Abstract: An injection valve can compensate for the reduction in through-flow experienced with known valves operating at higher temperatures. By forming the valve needle and valve seat carrier from different materials and more particularly by using a material with a very low coefficient of thermal expansion for the valve needle, the valve needle expands less in comparison with the valve seat carrier when there is an increase in temperature. Thus, an increase in travel occurs and a reduction in the metered quantity of fuel due to the formation of gas bubbles is avoided. The injection valve is particularly suitable for use in fuel injection systems of mixture-compressing, spark-ignition internal combustion engines.

Abstract: An electromagnetically actuated fuel injector supplies fuel to an internal combustion engine. The injector has a body with an inlet and a nozzle. A needle valve is selectively moveable within the body in response to actuation of the fuel injector. A reduced center-body coil spring is disposed within the fuel injector and biases the needle valve in a closed position. The reduced center-body coil spring has a substantially hour glass shape to prevent rubbing with the components of the fuel injector.

Abstract: A fire hose nozzle cover apparatus (10) for a fire hose nozzle (12) includes cover structure (28) configured for covering at least a portion of a fire hose nozzle (12). The cover structure (28) broadly includes an end wall (30) and a tubular sidewall (32). The sidewall (32) has a first margin (34) coupled with and circumscribing the end wall (30) and has an opposed second margin (36). The end wall (30) and sidewall (32) cooperatively define a recess (38) for receiving and enclosing the nozzle (12) therein. Once the nozzle (12) is received in the recess (38), the second margin (36) of the sidewall (32) is then cinched about the rearward end (18) of the nozzle (12) to secure the nozzle (12) within the cover structure (28).

Abstract: The shower spa fixture is mounted between an inlet pipe and a shower head and includes a container for mixing a stream of water with additives. A portion of the stream of water passing from the inlet pipe to the shower head is diverted into the container. The container includes a replaceable cartridge which has a first additive in a first chamber and a second additive in a second chamber. The diverted stream of water mixes with the first additive in the first chamber, passes through a screen to the second chamber, and mixes with the second additive in the second chamber. The diverted stream containing additives is then returned to the main stream of water which exits the shower head. The amount of additives added to the main stream of water is controlled by a control valve. The present invention provides an improvement over known arrangements by providing two additives which are kept separate from one another preventing a chemical reaction between the additives which would cause a loss of potency.

Abstract: A vehicle mounted spray system includes a variable orifice spray nozzle and control apparatus to correlate the delivery of pressurized fluid spray product to the nozzle in a selected ratio to the ground speed of the vehicle. The spray nozzle includes a circular orifice with a conical valve seat and a fluid pressure responsive, spring biased, conical shaped needle valve element mounted for reciprocation therein. The taper of the valve element is less than the taper of the valve seat and the apex of the needle valve protrudes beyond the orifice to create a solid stream flow of the spray product. The solid stream spray is projected onto the surface traveled in a direction opposite the direction of travel and at an angle therewith. The nozzle velocity of the spray product is equal to or greater than the vehicle velocity.

Abstract: A child-resistant, wick-based liquid emanation system includes a container which is capable of containing liquid and has an opening. A wick is partially disposed within the container and extends through the opening of the container. A hollow overcap encases the extended portion of the wick and has a closed, separable tip and an open base attached to cover the opening of the container. The system is activated by separating the tip from the overcap. A retainer may be provided for obstructing complete removal of the wick from the container through the overcap after the tip is separated from the overcap. The retainer can include a shoulder disposed in the overcap between the tip and the base to retain the wick toward the base of the overcap. Alternatively, a protrusion from the wick can engage an inner surface of the overcap or the container. In this case, the overcap can have a frangible portion facilitating separation of the tip, and the wick can extend past the frangible portion toward the tip.

Abstract: A device for releasing a volatile substance into an environment in a controlled/metered manner. A reservoir made of a substance-absorbent material that is impregnated with a volatile substance in its liquid phase is located in a cavity open at the front surface of a container body made of a material non-permeable to the substance. A wood or wood-type panel permeable to the substance covers the cavity. A clip may be fixed to the back surface of the container body so that the device may be secured to a mounting surface. The device may be packaged with skin pack film such that a vapor barrier is formed, preserving/storing the substance until such time as opened/activated by the consumer. When activated, a volatilization mechanism is initiated wherein the panel absorbs the substance from the reservoir, the substance is introduced to ambient air, volatilized, released and, finally, dispersed throughout an environment.
