  • the needle (2A) is moved for cleaning relative to the immovable cleaning body (3), while according to the embodiments shown in FIGS. 3 to 7, the cleaning body (3) is moved relative to the fixed needle
  • an actuating means (4) is preferably selected which effects the relative movement between the cleaning body by means of the engine's own energies such as temperature or pressure drops or vibrations.
  • an expansion element (4) is preferably used, which expands when the engine is running via the supply of heat from the hot crankcase gases and thus acts forcefully on one
  • Plunger (4A) acts, which is then extended against the action of a spring (5).
  • the spring (5) is also housed in the hollow inner electrode (2) and can be referred to as a resetting actuating element.
  • the needle (2A) is arranged in a sleeve (4B) arranged on the inflow side and connected to the expansion element (4). It can be pressed into it, for example.
  • the sleeve (4B) can be connected in one piece to the expansion element (4) or can also be arranged as a separate component thereon.
  • the plunger (4A) Arranged on the side of the expansion element (4) opposite the needle (2A) is the plunger (4A), which is supported as an abutment inside the hollow inner electrode (2) on a pin (6) fixed there.

  • the inner electrode (2) has a small opening in which the cleaning body (3) is pressed or clipped.
  • the cleaning body (3) itself is preferably formed from an elastomer plate which is pierced by the needle (2A) for cleaning. However, it is e.g. also provided to form the cleaning body as a cleaning brush with radially inwardly projecting micro bristles.
  • the operation of the needle cleaning according to the embodiment of FIGS. 1 and 2 is as follows: After the engine is switched on, the crankcase gases that are hot while the engine is running and the hot engine compartment as a whole heat the expansion element (4).
  • the needle (2A) pierces the cleaning body (3).
  • the needle (2A) protrudes from the second section (2B) of the inner electrode (2) as the section of the inner electrode (2) forming the corona.

  • the pin (6) serving as a counterbearing for the plunger (4A) is advantageously introduced into the hollow inner electrode (2) and held there.

Abstract

L'invention concerne un séparateur électrostatique conçu pour la séparation de particules fluides ou solides contenues dans un flux gazeux. Ce séparateur électrostatique comprend un tube (1), traversé en sens longitudinal par le gaz à purifier et dont la paroi intérieure (1A) forme une électrode de précipitation pour les particules à séparer. Une électrode interne (2) est agencée, de manière décalée dans le sens longitudinal, au centre de l'intérieur du tube (1) et un champ électrique haute tension est formé dans l'espace situé entre cette électrode interne et l'électrode de précipitation. L'électrode interne (2) présente, côté entrée, une première partie (2A) de faible surface de section et, côté sortie, une seconde partie (2B) de surface de section supérieure à celle de la première partie. Cette première partie sert essentiellement à la formation d'une décharge en couronne et la seconde partie à la formation d'un champ de séparation électrostatique. Un organe de purification (3), qui sert à la purification de la partie formant la décharge en couronne, est déplacé par rapport à ladite électrode interne et mis en contact avec cette dernière. L'élément d'actionnement (4) est agencé pour entraîner un mouvement relatif à faible encombrement au sein de l'électrode interne creuse (2).
