Title: The Innovative Contributions of Dan B. Kuiper

Introduction

Dan B. Kuiper is a notable inventor based in Grand Rapids, MI (US). He has made significant contributions to the field of engineering, particularly in the development of advanced fuel injection systems. With a total of 4 patents to his name, Kuiper's work has had a substantial impact on diesel engine technology.

Latest Patents

One of Kuiper's latest inventions is the electromagnetic unit fuel injector designed for use in diesel engines. This innovative injector features a housing that contains a pump, defined by a cam actuated plunger that is reciprocable in a bushing. This design allows for the efficient supply of fuel through a discharge passage to a pressure actuated injection valve. The valve controls the flow of fuel discharge through the spray tip outlet. Additionally, the injector includes a low-pressure fuel drain passage, with flow control managed by a normally open electromagnetic valve. This mechanism ensures that during the pump stroke of the plunger, the electromagnetic valve is energized to block flow from the discharge passage, allowing for increased fuel pressure and effective unseating of the injection valve.

Another significant patent by Kuiper involves a similar electromagnetic unit fuel injector, which also utilizes a cam actuated plunger to supply fuel at high pressure. This design incorporates a variable volume pressure accumulator chamber and a flow control orifice that communicates with a fuel injection nozzle assembly. The injection valve in this system is pressure actuated, controlling the injected charge of fuel. The flow through the control orifice is selectively managed by an electromagnetic valve assembly, which also regulates flow through a drain orifice to a low-pressure fuel return line.
