Abstract

Oscillating piston compressor which has an electro-magnetic coil arrangement and an armature connected to the piston which oscillates longitudinally. The unit has two compressors (24-27) with an intermediary electrical drive (20, 22; 21, 23). These compressors comprise two piston units which are arranged one behind the other in such a manner that in the middle of the cylinder (19) a work chamber for two compressor pistons (25, 26) is available. The electrical drive can be of the alternating current type so that a changeover switch in the current circuit is not necessary. Also, the compressors can be used to produce electrical energy, and be activated by pressure gas.

Die beiden Schwingorgane sind hintereinander angeordnet und führen Gegentaktschwingungen aus. An den aussen gelegenen Enden der beiden Schwingorgane ist je ein Hohlraum für Expansionen und Kompressionen angeordnet und zweckmässigerweise befindet sich ein dritter, von beiden Schwingorganen gemeinsam beeinflusster hohlraum zwischen den innen gelegenen und einander zugekehrten Enden der beiden Schwingorgane. Jedem Schwingorgan ist ein eigener elektromagnetisch arbeitender Antrieb zur Einleitung und Aufrechterhaltung der Schwingbewegung zugeordnet, sowie gegebenenfalls eine geeignete Umschalteinrichtung in den Stromversorgungsleitungen des Antriebs. Die Hohlräume arbeiten mit Ventilanordnungen zusammen, die durch den Druck in den Hohlräumen oder auch mechanisch oder elektrisch gesteuert werden. Die Schwingorgane selbst stehen mit Membranen oder Schwingkolben in Verbindung, die den Abschluss der jeweiligen Hohlräume bilden.These show: FIG. 1 the longitudinal section through a compressor with membranes as oscillating members Fig. 2 shows the longitudinal section through a compressor with piston as Oscillating organs The present oscillating piston compressor is preferably used for Cegentaktbetrieb designed with two oscillating organs so that the forces of the oscillating Masses are compensated. The two oscillating organs are arranged one behind the other and carry out push-pull oscillations. At the outer ends of the two oscillating organs a cavity for expansions and compressions is arranged and expediently there is a third cavity that is influenced by both oscillating organs between the inner and facing ends of the two oscillating organs. Each oscillating organ has its own electromagnetically operating drive for initiation and maintaining the oscillating movement, and possibly a Suitable switching device in the power supply lines of the drive. the Cavities work together with valve assemblies caused by the pressure in the cavities or also be controlled mechanically or electrically. The vibrating organs themselves are connected to diaphragms or oscillating pistons, which complete the respective Form cavities.

Nachstehend ist als Ausführungsbeispiel ein nach dem oben angegebenen Prinzip arbeitender Membrankompressor mit zwei Gegentakt-Schwingorganen und je einem elektromagnetischen Antrieb hierfür anhand von Fig. 1 beschrieben.

Das untcre Schwingorgan umfasst einen entsprechenden Anker 6 und die beiden Membranen 7 und 8, und arbeitet mit dem stationären Spulenpaar 5 zusammen. Die jeweils innen gelegenen Spulen der Spulenpaare 1 und 5 werden über die Leitung 11, die beiden aussengelegenen Spulen über die Leitung 12 seitens der Stromquelle 10 mit Strom versorgt, wobei der Umschalter 9 nur jeweils die eine oder die andere Spulengruppe einschaltet. Diescr Umschalter 9 wird, wie schematisch angedeutet, vom oberen Schwingorgan über eine Nockenscheibe oder auf andere geeignete Weise so gesteuert, dass er beim Erreichen der inneren Endlage beider Schwingorgane die hierbei wirksame innere Spulengruppe ausschaltet und die äussere Spulengruppe einschaltet, wie in Fig. 1 angedeutet, so dass die Schwingbewegung aufrecht erhalten wird.The following is an exemplary embodiment according to the above Principle working diaphragm compressor with two push-pull oscillating elements and one each electromagnetic drive for this purpose described with reference to FIG. The upper vibrating organ is from the stationary coil pair 1 via the preferably designed as a permanent magnet Armature 2 driven, which pierces with the two membranes 3 and 4 in connection.
