Abstract

Abstract A self-closing, two part fluid-dispensing valve comprising an integral molded generally cup-shaped valve body member providing a valve chamber with an outlet opening. The wall of the valve body member includes a resilient portion which carries a connector means extending into the chamber for supporting a valve member having a valve skirt with surfaces sealingly engaging surfaces on the valve body member. The valve member includes a ported transverse wall which permits fluid communication between the main valve chamber and a valve chamber portion lying between the valve member and the resilient wall portion; the valve skirt being normally biased into closing relationship with respect to the outlet opening and the biasing force of the resilient wall portion being augmented by the fluid pressure head acting upon the internal surface of the resilient wall portion.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 140 words
A fluid-dispensing valve means, comprising: a hollow valve body member having an intEgral body wall providing a valve chamber closed at one end and an opening for entry of fluid therein; said wall being provided with a valve-sealing surface and an outlet opening; said wall including a resilient wall portion having a connector means thereon extending into said chamber, and a valve-sealing member carried by said connector means in spaced relation to said resilient wall portion and defining a valve chamber portion, said valve-sealing member having a skirt having a sealing surface movable into sealing engagement with the sealing surface on said wall for stopping flow of fluid from the valve chamber and chamber portion through the outlet opening; said valve-sealing member having a valve wall carrying said skirt and having ports in said valve wall for fluid communication therethrough.
Claim 2
Dependent Claim 140 words
A fluid-dispensing valve means, comprising: a hollow valve body member having an intEgral body wall providing a valve chamber closed at one end and an opening for entry of fluid therein; said wall being provided with a valve-sealing surface and an outlet opening; said wall including a resilient wall portion having a connector means thereon extending into said chamber, and a valve-sealing member carried by said connector means in spaced relation to said resilient wall portion and defining a valve chamber portion, said valve-sealing member having a skirt having a sealing surface movable into sealing engagement with the sealing surface on said wall for stopping flow of fluid from the valve chamber and chamber portion through the outlet opening; said valve-sealing member having a valve wall carrying said skirt and having ports in said valve wall for fluid communication therethrough.
Claim 3
Dependent Claim 177 words
A fluid-dispensing valve means, comprising: a hollow valve body member having an integral body wall providing a valve chamber closed at one end and an opening for entry of fluid therein; said wall being provided with a valve-sealing surface and an outlet opening; said wall including a resilient wall portion having a connector means thereon extending into said chamber, and a valve-sealing member carried by said connector means in spaced relation to said resilient wall portion and defining a valve chamber portion, said valve-sealing member having a skirt having a sealing surface movable into sealing engagement with the sealing surface on said wall for stopping flow of fluid from the valve chamber and chamber portion through the outlet opening; said valve-sealing member including means providing fluid communication between said valve chamber portion adjacent the resilient wall portion and the remainder of the valve chamber; said means providing fluid communication between said valve chamber portion adjacent to the resilient wall portion and the remainder of the valve chamber comprising a ported transverse wall integral with said valve skirt.
Claim 4
Dependent Claim 177 words
A fluid-dispensing valve means, comprising: a hollow valve body member having an integral body wall providing a valve chamber closed at one end and an opening for entry of fluid therein; said wall being provided with a valve-sealing surface and an outlet opening; said wall including a resilient wall portion having a connector means thereon extending into said chamber, and a valve-sealing member carried by said connector means in spaced relation to said resilient wall portion and defining a valve chamber portion, said valve-sealing member having a skirt having a sealing surface movable into sealing engagement with the sealing surface on said wall for stopping flow of fluid from the valve chamber and chamber portion through the outlet opening; said valve-sealing member including means providing fluid communication between said valve chamber portion adjacent the resilient wall portion and the remainder of the valve chamber; said means providing fluid communication between said valve chamber portion adjacent to the resilient wall portion and the remainder of the valve chamber comprising a ported transverse wall integral with said valve skirt.
