A high speed rotor intercepts only the boundary layer of the jets in a manner to impact violently upon the boundary layer. This produces a novel mode of operation in which water exits the jet along its length as vapour to form a mist of find droplets.

Abstract: A valve sound emitted from an operated injector is suppressed to be transmitted through a fuel passage in a core to a delivery pipe, thus reducing operating noise. A sound insulating member is fixed in the fuel passage in the core. It has been recognized that transmission of the sound is effectively suppressed even with a sound insulating member of such a size that does not prohibit fuel flow. Preferably, the sound insulating member is integrally assembled to a strainer. Noise from the operated injector is effectively reduced by the invention.

Abstract: An improved fuel injection valve for improving the flow of fuel includes a vortex forming member and a needle valve having a planar surface on its leading end. A valve seat has a fuel injection nozzle formed therein and the needle valve opens and closes the fuel injection nozzle by engaging and disengaging with the valve seat. The vortex forming member provides a vortex motion to the fuel entering the fuel injection nozzle, upstream of a seat portion. The flat portion reduces the amount of surface area in which particles may adhere, thus preventing particles from adhering to the needle valve and reducing interference with the flow of fuel.

Abstract: A machine for distributing material over crops comprises a vehicle for moving across the ground together with a single boom which projects out from one side of the vehicle over a length which can be of the order of 120 feet. The boom is self-supporting and formed by four rails at the corners of a rectangle together with a plurality of sets of spaced cross struts and longitudinal cables so that each of the rails is under compressive load. The boom is thus self-supporting and is coupled to a center cradle only at the ends of the rails. The boom can be broken down into separate sections. The cradle is a rectangular frame structure which is suspended on a horizontal tubular beam by a sleeve surrounding the beam having a diameter slightly bigger than the beam so that pivotal movement of the cradle tends to roll the sleeve around the beam thus lifting the center of gravity and dampening the pivotal action.

Abstract: A rotatable high pressure tool for cleaning hollow objects by forcing a high pressure fluid such as water from nozzles to create cleaning jet streams and use jet reaction at the tool to continually change the direction of the jet nozzles about a longitudinal axis of the tool while the jets are carried by a cross body rotating about an axis essentially perpendicular to the longitudinal axis. Each of the nozzles provides the same amount of reaction torque to rotate the cross body about its axis. This torque is selectively adjustable at the tool before use by similarly releasing, changing and reclamping the orientation of all nozzles relative to the cross body and by changing the discharge diameters of uniformly sized nozzle tips. The adjustable nozzles are interconnected by gearing so that the changes in orientation of all nozzles during adjustment will be the same.

Abstract: A liquid atomizer for, e.g., fuel, comprises a tube having an opening for receiving pressurized liquid flow. The tube has a closed end, a wall, and one or more bores through the wall. A shell having a discharge end with a discharge orifice encircles a portion of length of the tube, including the tube closed end. The shell forms an annular chamber around the tube end and an end chamber between the closed tube end and the shell discharge end.

Abstract: A high volume low pressure air spray gun has an atomizing air orifice for atomizing a stream of liquid coating material into a conical spray and opposed side port air orifices for flattening the spray into a fan-shaped pattern. The gun receives air at pressures up to about 100 psi, and an air flow restriction in the form of a venturi is in an air supply passage in the gun barrel. A valve stem for controlling the flow rate of air to the side port orifices extends through the venturi, and is configured to vary the venturi air flow area in response to changes in the flow rate of air to the side port orifices. When the valve stem is positioned for maximum air flow to the side port orifices, it establishes a maximum air flow area through the venturi, such that a high pressure of air at the gun air inlet, after flowing through the venturi, results in a high volume low pressure air flow at the atomizing and side port orifices.
