Este cunoscută pompa electrostatică cu membrană, care include un canal închis cu părţi laterale de intrare şi de ieşire, dotate cu supape de branşare, un electrod imobil şi unul mobil în formă de membrană, conectaţi la o sursă de curent [1]. The electrostatic membrane pump is known, which includes a closed channel with inlet and outlet sides, equipped with branch valves, a fixed electrode and a movable one in the form of a membrane, connected to a current source [1].

Dezavantajul acestei pompe constă în forţa mică de interacţiune dintre electrodul mobil şi cel imobil, fapt care nu permite crearea unei pompe de o înaltă eficienţă. The disadvantage of this pump lies in the low interaction force between the mobile and stationary electrodes, which does not allow the creation of a highly efficient pump.

Invenţia se explică prin desenele din fig. 1-2, care reprezintă: The invention is explained by the drawings in Fig. 1-2, which represent:

- fig. 2, schema pompei electrostatice cu piston conform celei de-a doua variante. - Fig. 2, diagram of the electrostatic piston pump according to the second variant.

Pompa electrostatică cu piston, conform primei variante, include o cameră cilindrică din material dielectric 1, părţile laterale de intrare şi de ieşire ale căreia sunt dotate cu supape de branşare, totodată în interiorul camerei 1 este amplasat un piston cav 4 în formă de bilă din material conductor, electrozi în formă de plasă 2, amplasaţi convex în direcţia pistonului 4, fixaţi de părţile laterale ale camerei 1 prin intermediul unor arcuri 5, şi conectaţi la o sursă de curent 3, iar pe pereţii camerei 1 sunt amplasaţi consecutiv electrozi inelari de accelerare 6, conectaţi peste unul la polii de aceeaşi polaritate ai sursei 3. Pompa de asemenea include o conductă 7 cu o supapă, fixată de partea exterioară a camerei 1, şi care uneşte spaţiile, formate de părţile laterale ale camerei 1 şi electrozii 2. The electrostatic piston pump, according to the first variant, includes a cylindrical chamber made of dielectric material 1, the inlet and outlet sides of which are equipped with branch valves, at the same time inside the chamber 1 there is placed a hollow piston 4 in the shape of a ball made of conductive material, mesh-shaped electrodes 2, placed convexly in the direction of the piston 4, fixed to the side parts of the chamber 1 by means of springs 5, and connected to a current source 3, and on the walls of the chamber 1 there are consecutively placed annular acceleration electrodes 6, connected one above the other to the poles of the same polarity of the source 3. The pump also includes a pipe 7 with a valve, fixed to the outer side of the chamber 1, and which unites the spaces formed by the side parts of the chamber 1 and the electrodes 2.

Pompa, conform variantei a doua, include o conductă din material dielectric 7 cu o supapă, fixată rigid de părţile laterale ale camerei 1, coaxial ei, şi care trece printr-o gaură străpunsă executată în piston 4, cu posibilitatea mişcării libere a pistonului 4 de-a lungul conductei 7, totodată pe capetele conductei 7 sunt executate găuri străpunse. Conducta 7 este executată din fluoroplast. The pump, according to the second variant, includes a pipe made of dielectric material 7 with a valve, rigidly fixed to the sides of the chamber 1, coaxially with it, and passing through a through hole made in the piston 4, with the possibility of free movement of the piston 4 along the pipe 7, at the same time through holes are made on the ends of the pipe 7. The pipe 7 is made of fluoroplastic.

Pompa electrostatică cu piston, conform primei variante, funcţionează în felul următor. The electrostatic piston pump, according to the first variant, operates as follows.

La aplicarea tensiunii cu polaritate diferită la electrozii 2 şi la electrozii inelari de accelerare 6, conectaţi peste unul la polii de aceeaşi polaritate ai sursei 3, pistonul 4 se deplasează de la un electrod 2 spre celălalt. O deplasare mai intensivă a pistonului 4 se explică prin reîncărcarea pistonului 4 de către electrozii inelari 6. Obţinând o sarcina pozitivă la electrodul 6, pistonul 4 este atras la celălalt electrod 6, care are sarcină negativă. Descărcându-se la cel cu sarcină negativă şi primind sarcină negativă, pistonul 4 este atras de electrodul pozitiv. Ajungând la unul din electrozii 2, pistonul 4 se întoarce în partea opusă şi din nou sub acţiunea electrozilor inelari 6 se îndreaptă spre celălalt electrod 2. Totodată gazele sau lichidele dielectrice trec liber prin părţile laterale de intrare şi de ieşire cu supape de branşare şi prin conducta 7. When applying voltage of different polarity to electrodes 2 and to the accelerating ring electrodes 6, connected across each other to the poles of the same polarity of the source 3, the piston 4 moves from one electrode 2 to the other. A more intensive movement of the piston 4 is explained by the recharge of the piston 4 by the ring electrodes 6. Obtaining a positive charge at the electrode 6, the piston 4 is attracted to the other electrode 6, which has a negative charge. Discharged to the one with a negative charge and receiving a negative charge, the piston 4 is attracted to the positive electrode. Reaching one of the electrodes 2, the piston 4 turns to the opposite side and again under the action of the ring electrodes 6 it moves towards the other electrode 2. At the same time, dielectric gases or liquids freely pass through the inlet and outlet side parts with branch valves and through the pipe 7.

Pompa electrostatică cu piston, conform variantei a doua, funcţionează în felul următor. The electrostatic piston pump, according to the second variant, operates as follows.

În acest caz pistonul 4 se mişcă liber, prin intermediul găurii străpunse executate în el, de-a lungul conductei 7, care este fixată rigid de părţile laterale ale camerei 1, coaxial ei. Totodată gazele sau lichidele dielectrice trec liber prin părţile laterale de intrare şi de ieşire cu supape de branşare şi prin conducta 7, prin intermediul găurilor străpunse executate pe capetele ei. Conducta 7 este executată din fluoroplast. Pe lângă faptul că acest material este un dielectric bun, executarea conductei 7 din fluoroplast asigură şi o lunecare mai eficientă a pistonului 4 pe ea. In this case, the piston 4 moves freely, through the through hole made in it, along the pipe 7, which is rigidly fixed to the sides of the chamber 1, coaxially with it. At the same time, dielectric gases or liquids pass freely through the inlet and outlet sides with branch valves and through the pipe 7, through the through holes made on its ends. The pipe 7 is made of fluoroplastic. In addition to the fact that this material is a good dielectric, the execution of the pipe 7 from fluoroplastic also ensures a more efficient sliding of the piston 4 on it.

În lipsa conductei 7 atât în prima, cât şi în a doua variantă, pompa poate face doar o jumătate de ciclu, eliminând dintr-o singură dată lichidul prin partea laterală cu supapă de ieşire. Prezenţa conductei 7 în ambele variante permite de a efectua orice număr de cicluri fără limită. In the absence of pipe 7 in both the first and second variants, the pump can only perform half a cycle, eliminating the liquid at once through the side with the outlet valve. The presence of pipe 7 in both variants allows for any number of cycles without limit.

Mişcarea cu alternare a pistonului 4 de la un electrod 2 spre celălalt şi prezenţa părţilor laterale cu supape de branşare asigură o mişcare direcţionată a gazelor şi lichidelor dielectrice. The alternating movement of the piston 4 from one electrode 2 to the other and the presence of the side parts with branch valves ensure a directed movement of the dielectric gases and liquids.
