Abstract
An over-molded fluid control value for use in fluid delivery systems. An embodiment of the fluid control valve includes a rigid substrate having a opening defined therein, and a valve structure fabricated of an elastomeric material. The valve structure is over-molded over at least a portion of the rigid substrate and including a valve portion extending over the opening, the valve portion movable in response to a differential fluid pressure to allow fluid flow.
Claims25
An over-molded fluid control valve, comprising:
- a rigid substrate having a opening defined therein;
- a valve structure fabricated of an elastomeric material, said valve structure over-molded over at least a portion of the rigid substrate and including at least one valve portion extending over said opening, the valve portion normally closed to prevent fluid flow, the valve portion movable in response to a differential fluid pressure to allow fluid flow.
The valve of claim 8, wherein said membrane portion includes a disk portion of increased thickness.
A fluid control assembly, comprising:
- a host part having a fluid port and a circumferential boss;
- an over-molded fluid control valve disposed in said circumferential boss to control fluid flow through said fluid port, the valve comprising:
- a rigid substrate having a opening defined therein;
- a valve structure fabricated of an elastomeric material, said valve structure over-molded over at least a portion of the rigid substrate and including at least one valve portion extending over said opening and normally preventing fluid flow, the valve portion movable in response to a differential fluid pressure to allow fluid flow.
An over-molded disk valve for fluid flow control, comprising:
- a rigid substrate having a opening defined therein;
- a valve seat structure defining a valve seal, the valve seat structure disposed in or adjacent the opening;
- a valve structure fabricated of an elastomeric material, said valve structure over-molded over at least a portion of the rigid substrate and including a membrane portion extending over said opening, the membrane portion normally in sealing contact against said valve seal, the membrane portion movable in response to a differential fluid pressure to allow fluid flow.
A ganged set of fluid control valves, comprising:
- a rigid substrate having a plurality of openings defined therein;
- a valve structure fabricated of an elastomeric material, said valve structure over-molded over at least a portion of the rigid substrate and including at least one valve portion extending over each of said plurality of openings, each valve portion normally closed to prevent fluid flow, the valve portion movable in response to a differential fluid pressure to allow fluid flow.
