Abstract
A sealing device of a delivery valve having a valve holder accommodating a valve body, and a valve seat fitted into an opening of the valve holder. The end portion of the valve holder has an end face thereof formed with an annular radially outer slant face moderately slanting with respect to an open end plane perpendicular to an axis of the valve holder, and an annular radially inner vertical face extending continuously from the annular radially outer slant face along a plane perpendicular to the open end plane, thereby ensuring positive sealing between the valve holder and the valve seat.
