems and also in the automotive industry.
- Motor pumps of the hydraulic-electromagnetic type with floating piston are known from EP-A-1 205 663, US-A-4 749 343, EP-A-1 001 167 and EP-A-0 288 216. Particularly, EP-A-1 205 663 discloses a motor pump of the hydraulic-electromagnetic type with floating piston having the features of the preamble of claim 1.
- The operation of said motor pumps is based on the presence of a coil that cooperates with a couple of magnetic bearings; the coil is electrically powered and causes the axial movement of the floating piston or delivery piston with an alternate motion. The coil is placed outside the body of the motor pump, while the magnetic bearings are positioned in an annular seat formed between the same coil and a sleeve housing said piston. Said piston is elastically supported by opposite helical springs that are alternatively compressed during the floating in order to allow the passage of the fluid from the inlet duct to the delivery one. Known valves, rings and rubber gaskets associated to the piston and to the relevant sleeve assure the seal of the fluid moving inside the body of the motor pump.
- These motor pumps have an important drawback that is essentially related to the pressure level that can be obtained, considering that sometimes, for particular uses, a high fluid pressurization is required. It is known that an increase in fluid pressurization can be obtained increasing the intensity of the magnetic field by the oversizing of the coil. This implies an unavoidable increase of the motor pump dimensions and a considerable additional cost due to the increase of the winding coils. A greater size of the body of the motor pump in its whole sometimes is not compatible with the installation of the motor pump on the target apparatus or it requires at least structural changes of the same apparatus. Even the increase in cost is an important factor that could lead to the manufacturing of uncompetitive products.
- Object of the present invention is to remove the above-mentioned drawbacks.
- More particularly, object of the present invention is the provision of a motor pump of the hydraulic-electromagnetic type with floating piston wherein the pressure level of the delivery fluid can be increased without oversizing the coil with a subsequent increase of its dimensions and production costs.
- A further object of the present invention is to provide a motor pump of the above-mentioned type that can guarantee a high resistance and reliability level in time and it is easily manufactured.
- According to the present invention these and other purposes are obtained by a motor pump comprising:
- a container body that is partly delimited, in its external part, by a coil;
- an inlet duct and an opposite outlet duct;
- a delivery piston that is placed inside the body and slides inside it and said piston is supported by a front helical-shaped spring and by a rear helical-shaped spring, and
- a couple of opposite magnetic bearings with a space between them and placed between said body and said coil, said couple of opposite magnetic bearings being arranged coaxially to the sliding axis of the delivery piston;
- The magnetic bearing is preferably made of steel with a low magnetic residual content.
- The manufacturing and operating features of the motor pump of the present invention will be better understood from the following description wherein reference is made to the table of the attached drawings representing a preferred embodiment given by way of non-limitative example wherein:
- Figure 1 is an exploded schematic view of the improved motor pump of the present invention;
- Figure 2 is a schematic view of a cross section of the assembled motor pump of Figure 1.
- With reference to the above-mentioned figures, the motor pump of the present invention, marked in its whole with 10 in Figure 2, comprises: an inlet duct 44'; an
opposite outlet duct 36; acontainer body 12 which is partly delimited, in its external part, by acoil 14; a couple of oppositemagnetic bearings 46, 46' that are spaced between them and placed between saidbody 12 andcoil 14; adelivery piston 16 that is placed in saidbody 12, slides in it and it is elastically supported by a common fronthelical spring 20 and by a rear one 20'. In front of saidpiston 16, in the part facing thedelivery duct 22, aseal valve 24 and apacking 26 of thedelivery piston 16 are commonly placed. Said packing 26 and saidseal valve 24 cooperate with a support bearing 28 and with arubber gasket 30 that is elastically tensioned by a furtherhelical spring 32. Saidspring 32 and partly therubber gasket 30 are housed inside aseat 34 of thedelivery duct 22 whose diameter is fit to house the ensemble formed by therubber gasket 30 and by thehelical spring 32 and it is generally higher than the one of the outlet duct orhole 36 of thedelivery duct 22. Alocking ring 38 with an internal thread engaging with a matching part that is threaded in the outer part of thecontainer body 12 is put on saidduct 22 in a known way. Said tubular-shaped container body 12, comprises afront part 40 with a higher diameter that faces theoutlet duct 36; an adjacentintermediate part 42 with a lower diameter than the one of thefront part 40 delimiting the sliding axial chamber of thepiston 16 and aterminal part 44 whose diameter is extremely lower than the one of theintermediate part 42 that defines the inlet duct 44'. - The opposite
magnetic bearings 46 and 46', that are properly spaced between them with the use of a known spacing element if necessary, are fit on the external side surface of saidintermediate part 42 of thebody 12. Thecoil 14 is in its turn fit on thebody 12 so that it can comprise saidbearings 46, 46'. Thecoil 14 is stabilized with known means that are for instance made of a shapedelastic ring 48 that matches with a face of the coil and ashoulder 50 placed on thebody 12 between thefront part 40 and the intermediate one 42 with a lower diameter that matches with the opposite face. - Inside said
container body 12 in the central-lower part facing the inlet duct 44', amagnetic bushing 52, preferably made of steel with a low magnetic residual content, is advantageously placed. The external side surface of saidmagnetic bushing 52 has differentiated diameters and defines arear area 54 that faces the duct 44' with a diameter that is equal or slightly lower than the internal one of theintermediate part 42 of thebody 12 and anadjacent front area 56 facing the outlet hole orduct 36 with a lower diameter. Saidareas matching shoulder 58 for the rear spring 20'. The lower end of themagnetic bushing 52 matches with thebody 12 in theintermediate part 42 near the narrowing of theterminal part 44 that defines the inlet duct 44'. - The axial sliding return of the
piston 16 is obtained by known means such as the couple ofhelical springs 20 and 20' previously described that cooperate with the piston. - The power of the
coil 14 is obtained, for example, by a conventional couple of electric connections of the fast-on 62 type. - The applicant has found out, by way of experiment, that the motor pump object of the present invention is highly efficient thanks to the presence of the
magnetic bushing 52 that being aligned with the sliding axis of thepiston 16 with one of its ends, it is close to the piston and therefore at a lower distance between the latter and one of the twomagnetic bushings 46, 46' when it is placed in the position reached by thepiston 16 during the loading of the rear spring 20', generally near theterminal part 44 of thebody 12. The interaction between thebushing 52 and the twobearings 46, 46' creates a magnetic field whose intensity is higher than the one of the twobearings 46, 46' only and it therefore increases the magnetic attraction force exerted on thepiston 16 and the one exerted on the fluid going out of thedelivery duct 22. - With the use of the
bushing 52, in the event of keeping the efficiency level that would be created only with the twobearings 46, 46', it is obviously possible to reduce the number of wirings of thecoil 14 with considerable production savings. The motor pump manufactured according to the above description does not imply impediments or additional costs caused by the size increase of the coil and of the relevant wiring coils, while themagnetic bushing 52 can be easily obtained and installed at a low cost. - Even though the present invention has been described with reference to one possible embodiment given as an illustrative and non-limitative example, many changes and variations in the arrangement of components can be carried out by a person skilled in the art according to the above-mentioned description. It is therefore understood that the present invention is meant to comprise all changes and variations in the arrangement of components falling within the protective scope of the following claims.
