Abstract: A fuel injector apparatus and method is provided for use in a fuel injection system of an internal combustion engine that includes a body, a valve seat, closure member, and an orifice plate. The valve seat comprises the intersection of two angled surfaces with a radius before assembly of the fuel injector. During assembly of the fuel injector, a member presses against the radius edge of the sealing surface of the valve seat to create an oblique third sealing surface or sealing band that is coined into the valve seat. The sealing band provides an improved seal between the valve closure member and the valve seat which operates to prevent leakages of fuel in the fuel injector.

Abstract: A gasoline unit injector includes a high speed, high force actuator such as a magnetrostrictive or piezoelectric actuator. The actuator operates a positive displacement diaphragm pump. The pumping volume is isolated from a supply rail by an inlet check valve, and is isolated from the engine manifold by an outlet check valve. Each of the check valves includes a disk having a central anchor and a peripheral valve seat. Diaphragm movement reduces pump volume and thereby displaces fuel at high pressure through outlet valve. Fuel spray is formed by geometry of outlet valve, the frequency of actuation, and mass and pressure of the displaced fuel. Relaxation of actuator, and therefore diaphragm, increases pump volume and thereby draws fuel into pump volume through the check valve.

Abstract: A dispensing system for dispensing a viscous, flowable product such, for example, as a spin-art paint solution, comprises an axially extending container that defines an opening and an interior chamber for receiving and storing the flowable product. A discharge assembly is coupled to the container, the discharge assembly being dimensioned and arranged to spin, relative to the container, as it receives the flowable product from the interior chamber. The spinning motion of the discharge assembly, which may be accompanied by a linear movement of the container itself relative to a target surface, allows the user to cleanly and evenly distribute the flowable material onto a target substrate in an attractive, curvilinear deposit pattern. Optionally, the discharge assembly may be configured with a pivoting nozzle that can be moved from a position for obtaining a helical (curvilinear) deposit pattern to a position for obtaining a rectilinear deposit pattern.

Abstract: An echo chamber including a high-strength, structurally rigid receptacle and a weight bearing grate through which the water from an artificial outdoor waterfall may pass, which grate can support considerable weight loads exerted by materials such as rocks, stones, and the like. The receptacle functions as a substitute for a flexible artificial waterfall water sump liner and receives recirculating water of an artificial waterfall. When constructing a disappearing artificial waterfall using a chamber constructed according to the present invention, rocks or other material are placed on the chamber's grate. As water cascades through the material on the grate and falls into the chamber, an echo sound is generated. Differing configurations of the stones on the grate and changes in water level in the receptacle produce echoes of different pitch and intensity.
