PNEUMATISCHES VENTIL ZUR STEUERUNG VON DRUCKLUFTSTROEMEN

摘要

The invention relates to a pneumatic valve for the regulation of pneumatic flows, using contact-free control, the object being to provide such a valve which is controlled in a contact-free manner and can switch high operating pressures without intermediate amplifiers. For this purpose, the pneumatic valve is characterised in that a pivotably supported single or double lever (3) is fitted on one or both sides of the pivoting axis (13) with a permanent magnet (14, 15) and a control nozzle (2) is closed and opened via a plunger (7) by means of a ferromagnetic or magnetic switching part (17), which can be moved into position, the air flow of which control nozzle (2) is used for closing and opening an operating piston (5). ……
