Title: Innovations by Steven P Martin

Introduction

Steven P Martin is an accomplished inventor based in West Covina, CA. He has made significant contributions to the field of turbocharger technology, holding 2 patents that showcase his innovative approach to engineering.

Latest Patents

One of his latest patents is for a variable geometry turbocharger. This invention employs multiple vanes in the turbine inlet, featuring a unison ring and integral cast wall in the turbine housing that forms the nozzle walls. The unison ring incorporates actuation slots that receive tabs on the vanes, allowing for the opening and closing of the nozzle area upon rotation of the unison ring. An integral electrohydraulic actuator rotates the unison ring through a rack and pinion driven crank shaft, providing direct position feedback to the spring biased variable current solenoid via a cam on the crank shaft.

Another notable patent is for a direct acting rotary actuator for a turbocharger variable nozzle turbine. This axial to rotational motion actuator employs two sets of engaged helical splines on rotational collars, providing a large degree of rotary actuation from a relatively short axial stroke. This design results in efficient non-binding and reduced effort actuator operation. The improved actuation movement makes the actuator assembly more responsive to hydraulic activating means, such as oil pressure, and enables compact packaging of the actuator assembly to optimize available space around a turbocharger and inside an engine compartment.
