초록

A high pressure valve of the type employing a non-rotating valve needle having a tapered tip which may be selectively moved between seated and unseated positions relative to a valve seat in a valve chamber. The valve seat is tapered inwardly and has a smaller taper angle than the valve needle. A valve actuating stem is received through a valve packing nut with the actuating stem having a bifurcated inner end defined by a transverse, generally rectangular bore intersected by an axially directed slot. The slot is somewhat smaller in breadth than the width ...
