Miniature electrically operated solenoid valve

摘要

A miniature solenoid valve including a housing defining an axial passage with a valve seat formed integral with the housing and including a minute flow orifice in fluidic communication with the axial passage. A magnetic actuator is positioned within the axial passage and is adapted for reciprocating movement along an actuation axis. A valve element is engagable with the integrally formed valve seat to substantially prevent flow through the minute flow orifice in response to displacement of the magnetic actuator along the actuation axis. In another embodiment, a connection element is formed integral with the housing and is configured for sealing engagement with a pressurized flow source to supply flow to the flow orifice. In a further embodiment, the housing defines a closed end and an open end, with a pole piece engaged with the valve housing and including a transverse portion covering the open end of the valve housing.
