초록 ▼

Positioned within the inlet end internal cavity is a resilient valve member normally biased to a sealed closed position. The valve member includes a generally cylindrical wall with a diaphragm with a pre-slit partitioned across the wall. The cylindrical wall dimensioned to be slightly larger in diameter than the inlet end cavity of the housing except for a recessed area where the diaphragm is positioned. The cylindrical wall providing inward compressive force except in the recess area permitting the diaphragm to remain in a steady state normally closed position without excessive inwardly compressive force.

대표청구항 ▼

[ I claim:] [1.] A valve assembly comprising a housing having an inlet end, an outlet end and a connecting passageway therebetween, said inlet end including a cavity in turn having inner rigid side walls in contacting receipt of a resilient valve member, said valve member including a diaphragm portion with a slit therethrough and outer walls, a diaphragm wall laterally disposed between said valve outer walls and across said connecting passageway, said diaphragm wall including a slit, said slit defining opposed slit leaves each having a centrally disposed edge, said leaf edges in turn in normal sealing contact with each other so as to normally close said connecting passageway, said valve member outer walls generally conforming in shape to that of said inlet end cavity and dimensioned so as to have at least one portion thereof disposed distally from said diaphragm wall of an oversized greater dimension than said inlet end cavity whereby said valve member is compressed by said cavity inner side walls at said oversized portion but not compressed at valve member areas proximal said diaphragm wall so that such compression does not materially alter the normal sealing contact between said diaphragm leaves.
