Abstract
A valve having a mechanism for stabilizing the flow of fluid, such as in response to a nonlinear force, is disclosed herein. According to an embodiment of the valve, a tube is anchored within a retainer, and a solenoid mounted on the tube. A pole piece is fixed within the tube, and an armature is slidably disposed within the tube adjacent to the pole piece. A generally frustoconical gap is defined between the pole piece and the armature. A flexible, non-magnetic washer is disposed within the conical gap. The flexible washer counteracts the effect of a non-linear magnetic force by providing a non-linear force in opposition. The result is that the flow of fluid though the valve as well as the valve pressure is stabilized, in contrast with the prior art.
Claims38
A valve comprising:
- a generally tubular housing;
- a movable piece having a first end surface, the movable piece being disposed within the tubular housing and movable along an axis of the tubular housing to increase or decrease the flow of fluid through the valve;
- a fixed piece having a second end surface, the fixed piece being disposed within the tubular housing adjacent to the movable piece so that the first and second surfaces face one another;
- and
- a dampener disposed between the first and second surfaces for dampening the movement of the movable piece relative to the fixed piece to stabilize a flow of fluid through the valve.
A valve comprising:
- a generally tubular housing;
- a movable piece disposed within the tubular housing and movable along an axis of the tubular housing to increase or decrease the flow of fluid through the valve, the movable piece having an axial bore extending at least partially therethrough, the movable piece having a first end surface concentric around an opening to the axial bore;
- a fixed piece disposed within the tubular housing, the fixed piece having an axial bore extending at least partially therethrough, the fixed piece having a second end surface concentric around an opening to the axial bore, the fixed piece being adjacent to the movable piece so that the first and second end surfaces face one another;
- a resilient member disposed within the axial bores for biasing the movable and the fixed piece away from each other;
- and
- a dampener positioned between the end surfaces to dampen the movement of the movable piece relative to the fixed piece, thereby stabilizing a flow of fluid through the valve.
A valve comprising:
- a generally tubular housing;
- a movable piece disposed within the tubular housing and movable along an axis of the tubular housing to increase or decrease the flow of fluid through the valve, the movable piece having an axial bore extending at least partially therethrough, the movable piece having a first end surface concentric around the axial bore;
- a rigid member fixed within the axial bore of the movable piece;
- a fixed piece disposed within the tubular housing, the fixed piece having an axial bore extending at least partially therethrough, the fixed piece having a second end surface concentric around the axial bore, the fixed piece being adjacent to the movable piece so that the first and second end surfaces faced one another;
- a sliding member slidably disposed within the axial bore of the fixed piece and adjacent to the rigid member;
- and
- a dampener positioned concentrically around the axial bores between the end surfaces to dampen the movement of the movable piece relative to the fixed piece, thereby stabilizing a flow of fluid through the valve.
A valve comprising:
- a generally tubular housing;
- an movable piece disposed within the tubular housing and movable along an axis of the tubular housing to vary a flow of fluid through the valve, the movable piece having an annular, non-planar end surface;
- a fixed piece having an annular, non-planar end surface and disposed within the tubular housing adjacent to the movable piece so that the end surfaces face each other and are spaced from each other to define a gap therebetween;
- and
- a dampener disposed within the gap against the end surfaces for dampening the movement of the movable piece relative to the fixed piece to stabilize a flow of fluid through the valve.
