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.
