Disclosed herein is a valve construction comprising a main body having therein a bore extending along an axis, adapted to contain fuel under pressure, and having, at the axially outer end thereof, an axially outwardly diverging conical surface extending at a first acute angle to the axis, and a needle valve located in the axial bore, movable relative to the main body between open and closed positions, and including a stem portion, and a head portion including a first diverging conical surface which extends axially outwardly from the stem portion at a second acute angle greater than the first acute angle and terminates in a first edge which, when the needle valve is in the closed position, sealingly engages the conical surface of the main body, and which has a diameter, a second surface which extends axially outwardly from the first edge in increasingly spaced relation from the conical surface of the main body and then in decreasingly spaced relation from the conical surface of the main body and which terminates in a second edge having a diameter substantially greater than the diameter of the valve edge, and a diverging conical surface which extends axially outwardly from the second edge and which, when the needle valve is in the closed position, is located in slightly spaced parallel relation to the conical surface of the main body.

A valve construction comprising a main body having therein a bore extending along an axis, adapted to contain fuel under pressure, and having, at the axially outer end thereof, an axially outwardly diverging conical surface extending at a first acute angle to the axis, and a needle valve located in said axial bore, movable relative to said main body between open and closed positions, and including a stem portion, and a head portion including a first diverging conical surface which extends axially outwardly from said stem portion at a second acute angle greater than said first acute angle and terminates in a first edge which, when said needle valve is in said closed position, sealingly engages said conical surface of said main body, and which has a diameter, a second surface which extends axially outwardly from said first edge and radially outwardly from axis and which terminates in a second edge having a diameter substantially greater than said diameter of said first edge, and a diverging conical surface which extends axially outwardly from said second edge and which, when said needle valve is in said closed position, is located in slightly spaced parallel relation to said conical surface of said main body.
