Abstract
An assembly comprises a manifold and a valve. The manifold has a portion defining a bore having a first end and a second end. The valve is at least partially disposed within the manifold and includes a coil configured to generate a magnetic field; a bobbin configured to house the coil; a pole piece located near the bobbin; and a housing. The pole piece includes a first end configured for insertion into the bore of the manifold; a circumferentially extending groove located near the first end of the pole piece; an o-ring disposed in the circumferentially extending groove; and a radially outwardly extending flange located near the circumferentially extending groove that is configured to engage both the portion of the manifold defining the first end of the bore and the bobbin. The housing includes a tab configured to fasten the valve to the manifold.
