ABSTRACT:
A poppet-type valve unit having annular elastomeric poppet which cooperates with an annular valve seat. The exterior profile defined by a pair of generally frusto-conical surfaces which are disposed radially inwardly and outwardly with respect to one another. The inner frusto-conical surface extends at a steeper angle or slope relative to valve movement direction than does the outer frusto-conical surface, thereby defining a peak where the two frusto-conical surfaces meet. This peak substantially corresponds in diameter to the diameter of the valve seat. This increases the flow area between the poppet and valve seat when the poppet is opened.
