Title: Thomas G. Elphick: Innovator in Engine Technology

Introduction

Thomas G. Elphick is a notable inventor based in Hilton, NY (US). He has made significant contributions to engine technology, holding 2 patents that showcase his innovative approach to mechanical engineering.

Latest Patents

One of his latest patents is the "Camshaft Phasing Drive with Wedge Actuators." This invention features a phase adjuster for engine camshafts that includes a sprocket driving a camshaft attached hub through paired wedge packs. These wedge packs transfer torque and maintain a lash-free connection. A plunger, actuated by engine oil pressure, moves alternate active wedges to vary the arcuate lengths of the wedge packs, thereby changing the phase angle between the sprocket and camshaft. Additionally, a three-way valve minimizes oil flow requirements by shutting off pressure oil flow except when needed to advance the plunger.

Another significant patent is the "Fuel Rail Assembly." This assembly is designed for a V engine and consists of a pair of fuel rails connected by crossover and discharge conduits. The conduits are secured to the fuel rails in a manner that allows relative motion between the fuel rails without losing fuel from the fuel rail-conduit intersection.
