1. A valve assembly comprising:
- a plug having a valve seat at a distal portion of the plug, said plug having an outer perimeter defining a first cross sectional area;
a holder cantileveredly connected to the plug;
an actuator operably connected to the holder;
a poppet connected to the actuator, said poppet driven by the actuator intermediate an open configuration wherein a fluid passes intermediate the valve seat and the poppet and a closed configuration wherein the poppet forms a seal relative to the valve seat;
wherein the holder, actuator and poppet are positioned within a second cross sectional area parallel to the first cross sectional area when in at least one of the open and closed configurations, said second cross sectional area bounded by a parallel cross section of the first cross sectional area; and
a connector connecting the actuator to the poppet, said connector having a hook with opposing barbs, and said poppet having a cavity with opposing slots in a resilient sleeve, said barbs retained in the slots.

Abstract
A valve assembly provides a holder cantileveredly attached to a boss on an end cap to axially dispose an actuator and a poppet on an axis with a valve seat formed in the end cap. The actuator is preferably a shape memory alloy actuator. The end cap may be placed in line with a fluid system such as in a gas oven so that an electrical communication with an igniter is provided.

4. A valve assembly comprising:
-
a plug having a valve seat at a distal portion of the plug, said plug having an outer perimeter defining a first cross sectional area; a holder cantileveredly connected to the plug; an actuator operably connected to the holder; a poppet connected to the actuator, said poppet driven by the actuator intermediate an open configuration wherein a fluid passes intermediate the valve seat and the poppet and a closed configuration wherein the poppet forms a seal relative to the valve seat; wherein the holder, actuator and poppet are positioned within a second cross sectional area parallel to the first cross sectional area when in at least one of the open and closed configurations, said second cross sectional area bounded by a parallel cross section of the first cross sectional area; a housing extending about the holder poppeted actuator with the housing defining a tube and said plug being a first end plug connected at a proximal end of the tube; and
a second end plug connected to a distal end of the tube; andwherein the second end plug further comprises a passage in communication with a proximal end of the second end plug, an outlet normally in communication with the passage, a post extending through a portion of the end plug, a seal located at a proximal end of the post, said seal operable intermediate an open and a closed configuration, said seal normally in the open configuration wherein the passage and outlet are in fluid communication, and upon movement of the post, said seal obstructing communication from the passage to the outlet thereby placing the second end plug in a closed configuration. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
