Abstract
A nozzle includes a body with a hollow interior. An inlet is provided in one exterior surface of the body, the inlet being in an open communication with the hollow interior. An outlet is provided in a different exterior surface of the body, the outlet being in an open communication with the hollow interior. The outlet may have a shape that is different than a shape of the inlet. The outlet may have an area at the different exterior surface of the body being equal to an area of the inlet at the one exterior surface of the body. The nozzle may be used to broadcast mechanical foam.
Claims20
A nozzle, comprising:
- a body;
- a hollow interior;
- an inlet in one exterior surface of the body, the inlet being in a fluid flow connection with the hollow interior;
- an outlet in a different exterior surface of the body, the outlet being in the fluid flow connection with the hollow interior;
- and
- a continuous straight surface portion within the hollow interior between the inlet and the outlet;
- and
- the outlet having a shape being different than a shape of the inlet;
- the outlet having an area at the different exterior surface of the body being equal to an area of the inlet at the one exterior surface of the body;
- wherein the inlet, the outlet, and the hollow interior being configured to convert a shape of a bubble in a mechanical foam from an elongated shape at the inlet into a spherical shape at the outlet.
7 more elements
A nozzle, comprising:
- an inlet surface with an inlet port in the inlet surface, the inlet port having a first shape;
- at least one outlet surface with an outlet port in the at least one outlet surface, the at least one outlet surface being disposed at an incline to the inlet surface, the outlet port having a second shape, the second shape being different than the first shape, the outlet port having an area being equal to an area of the inlet port;
- a hollow inlet portion extending from the inlet port toward the outlet port, the hollow inlet portion having a cross-sectional shape being identical to the first shape, an end of the hollow inlet portion disposed at a distance from the outlet surface;
- and
- at least one hollow outlet portion extending from the outlet port toward the inlet port, the at least one hollow outlet portion having a shape being identical to the second shape of the outlet port, the at least one hollow outlet portion intersects each of a surface of the hollow inlet portion adjacent the end thereof and a surface of the end to provide a passageway from the inlet port to the outlet port, a size of the at least one hollow outlet portion at an intersection with the hollow inlet portion being smaller than a size of the hollow outlet portion at the outlet port, a portion of the passageway being defined by a combination of the hollow inlet portion and the at least one hollow outlet portion configured to intersect and overlap one another, wherein the at least one hollow outlet portion being further configured to reduce in size in a direction toward the inlet surface, and wherein the cross-sectional shape of the hollow inlet portion being generally constant in area and being continuous from the inlet surface to an intersection with the at least one hollow outlet portion.

A nozzle, comprising:
- a nozzle body, comprising:
- an inlet nozzle body portion with an inlet surface and an inlet port in the inlet surface,
- an outlet nozzle body portion with an outlet surface and an outlet port in the outlet surface, the outlet surface being disposed at an incline to the inlet surface,
- the inlet nozzle body portion and the outlet nozzle body portion defining a common flat exterior surface of the nozzle body, the common flat exterior surface connecting the inlet surface with the outlet surface,
- the outlet surface being further disposed at the incline to the common flat exterior surface, and
- a wall of the outlet nozzle body portion being disposed at another incline to the common flat exterior surface;
- an inlet cavity in a fluid flow connection with the inlet port, the inlet cavity extending, along an axis disposed in a plane being parallel to a plane of the common flat exterior surface, from the inlet port into the outlet nozzle body portion, the inlet cavity having a round cross-sectional shape in a plane normal to the axis;
- and
- an outlet cavity in the outlet nozzle body portion and in the fluid flow connection with the outlet surface, the outlet cavity having an elongated cross-sectional shape, the outlet cavity and the inlet cavity being configured to intersect one another to define an interior hollow portion with a combination of the round cross-sectional shape and the elongated cross-sectional portion.
