Solenoid valve

摘要

A solenoid valve includes a housing defining an interior cavity and at least a first and second port coupled to the housing and having associated passages configured to be in fluid communication with the interior cavity. The solenoid valve further includes a valve seat disposed about an opening between the first and second ports and interior cavity. The valve seat is integrally formed with the housing, such that the housing and valve seat are a single unitary structure. The solenoid valve further includes a bobbin supporting a coil and an armature and seal movably disposed within the bobbin and relative to the coil. The armature and seal are moveable between an open position and a closed position relative to the valve seat, wherein, in the closed position, the seal sealingly engages with the valve seat.

1. A solenoid valve comprising:
a housing defining an interior cavity and at least one valve seat; a first valve body configured to be secured to said housing, said first valve body comprising a first port; a second valve body configured to be secured to said housing, said second valve body comprising at least a second port, wherein said first and said second port each include an associated passage configured to be in fluid communication with said interior cavity of said housing through said at least one valve seat; a bobbin disposed within said interior cavity of said housing, said bobbin supporting a coil; an armature having a seal coupled to a portion thereof and disposed within said bobbin and relative to said coil, said armature and seal configured to move from a first position, unsealed with an opening of said valve seat, to a second position sealingly engaged with said opening of said valve seat when said coil is energized; and a bracket configured to retain said bobbin, said coil, said armature, and said armature seal within said internal cavity of said housing, wherein said bracket is further configured to complete a magnetic circuit and contact said armature only when said solenoid valve is energized.
