Latest Patents

One of Bader's latest innovations is the electromagnetic unit fuel injector. This device is designed for use in diesel engines and features a housing that contains a pump. The pump is defined by a cam actuated plunger that is reciprocable in a bushing. This mechanism supplies fuel through a discharge passage in the housing to a spring-biased, pressure-actuated injection valve. The valve controls the flow discharge out through the spray tip outlet at one end of the housing. Additionally, the discharge passage connects to a low-pressure fuel drain passage, with flow being controlled by a normally open electromagnetic valve. During the pump stroke of the plunger, the electromagnetic valve is energized to block flow from the discharge passage, allowing the pressure of fuel to increase and effect the unseating of the injection valve.

Another version of the electromagnetic unit fuel injector also includes a pump in the form of a cam actuated plunger. This design supplies fuel at high pressure to a variable volume pressure accumulator chamber. The flow is then directed through a flow control orifice to a control chamber, which is in supply flow communication with a fuel injection nozzle assembly. The pressure-actuated injection valve controls the injected charge of fuel from the unit. The flow through the control orifice into the control chamber is selectively managed by an electromagnetic valve assembly, which also controls the flow from the control chamber through a drain orifice to a low-pressure fuel return line.
