Abstract:
A modified vacuum actuated valve assembly and sealing mechanism is provided for improved sub-atmospheric flow stability characterized by the absence of delivery pressure spikes and flow excursions. The valve assembly includes a non-stationary thermoplastic seat and a stabber. The stabber is characterized by a top portion having a circular periphery designed to mechanically engage and disengage with an inner sealing surface of the thermoplastic seat. The sealing surface is coined to eliminate surface irregularities contained therein, thereby producing a relatively smooth coined mating inner sealing surface for the circular top portion of the stabber. The valve assembly also includes a modified bellows capable of fine tuning the delivery pressure of the valve assembly.

Claim (Index 15):
A sealing structure and mechanism for a valve assembly ( 10 ), comprising:\n a stationary seat ( 11 ) consisting essentially of a thermoplastic material and characterized by the absence of elastomeric material; the stationary seat ( 11 ) comprising an opening ( 28 ) extending from an outer surface ( 27 ) of the stationary seat ( 11 ) to an inner sealing surface ( 26 ) of the stationary seat ( 11 ), said seat ( 11 ) further comprising a grooved region ( 15 ) extending along said inner sealing surface ( 26 ) of said stationary seat ( 11 ); said grooved region ( 15 ) of the seat ( 11 ) comprising a surface configured to compress within a predetermined zone upon engagement with the top portion ( 29 ) of the stabber ( 12 ); the stabber ( 12 ) comprising a body portion ( 30 ) and the top portion ( 16 ) each of which is situated within the interior of the stationary seat ( 11 ); the interior of the stationary seat ( 11 ) defined, at least in part, by an inner diameter greater than an outer diameter of the top portion ( 16 ) and an outer diameter of the body portion ( 30 ) thereby creating a passageway ( 20 ) between the stabber ( 12 ) and the seat ( 11 ); wherein said top portion ( 16 ) of the stabber ( 12 ) is adapted to move between a closed configuration and an open configuration, said closed configuration defined by said top portion ( 16 ) of the stabber ( 12 ) abutted against said grooved region ( 15 ) of the stationary seat ( 11 ) so as to be maintained in mechanical engagement therealong, said engagement creating a seal that blocks the passageway ( 20 ), thereby creating a closed configuration of the valve assembly ( 10 ); the open configuration defined by the top portion ( 16 ) of the stabber ( 12 ) spaced away from the grooved region ( 15 ) along the inner sealing surface ( 26 ) of the stationary seat ( 11 ) so as to mechanically disengage the seal to unblock the passageway ( 20 ) and create a gap between the top portion ( 16 ) of the stabber ( 12 ) and the inner sealing surface ( 26 ) of the stationary seat ( 11 ) to create an open configuration of the valve assembly ( 10 ).
