Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
197 words
A valve assembly comprising: first means defining a chamber; a ferromagnetic armature guided for movement in said chamber; a member in said chamber mounted on said armature, said member being adjustable in first and second directions to move said member in third and fourth directions, respectively, relative to said armature; a body mounted on said first means providing a valve seat having an inlet opening therethrough; a solenoid-like winding fixed relative to and around said first means in a position to cause, when energized, movement of said armature from a first position thereof to a second position thereof; and second means movable with said member to abut said valve seat and to close said inlet opening, abutment of said second means with said valve seat taking place when said member is in a predetermined position, the position of said armature relative to said valve seat when said abutment takes place being changeable by adjustment of said member, said first means including a plate having a hole extending completely therethrough, a shaft rotatable in said plate hole having one end in engagement with said member to rotate the same therewith and to adjust the same by said rotation.
Claim 2
Dependent Claim
197 words
A valve assembly comprising: first means defining a chamber; a ferromagnetic armature guided for movement in said chamber; a member in said chamber mounted on said armature, said member being adjustable in first and second directions to move said member in third and fourth directions, respectively, relative to said armature; a body mounted on said first means providing a valve seat having an inlet opening therethrough; a solenoid-like winding fixed relative to and around said first means in a position to cause, when energized, movement of said armature from a first position thereof to a second position thereof; and second means movable with said member to abut said valve seat and to close said inlet opening, abutment of said second means with said valve seat taking place when said member is in a predetermined position, the position of said armature relative to said valve seat when said abutment takes place being changeable by adjustment of said member, said first means including a plate having a hole extending completely therethrough, a shaft rotatable in said plate hole having one end in engagement with said member to rotate the same therewith and to adjust the same by said rotation.
Claim 3
