ABSTRACT:
A probe and a valve, which may be used together in a valve assemblage, and a method of using them. The valve includes a valve body with a forward end having a forwardly tapering valve body opening defined by a valve seat; a valve seal positioned in the valve body and having a forward end with a forwardly tapering valve seating portion, with the forward end being movable rearwardly from a closed position in which the seating portion sealingly mates against the valve seat to close the valve body opening, to an open position in which the valve seating portion is spaced from the valve seat to allow fluid to pass through the valve body opening and hence through the valve; and a resilient member adapted to urge the forward end of the valve seal into the closed position.
