Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
209 words
A vibration resistance valve apparatus comprising: a stem structure which is axially displaceable between an open and a closed position, said stem structure including an elongated stem and a support body attached to one end of said stem, said support body having a bearing surface and a guide surface; a valve seat structure having a spherical seat surface; a valve body having a spherical surface portion which is engageable with said seat surface for preventing fluid flow therebetween, said valve body having an opening therein for housing said support body, said valve body having a bearing surface and a guide surface which bound said opening, said valve body's bearing surface being rotatably supportable by said support body and said valve body's guide surface being separated from said support body; and a stabilizing ring being attached to one of said bodies and being unattached to the other body, said stabilizing ring extending into said separation between said guide surfaces of said valve body and said support body, said stabilizing ring being axially narrow compared to said guide surfaces' length, said stabilizing ring lying in a plane, wherein said plane is defined by the contact line between the spherical valve body and seat when said valve is engaged with said seat.
Claim 2
Dependent Claim
209 words
A vibration resistance valve apparatus comprising: a stem structure which is axially displaceable between an open and a closed position, said stem structure including an elongated stem and a support body attached to one end of said stem, said support body having a bearing surface and a guide surface; a valve seat structure having a spherical seat surface; a valve body having a spherical surface portion which is engageable with said seat surface for preventing fluid flow therebetween, said valve body having an opening therein for housing said support body, said valve body having a bearing surface and a guide surface which bound said opening, said valve body's bearing surface being rotatably supportable by said support body and said valve body's guide surface being separated from said support body; and a stabilizing ring being attached to one of said bodies and being unattached to the other body, said stabilizing ring extending into said separation between said guide surfaces of said valve body and said support body, said stabilizing ring being axially narrow compared to said guide surfaces' length, said stabilizing ring lying in a plane, wherein said plane is defined by the contact line between the spherical valve body and seat when said valve is engaged with said seat.
Claim 3
Dependent Claim
26 words
The vibration resistant valve apparatus of claim 1, wherein said engageable bearing surfaces have spherical shapes which permit relatively free movement and ensure surface contact therebetween.
Claim 4
Dependent Claim
43 words
The vibration resistant valve apparatus of claim 1, wherein said support body's engageable bearing surface is disposed on one axial end region of said support body and said stabilizing ring is axially separated therefrom toward the opposite axial end of said support body.
Claim 5
Dependent Claim
42 words
The vibration resistant valve apparatus of claim 1, wherein said stabilizing ring and unattached body are separated during non-engagement of the valve by a distance greater than or equal to the bodies' displacement toward each other during valve engagement with the seat.
Claim 6
Dependent Claim
37 words
The vibration resistant valve apparatus of claim 1, wherein said stabilizing ring substantially lies in the plane defined by the contact line between the spherical valve body and seat when said valve is engaged with said seat.
Claim 7
Dependent Claim
33 words
The vibration resistant valve apparatus of claim 1, said support body further comprising: a spherical surface for mateably abutting said valve body to limit the stem structure's axial displacement in the closing direction.
Claim 8
Dependent Claim
62 words
The vibration resistant valve apparatus of claim 1, said valve body comprising a valve plug and a valve nut in threaded engagement therewith to permit axial adjustment of the valve body's extreme open and closed positions and to permit assembly and adjustment of the valve support body with said valve body, said valve nut having said valve body's bearing and guide surfaces.
