Elektromagnetisches Hochgeschwindigkeitsventil für Fluidum unter Druck, zum Beispiel für pneumatische Kreisläufe.

摘要

The solenoid valve comprises an electromagnet (117) arranged in a chamber (12) into which an inlet duct (9) and an outlet duct (111) of the solenoid valve open, whereby the coil (22) is constantly ventilated by the compressed air itself. The armature of the electromagnetic has a disc (42) for shutting off the outlet duct (111) and is formed by a plate (34) which is urged into the closed position of the solenoid valve by the compressed air. The plate (34) rotates about a beading (145) of elastomeric material and exhibits extremely low inertia, whereby the solenoid valve can be operated at high frequency. The chamber (12) can house a plurality of electromagnets (117) each of which controls a shut-off member for a corresponding outlet duct (111). The body (5) also comprises an interchangeable shell which has funnel-shaped chambers for directing the air of at least one set of ducts to a common outlet aperture.
