Claim 4

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 defining a chamber which is cylindrical, said armature being cylindrical at least in part to slide in said cylindrical chamber, said member being one portion of a valve, said second means being integral with said member and being the remainder of said valve over said one portion thereof, said armature having at least a partially screw-threaded passageway, said passageway extending completely therethrough, said member including a set screw threaded into and rotatably in said passageway, said valve being located on said set screw at one end thereof near one end of said armature, the other end of said set screw having a construction for engagement with a first device to rotate the said set screw, 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 5

The invention as defined in claim 2, wherein the other end of said shaft has a construction to permit engagement therewith by a tool adapted to rotate the same.

Claim 6

A valve assembly comprising: first means defining a chamber; a ferromagnetic armature guided for movement in said chamber; a member in said chamber mounted in 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 in 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 defining a chamber which is cylindrical, said armature being cylindrical at least in part to slide in said cylindrical chamber, said member being one portion of a valve, said second means being integral with said member and being the remainder of said valve over said one portion thereof, said armature having at least a partially screw-threaded passageway, said passageway extending completely therethrough, said member including a set screw threaded into and rotatably in said passageway, said valve being located on said set screw at one end thereof near one end of said armature, the other end of said set screw having a construction for engagement with a first device to rotate the said set screw, said first means including a housing wall having a hole therethrough, and means extending through said hole in engagement with said member, said last named means being movable for adjustment of said member.

Claim 7

A valve assembly comprising: first means defining a chamber; a ferromagnetic armature guided for movement in said chamber; a member in said chamber mounted in 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 in 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 defining a chamber which is cylindrical, said armature being cylindrical at least in part to slide in said cylindrical chamber, said member being one portion of a valve, said second means being integral with said member and being the remainder of said valve over said one portion thereof, said armature having at least a partially screw-threaded passageway, said passageway extending completely therethrough, said member including a set screw threaded into and rotatably in said passageway, said valve being located on said set screw at one end thereof near one end of said armature, the other end of said set screw having a construction for engagement with a first device to rotate the said set screw, said first means including a housing wall having a hole therethrough, and means extending through said hole in engagement with said member, said last named means being movable for adjustment of said member.
