E' nota la presenza di macchine denominate idropulitrici, che comprendono essenzialmente una pompa che aspira acqua da una linea di adduzione e la manda ad un tubo dotato al= l'estremità di una pistola che viene comandata dall'utente in apertura e chiusura per creare un getto ovvero per fermarlo . The presence of machines known as pressure washers is known, which essentially comprise a pump that sucks water from an adduction line and sends it to a tube equipped at the end of a gun which is controlled by the user in opening and closing to create a jet or to stop it.
Un tipo di pompa comunemente usato nelle idropulitrici come prende un piattello rotante inclinato a contatto col quale vengono mantenuti pistoni dotati di valvole di aspirazione e mandata supportati dal corpo della pompa,! quali in tal modo vengono posti in moto alternativo così da operare sul fluido da pompare che ad essi perviene tramite appositi con= dotti. A type of pump commonly used in pressure washers such as taking an inclined rotating plate in contact with which pistons equipped with suction and delivery valves supported by the pump body are maintained,! which in this way are set in reciprocating motion so as to operate on the fluid to be pumped which reaches them through suitable conduits.
Il corpo delle pompe note comprende,oltre alla porzione di= rettamente connessa al motore contenente gli organi di tras= missione del moto al piattello rotante,due altre porzioni, una delle quali destinata a supportare i pistoni e l'altra destinata a contenere i condotti di aspirazione e mandata del fluido. The body of known pumps comprises, in addition to the portion directly connected to the engine containing the members for transmitting motion to the rotating plate, two other portions, one of which is intended to support the pistons and the other is intended to contain the ducts. suction and delivery of the fluid.
Questo tipo di conformazione si presenta svantaggioso sia perché comporta alti costi di fabbricazione,sia perché il montaggio di tutti gli organi che devono essere assiemati al corpo é complicato e deve avvenire operando su due lati, con conseguente necessità di prevedere tappi o coperchi di chiusura . This type of conformation is disadvantageous both because it involves high manufacturing costs, and because the assembly of all the members that must be assembled to the body is complicated and must take place by operating on two sides, with the consequent need to provide closing caps or lids.
Scopo del presente trovato é quello di realizzare una strut= tura di pompa a piattello rotante che presenti un basso co= sto di fabbricazione e consenta un montaggio rapido ed a» gevole. The object of the present invention is to provide a structure of a rotating plate pump which has a low manufacturing cost and allows quick and easy assembly.
Lo scopo viene raggiunto da una struttura di pompa a piat= tello rotante,secondo il trovato,comprendente un corpo di contenimento e supporto del piattello rotante inclinato connesso ad un alberino di azionamento,e di pistoni con re= lative valvole di aspirazione e mandata mossi dal detto piat= tello operanti sul fluido da pompare convogliato da apposi= ti condotti ricavati nell'ambito del corpo,caratterizzata dal fatto che il detto corpo della pompa comprende due por= zioni amovibilmente connesse:una prima porzione di suppor= to del piattello rotante con relativo alberino di aziona= mento,ed una seconda porzione atta al supporto dei pistoni con le.relative valvole,e comprendente tutti i condotti di convogliamento del fluido trattato. The object is achieved by a rotating plate pump structure, according to the invention, comprising a body for containing and supporting the inclined rotating plate connected to an actuation shaft, and of pistons with relative suction and delivery valves moved. from the said plate operating on the fluid to be pumped conveyed by suitable ducts formed within the body, characterized in that the said pump body comprises two detachably connected portions: a first supporting portion of the rotating plate with relative actuation shaft, and a second portion adapted to support the pistons with the relative valves, and comprising all the conduits for conveying the treated fluid.
Ulteriori caratteristiche e vantaggi risulteranno maggiorniente dalla descrizione di una struttura di pompa illustra» ta a titolo indicativo e non limitativo negli uniti disegni in cui: Further characteristics and advantages will become greater from the description of a pump structure illustrated by way of non-limiting indication in the accompanying drawings in which:
-la figura 1 rappresenta una sezione longitudinale della pompa semplificata mostrando uno solo dei pistoni; figure 1 shows a simplified longitudinal section of the pump showing only one of the pistons;
-la figura 2 rappresenta la sezione col piano II-II di fi= gura 1,in scala leggermente ridotta. - figure 2 represents the section with plane II-II of figure 1, on a slightly reduced scale.
Con riferimento alle suddette figure,sono indicate con 1 e 2 le due porzioni che vengono amovibilmente assiemate a formare il corpo della pomparla porzione 1 é destinata a contenere e supportare l’alberino 3 di azionamento del piat= tello inclinato 4 ed il piattello stesso,mentre la porzione 2 supporta i pistoni come 5 con le relative valvole e com= prende tutti i condotti del fluido. With reference to the aforementioned figures, 1 and 2 indicate the two portions which are removably assembled to form the body of the pump; portion 1 is intended to contain and support the drive shaft 3 of the inclined plate 4 and the plate itself, while the portion 2 supports the pistons as 5 with the relative valves and includes all the fluid ducts.

More precisely, it is noted that said portion 2 comprises an intake duct 6 which feeds two pistons not visible in the figures through the ducts 6a, 6b, and the piston 5 via the duct 6c; obtained in the portion 2 of the body, open towards the attachment section to the portion 1, and the piston 5 is described in detail with all the members connected thereto.
Nella sede 7 é inserita innanzi tutto la boccola 8 che sup= porta le valvole di aspirazione e mandata,e definisce la camera 8a nell'ambito della quale opera il piatone 5· Detta boccola 8 comprende la sede 9 di guida del gambo del= l'otturatore 10 della valvola di aspirazione,che é contenu= to nella porzione di spazio 11 ricavata nell'ambito della boccola in comunicazione tramite la feritoia 12 con la ca= mera 8a,ed é spinto dalla molla 13-contro una superficie di tenuta ricavata nel dischetto 14 che viene associato a scatto alla boccola 8,ed é dotato di foro centrale 14a di comunicazione con il condotto di aspirazione 6c. In the seat 7 is inserted first of all the bushing 8 which supports the suction and delivery valves, and defines the chamber 8a within which the plate 5 operates. obturator 10 of the intake valve, which is contained in the portion of space 11 obtained in the sphere of the bush in communication through the slot 12 with the chamber 8a, and is pushed by the spring 13 against a sealing surface obtained in the disk 14 which is snap-coupled to the bushing 8, and is provided with a central hole 14a for communication with the suction duct 6c.
La boccola 8 comprende anche la luce 15 che mette in comu= nicazione la camera 8a con la porzione di spazio 16 conte= nente l'otturatore 17 della valvola di mandata che é spin= to dalla molla 18 contro una superficie di tenuta ricavata al bordo della luce 15,e presenta il gambo guidato dalla gabbietta 19 associata a scatto alla boccola 8;la porzione di spazio 16 é in comunicazione con il condotto di manda= ta 20. The bush 8 also comprises the port 15 which puts the chamber 8a in communication with the portion of space 16 containing the obturator 17 of the delivery valve which is pushed by the spring 18 against a sealing surface obtained at the edge of the opening 15, and has the stem guided by the cage 19 snap-associated with the bushing 8; the portion of space 16 is in communication with the delivery duct 20.
La guarnizione di tenuta 21 dell'acqua é pure supportata dalla boccola 8. The water seal 21 is also supported by the bushing 8.
Nella sede 7 é poi inserita la boccola 22 che guida e sup= porta il pistone 5 che é mantenuto dall'azione della molla 23 contro la rondella 24 ad esso solidale a contatto con il piattello rotante 4 per essere da questo posto in moto alternativo ;é indicata con 25 la guarnizione di tenuta del= l'olio di lubrificazione,inserita nella boccola 22. The bush 22 is then inserted in the seat 7 which guides and supports the piston 5 which is maintained by the action of the spring 23 against the washer 24 integral with it in contact with the rotating plate 4 to be placed in reciprocating motion from this position; 25 indicates the sealing gasket of the lubricating oil, inserted in the bushing 22.
La porzione 2 del corpo della pompa comprende anche 1 'allo giamento del corpo 26 di una valvola di by-pass,chiuso me= diante il tappo 26a,con otturatore a molla 27 che intercet= ta la luce 28 in comunicazione ,tramite il condotto 20a,con il condotto di mandata 20;nel corpo 26 sono presenti le lu= ci 29 aperte sul condotto di aspirazione 6. The portion 2 of the pump body also comprises the housing of the body 26 of a by-pass valve, closed by means of the plug 26a, with a spring obturator 27 which intercepts the communicating port 28, through the duct. 20a, with the delivery duct 20; in the body 26 there are the ports 29 open on the suction duct 6.
Quando la pistola posta al termine del tubo collegato con il condotto di mandata 20 é chiusa,1'acqua nella luce 28 preme sull'otturatore 27 e ne determina l'apertura con con= seguente ricircolo dell'acqua all'aspirazione tramite le luci 29;quando la pistola viene aperta la molla riporta l'otturatore in posizione di chiusura,ed il ricircolo cessa. Da quanto descritto risulta evidente innanzi tutto la gran= de semplicità del trovato nel quale le due porzioni del core po potranno essere realizzate per fusione con successive lavorazioni di finitura ottenute con un'unica presa su mac= china utensile; la porzione 2 si presta anche ad essere van= taggiosamente. realizzata in materia plastica senza lavorai zione alcuna. When the gun placed at the end of the tube connected to the delivery duct 20 is closed, the water in the port 28 presses on the shutter 27 and opens it with the consequent recirculation of the water upon suction through the ports 29 ; when the gun is opened, the spring returns the shutter to the closed position, and recirculation stops. From what has been described it is evident first of all the great simplicity of the invention in which the two portions of the core can be made by fusion with subsequent finishing operations obtained with a single grip on a machine tool; portion 2 also lends itself to being advantageously. made of plastic without any machining.
Il montaggio di tutti gli organi compresi nella porzione 2 si presenta poi semplicissimo perché ,operando da una so= la parte,si inizierà ad inserire nelle sedi come 7 le boc= cole come 8 con le valvole premontate, per completare poi il montaggio con le boccole come 22 con i relativi pistoni come 5;il tutto,come detto,operando da una sola parte ed in una sola direzione. The assembly of all the parts included in the portion 2 is then very simple because, by operating from one part, you will begin to insert the ports in the seats as 7 as 8 with the pre-assembled valves, to then complete the assembly with the bushings such as 22 with the relative pistons such as 5; the whole, as mentioned, operating from one side only and in one direction only.
Rapidissimo é anche il montaggio del corpo 26 della valvo= la di by-pass. The assembly of the body 26 of the by-pass valve is also very rapid.
Nella pratica realizzazione del trovato tutti i particola= ri potranno essere sostituiti con altri elementi tecnica= mente equivalenti;inoltre i materiali impiegati,nonché le forme e le dimensioni,potranno essere qualsiasi a secon= da delle esigenze. In the practical embodiment of the invention, all the details may be replaced with other technically equivalent elements; furthermore, the materials used, as well as the shapes and dimensions, may be any according to requirements.
