DETAILED DESCRIPTION
Referring to FIG. 1, a nozzle (1) has a nozzle body which includes a cylindrical pipe (6), a nozzle end cap (8), and an end cap retainer (9). The pipe (6) has a central opening (7) therethrough, is internally and externally threaded at one end thereof and has an opening (6A) therethrough at a location spaced a small distance from the threaded end.
A member (2) is disposed within the nozzle body and, as shown in FIG. 2(B), has three angularly spaced, radially outward projections (5) thereon which each have threads at the outer end thereof which threadedly engage the internal threads on the pipe (6). The surface of the upstream end (2A) of the member (2) is curved and in the illustrated embodiment is an ellipsoid. A generally planar end surface (2B) is provided at the downstream end of the member (2), and the member (2) has a frustoconical surface (2C) which is adjacent and converges toward the end surface (2B). A cylindrical passageway (4) extends coaxially into the member (2) from an opening in the end surface (2B) thereof. A threaded, radially extending opening (2D) is provided in the member (2), and is perpendicular to and communicates with the passageway (4) at the rightmost end thereof. The threaded opening (2D) is aligned with the opening (6A) in the pipe (6), and a fluid inlet conduit (10) having a central opening (11) therethrough extends snugly through the opening (6A) and has an externally threaded end which is disposed in and threadedly engages the opening (2D).
The frustoconical surface (2C) on the member (2) has a plurality of angularly spaced grooves (3) therein which, as shown in FIGS. 2(A) and 2(B), each have a bottom wall (e) and two spaced side walls (b) and (c). As shown in FIG. 1, the intersection of an extension of the cylindrical surface of the passageway (4) and the frustoconical surface (2C) is a circle (v') which lies in a plane substantially parallel to the end surface (2B) of the member (2). The bottom wall (e) and the side walls (b) and (c) of each groove converge toward a point of convergence lying on the circle (v'). As shown in FIG. 2(B), the side walls (b) and (c) of each groove each follow a logarithmic spiral, the center line (a) of each groove being an arc which, in FIG. 2(B), is approximately tangential to the circle (v') and has a center point (Q) which is closer to the circle (v') than to the apex (v) of the extension of the frustoconical surface (2C).
As shown in FIG. 5, the nozzle cap (8) has an end surface (8A) thereon with an opening (8B) therein which communicates with a passageway (8C) through the nozzle (8). The surface of the passageway (8C) is a frustoconical surface which converges toward the opening (8B). The nozzle cap has a radially outwardly extending annular flange (8D). As shown in FIG. 4, the noz
