Elektromagnetisches Druckregelventil

摘要

A solenoid operated pressure control valve (10) of the type using a spool valve member (24) for controlling flow from a source inlet (60) to a control outlet port (64) and to an exhaust port (68). The solenoid has a reduced area portion (20) of the flux collector (14) in magnetic loop forming an annular air gap remote from the working air gap. The reduced flux across the annular air gap compensates for the rapid flux increase as the working air gap closes.
