Abstract: An emergency eyewash unit includes a pair of water discharge ports oriented to produce a pair of upwardly directed, diverging water streams for inside-out flush flow of contaminants from a person's eyes. These eyewash streams can be combined with a plurality of smaller upwardly directed facewash streams for flushing contaminants from a person's face. The eyewash and/or facewash streams are produced by an eyewash body adapted for rotatable mounting onto a water supply conduit, with a locking clip normally preventing undesired rotational disassembly. The eyewash body may be used in combination with an overhead emergency shower which, in one preferred form, includes a shower spray head carrying multiple flow control and flow shaper elements to produce a substantially uniformly dispersed shower spray pattern.

Abstract: An apparatus for controlling a flow of fluid in an emergency fixture is disclosed. The apparatus comprises a first control element at least partially located in the body and configured to impart rotation into the fluid flow. The second control element comprises an inlet that receives fluid, and an outlet that divides the fluid flow into at least a first portion and a second portion. The outlet comprises a first outlet portion and a second outlet portion. The first outlet portion guides the first portion of the flow out of the flow rotation element as an axial flow, and wherein the second outlet portion provides rotation to the second portion of the flow relative to the axial flow.

Abstract: An apparatus for regulating fluid flow through a spray nozzle comprising a circular chamber (1) defined by spaced apart end walls, a peripheral side wall (3), a central axis, and a first inlet at or near the peripheral side wall (3) to allow a flow of fluid to enter said chamber (1) tangential to the peripheral side wall (3), and an outlet (4) exiting through one of the end walls. In use a flow of fluid entering through the first inlet has a primary lower layer (16) that follows a first circular flow path which forms a vortex commencing at the peripheral side wall (3) and increases in velocity and pressure towards the outlet and at least one secondary upper layer (17) that substantially follows a second flow path radially inwardly towards the central axis. The primary lower layer (16) and the secondary upper layer (17) interact and support each other over at least a portion of flow between the inlet and outlet (4).

Abstract: An indexing nozzle assembly for a trigger sprayer has a manually rotatable cap mounted for rotation on a liquid spinner of the nozzle assembly. Rotation of a cap changes the nozzle assembly between an off condition, a spray condition, a second off condition, and a stream condition of the liquid discharged from the nozzle assembly. The cap can be rotated from the off position directly to either of the spray or stream positions by rotating the cap one-quarter turn in opposite directions. A spatial relationship between an end surface of the liquid spinner and an interior surface of the cap end wall that surrounds the assembly discharge orifice improves the stream configuration of liquid discharged by the nozzle assembly.

Abstract: A fuel injector (1) is described, particularly for fuel injector systems of internal combustion engines, including an actuator (27), a valve needle (3) actuatable by the actuator (27) for actuation of a valve-closure member (4), which together with a valve-seat surface (6) forms a sealing seat, and a swirl device (15), having at least one swirl channel (18) through which fuel flows having a tangential component regarding a longitudinal axis (26) of the fuel injector (1). The axial position of a bypass disk (17), which is mechanically linked to a valve needle (3), determines a cross section of at least one bypass channel (19), which bypasses the at least one swirl channel (18) without a tangential component.

Abstract: A pressurized liquid dispensing container and valve assembly comprises an essentially upright container for containing under pressure a liquid to be dispensed and a discharge valve assembly above the container. The valve assembly includes a valve body and a nozzle having a discharge opening that is controlled by a valve. The valve includes a frustoconical valve seat formed in an end wall of the nozzle, and a frustoconical valve head which is axially movable between an inward seating position and an outward position in which the valve is open. A protective cap is screw threaded on the outside of the nozzle and has a discharge aperture in its outer end wall. The valve head has an outer end surface that normally abuts against an inside surface of the cap so as to restrict flow from the nozzle through the discharge aperture in the cap. The cap when screwed tightly holds the valve closed. Partial unscrewing of the cap adjusts the amount of valve opening and rate of liquid discharge.

The spray nozzle comprises a nozzle housing for mounting, for example, onto a hose end trigger valve or the like and supporting a stem unit for receiving the supply of water under pressure. A pair of flow control sleeves are carried by a perforate faceplate for sliding movement relative to the stem unit and nozzle housing to define different water flow paths leading respectively from the stem unit to different nozzle outlets formed by the faceplate in cooperation with the stem unit and nozzle housing.

Abstract: A nozzle body that provides a substantially uniformly distributed spray over 180.degree. at the discharge end in which the uniformly distributed spray in the form of solid cone is created by an inner nozzle and a uniformly distributed spray of a hollow cone is created by an outer nozzle and in which the spray from the inner and outer nozzles are immediately adjacent one another. The construction of the nozzle body is such that although the inner and outer nozzle each initially create their own spray pattern, the end result is a combined solid cone spray that could not be created by either the inner or outer nozzle alone. The nozzle body has a center vane for the inner nozzle to ensure an inner solid cone spray and may have a metering plate to direct some fluid to the outer nozzle so that the end result is a spray that is a solid cone with an angle substantially in excess of the cone created by the inner nozzle alone and having a coefficient discharge of approximately 0.99.

Abstract: A child-resistant nozzle in combination with a hand operated sprayer is disclosed. The nozzle and the discharge end of the sprayer are movable into positions of relative adjustment including a liquid flow OFF position and one or more liquid flowing positions and have cooperating surfaces in which passages are formed, which passages when brought into register by relative adjustment of the nozzle and discharge end determine the mode of liquid discharge, i.e., SPRAY or STREAM. Locking members are also provided on the nozzle or discharge end which cooperate when engaged by other parts of the device to prevent sprayer operation by preventing relative adjustment of the nozzle and discharge end from said liquid flow OFF position without the application, simultaneously, of discrete, predetermined actions of the members and parts.

Abstract: A two-piece nozzle for use on hand actuated pump dispensers is disclosed. The nozzle features a tubular member, which may be a part of the main body of the pump, having a circular, planar face at its terminal end. A hollow bore extending through the tubular member and the hollow face is in liquid passage communication with a recess in the planar face. A cap is rotatably mounted to the tubular member and has an end wall with a planar inside surface which will form an interface with the circular planar face of the tubular member. Radially displaced from the center axis of the circular skirt is a dispensing orifice which is registerable with the recess present in the planar face of the tubular member. A sealing boss surrounds the dispensing orifice and bore to provide a liquid-tight seal with the planar face when the orifice is not in registration with the recess. Mounting structure is provided on the cap and tubular member for achieving a rotating mount of the cap to the tubular member.

Abstract: An adjustable nozzle assembly for a hand operated compression sprayer is disclosed. The nozzle is attached to the discharge end of the sprayer and is adjustable from an off position to two discharge positions, such as a spray position and a stream position. The nozzle and sprayer body have cooperating passages which, when brought into register by adjustment of the nozzle, determine the discharge mode (i.e., whether off, spray or stream).

Abstract: A nozzle located at the discharge end of a container includes a tubular member and a cap thereon. The tubular member has a passage in communication with the container interior for passage therethrough of the container contents to be dispensed. The cap is adjustably mounted on the tubular member and is capable of being turned to a first position at which the passage of the tubular member is closed to prevent the passage of the material to be dispensed. The cap is adapted to be turned to a plurality of discharge positions depending upon the discharge pattern desired. In these positions the passage is open and is placed in communication with a discharge opening and surrounding recesses in the closed end of the cap through a passageway defined by cooperating surfaces of a slotted core portion and surrounding slotted core skirt of the tubular member and a slotted boss cooperating with the core and skirt of the tubular member when the cap is assembled to the tubular member.
